Starving is not good for your thyroid.

Updated: Nov 5, 2019

Starving yourself will down-regulate all things related to your thyroid. (M-E-T-A-B-O-L-I-S-M)


At least once a week I receive a text from someone eating around 1000 calories because someone told them or they used an online calculator that prescribed macros for them. They usually follow-up by saying that they dont have energy and that they lost a ton of weight the first couple of weeks but then gained it back.


“If you knew how hard and how long it takes to reverse out of extreme deficits, you would be eating way more. A ton more. “


Your thyroid gland controls everything most people care about: looking good and performing at elite intensities (just like they see on the black mirrors). Your thyroid takes care of your metabolic rate, insulin sensitivity, fat storage, appetite, temperature, cardiovascular function and energy levels.


It’s actually very simple, your thyroid will slow down your metabolic rate to preserve energy every time you severely under feed it, and all the bodily functions performed via your thyroid will suck too.



Think you might be experiencing thyroid dysfunction?

-Your weight changes constantly and you cant lose fat.

-You dont poop often

-You wake up restless

-You have dry skin

-You feel fatigued

-You get cold super quickly

-You have crazy mood swings

-You have low energy levels

-You are never hungry.


A couple of ways to help your thyroid:

✔️8+ hours of sleep

✔️Track a week of what your diet looks like. Make sure you have optimal levels of Iron, Zinc, Magnesium and Selenium. If they are low, consider taking supps.

✔️Eat like a human. Get your calories up to maintenance

✔️Lower stress levels. Minimize the amount of sympathetic stress and add restorative practices like yoga and meditation

✔️Ashwagandha and L-theanine tend to work really well to stimulate a parasympathetic state

✔️Eat plenty of high nutrient foods and drinks lots of water.





Anything close to a 40-50% deficit is an extreme deficit (in my opinion). You want to slowly pull away from that number.

This is how:


The main idea is to slowly add more calories to your diet until you get to your maintenance caloric intake. That would be adding anything between 200-500 calories every 3-6 weeks, depending on how your body is adapting.


The longer you spent in that deficit, the harder it is going to be for your metabolism to adapt to more calories.


You want to make sure you keep track of as many variables as you can, like:

-Is your body weight changing?

-Is your body composition changing

-How are your energy levels? Are they going up?

-Are your sleeping patterns better?
