Did you know that not eating enough can cause damage to your thyroid?
In the most counterintuitive way possible, undereating can actually make your thyroid worse which will only serve to make your weight loss efforts more difficult in the long run.
This happens because your thyroid is responsible for a huge portion of your metabolism (roughly 50-60%).
And if you lower thyroid function, you will slow down your metabolism in the process.
So if you are someone who wants to lose weight or even maintain your weight then you must pay attention to your thyroid.
The good news is that your body will give you signals if you aren’t eating enough, you just have to know what to look for which is exactly what we are going to talk about right now:
Sign #1. Your weight keeps climbing even after reducing your calories
This is a difficult symptom for many people to understand.
How can you possibly gain weight if you are eating only 1,000 calories per day?
Is that even possible?
It is absolutely possible and it is something that I see all the time.
The amount of calories that you burn each day is largely dependent on something known as your basal metabolic rate.
Your “metabolism” is another name for your basal metabolic rate and this number is responsible for the majority of energy that you burn in the day.
In fact, this number represents around 70% of ALL calories that you burn each day.
Compare this to exercising which may only account for 5-20% of the calories that you burn in a day (depending on how aggressively you exercise).
Just looking at the numbers it’s easy to see why your focus should be on your metabolism and NOT on how much you exercise.
Even if you were able to double the number of calories that you burn with exercise you would only be doubling a small number (a few hundred calories).
If you focus on increasing your basal metabolic rate even 10-20% you will have made a much bigger impact on your energy expenditure and thus your ability to lose weight.
If you are gaining weight despite eating a low-calorie diet then it’s VERY likely that you are suffering from metabolic damage or a damaged metabolism.
The answer to this problem is not to continue to restrict your calories.
Instead, you have to take a systematic approach to slowly increase your calories to improve your basal metabolic rate and reverse hormone damage that may accompany metabolic damage in your body.
Sign #2. You feel cold all of the time
Many people who are not eating enough calories also suffer from changes to their body temperature.
Studies have shown that there is a correlation between the amount of heat that your body produces and the number of calories (4) that you burn in a day (your metabolism).
Your body creates heat by burning energy and that energy is released as heat.
People who have a damaged metabolism often notice that their body temperature is lower than normal.
Instead of a body temperature around 98.6 degrees, they may be 1 to 2 degrees lower than that at rest.
In addition, these patients also suffer from symptoms such as cold hands, cold feed, or cold intolerance.
These people often wear socks to bed and/or they can be found in a sweater in the summer.
This reduction in body temperature is due to a combination of reasons, but certainly, a reduction in thyroid conversion is certainly to blame.
Studies have shown that caloric restriction causes a reduction in peripheral thyroid conversion (5) and an increase in an antithyroid metabolite known as reverse T3.
This increase in reverse T3 helps put on the “brakes” to your metabolism which also causes a reduction in energy production.
Sign #3. You are constantly fatigued
If your body isn’t producing enough energy (outlined above) another symptom will be the subjective sense of having low energy or being fatigued.
The “energy” that your body produces largely occurs in the mitochondria and it is pumped out in a molecule known as ATP or adenosine triphosphate.
It’s helpful to think of your mitochondria as a machine with varying degrees of efficiency.
As you reduce the number of calories that you consume your body will send signals to your mitochondria to reduce the efficiency (6) and production of energy from the cell.
A reduction in even 5-10% of energy production may result in severe symptoms body-wide as your mitochondria slow down energy production.
You can “rev” back up the engine by providing certain cofactors involved in mitochondrial energy production like the B vitamins.
This may explain why people suffering from low energy tend to respond to B vitamins.
Sign #4. Your Hair is falling out
Another indication that you are not eating enough is that your hair is changing (and not for the better).
Hair changes may include any of the following:
- Overt hair loss
- Changes to hair texture or thickness
- Thinning hair
- Receding hairline or male patterned baldness
- Split ends or damaged hair shafts
Hair loss is a known side effect of rapid weight loss.
The hair loss seen with weight loss and calorie restriction is due to a variety of factors.
First:
Hair loss may be exacerbated by nutritional deficiencies (7) such as zinc, iron, selenium, and fatty acids from dieting itself.
