I’m Hormonal: The Key to Weight Loss

We’ve all been told in order to lose weight you need to burn more calories than you eat.  Once you achieve a deficit of 3500 calories you will lose one pound of fat.  I used to believe this as well.  But like many things the full equation is infinitely more complex.  

Ok, let’s do a little math, I promise it’ll be easy.  Let’s pretend you cut your calories by 500/day.  In a week you would have a 3500-calorie deficit  (equal to 1 lb of fat).  In a year it would be 52lbs of the scale.   In a few years, you would simply disappear.  Right?  Now let’s imagine the opposite, add one medium apple (100 calories) to your diet per day for a year (everything else remains the same) you would gain 10lbs (700 extra calories per week x 52 equals 36,500 extra calories).  Does that make sense?  And if you take it a decade down the line you’d gain a portly 100lbs.   On the surface, most of us believe that the only way to obesity is to take in more calories than we expend.

Thought Experiment:

Picture you have an identical twin; you eat junk food all day long and she eats the same amount of calories worth of healthy low sugar foods – otherwise, your lives are equal.  After two months do you think your bodies will look the same?  Skin, hair, muscles, body fat, body weight etc?  Even though you share the exact genetics of your sibling you would express (or turn off) certain genes due to the food you ate and this would affect your body in lots of different ways.  

Calories in and out certainly contribute to weight gain/loss but there are many underlying causes for this, mainly hormones.  Insulin, leptin, ghrelin, T3, T4, and cortisol are the main culprits responsible for regulating calorie intake, body-fat, metabolism and body weight.   These hormones and others make you hungry, sated, fat, skinny, tired etc.  Controlling them is the key to regulating your body fat and changing your physique. Unfortunately, science does not fully understand the interactions and processes of these hormones.   Here is a little of what is known in relation to weight gain/loss:

  • Insulin-  Sugar intake raises insulin which then directs your body to make and store fat. Exercise lowers insulin.
  • Leptin- An increase in leptin causes you to feel sated (consuming dietary fat triggers an increase), while decreases of leptin escalate your appetite (consuming simple carbohydrates will decrease leptin).
  • Ghrelin- This hormone stimulates hunger and the storage of fat in the abdominal region.  Low-calorie diets provoke overproduction of ghrelin!  High protein breakfasts seem to inhibit it.
  • T3/T4 – Higher levels increase your metabolic and fat burning rate (controlled by thyroid). Resistance training boost T3/T4 and low-calorie diets decrease it.
  • Cortisol- When this “stress hormone” is released your body will store fat more readily.  Vegetables, healthy fats and low sugar fruits have been shown to depress cortisol.  Meditation and exercise are also inhibitors of cortisol. 

 

 

Fun Fact:  

Learning may be best when the stomach is empty and ghrelin levels are highest.

Everything we put into and on our mouths affects our hormones.  All calories are not equal. Some calories will raise or lower certain hormones which in turn will make you fat, skinny, hungry, sated, happy, sad etc.
