Elements of weight control

1, the golden principle of weight control is to maintain a certain negative energy balance.

If the daily intake of energy exceeds the consumption of energy, this is a positive energy balance, and the excess energy is stored in the body in the form of fat. Energy consumption exceeds energy intake every day, which is a negative energy balance. Energy consumption is insufficient, which is balanced by burning fat stored in the body and losing weight.

2. The best way to control weight: aerobic exercise combined with scientific food selection.

Exercise should be mainly aerobic exercise for a long time, and the intensity should not be too high, because the best state of fat burning is moderate and low intensity exercise, and the time must be more than 30 minutes, preferably more than 1 hour, because fat burning in the body will reach the maximum after 30 minutes of exercise.

3. Only fat, protein and carbohydrates can provide energy.

Therefore, when choosing food reasonably, we must pay attention to controlling the energy in food. Among them, protein guarantees a glass of milk, an egg and 1-2 animal muscles every day; Staple foods such as rice or noodles are rich in carbohydrates, and each meal is guaranteed to be 1-2 small bowls of rice; 20 grams of fat intake can meet the health needs.