Second:
Hair loss may be caused by a reduction in peripheral thyroid hormone conversion (8) and low circulating T3 levels seen in calorie restriction.
Hair loss is a known side effect of hypothyroidism.
Third:
Calorie restriction is a stressful situation that causes changes to cortisol levels in the body.
Stress and changes to cortisol levels (9) are well known to cause hair loss.
If you suffer from hair loss it’s important to realize that this is NOT a normal condition or side effect.
Hair loss can be used as a sensitive marker for hormone imbalance (thyroid dysfunction), metabolic damage, and nutrient deficiencies.
If you suffer from hair loss make sure you are evaluated for all of these conditions and make sure you consider the use of highly targeted supplementation.
Sign #5. You are irritable, depressed, or otherwise not feeling like yourself
When you aren’t eating enough calories you will notice slight and subtle (ok, maybe not so subtle) changes to your mood (10).
People who suffer from metabolic damage notice that they are highly irritable and often depressed.
Studies have also linked depression to changes in appetite, cravings, and food intake.
Why this occurs isn’t completely understood but likely has to do with changes to neurotransmitters from the gut (serotonin), changes to hormones in the body (thyroid), and changes to blood sugar levels.
People who suffer from this condition will notice that their mood changes rapidly once they start eating again.
If you are suffering from mood changes related to food intake then the number of calories you consume may be part of the problem.
Sign #6. You suffer from dizziness or lightheadedness
These symptoms are related to the autonomic nervous system.
This system is primarily mediated by a neurotransmitter known as norepinephrine (or noradrenaline).
This system is under unconscious control and is responsible for adjusting very important systems in your body such as your heart rate, metabolic rate, and control over smooth muscles.
Calorie restriction causes problems with this system (11) which may lead to lower than normal resting heart rate even if you aren’t a conditioned athlete.
It may also cause dysfunction leading to the inability of your heart to adequately respond to exercise.
This may manifest as symptoms such as dizziness, lightheadedness, or the inability to tolerate exercise.
Other symptoms may include feeling dizzy upon standing.
This particular set of symptoms occurs in about 50-60% of patients consuming too few calories.
Sign #7. You are having trouble falling asleep or staying asleep
Lastly, you may notice that you are having issues either falling asleep or staying asleep.
This problem is related to a combination of stress and changes to your circadian rhythm.
Your circadian rhythm is a cycle that helps to regulate processes in your body such as your sleep-wake cycle (12) as well as hormone changes throughout the day.
Humans evolved with these systems in place and even small changes to these cycles may result in big symptoms.
People who suffer from these symptoms often have a “surge” of energy at night making sleep difficult.
They also may notice changes to their heart rate such as heart palpitations that wake them up in the middle of the night or prevent them from falling asleep.
These symptoms indicate an issue with the normal regulatory circadian rhythm.
Healing your Metabolism
If you have 3 or more of the following symptoms listed above then there is a high chance that you are not consuming enough calories.
Knowing you are not eating enough calories is good to know, but it’s more important to make sure that you do something about it.
Most people who are not eating enough calories do so because they notice that it is the only way to maintain their current weight.
They know that if they consume more calories they will likely gain some weight.
And, unfortunately, this may be required in order to get your metabolism back to normal.
Fortunately, this weight will eventually be lost again – but it may take some time.
The worst thing you can do is continue to keep your calories low and cause further damage.
It’s far better to regain a small amount of weight and fix the root of the problem so that you can lose weight long-term later.
#1. Eat enough calories
Part of healing your metabolism will include consuming enough calories to match your existing metabolic rate.
So how do you do this?
Assuming you don’t have hormone imbalances that alter your appetite such as leptin resistance, it’s actually quite easy.
When determining how many calories to consume you want to focus less on your body weight and more on your symptoms.
By symptoms, I am referring to the combination of your energy levels and your appetite.
Your body (again, assuming you don’t have issues with appetite from hormone imbalances) will naturally try to match your appetite to the number of calories that it needs.
If you suffer from metabolic damage you may find that your body only wants 1,200 calories per day and that’s okay to start.
Over time you will notice that your appetite will slowly increase and this is a good thing as it indicates your metabolism is improving.
