Gaining Weight to Lose Weight: Fixing a Damaged Metabolism

Gaining Weight to Lose Weight: Fixing a Damaged Metabolism by Increasing your Calories

This is going to sound crazy but there are certainly some of you out there who will ultimately end up needing to gain weight before you lose weight. 

And the way that you should do this is by increasing the number of calories that you consume. 

This information does NOT apply to everyone but it may apply to you, especially if you are someone who has been chronically reducing your calories in order to maintain a specific weight. 

Let’s break down why this matters and if it applies to your specific situation. 

*Note: the information here primarily applies to people with severe metabolic damage from yo-yo dieting, eating disorders, or severe or undertreated thyroid conditions. 

The Connection Between your Weight and Your Metabolism

Despite weight being a massive problem for many people, we still don’t fully understand all of the factors involved in both weight gain and weight loss. 

No one would dispute that factors such as calories, hormones, and metabolism all play an important role in regulating weight. 

But we don’t quite understand how all of these factors play together and which factor is most important. 

I would submit to you, based on my evaluation of the research and my own personal experience, that metabolism is probably one of the most important elements in understanding why we gain weight and how to lose it. 

Calories and hormones fit into the equation because they both manipulate metabolism, but metabolism sits front and center in terms of how it influences your weight. 

And studies show that it is incredibly important. 

We know, for instance, that having a normal metabolism is a strong predictor for maintaining a normal healthy weight (1) and for also keeping weight off once you lose it. 

The question really becomes what factors negatively (and positively) impact your metabolism and how can we take advantage of these factors to promote sustained weight loss. 

Calorie Restriction Leads to Metabolic Damage

Isn’t cutting calories the way that you lose weight?

Well, yes and no. 

The traditional way that we think about losing weight has less to do with how many calories you consume and more to do with how the calories you consume interact with the hormones in your body. 

But, there is no question that reducing your calories will result in some weight loss. 

But this weight loss is typically only temporary and does not last. 

“Although they are initially successful in producing weight loss, such lifestyle intervention strategies are generally unsuccessful in achieving long-term weight maintenance, with the vast majority of obese patients regaining their lost weight during followup.”

And the more times that you “count” or reduce your calories the more damage you will do (3), the longer it takes to lose the same amount of weight that you lose before, and the more aggressive you will have to be with counting your calories. 

Let’s say that you are someone who is 20 pounds overweight and you want to lose that weight. 

You jump on an aggressive diet such as the hCG diet

You lose 20 pounds by cutting your calories to 500 per day over a 60-day period. 

You keep that weight off for 6-9 months but you notice that it eventually all comes back. 

At this time, with all of your weight back, you want to try and lose it again. 

So you do what worked before, the same hCG diet, only this time it takes more than 60 days, and instead of losing all of your weight you only lose 5-10 pounds. 

This cycle typically repeats itself and the people who do it damage their metabolism more each and every time. 

Ultimately, if you continue, you will get to a point where you will be consuming 1,000 calories per day just to maintain your weight. 

And if you fit into this category then this article is definitely for you. 

The question is, why does this happen? 

Most research points to a condition known as metabolic adaptation (4). 

Metabolic adaptation is what your body does when you reduce the calories that you consume. 

metabolic adaptation after calorie restriction

You can think of your metabolism like a thermostat which is set by the brain. 

If that thermostat is set to 2,000 calories by your brain (mediated through hormones such as leptin and thyroid hormone) then you will burn that amount each day. 

But when you reduce your calories for an extended period of time, the research points to around 14-21 days, that thermostat gets pushed downward. 

So, instead of burning 2,000 calories per day, your body will only burn 1,600. 

This process takes a few weeks to kick in which is why calorie-restricted diets tend to work initially. 

But the problem comes when you try to get your brain to reset the thermostat and push back up the number of calories that you are burning. 

Your brain doesn’t move very quickly so the thermostat stays low, 1,600 in this hypothetical example. 

This means once you start consuming a regular amount of calories, say 2,000 calories, you will gain all of the weight that you previously lost. 

Make sense?

And we know, from real-world examples such as the Biggest Loser, that once your brain pushes down your metabolic thermostat, it can stay low for years (studies suggest that it stays low for at least 5-6 years (5)). 

metabolism changes in the biggest loser contestants

The question really becomes, what can you do to push that thermostat back up?

If you can increase your metabolism back up to normal then you can actually start to lose weight. 

Increasing your Calories Improves your Metabolism

One major problem when dealing with metabolism is that we really only have a handful of therapies that target metabolism. 

