Not all fish can lose weight, but many dieters are afraid to eat fish for fear of getting fat. This is not right. Fish has a high nutritional value, and eating fish often contributes to memory and brain development. Some fish will not cause obesity when cooked in water. Let's take a look at what fish can lose weight. The fry of a river have a high salt content. Dried fish such as river fish do have calcium, but housewives mostly use it to make soup. After boiling the soup, the soup ingredients (including river fish larvae) are usually dumped. Most people think that all the nutrients are already in the soup, but they are not. To absorb calcium from river fish larvae, you must eat the whole (including bones). Nevertheless, river fish larvae are always high-salt food, so it is recommended to soak them in clear water and wash them before cooking. (Note: Try to avoid taking calcium from a single food, and take multiple foods at the same time to ensure that other nutrients are absorbed at the same time). Two boiled fish can lose weight. Everyone knows that steamed fish is the best way to cook, especially fresh fish. The heat of steamed fish is generally the lowest, because most processes only add seasoning and no oil. ② A steamed white pomfret (100g) not only provides rich protein, but also has only 67 calories (about 3g fat). If the cooking method of the same white pomfret is changed from steaming to frying, the heat will increase to 100 calories (and the fat content will also increase to 6 grams). What fish can't be eaten? ① Sweet and sour fish fillets, which often appear on vegetable rice stalls, are considered as a "healthy" choice by some people. If you choose two meats and one dish when buying food and rice, and one of them is sweet and sour fish slices, then you can easily eat 280 calories,14g of fat (not counting the calories of other foods). ② The curry fish head (100g) that everyone likes to eat has 105 calories (7g fat). When diners eat curry fish head, most of them will add a spoonful of sauce to the rice and enjoy it. It is easy to eat a lot of oil and sodium. Although curry fish head tastes attractive, you should eat it in moderation and don't bet your health. Parents are often seen buying fish and chips for their children. Each plate of fish and chips has 850 calories and 47 grams of fat (about 9 teaspoons of oil). Surprisingly, a primary school student can finish one serving of fish and chips. Parents are advised to instill the concept of healthy eating into their children in time, not to say that they can't eat, but to strictly control the frequency and quantity of eating. First of all, the types of fish are different, and secondly, the cooking methods are different. To lose weight, you only need to boil fish with low sodium and calories.