You will know if you aren’t eating enough because you will have the symptoms listed above and you will also suffer from food cravings.
#2. Eat enough carbs
The next step is to make sure that you are consuming enough carbohydrates.
People under significant stress and those with thyroid issues may need higher than normal carbohydrates for a short period of time.
The reason is that carbohydrates (from healthy sources) help to improve cellular thyroid function and cellular cortisol function.
They also increase energy production (13) which may alleviate the symptoms of fatigue that patients who aren’t eating enough calories often experience.
You need to make sure you get these carbs from healthy sources so if you decide to increase your carbs use these sources:
- Organic fruits
- Starches such as potatoes and sweet potatoes
- Orange juice
- Dates
- Lactose from dairy if you tolerate it
These sources of carbs work best for people with low energy. The amount that you will need to consume depends on the amount of metabolic damage that you have.
The length of treatment also depends on these same factors.
Some temporary weight gain may be seen while increasing carbs, but it will be necessary to heal your metabolism long-term.
Avoid these sources of carbs:
- Bread
- Pastas
- Rice
- Flour
These carbs will result in increased insulin levels which will exacerbate cortisol levels and may cause weight gain.
#3. Take the right supplements
You should consider the use of targeted supplements to help normalize hormonal systems in your body.
Which supplements you use will largely depend on which problems you are suffering from.
Below I’ve included a list of supplements targeted to specific hormonal conditions that tend to accompany metabolic damage:
- Supplements to boost thyroid function.
- Supplements to improve cortisol function and reduce stress.
- Supplements to boost weight loss.
Click on the links for a more in-depth explanation.
#4. Check your hormones
Lastly, you will want to be evaluated for co-existing hormone imbalances.
Depending on the severity of metabolic damage that you are suffering from you may need to be aggressive in your treatment of these imbalances.
The best way to target your treatment is to first identify the presence of these imbalances and then create a treatment plan if necessary.
If you have known metabolic damage (meaning you have damaged your metabolism from eating too few calories) then I recommend you evaluate the following serum hormone levels:
- Leptin (14)
- Insulin (15)
- Cortisol (16)
- Sex hormones such as estrogen, progesterone, and testosterone (17)
- Thyroid function (entire panel) (18)
Treatment will depend on which hormone imbalances you have.
Back to you
The bottom line?
Not eating enough calories may paradoxically contribute to weight loss resistance and make weight loss impossible long term.
This largely has to do with systems that adapt to caloric restriction long term which results in a decrease in basal metabolic rate.
To find out if you are not eating enough calories you can easily assess your symptoms clinically.
If you have 3 or more of the symptoms outlined above then it is likely you are not consuming enough calories.
Treating this problem may result in temporary weight gain, but improving your metabolism will be required for long-term weight loss.
Now it’s your turn:
Are you eating enough calories? Are you suffering from the symptoms listed above?

Hello, Dr.Childs, I’m really happy I found your blog and find it really educational. I’ve been recently diagnosed with Hypothyroidism and am on Thyroxine medication – still considering whether I need to switch to T3 including meds like advised in many of your articles (as you can imagine my doctor won’t be easily convinced). However, this article got me thinking if I am actually starving myself – I am counting strictly my calories… So my question is how do I calculate an estimated BMR so I don’t eat too little?
Hi K1kkz,
As a general rule if you are going hungry each day then you are not eating enough. Testing your metabolic rate is difficult and inaccurate so unless you have an indirect calorimeter you may need to use surrogate markers such as body temperature and resting heart rate.
You decide (against your better judgement) to reduce your calories down to 1,200 per day in hopes that you will gain weight.
Did you mean lose weight in the sentence above?
Hi Dr. Poteet,
Yes, it should read: “You decide (against your better judgement) to reduce your calories down to 1,200 per day in hopes that you will lose weight.”
The typo has been fixed, thanks for bringing it to my attention.
Thanks…personally struggling with this….just had two parathyroid tumors removed…I insisted after watching it for a few years…now I have osteopenia…and apparently thyroid issues…I struggle to keep my weight down…exercise for 1.5 hours a day and have reduced my caloric intake too low…apparently compounding the issue….ugh so frustrated…on 5 (32.5 mg) nature throid now …hoping to increase it….so frustrated in this body of mine…you are a very dedicated Dr. Thanks for helping so many people with all you do.