If you take a look at weight loss medications, which you can view as a proxy for how doctors look at weight loss, you will find that most of them target your appetite in some way. 

Most of these medications, including medications such as phentermine, make metabolism worse by further suppressing calorie reduction (6) leading to the cascade mentioned above. 

phentermine works to suppress appetite

This doesn’t mean that these medications are bad, in fact, it’s quite the opposite, but it does mean that they should be used appropriately and in the right setting. 

Of all the weight loss medications available, only a few target the hormone pathways which are responsible for regulating your metabolism. 

And these medications work by altering hormone levels in an attempt to help reset how your brain views fat concentration in your body. 

But is there another way to accomplish the same goal, without taking medications? Or even in conjunction with the right medications?

And the answer is yes.

Diet and the number of calories that you consume heavily influence your metabolism. 

In fact, we know that your brain attempts to closely match your metabolism to the number of calories (7) that you consume. 

It does this by regulating certain hormones such as leptin (8), ghrelin (9), thyroid hormone, and others. 

how leptin works in the body to manage weight

This matching of metabolism to your food intake is well known and is the reason that you can temporarily consume an extra 3,500 calories in one day and not gain an extra pound of fat mass (note this only works if your metabolism is working normally, do not try this experiment if you have a damaged metabolism!). 

1 pound is of fat mass is equal to 3500 calories

If only it were THIS easy!

Your body can temporarily handle either a large influx of calories or a deficit of calories over the course of a few days. 

Just think about it:

What happens when you are sick? You certainly aren’t eating a normal amount (10). 

What happens when you go on vacation or eat over the holidays? You certainly aren’t eating a normal amount. 

Your body is able to handle these small variations but once it extends beyond some time point (usually 2-3 weeks) then problems start to arise. 

It just isn’t realistic to assume that your metabolism is constant and that you are consciously matching the number of calories that you consume to some arbitrary number such as 2,000. 

This occurs subconsciously, without you thinking about it, unless the hormones we mentioned become unbalanced and start to trick your brain with food cravings and so on. 

And these imbalances do start to kick in once you suppress metabolic function through consistent calorie restriction. 

But, you can offset this problem by increasing your calories back to where they should be if you had a normal and healthy metabolism.

As you increase the amount that you consume, your brain will start to push that metabolism back up to where it was before the drop. 

And this is key to maintaining a healthy metabolism. 

Gaining Weight to Lose Weight

If you are someone with severe metabolic adaptation, meaning your metabolism has been severely damaged through decades of repeated yo-yo dieting, then this means you will probably have to gain weight to lose weight later on. 

I understand that this is a very difficult pill to swallow and if you fit into this situation you are probably someone who is very sensitive to your weight, to begin with. 

I do actually understand the paradox that exists here but I am suggesting that, at least currently, there are very few ways to fix the problem. 

One of those ways has to do with increasing the calories that you consume. 

This ultimately leads to weight gain, initially, but it’s necessary for long-term and sustained weight loss. 

And isn’t that what you want? 

You don’t want to temporarily lose another 5-10 pounds with a fad diet. 

get my weight loss supplement bundle and 60 day weight loss program

What you really want (or at least what you should want) is to lose weight and keep it off for good. 

And after you lose it be confident that it won’t come back despite occasional indulgences (moderation in all things, though!). 

Let’s break down how increasing calories increases your weight but helps you long-term: 

Once you increase your calories you will start to gain some weight back. 

The amount of weight that you gain will be proportional to the metabolic damage that exists in your body. 

Let’s use an example to help illustrate this point:

Imagine that you are someone who burns about 1,000 calories per day due to severe dieting over the years. 

You must consume that 1,000 calories each day in order to maintain your weight. 

But even consuming 1,000 calories doesn’t allow for any weight loss, it just keeps you at your current weight which is probably at least 20 pounds over your ideal weight. 

For this example, let’s assume that you currently weigh around 170 pounds and your target weight is around 140. 

If you increase your calories by about 400 per day up to 1,400 per day you can probably expect to gain 5-10 pounds from this small adjustment. 

This will put your new weight around 175-180 pounds. 

And yes, you will be temporarily taking a step backward, but it puts you in a much better position for long-term weight loss. 

Even though you have gained some weight your metabolism should start to reset at this new level, probably around 1,400 calories per day. 

Once you get to this point you should notice an improvement in thyroid function, either a rise or fall in leptin (depending on your base level and sensitivity), and an improvement in symptoms such as hair fall, fatigue, and so on. 

