The war on Endomorphs has to end

Why “eat less and exercise more” isn’t the answer?

In the last 20 years, obesity went from 30.5% to 41.9% in the United States¹. The usual suspects are fast food chains, sedentary lifestyle, and the lack of willpower. Your advice to your overweight friend is usually something along these lines:

“Eat less, exercise more, and have some bloody willpower to persist; loser!”.

I don’t think it is that simple. This one-size-fits-all advise isn’t fixing anything. I do not think willpower is to be blamed here, and fast food chains, though unhealthy, cannot be the only scapegoat we sacrifice all the time to our dietary gods.

I’ve been struggling to lose weight most of my life, yet, I cannot see that my eating habits are that much worse than everyone else. I am sure you too has the following questions sometimes.

Why does she ever gain wait though she eats sweets all the time? Why can he build muscles so easily, though we are gym-mates? Why don’t they exercise as much as I do, yet they can run for miles without getting tired?

It took me a while to find the answers to these questions.

Our bodies are different, duh!

I went to a dietitian called Farouk Shaheen, 20 years ago. He used to give me different diet plans each weeks, and I kept on consistently losing weight. Then one week, the diet was a bit more restricted, but it included a piece of chocolate during breakfast one day, and a fruit the other day. That week I gained weight instead. He then told me that he wanted to find out that sweets are my nemesis.

More than a decade later, I noticed that ketogenic diet works fine for me. It made me feel less hungry and lose weight easily. It's only problem is that it wasn’t very practical. More on that in “The war on Endomorphs” section below.

Recently, Phil Catudal’s book, “Just Your Type”, helped me connect the dots. Our bodies fall into three broad types, ectomorphs, mesomorphs and endomorphs. Often, one can be a mixture of two types. But the main idea is that each type reacts differently to different food macronutrients and workout routines.
