From a practical point of view, if the third combination is used, the time between meals will be too long, and many people will not be able to stand hunger. So few people use this combination diet without lunch. The first combination is to skip breakfast. Many people want to save trouble, because office workers work hard in the morning and get up late, so they can skip breakfast as a way to lose weight. In fact, skipping breakfast is very harmful to the body and is not conducive to losing weight at all, so it should not be used. On the contrary, the plan of changing three meals to two meals that can be considered is more reliable only if you don't eat dinner. Although there are many problems, they can be made up by some dietary arrangements, which will be mentioned later. ?
There are many scientific ways to lose weight by dieting, each of which has its own weight loss theory and basis. ? The original intention of "changing three meals to two meals" is to lose weight by eating less, and its essence should be "reducing calorie intake to lose weight", that is, "negative calorie balance method". Therefore, if three meals are changed to two meals, the total calorie intake will not be reduced, which is meaningless in theory. After taking this measure, another problem is to reduce the number of meals. If the total calories and food intake are indeed greatly reduced, it will trigger the self-protection mechanism of the human body. ?
The human body will receive such a signal: the shortage of food supply reduces energy consumption, so the metabolic level drops. In other words, the body is not prepared to stay at the original level of calorie consumption, and the level of fat burning will also decrease. However, many people do lose weight in a short time, mainly because of the loss of water and nutrition, not the consumption of fat. Of course, you can't keep your calorie intake low forever. Once the previous eating habits are restored, the body will be rapid. ?
This is why people who lose weight by hunger will eventually get fat, and may get fatter. If dieters only reduce the number of meals and the amount of food they eat, it is likely to lead to nutritional imbalance. In addition, the long-term hunger is likely to be automatically compensated after the next meal, and the eater may not realize this or resist the appetite, so he can't help eating. This unhealthy diet is a syndrome of hunger, overeating or overeating, which will stimulate the gastrointestinal system and cause various digestive system diseases. ?
Some people take more radical measures, such as eating only a small amount of breakfast and lunch and not eating anything the rest of the time, which may also lead to malnutrition, anemia and osteoporosis. If the method is correct, it will really help to lose weight. However, many people failed. One of the important reasons is that they only pay attention to eating and indulge in diet control other than eating. The so-called "out-of-meal diet" refers to everything you eat in your stomach, including snacks, cakes, drinks, fruits and so on. ? It is usually unhealthy to eat more than two meals in three meals. ?
However, if dieters can more scientifically design the overall diet plan of changing three meals into two meals, it is still feasible to change three meals into two meals, but it is only recommended to skip dinner instead of breakfast or lunch. Changing three meals to two meals is essentially a kind of diet, but the long-term effect of losing weight through hunger is not ideal, and it also increases the risk of related diseases. This is not a long-term way to lose weight. Diet is a systematic project. Dieters should keep a holistic view, and besides the regular diet, they should also incorporate unconventional diets, such as snacks, cakes, drinks and fruits, into the overall diet plan to control the diet.
