Fruit is rich in fiber, which is beneficial to lose weight, so many people just eat fruit instead of dinner. Some people simply don't eat staple food, but only eat fruit. The principle of losing weight is really to eat less and sell more, but is it really right to eat like this? Eating less at dinner can really achieve the effect of losing weight, so how to eat at dinner to lose weight? Is eating fruit for dinner useful for losing weight?

1. Can you lose weight by eating fruit for dinner?

1, eating fruit for dinner to lose weight may consume more calories.

Many people think that fruits are rich in cellulose, but almost free of fat and protein. If you use fruit instead of dinner, you can eat it without restraint and kill two birds with one stone.

Nutrition experts point out that from the perspective of nutrition, fruit is not a low-energy food, it contains different calories and sugar. Because it tastes sweet and easy to eat more, the sugar in it will be converted into fat and piled up.

2, especially eating a lot of fruit at dinner, which is more likely to lead to fat accumulation.

For example, every100g strawberry has about 30 kilocalories, and100g litchi can provide about 90 kilocalories. If you can eat a lot at a time, your calorie intake is not low. For another example, in summer, some girls only eat watermelons, but in fact, half a medium-sized watermelon makes you unconsciously consume 680 kilocalories, which is equivalent to about 3 bowls of rice. So just eating fruit and not eating it may be counterproductive.

In fact, some other essential nutrients, such as protein, fat and trace elements such as calcium, iron and zinc, are very few in fruits.

Therefore, long-term consumption of fruits for dinner, whether excessive or insufficient, will lead to insufficient intake of protein and iron, leading to anemia and decreased immune function.

So eating fruit for dinner can't lose weight.

The correct way to lose weight should be a light diet and regular exercise. It's okay to eat fruit meals occasionally, but not every day.

2. The principle of losing weight at dinner

1, it's not too late to eat

Dinner should not be eaten too late, otherwise it is easy to suffer from urethral stones. Many people eat dinner because they work late, and go to bed soon after eating. When people sleep, the blood flow slows down, and urine excretion also decreases, while the calcium salt in the diet is not only absorbed by the human body, but the rest must be excreted through urine.

The peak of urination is usually four to five hours after meals. If dinner is too late, it will delay the peak of urination until midnight or even early morning. At this time, people sleep soundly and often don't get up to urinate, so that high concentration of calcium salt and urine stay in the urethra and combine with uric acid to produce calcium oxalate. When the concentration of calcium oxalate is high, crystals can be precipitated at normal body temperature, which will accumulate and form stones.

2, dinner should not be too full

Chinese medicine believes that "stomach disharmony leads to anxiety". If you eat too much dinner, it will inevitably increase the burden on the gastrointestinal tract, and the information of its intense work will continue to spread to the brain, making people sleepless and dreamy. Over time, it will easily lead to neurasthenia and other diseases. Long-term overeating and repeated stimulation of a large amount of insulin secretion in middle-aged people will often aggravate the burden on insulin B cells, and then lead to failure, thus inducing diabetes. At the same time, if you eat too much dinner, some protein can't digest and absorb it. Under the action of intestinal bacteria, toxic substances will be produced. In addition, intestinal peristalsis slows down during sleep, which relatively prolongs the residence time of these substances in the intestine and may lead to colorectal cancer.

3. Dinner is not meat.

Medical research has found that people who often eat meat for dinner have three or four times higher blood lipids than those who often eat vegetarian food. People with hyperlipidemia and hypertension often eat meat for dinner, which is tantamount to "adding fuel to the fire." Eating meat regularly at dinner will increase the cholesterol content in the body, and too much cholesterol will accumulate on the blood vessel wall, which will induce arteriosclerosis and coronary heart disease in the long run.

4. Dinner is not very sweet

It is not advisable to eat sweets often after meals and dinners. Sugar can be decomposed into fructose and glucose by digestion, which are absorbed by human body and converted into energy and fat respectively. Because people's exercise after dinner is reduced, and exercise can inhibit the conversion of sugar into fat, eating too many sweets at dinner will accumulate fat in the body and make people fat over time.
