The main goal of nutrition is to eat as healthily as possible, while avoiding refined sugar and carbohydrates. Basically, these empty calories may taste good, but they tend to increase insulin and deliver energy to your fat cells.
In my own weight loss journey, the chief culprit is insulin sensitivity, which I believe is a challenge faced by most people. I mean, how does your body react when you eat food, and whether food will be stored as glycogen-for the next exercise or as fat. Unfortunately, most of us have experienced the challenge of storing fat.
Now, back to the combination of carbohydrates and fats. Let me mention a study. This experiment studied the effects of two diets on weight loss. The study was conducted among hospitalized men and women. One is to separate carbohydrates from fats, and the other is the overall balance of carbohydrates, fats and protein.
Both diets provide the same calorie range and the same number of macros.
After 6 weeks' experiment, people in the balance group lost weight 16.5 pounds on average. Those separated groups (those that separated carbohydrates from fats) lost 13.6 pounds on average.
From this experiment, you can see that people with a balanced diet lose the most weight, but the difference is not so big that it really has a great impact.
It can be seen that the biggest winner in the weight loss war is the reduction of calories, not the combination of food types. However, if it makes it easier for you to plan your diet and stick to it, please stick to it (if you are experiencing weight loss success). But there is really no need to change your food mix, and it doesn't have much impact.
Personally, I find that the most effective way to prevent weight gain and maintain weight loss is to stop eating for a long time, so that your digestive system can rest and force your body to use stored fat to provide energy. This is a way to reduce calories, but it will not slow down metabolism. In fact, this is one of the best ways to bypass these stupid food theories.
So the best result is a balanced diet and proper exercise. Emphasize that carbohydrates and fats in a meal will not be harmful to your results. Quality-oriented, fasting for the best effect.