Once you get to this point you can now address those hormone imbalances which affect your weight and you should start to see your weight drop back down. 

You can then repeat this process while closely monitoring your hormones, diet, and weight until you have restored your metabolism to what it was previously. 

Should you do it?

You can imagine that this process is somewhat of a balancing act. 

And you can probably also imagine why many people either don’t do it or aren’t even aware that this therapy exists. 


Because it just doesn’t make intuitive sense that in order to lose weight you must gain it, but once you understand the physiology it becomes apparent why it is necessary for some people. 

The question is:

Should you do it? 

And to that, I would suggest that you proceed with caution, especially if you are someone who fits the patient profile and examples I’ve illustrated above. 

It’s not that the therapy is ineffective or anything like that, but there are many variables and hormones that should be monitored throughout the process. 

In addition, the process can be quite confusing unless you have some experience doing it. 

The process of gaining some weight to lose it later can also be very frustrating as a patient, especially if you aren’t confident you are doing it correctly. 

I can confirm, however, that I have successfully done this with many patients successfully and have helped them improve their metabolism and ultimately lose weight. 

Even when done correctly the process can still take many months, however, so you should be aware of that. 

I find that this therapy is also particularly effective for those patients with difficult-to-treat patient populations such as those with a history of anorexia/bulimia or other eating disorders. 

I will also briefly point out that some procedures have shown promise in restoring metabolic function. 

Procedures that fit into this category include forced fasted states from bariatric surgery. 

I’m not recommending that you get this procedure done but I am pointing out that some studies show that it can restore metabolic function (11). 

I personally believe that there are more effective ways of restoring your metabolism without permanently (or semi-permanently) altering your gastrointestinal anatomy. 

Does this information apply to you? 

I want to be very clear that this information does not apply to everyone who is overweight. 

I am not trying to suggest that eating more calories is the way to lose weight. 

I’m suggesting that eating more calories may be a strategy necessary to improve metabolic function in certain people. 

This applies specifically to people who are suffering from weight gain and who also have metabolic damage/metabolic adaptation. 

But you have to remember that there are PLENTY of reasons for weight gain outside of metabolic adaptation. 

Inflammation (12), hypothyroidism, illness, medications (13), cortisol abnormalities, lack of sleep (14), poor exercise, poor diet, and so on can all lead to weight gain which does not necessarily compromise your metabolic function. 

The treatment for obesity in these situations is to address the underlying cause. 

If your thyroid is dysfunctional then you should receive treatment with thyroid hormone

If inflammation is leading to obesity then you should consume an anti-inflammatory diet (15) and take anti-inflammatory supplements. 

If you are eating an unhealthy diet then you should eat a healthy diet. 

And so on. 

It’s possible to have both metabolic damage and obesity related to these conditions, but just being overweight does not guarantee that you have metabolic damage. 

In addition, the severity of metabolic damage that exists in your body is also important. 

Minor metabolic damage may not be causing you significant harm or difficulty with weight loss. 

But the more extreme the damage, the more likely you are to need to address it for long-lasting weight loss. 


I’m not suggesting that everyone who needs to lose weight has metabolic damage. 

I’m also not suggesting that consuming more calories is always the answer to weight loss, far from it. 

Instead, I’m suggesting that there are some people, who suffer from severe metabolic damage, who may benefit from the strategies listed here. 

Now I want to hear from you:

Are you someone who suffers from metabolic damage?

Do you suspect that your metabolism is lower than it should be?

Are you maintaining your weight, without losing weight, by reducing your calories every day?

If so, what therapies have you tried? Which has worked for you?

  1. I believe I suffer from Metabolic Damage. I had my Thyroid completely removed in October 2014 (my age was 44 years old) due to Thyroid Cancer, since this time, I have gained 85 lbs. I was overweight to start off, but not near this heavy. I have been trying, ongoing to lose the pounds, however, am seeing my weight go up..? I was diagnosed after the full thyroid removal with Type 2 Diabetes. My Endocrinologists answer in regards to the weight gain is that I am pre-menopause and was not at an ideal weight for her to start at. She put me on Synthroid 200 mcg and Ozempic (for diabetes 0.5 mg weekly) I feel tired all the time, and whatever I eat, healthy, etc.. doesn’t seem to boost my metabolism, so I am hoping your shake supplement will perhaps be something I could try and what else can you recommend? Please let me know.