You are welcome, I hope it helps on your journey!
Do you have any time that I could pay you to have a consultation with me?
Hi Lorrie,
Dr. Childs is currently not accepting new patients.
Sure…I totally understand……I am pretty full right now and am not accepting new patients either…….I do have a waiting list though….if he has one, can you please put me on it? Thanks so much
Take a look at this sentence on your site…it sounds funny and has a typo.: Most people when they switch to armour thyroid except that their extra weight will magically start shedding off… Most people expect that when they switch to armour thyroid, that their extra weight will magically start shedding off…..something like that anyway. Hope you are doing well
Hi Dr. Poteet,
The typo should be fixed now! Thanks for the heads up.
Thanks for the information.
It’s not clear the right amount of calories to consume.
I know that we are different. However, Is there a way to know how many calories to consume depending on the weight, height and age?
Thanks a lot
Hi Rose,
You can get a general idea with certain equations assuming you have no metabolic dysfunction but that isn’t helpful if you have a history of dieting or calorie restriction.
Don’t mean to be spiteful but – come on Dr. Childs – do you REALLY spell potatoes “potato’s”????
Hi June,
Thanks for letting us know, it should now be fixed 🙂
dear dr. Child , i’m a 73 yrs. old woman . I have hypothyroid . my dr. refuse to check my ferritin level because my hemoglobin is ok .now I see another dr. who refuse to check my T3. i’m losing my hair , I cant sleep at night . I would like to try your vitamins but before I do I would like to know if it interacts with warfarin , I have to take it for the rest of my life because I have factor v .please help me I feel like nobody is listening to me . I take 1000 IU of vitamin D by recommendation of dr. my folic acid is low my B12 is 690 . I don’t understand why they don’t want to look any further as far as vitamin deficiency is concern I ‘am so frustrated I could scream at them when I have a visit with them . they think I should take more valium to sleep , and take more antidepressant . another words a band aid solution . I am fed up . Please can you help me . thank you .
I have a damaged metabolism due to very low calorie diets and several HCG diets. Kaiser tested my metabolism rate and found that I was in the low 5% of the population and said that if I ate more than 1050 calories I would gain weight. So I’ve been trying to keep my calories at around 800 per day. I’m going to go on your 60-day metabolism Reset program, I have Hashimoto’s, and my question to you is should I start with 1200 calories a day or the 1500 calories that you suggest as a minimum??? I take synthroid but I’m trying to switch to T3 cytomel because I know my body needs it and it worked for me years ago.
Hi Sandi,
In order to fix your metabolism, you will HAVE to increase your caloric consumption. The best way to do it is to stop counting the calories and match the food that you eat to your appetite. The amount of food that your body tells you to eat is the amount that you should be eating (from a calorie perspective).
Wow! I am so happy that I found this. When I was 29 I started taking Adipex(1 am, 1/2 pm) and maxzide. From April to Sept I lost 30 lbs. Stopped taking it for about 4 months, ate unhealthy foods, gained about 15 lbs back, started the plan again lost it again in a matter of 3-4 months then stayed on it for maintenance for about 5 months. Ate unhealthy again for about 6 mo and Gained everything back. At 31, I tried the plan again, without the diuretic, and for 4 months, haven’t lost a lb. and was severely irritable! Doc changed the prescription to phendimetrazine, still nothing. Now after reading this, I’m worried about thyroid and hormones and don’t know how to find a Dr that will take the time to help me.
Hi Michaelene,
I would be sure to check out this post which can help you find a Doctor to get you on the right track: https://www.restartmed.com/thyroid-doctor/
Hahaha….. Can I eat so little that my body will eventually break all the laws of physics and become so efficient I don’t need any calories at all.
