Tried it. Didn't work for me in the way he describes. The thing is, Martin Berkhan is young, tall and has always been a thin and lean guy. He's never experienced the amount of weight gain that the average person has. He's also a powerlifter and works his ass off in the gym. The problem with the way intermittent fasting is preached is that you can eat pretty much whatever you want within your 8-hour feeding window and still lose fat. Personally, I did not find that to be the case at all, and so I found the results to fall short of what he claimed.
Then we disagree. I won't pretend to know what he's on, but I'd bet my lunch money that he's not natural. https://www.instagram.com/martinberkhan/p/BMmQ4mDjlZ0/
baron, the way you look and eat right now you will never die. you are somewhere around 15% BF, what survival advantage do you see in reducing your fat mass by half, going under 9%??
I agree. Some folks will be gentically predisposed to develop insulin resistance and leptin resistance more readily than others. Nearly every case of overweight/obesity is due to intolerance to processed carbohydrate. There are obviously cases where that is not the case, e.g. lipodema. But most beer bellies and thunder thighs are the result of bread, cakes, and pies. We used to know this not too long ago. Then the government got into the nutrition business and it was all over.
First of all, I didn't undertake this for a survival advantage. I did this to see if I could become the person required to conquer the challenge of it. But considering that toxins and pollutants like pesticides are stored inside of fat cells, then reducing the number of fat cells through diet and exercise will release a lot of that toxic junk out of your fat cells and give your body a chance to sweat it out or excrete it out via urine or feces. So from a survival standpoint, I would think it's a smart choice to reduce as much stored pollutants and chemicals as you can if you want to avoid the diseases associated with storing high levels of these toxins in your system over time.