  2. Very interesting article. I believe I ruined my metabolism in my 20s thanks to “trainers” who basically geared me towards a diet of lean proteins with minimal to no fat. I was on a 1200 calorie diet, consisting mostly of vegetables, chicken breast and egg whites. It wasn’t until my early 30s when I went through pregnancy and nursing that I ate well and upped my calories that I think my metabolism was finally reset and I could go back to eating for hunger rather than the minuscule amounts of food.

    • Hi Dsharp,

      That could certainly be a part of it. I’ve seen a number of women who do much better with weight management after pregnancy.

  3. Dear Dr. Westin Childs,
    I am not sure what category I fit into. I have been very thin my whole life, do not have a history of diabetes, do not have a history of overweight family. I am going through menopause and was recently diagnosed with hypothyroidism. About two years ago I gained an enormous amount of weight in Months – over 60 pounds. I am not tall, am very fine boned, so this is massive for me. I am truly at a loss, and frankly, am terrified. I have just been put on Victoza to help with weight loss. Any insight you could offer would be great. Thank you.

    • Hi Alice,

      If you don’t have a history of yo-yo dieting then your weight gain is probably more related to hormone imbalances as opposed to metabolic adaptation. This makes sense given that it occurred around menopause.

  4. Hi Dr. Childs,

    I am on LDN for hypothyroidism and it really kills my appetite. I find I need to eat way less when I’m on it. Am I at risk for metabolic adaptation with this drug, so is my body self-regulating somehow? I am about 40 lbs overweight.

    • Hi Sarah,

      The only class of medications that I’ve seen which can handle a reduction in calories are the GLP-1 agonists and that’s probably because they attenuate the increase in leptin resistance which occurs after calorie restriction.

  5. I am absolutely sure I suffer metabolic damage. Since my 20’s I have been overweight. I was a patient in the Optifast program in the late 1980s. Began the Optifast program at about 230 lbs and lost 50 lbs.
    I slowly gained that back and simultaneously became hypothyroid w/ Hashimotos. A large goiter was what alerted me. My TSH was extremely high. It kind of freaked the endocrinologist I was referred to out and he started me out on 225 mcg Synthroid. I then lost 100 lbs in 1996 through a self-directed smoothie diet, after getting my thyroid in check. One smoothie a day was pretty much all I ingested but gave myself a free day to eat whatever I wanted on Sunday. That worked well. I got down to 120, gained back to 150 and kept it around there for almost 10 years. Then I became the sole caregiver to my mother who had dementia. 5 years of caregiving, I was isolated and food was pretty much my comfort and I gained it all back. In 2011 when she died, I got back down to 187 through keto, but it all crept back on. I could never get below that obese line.

    This, despite the fact that I teach aerobic/HIIT classes 6 days a week. (for 6 years) Three days a week I teach 3 classes in a row and my fitness tracker shows a calorie burn over 1000 calories after classes on those days. I teach a total of 12 classes a week. Intensity minutes on my tracker is always over 1500 minutes a week.
    I intermittent fast 16/8, teach, fasted, and eat one meal a day in the afternoon. I’m now on 150mcg Levothyroxine and 15 mcg Liothyronine. My labs are all good. Cholesterol, Triglycerides Glucose, A1C, all normal. TSH could be a bit lower @ 1.54, but Reverse T3 is often 26. to 33. (Free T3-3.8) Ratio .14 or worse. All the other thyroid numbers are fairly optimal. Reverse T3 is clearly higher when I keto, so I have tried adding fruit back in. My Reverse T3 does lower when I eat more carbs, but weight loss is still non-existent.
    I love my job. I assume I am increasing cortisol because it is some fairly extreme activity, but it is also keeping all my other lab numbers good. (HDL > 60.) I am 61 and would really like to look like the fitness instructor I am.
    My doctor isn’t concerned about my Reverse T3, but I am convinced that is exactly where my problem is. I’m sure it is high through metabolic damage and calorie restriction and I hope to figure it out. You seem to be very close to helping me figure this all out.

    • Hi Cyndy,

      Reverse T3 may be an important part of the puzzle but I would be very surprised if it is your main issue causing your weight loss resistance. I just don’t see that to be the case in many people.

