How Hormones Can Make You Fat?

Do you carry excess weight and never seem to lose it no matter what you do? Would you like to know why this might be and how you can do things differently?

 
There are highly complex interactions chemically and hormonally that can affect our weight. Although it is very complex overall, there are five key players that I will concentrate on in this post, because when you  have an understanding about these players, it will really help you to be as healthy as you can and lose weight.  
 
We are talking about:
  • Leptin
  • Insulin
  • Ghrelin
  • Thyroid Hormones (T3 and T4)
  • Cortisol

Leptin

Coming from the Greek 'leptos' meaning thin, Leptin reduces appetite and increases your metabolic rate. Leptin is produced by fat cells so it stands to reason that people who are overweight have high Leptin levels. However, After a few days on a restricted calorie diet Leptin levels naturally fall in response to the fall in total calorie intake. Our metabolic rate also falls subsequently and this means it's not only harder to lose the weight but also easier to put it back on. You see only after a week of dieting, your Leptin levels can fall by 50%!! 
The trouble is that not only does Leptin fall but this drop affects other important hormones that I will talk about later in the post....Thyroid hormones (hormones extremely important to metabolism) respond by falling, and the abdominal fat-storing stress hormone cortisol shoots up!
 

Insulin

Produced by the pancreas in response to abnormally high levels of sugar in the blood (such as when we eat a chocolate bar or anything containing simple sugars), Insulin gives the body a very powerful message:
"Get these sugar levels down as fast as you can by storing them as fat"!
So ANYTIME you have eaten simple sugars and your blood sugar levels are raised above the acceptably healthy range, you are asking your body to deposit fat. 
 

What is Ghrelin?

Ghrelin is a hormone released by your digestive tract that regulates your levels of satiety. When you miss meals Ghrelin levels increase and make you want to eat more. This is why eating small and frequent meals is a very effective adjunct to a weight loss and healthy eating plan because this helps keep your Ghrelin levels steady and therefore keep you feeling satisfied. Excess Ghrelin has the effect of slowing your metabolism so the saying that excess weight causes excess hunger is absolutely true in this case!
 

Thyroid Hormones

If your thyroid gland is under functioning this means you have lower levels of the thyroid hormones T4/T3. These hormones regulate your metabolic rate and as such a lack of them means a slow down in metabolic rate. This is turn means fewer calories are required and weight gain is almost inevitable. Thyroid hormones interact with Ghrelin and other chemicals that tell us when we are full, so if your thyroid hormones are inadequate your Ghrelin levels will be out of balance and you will want to eat more. In addition, thyroid hormones are important for Leptin levels, because when T4/T3 is present in insufficient levels the effectiveness of Leptin is reduced. 
 
In addition, it is understood that Thyroid hormones help chemical transmitters in the brain function effectively. Some of these chemicals are involved in regulation of satiety, taste and food choice. If your thyroid hormones are out of wack, the levels of these brain chemicals change and so does your food behaviour. As Ridha Arem says in his informative book "The Thyroid Solution" to which I am indebted for information, " thyroid hormones also have direct effects on the appetite centres in the brain" (p123).
 
If you have unexplained weight gain as well as fatigue, it may be wise to see your doctor to get your thyroid levels checked. In this case ask for your TSH, T4, T3, reverse T3 and thyroid antibodies. 
 

Cortisol

Cortisol is produced by the adrenal glands. See more info on these important glands here. Stress can cause high levels of Cortisol to be present and when this happens more visceral abdominal fat is stored. Some people have a greater Cortisol response than others to the same stressors and may be more sensitive to the effects of their own Cortisol. So relaxation is key for weight loss!
 
So what are the Key steps for a healthy eating plan for weight loss? The mainstay of any effective weight loss is that it is slow and part of a permanent healthy eating plan.

 

Here are my top 10 healthy weight loss tips:

 
  1. Relax: Make sure you have a regular activity that promotes relaxation in your day/week. This may be exercise, meditation, yoga or Tai Chi.
  2. Exercise 4-5 days a week
  3. Eat frequent and small meals with a protein source in each one.
  4. Choose complex carbohydrates instead of simple carbs to keep insulin levels low
  5. Never ever eat hydrogenated fats
  6. Avoid saturated fats from animal sources and get your good fats from sources such as avocado and flax seeds.
  7. Add an Omega 3 supplement into your diet
  8. Drink 8 glasses of water a day and eliminate all other calorie laden drinks
  9. Get sufficient sleep to help maintain your Leptin levels
  10. One day a week have a cheat day and eat some foods containing high carbs and fat to trick your body into raising your Leptin levels again.
Happy Health and Homeopathic Prescribing!