If what you say is true, how do anorexics exist? Why is it so hard to get anorexics to gain weight in recovery? By what you are saying, they should be so efficient in metabolic ‘damage’ that one scoop of ice cream should fatten them back to regular weight. Lol
Hi Jen,
I’m not sure I understand your question. Anorexics do experience exactly what you are saying. They gain weight very easily after eating relatively little which triggers their anorexia in a vicious cycle. And it’s certainly not hard for anorexics to gain weight in recovery, as long as they are eating. What you find is that they are hesitant to eat because they gain so much weight so easily.
Your body has a basic set of functions required for cardiac function and brain activity for which your body will not go lower and that number is probably set around 600-1,000 calories per day (depending on the individual). So even if you are anorexic, you will never be able to get your metabolic rate down to 0 because critical functions require some amount of metabolic energy.
If you don’t believe the information posted here then I would recommend you look further into the 18 research articles listed at the bottom of the post which highlights the physiology involved in this process. Once you read them you will probably have a much better understanding of what I am talking about here.
I certainly can attest to this, I have been anorexic at 19 and bulimic where I would excessively exercise and not eat. I was underweight for about a year and then tried to be “normal” due to social pressures… I gained 30% of my weight in about 4 months time. And losing that was more difficult than the first time….

This is the first article I found with an explanation of why my hands and feet are so cold after losing over 100 pounds taking Phentermine. I have metabolic adaptation syndrome for sure! And the worse part is that I raised my calories from 1200 to 2000-2400 a day for some time now and I am still cold. I have gained 4 pounds too! What am I to do?
Sorry about using kgs, but I live in Australia.
Big problem – I have been on diets my entire life, since I was 12. I’m 46 now & 20 years ago I lost my main weight of 35kgs, since then I’ve had 2 kids & have put 9kgs back on . I really hate feeling fat again.
But no matter what I do, exercise allot, eat keto, eat paleo, eat less than 1200 calories a day etc. The weight simply will not move at all.
I tried eating 2000 calories daily in healthy foods, Having my macros balanced between protein / carbs & fats but just simply couldn’t finish All the food each day & I still managed to gain 1kg in 1 week. Very frustrating.
What can I possibly do to Kickstart my metabolism & get back into the shape I was most comfortable at? I’m 5ft 7in tall & weight 69kgs. My target weight is 60kgs. Thanks
Hello, I have found this article very informative and after reviewing the symptoms this hits close to home. However, I’m still confused how to start the repair. Your advice is to listen to your body, but I’m not hungry. I’m turning 45 in a few months and currently weigh 163. That’s not ideal for a female height of 5’1″. I had thyroid cancer when I 15, fortunately, it was the least aggressive of the four and had to have my thyroid removed and radiation. With no thyroid I rely on medicine, I currently take 125mcg. Last fall my I decided to have my regular Dr. check my level with my physical (thought I would save a copay by not going to my endocrinologist). She changed my dosage down from 137mcg down to 100mcg. I put on 15 lbs within a few months and of course that was around the holidays, but that never happened in the past. When I went to my endo Dr. in Jan she started increasing my levels and plan to have more blood work done this month. Since, I’ve been working from home due to Covid19, I thought this will be a great time for me to lose weight and not be distracted by office parties and morning meetings with doughnuts and bagels. I’ve been eating very healthy and exercising (which isn’t new), but my weight stays the same. What you said about past diets is fascinating, I once did a diet where I ate very clean for a few weeks and lost 13lbs and another 7lbs in the next phase. Years later when I attempted it again – nothing happened, even though I ate the same. Same goes for Weight Watchers, worked for me once, but not anymore. What I am struggling with is how much should I be eating? If I listen to my body, some days I may not eat until 2pm and other days I feel like I want to eat all day.
My wife though her intestinal were shot. Went to walk in for help. They said everything is good . To made a long story short she would not eat enough no appitte. Loss a lot of weight. Ended in hospital they had to put a feed tube in to her stomach to feed her she would not eat. She is now home with feed tube that I have to feed a liquid food four times a day. Her weight went from 105 to 74 At 1500 a day she is not gaining weight. Over 5 months no real Boul movement. I need help. What should I do she 67 years old 5 feet four.
This is, undoubtedly, the most reasonable article I have read on true weight loss. I will try this since I am closing in on pre-diabetes.