  6. I’ve been overweight since I was a child and for many years suspected hypothyroidism, but multiple tests never showed anything up. I always ate healthily and as the weight piled on in my 20s I regularly crash dieted. I could never keep the weight off because it’s just not a sustainable way of eating. In my 30s I invented a new way of eating that controlled my weight – “wet season” and “dry season” where I extreme dieted (less than 800 calories a day) for 6 months and then relaxed the rules for the next 6 months. Obviously, this meant I gained and lost 30lbs every year for about 5 years. When I got engaged, I lost 50lbs for the wedding by having an extended dry season- I gained 20lbs just while we were on honeymoon, and the rest soon after, plus more – I am now over 200lbs and have a BMI of over 35. 18 months ago I received my hypo diagnosis and have increased from 50 to 100mmg levothyroxine- it hasn’t helped my weight. I am now on an anti-inflammatory diet (my husband is a nutritionist and personal trainer so I’m not allowed to do wet season and dry season anymore) yet I still can’t lose weight. Your blog post above it’s very helpful, I feel like I can finally understand what is happening to my body. I feel like I need a doctor to help me through resetting my metabolism but after years and years of doctors telling me one hole is bigger than the other and to cut out junk food (!!!!), I’ve never found anyone who even takes me seriously. I understand you’re not taking patients on, but could you recommend someone? I’m from the UK but I live in Costa Rica. Thank you so much for your blog posts, they’re a lifeline!

  7. I find this super applicable to me. I Began to notice patterns (via food journal) where if I decreased my food intake, my weight creeps up, my hair falls/thins and Im stressed. If I increase my food intake, the symptoms slowly abate. I decreased calorie consumption a few months ago and am now trying to go back to where I was before by increasing my food and getting enough sleep! My only concern is how many calories I should be eating and a fear tha the more I eat, I will gain fat.

    • Hi Serene,

      You will most likely gain weight as you increase your calories but the idea here is that it’s necessary in order to improve your metabolism. The reason most people stay overweight their entire lives is that they are afraid to go through this process so they constantly restrict calories and ultimately stay overweight.

  8. How long does the reset typically take? I have been dieting for about 3 years. First, lost 50 lbs but then at the same calorie level intake I gained 10 back. Trying to lose them is extremely hard though I am still restricting. I am very afraid of gaining so trying to understand the length of that reset process. And if I am currently consuming about 15oo calories with an active life style at 44, how much higher in cal intake should I go?

    • Hi JC,

      In my experience, it usually takes several years to improve your metabolism but you aren’t gaining weight during that entire time. The weight gain usually only happens in the beginning when you increase your calories.

  9. If my t3 medicine seems to be at a good place, I’m on 1.5 of LDN and am 38 years old and have one ovary. I’ve off and on dieted for years and have noticed all sudden no matter what I’m gaining weight or just can’t lose it. Particularly about 8-10 lbs worth. Would I prob fall under that category that needs to gain weight to lose it?

    • Hi Lauren,

      It’s too hard to say with this small amount of information. I usually make that decision after discussing the history of a patient for about an hour.

  10. Thank you for such an interesting and helpful article. I am currently in the process of trying to understand the reason for my extreme weight gain. I dieted last year eating 1200 calories and under 25 net carbs (however I only did this for one year and lost 40 pounds). After coming off the diet I have gained 60 pounds and my weight continues to go up despite good eating habits. I am currently seeing an endocronogist and we are evaluating my hormones which have all come back normal. That said, I am still gaining about 1.5 pounds a week and my Dr. suggested cushings, but from my understanding this is a very rare disease and unlikely. Therefore, my question for you is on average if I do have metabolic damage how long do you believe this weight gain will continue (what have you seen in other patients)? Also is gaining this much weight this quickly normal with metabolic damage or could it be something else? Thank you in advance for any help you can provide.

  11. i have gone through a period of intense exercise and low calories for a year. I then decided to increase calories and stop exercise i gained around 10 pounds. Then i relapsed during quarantine but i was eating a lot more calories than my diet phase. I then decided to fully recover, i am now 5 months in to recovery and have overshot my pre diet weight by 20 pounds. I am only 15 but i am eating so much. Do you think i will be able to lose at least some of this overshoot weight and dies age play a role?

  12. I increased from 1000 or below calories up to a goal of at least 1800 and have increased my FT3 by 0.6 points and gained about 17-20 lbs in a three month period. It’s a significant amount on my 5’1 frame but I feel stronger and understand that this is part of a recovery period and will ultimately make me healthier in the long run. So far it’s staying steady but it sure is throwing a wrench in and making it difficult to get on the right amount of levethyroxine!!

    My undereating is not intentional. I grew up with a mother who is smaller than myself and eats like a bird. No one made sure I was eating enough as a young person and those habits were carried into adulthood. Since I’ve always been ballerina thin I was praised rather than being lectured by Drs or nurses to eat more.

