Why is it important to include fruit in the diet menu?
Despite the abundance of sugar in fruits, there are several reasons why they are very important to include in your diet:
- The low calorie content of most types (below 50 kcal/100 g) allows you to eat several fruits a day without fear of going beyond your daily caloric intake.
- Almost all types of fruits are very rich in retina (only fresh fruits and no preservation), which improves the digestion process, removes toxic substances from the body and helps avoid constipation. As a result, the weight of a losing weight person decreases due to natural reasons.
- Due to the juiciness of many fruits, urination becomes more frequent and swelling decreases, which allows you to lose another 2-3 extra pounds.
- Fruits with complex carbohydrates keep you feeling full for a long time, reducing the risk of overeating.
At the same time, the importance of complex sugars does not at all detract from the advantages of simple ones, which are found in bananas or other fruits that are “harmful” for weight loss. They are just as useful and can saturate the body with energy, but with the only difference – for a shorter period of time.
We conclude with useful ideas - how to eat fruits to lose weight
It is advisable to include fruits, especially those rich in simple carbohydrates, in your morning or afternoon diet. They go well with yoghurts and cereals. Low-calorie oatmeal, cooked in water or skim milk, is perfectly complemented by bananas and peaches. However, the best option is to eat fruits as an independent food in the intervals between main meals. This is an easy way to curb your hunger while snacking to protect yourself from overeating at lunch or dinner. For the evening, fruits with a long-lasting satiating effect, which are full of fiber and contain complex carbohydrates, are suitable. For example, a serving of light fruit salad based on citruses, kiwi and pears with the addition of natural yogurt. An avocado dish is not forbidden for dinner, but you can only eat half of the fruit. Try to always keep a couple of fruits on hand as a substitute for sweets. While enjoying their taste, allow yourself to take your time. It’s better to forget about the concept of “eating on the go” altogether, since it goes against the feeling of fullness. The brain simply will not notice that you are already eating the second banana, because it is busy with other important tasks - filling out a report, hastily walking, etc. And most importantly, is it possible to gain weight if you eat a lot of fruit? Yes, that's why it's important to stick to the daily intake. For a healthy person it is 250-350 g daily; for those who are struggling with extra pounds, the norm is halved. This value applies to all types of fruit, regardless of their calorie content, and this is another reason to eat slowly and truly enjoy eating.

- Fluoride helps remove heavy metals from the body, accelerates the restoration of tissue cells, improves metabolism and strengthens the immune system.
- Vitamin C also strengthens the immune system, and also ensures the normal functioning of the endocrine system, strengthens cartilage and blood vessels, and destroys dangerous molecules - free radicals. Vitamin C also promotes wound healing and reduces the likelihood of developing dangerous pathologies (stroke, heart attack, diabetes).