This article is definitely me…..Though not intentionally. I KNOW BAD idea to do Keto / Carnivore (( on / off )) over a number of years. Mostly due in part to Candida (( even up to 2 years ago candida was in my Live cell )) ONLY this Past January 2025 NO candida was present.And was under SEVERE stress from November 2022 to April 2024 my mom we believe had covid (( then congestive heart failure she battled a pleural effusion for 1 ( 1/2 ) years (( we almost LOST her and due to covid happening then she wouldn’t go to a doctor or hospital )) she put my older brother and I though HELL. I have had hashimotos thyroiditis since 2008 after a vaccine damage (( almost dying I was CLOSE to death )) and keto / carnivore ….MADE EVERYTHING worse……Thyroid got worse ……PAUL SALADINO MD on Youtube his video on keto and his experience changed my life and your video on thyroid and it needing carbs to function …..BOTH of you got me QUITTING KETO ASAP (( and carnivore too )) ….Plus we had a dog for 13 years VERY difficult dog we inherited from a renter (( she too was very sick with Lyme )) the dog passed December 1, 2024 …..one less STRESSOR to deal with. Since upping my carbs ….sleep improving , muscle strength slowly coming back, fatigue slowly improving…..have 54 POUNDS to lose probably from keto increasing cortisol and worsening thyroid (( DANG ))) but when you have NO doctor who is helping you (( I FIGURED this OUT without my doctor )) 1-2 weeks ago…..My functional doctor said we have to talk about nutrition BUT haven’t gotten there yet. SUPER glad I figured this out first. Slowly feeling improvement. I was getting almost bed bound , taken transit buses MORE , exercise intolerant , felt I would be giving up biking this summer . Thankfully that is coming back. I have been feeling VERY housebound and THAT isn’t me. I KNOW my metabolism is screwed . Extreme DIZZINESS when standing up to 3 years ago my doctor wanted to send me to a neurologist because of that …..but I was outside the hospital region so they didn’t take me……muscle cramping on keto NOTHING helped I was glad to hear Paul Saladino’s experience in this area …..feeling like your falling in bed muscle jerking I HAD while trying to sleep, feeling DRUNK while OUT , couldn’t walk a straight line…..Increasing my intake of food has DRAMATICALLY helped with that. Still there……plus I think I gave myself POTS on keto (( though my naturopathic DR told me I had POTS not how I got it BUT his suggestions NEVER helped )) NO one asked or explained POTS or where I got it…..my diet I believe …….when you get NO insulin spikes you can’t hold on to electrolytes …..and I had a ECG and echo and discovered slight mitral valve prolapse BUT to recheck in 3-5 years . Fainted last May 2024 , by August 2024 had to go on midodrine……ONLY in the last YEAR have I had TIME for myself especially since December 1 , 2024 when our dog died. A TON of her care was on me.
Have started eating WAY more . Feel like I can get up early in the morning still fatigued BUT not feeling so asleep. Have a LONG ways to go. And I am ordering your supplements to help especially T2 and thyroid fat burner . Been on desiccated thyroid 17 years almost and still LOADED with symptoms 17 YEARS. I miss my old self. Anyhow I deeply appreciate your work .
Question here ……having done keto/ carnivore for awhile how long does it take for this slight insulin resistance to wear off . IT is helping my thyroid and helping me be able to exercise more biking (( though I am still fatigued )) plus SLEEP is improving. Getting to bed earlier by 10 PM usually fallen asleep . Before I would be up till 2-3 AM. Plus I am gaining STRENGTH in my arms again , was getting to a point I was unable to lift stuff up our basement stairs without feeling like I would drop it. I KNOW being keto / carnivore screwed my hormones up THYROID DOWN. Plus being on a restricted diet hasn’t done me one bit of good. YES I have learned from this experience . CAN’T WAIT to get the supplements I ordered from you !! After I eat carbs I feel fatigued …..I TRY hard to get out exercising after meals. I am SEEING improvements and I was able to do some sorting and cleaning housework wise . I was close to being bed bound. Just wondering how long this Temporary insulin resistance takes to wear off?? I read it is Temporary from being Keto. Just have no time frame how long it takes to wear off ….probably my thyroid involved to compared to others who don’t have a thyroid problem.
