Eat 5,800 Calories Daily on an LCHF Diet and See What Happens

When low carb, high fat diet is mentioned, there is always one question frequently asked. What will happen if you stuff yourself and “overeat” while on a LCHF diet?

The answer to this common question gave Sam Feltham with his experiment which lasted three weeks. He started eating huge amounts of food that is based on LCHF diet, which meant about 5794 calories on daily base. If you think about it, all excess calories you eat will turn into the fat, and you would gain weight. But in reality Feltham gained only 3.5lbs (1.7kg) opposite to 16.5lbs (7.5kg) that he should have gained.

How’s that possible? Here is the explanation:

There are few explanations of this phenomenon. The explanation which is most likely true is that his energy expenditure grew intensely while he was doing this experiment.

The other is that his body actually adapted and tried to maintain the appropriate weight and fat mass by decreasing the metabolic rate. The proof for that is also an example of when you are starving a long period of time, you won’t lose as much weight as calorie counting predicts, and it is because the body can adapt to a different conditions.

Hormonal Regulation

All of this above is only applied if you have your body’s hormonal regulation balanced. Bad carbohydrates can harm the hormonal balance, if eating large amount of them.


You’ve probably seen the movie called “Supersize Me”. If you didn’t watch it, then you should. It is a fine example of what happens when you overeat with bad carbohydrates. Morgan Spurlock, star of the “Supersize me” ate about 5,000 calories a day, for one month, and all of those calories originated from McDonalds. The only thing different was that he was on a high carb, high fat diet, so he gained whole 24.5lbs (11.1kg).

The whole point of this story is that you have to make a difference of what you are eating. If you are loading yourself with bad carbohydrates, you will gain weight faster than ever.

But, on the other hand, if you are on LCHF diet, it will be hard to gain weight. You will have to eat too much food, even when you are not hungry, and even that the final result will probably be like Feltham’s.
