First of all, the calorie density of high-fat foods is relatively high. Simply put, it is small in size and large in heat. There is no doubt that you should limit your calorie intake when you lose weight. However, in order to be conducive to persistence, while limiting calorie intake, we should also create enough satiety as much as possible, so we should try to eat foods with low calorie density.
Foods with low calorie density are large in size and low in calories. We eat a lot, but it is not easy to exceed the calories we consume. On the other hand, eating a little calories may be too much for high-fat things, but people will still be hungry because they eat too little food.
Second, the efficiency of transforming food fat into body fat is the highest among all macro nutrients. We eat protein, carbohydrates and fat. As long as you eat too much, the intake will exceed the consumption, and the excess may be converted into fat and stored in the body. But the storage efficiency of these three things is different.
The lowest efficiency is protein, which wastes a lot of heat in the process of transforming into fat. Followed by carbohydrates. Most of the fat in our food is basically the same as body fat (body fat is actually triglyceride in fat cells), so food fat is stored as body fat and only needs to consume a very small amount of calories.
In this way, we eat 1 0,000 calories of protein, 1 0,000 calories of carbohydrates and 1 0,000 calories of fat, which looks similar, but considering the conversion rate, we only eat hundreds of calories of protein or carbohydrates.
Not to mention, the body has the ability to regulate protein and carbohydrate balance, but it has no ability to regulate fat. The first two eat more oxidation, carbohydrate and glycogen storage buffer, and no fat at all. Our evolutionary design is to store as little fat as possible in food to cope with food shortage.
Third, in order to ensure that the calories do not exceed the standard, if you eat high-fat food, your food intake will be much smaller, which will easily lead to a decrease in the intake of various nutrients, which is unhealthy.
Fourth, the high-fat diet itself may change our physiological and biochemical environment, even the intestinal environment, making us more likely to get fat. For example, some studies believe that a high-fat diet will affect the normal activities of intestinal flora, leading to disorder of intestinal flora and the emergence of so-called obese flora.
Therefore, the best diet structure for reducing fat is a balanced and diversified low-fat diet. In the final analysis, losing weight is still a matter of calories, but considering comprehensively, controlling calories under the structure of low-fat diet is always the best choice.
