Carbs enhance how our hormones work.
One hormone that MANY people have issues with is the thyroid gland.
There is “An estimated 20 million Americans have some form of thyroid disease. Up to 60 percent of those with thyroid disease are unaware of their condition.”
Did you know that the thyroid affects nearly every other human cell in the body and every single hormone in the human body.
Which means if you have a thyroid issue, you might have other underlying issues as well. This could be cortisol issues, low testosterone levels, estrogen imbalances, or metabolic adaptation – there could be more that you don’t even realize yet.
One thing many people gravitate towards when it comes to hormones in general, is that fats (lipids – macronutrient) positively impact them. This is very true and it’s a well-known fact that if we have fats below 20% of our daily total caloric intake, we’re likely to start seeing serious hormonal imbalances.
So remember, carbohydrates play an important role in thyroid health,. To have a healthy metabolism, it needs to function properly. Our body produces an important hormone called T3.
T3 is the most active thyroid hormone and is incredibly important for blood glucose management and proper metabolic function.
Low T3 levels can lead to a condition called euthyroid sick syndrome, in which people are constantly cold and sluggish. (This could be your metabolism or “body motor” idling at a slower speed.)
A study, known as the Vermont Study, found that T3 is very sensitive to calorie and carbohydrate intake. When calories and carbs are too low, your T3 levels drop.
Also, the Vermont Study found that another hormone, reverse T3 (rT3), is also sensitive to calorie and carbohydrate intake. Reverse T3, as the name implies, inhibits T3.
Getting enough carbs can lower reverse T3. Not eating enough carbs will increase it….. blocking the important work of T3.
Other research confirms that ketogenic (ultra-low carb) diets reduce T3 levels as rapidly as starvation!
So, when you don’t eat enough, and/or eat enough carbs while training:
T3 goes down
Reverse T3 goes up, further blocking T3
You feel like crap, and eventually your training sucks
If you’re active, you need adequate energy and carb intakes for a healthy thyroid.
Cortisol up; testosterone down
Research consistently shows that people who exercise regularly need to eat enough carbs or their testosterone will fall while their cortisol levels rise. This is a sure-fire recipe for losing muscle and gaining fat.
So inadequate carbohydrate intake can decrease testosterone (which no one wants); and
increase cortisol (which no one wants);and negatively affect your performance hence training. (which no one wants).