    Developing hypo on top of that led to the removal of half my thyroid and then later a full replacement dose, which led to a severely low appetite. I have to log calories daily to make sure I’m getting at least 1800 calories. The absence of an appetite is quite a handicap. No one ever talks about how thyroid removal affects appetite.

  13. I was always thin. I had an eating disorders from 15years old into my twenties. I joined the army at 20 and once I hit 25 started gaining weight even though I was exercising more than ever. Once I had my kids I was eating maybe once per day. The weight kept coming. I tried all the fad diets and would temporarily lose weight just to gain it back and more. I recently started this fit for life program with a trainer and even tried addipex which I didn’t lose anything on. I was tracking my calories for the fit for life group and I didn’t even hit 1000 calories per day. I tried to eat more but it literally made me sick. Plus working out 6 days/week weight lifting… I still didn’t lose anything. I recently had a concussion and cannot workout right now. I’m the heaviest I’ve ever been. I’m at a loss. My doctor said I can restart addipex in March but it didn’t work the first time. I’m desperate to get my body back to a healthy weight. I know I’ve trashed my metabolism but I don’t know how to fix it.

  14. I think I fall into this I ended up gaining over 50lbs during pregnancy. In which my diet was poor I would only eat fast food and skip meals. My weight went down to 178 after I had my baby. I went into a low calorie deficit to 1400 plus weightlifting. Dropped 30lbs. My weight has stalled at 147-149. I have been having a lot of stomach issues for the past 2 months. Plus my hair falls out so much. It has been 9 months since I started my calorie deficit. I usually ended up loosing 10lbs and I would stop counting and eat whatever. Start counting and loose another 10lbs then eat whatever again. Once I reached 150 I couldn’t loose any weight for 4 months. I went back to counting calories in December and moved my first meal to 11am or even 12. That’s when I started having the stomach issues. I upped my steps to 10k plus weight lifting 4-5 Days, sometimes cardio like the elliptical. My weight just went down to 147 and haven’t lost anymore. Idk what to do or how to fix my metabolism. Not sure if this will take me a while to fix.

    • Hi Jen,

      It can take several years to improve metabolic function and it often requires some weight gain and hormone balance to get there.

  15. Is 1700 calories enough to say I am metabolically damaged? For me I am very very slowly losing weight on this but I don’t know if I will ever reach my goal. My body doesn’t seem to know what reverse dieting is and just wants to pile on the fat. Low muscle mass from restricting doesn’t make me feel better either. I generally feel full throughout the day…usually. Though sometimes I wake up hungry or am hungry in the middle of the night.

  16. Hi Dr.Childs, I’m a 33 year old mom of 5 who has struggled with an eating disorder and bad diets since I was about 18. I’m 5”5 and currently 205lbs. My husband and I are on week 14 of 5 days at the gym and super clean eating. I’ve tried so many different levels of calorie intake and it wasn’t until about a week ago that I realized what’s going on. I also suffer with hypothyroidism, but my levels are managed with synthroid and checked every 3 months.

    I was so excited to jump on the scale at our check in only to see my weight hadnt changed a single pound. I was devastated. I’ve been working so hard. We cut out all processed foods, sugars, we don’t drink. Only whole grains, fruits, veg etc. We took progress photos because I know the scale isn’t always the best. But I was mortified it hasn’t moved at all. Not a single ounce.

    I’m also training for a half marathon so my workouts consist of 5 days a week running and 2 days a week lifting. After so much research, it clicked that my metabolism has been through the wringer and I need to fix it.

    How do I know what my calorie intake should be to do this? I’ve used my BMR to calculate TDEE, (but I know my BMR could be off given the state of my metabolism). For my activity level & BMR, my maintenance calories is 2300. It’s been 4 days of figuring all this out and I’ve been eating 2000. Is this too much? Too little? Will I ruin my running & lifting ? I know it’s hard to answer all the questions but any insight into my situation would be appreciated. I don’t want to keep wasting time doing the wrong thing. I’m okay with the weight gain if it means I can fix this long term and get healthy. Thanks!

    • Hi Nikki,

      Assuming your metabolism isn’t impaired and assuming your hormones are balanced, you can assess your relative metabolic rate by picking a number and then keeping track of your weight and measurements over a 2 week timeframe. If everything remains stable then you’re likely right on target, if you gain weight then you’re above target, and if you lose weight then you’ve undershot.

      If your hormones are imbalanced or you have metabolic damage, then those will need to be addressed first.
