Carbon day-carbohydrate intake is generally 20-50% of total calorie intake, usually 2-4g per kilogram of body weight.
Low (zero) carbon days-carbohydrate intake is generally 0-20% of total calorie intake, usually 0-2g per kilogram of body weight.
Fast muscle gain requires carbohydrates, but at the expense of increasing fat. Then at this time, some people claimed that if we can adopt a diet with carbon water cycle, we can get the benefits of carbon water cycle to help gain muscle, while avoiding the shortcomings of carbon water cycle to accumulate fat.
Theoretically, if you eat a lot of carbohydrates on high-intensity training days, moderate carbohydrates on medium-intensity training days, and a small amount of carbohydrates on non-training days, you can gain muscle without gaining weight, or you can lose fat and gain muscle.
Extended information carbon water cycle diet, from the core, is also a diet that restricts carbohydrates. Although it may help you lose weight faster, it will not help you lose fat faster.
That is to say, if the traditional 4/4/2 diet requires you to consume 1500g of carbohydrates a week, then the carbon cycle diet may require you to eat less of this. And although the low-carbon diet will be better than the traditional diet in the short term, it is not to reduce fat.
Many people who support a low-carbon or ketogenic diet to lose weight will cite some seemingly powerful studies. However, if you look closely at these studies, you will find something different. One of the biggest problems in these studies is the intake of protein.
In other words, in all the studies showing the advantages of low-carbon diet, protein's intake is a little higher. This is equivalent to comparing a high-protein and low-carbon diet with a low-protein and high-carbon diet. Obviously the former will have an advantage. There is no significant difference between protein and low-carbon and high-carbon diets in weight loss.
