American research: Eating breakfast will increase energy consumption and make it easier to burn fat to lose weight! DIT slimming principle When food is eaten from the mouth, the internal organs in the body begin to move. When the gastrointestinal tract digests and absorbs food, various digestive glands begin to secrete, and the liver begins to process and absorb various nutrients. These processes will consume energy and produce heat, especially the liver, which produces the most heat and the highest temperature when the human body is at rest. Dietary induced thermogenesis (DIT), also known as the special dynamic effect of food, refers to the increase of thermogenesis after eating. Body fever after eating in winter and sweating after eating in summer all have the effect of diet inducing heat production. But heat production is not to maintain body temperature, but a by-product of food digestion and absorption. Although people once thought that heat production has little to do with circadian rhythm, heat is essentially a process of energy conversion. The human body absorbs the nutrients in food, or directly uses them, or converts them into glycogen, fat and other standby energy sources, which are stored everywhere in the human body. Energy metabolism will be affected by circadian rhythm, so heat production will also be affected by circadian rhythm.
Burn more calories after breakfast. According to the researchers, 16 young men were recruited to participate in this experiment. The average age of these men is 23.6, and their body mass index is 22.5. They are all healthy and sleep regularly. Generally speaking, the resting metabolic rate of the subjects increased after eating both breakfast and dinner, that is, food-induced thermogenesis appeared, which lasted for 3.5 hours after eating. Moreover, the metabolic rate caused by high-calorie diet increases, which is more obvious. Under the same calorie intake, whether it is a high-calorie diet or a low-calorie diet, breakfast can cause a more obvious increase in metabolic rate than dinner. Especially after eating a low-calorie dinner, food-induced thermogenesis lasted less than 1.5 hours, and then further decreased, resulting in negative thermogenesis. On the whole, with the same calorie intake, breakfast produces 1.5 times more food than dinner to induce heat production. Breakfast is much more than dinner, and the fluctuation of blood sugar and insulin levels is smaller and the peak value is lower.
Eating more for breakfast is healthier than eating more for dinner. According to research, although dinner can reduce hunger and satisfaction more than breakfast, this effect has nothing to do with how many calories you eat. High-calorie diet and low-calorie diet have similar satiety at dinner, but at breakfast, high-calorie diet has a stronger satiety than low-calorie diet, and also reduces the desire for sweets. From this point of view, eating more in the morning can not only increase energy consumption, but also reduce the daily fluctuation of blood sugar and insulin, and reduce hunger and desire for sweets.
