According to research, pineapple, honeydew melon, papaya, kiwi fruit, banana, grape and other fruits have high glycemic index, so dieters should avoid taking too many of these fruits. However, apples, kiwis, lemons, plums, cherries, oranges and so on have low glycemic index, which is a better choice for dieters when they match fruit meals.
Secondly, it is best to eat fruit before meals. Studies show that if you eat some fruits or drink 1 2 cups of juice 20 to 40 minutes before meals, you can prevent obesity caused by overeating. Because fruit or juice is rich in fructose and glucose, it can be quickly absorbed by the body, raising blood sugar concentration and reducing appetite. The crude fiber in the fruit can also make the stomach feel full. In addition, eating fruit before meals can significantly reduce the demand for fatty foods, which indirectly prevents the adverse consequences of excessive fat accumulation in the body. However, many fruits, such as persimmon, hawthorn, almond and pineapple, can't be eaten on an empty stomach. In order to lose weight, when eating fruits before meals, it is best to choose fruits that are not too acidic and astringent, such as apples, pears, bananas, grapes, watermelons and melons.
It is difficult to lose weight by eating fruit after meals. Because eating fruit after a meal is equivalent to eating extra sugar, which is easily converted into fat and stored in the body, and may also gain weight. Especially don't eat a lot of fruit after dinner, because synthetic fat is most likely to accumulate in the body after eating at night. However, some fruits can promote digestion, such as pineapple and kiwi fruit rich in protease, lemon and hawthorn rich in organic acids, etc. For such fruits, you can eat them about an hour after meals.
Third, don't eat too much fruit. Most people think that fruits are rich in cellulose, almost free of fat and protein, so they can be eaten without restraint. In fact, this is a misunderstanding. Fruit is not a low-energy food. Because it tastes sweet, it is easy to eat too much, and the sugar in it will be converted into fat and accumulated. For example, there are about 30 calories per100g of strawberries. If you like strawberries and can eat a lot at a time, the calorie intake is amazing. Another example is eating half a medium-sized watermelon (the pulp weighs about 2 kilograms), and you will unconsciously consume 680 calories, which is equivalent to about three bowls of rice. Therefore, when eating fruit diet meals, we should control the consumption of fruit.
Fruit weight loss list
1 apple: it is rich in pectin, which can help intestines combine with toxins, accelerate detoxification and reduce heat absorption. In addition, apples are also rich in potassium, which can prevent leg edema. Chewing the apple with a little hardness slowly and releasing the ingredients not only makes you feel full, but also has low calories.
2 Grapefruit: Grapefruit acidic substances can help increase digestive juice, thereby promoting digestive function, and nutrients are easily absorbed. In addition, why grapefruit will be listed as a must-eat fruit when losing weight? The reason is that it is rich in vitamin C, about one grapefruit has 100 mg, which can not only eliminate fatigue, but also beautify the skin! What's important is that it contains less sugar, so it's the best way to supplement vitamin C by losing weight. As for the heavy sour taste that many people are afraid of, I suggest you drop a little honey on grapefruit and the sour taste will be neutralized immediately!
3 Tomatoes: Strictly speaking, tomatoes should be classified as vegetables. So it is often seen in ingredients. Tomato contains lycopene, dietary fiber and pectin, which can reduce calorie intake and promote gastrointestinal peristalsis. Moreover, the unique sour taste can stimulate the secretion of gastric juice and even improve the taste of food, which is a good healthy ingredient!
4 Pineapple: Have you ever heard people say that pineapples are "beneficial" and must be eaten after meals so as not to hurt your stomach? This statement has a basis! Because the proteolytic enzyme of pineapple is quite strong, although it can help protein digestion of meat, if you eat it before meals, it is easy to cause stomach wall injury! Therefore, we must pay attention to the time problem when eating pineapple to lose weight.
Banana: Banana with sugar as the main component can be digested immediately after eating and quickly replenish physical strength. Moreover, bananas are very full, so you can wrap your stomach by eating one, and the calories are quite low. Don't think that it is not good for losing weight just because it is sweet. (Suggestion: peeling bananas and mashing them into paste can make facial skin tender and refreshing for a long time, which is suitable for facial beauty of dry or sensitive skin with good effect. )
Kiwifruit: Kiwifruit (kiwi) with a lot of vitamin C has always been the favorite of beautiful girls. As for its dietary fiber and rich potassium, it can be included in the list of slimming fruits! Like pineapple, kiwi fruit also contains a lot of proteolytic enzymes, so it is the best match with meat dishes. Kiwi fruit with a little sour and sweet taste has the strange effect of preventing constipation, helping digestion and beautifying skin, but it is still available all year round, which provides a lot of convenience for everyone in the choice of fruit!
7 Lemon: The sour taste of lemon is mainly citric acid, which is an essential substance in the process of promoting heat metabolism, and also has the function of eliminating fatigue. The vitamin C content of lemon is also well known. Girls usually use it to whiten skin, and its function of promoting intestinal peristalsis is often used as an auxiliary diet for people who are losing weight!
