Yes Ice cream: A recent study in Sweden found that women who eat at least one full-fat dairy product every day gain less weight than women who don't. Although the researchers haven't completely confirmed this connection, they think that linoleic acid contained in milk helps to lose weight. Eating a little cheese, ice cream or a glass of milk every day is actually the best choice, and the vitamin D contained in it can also play an anti-cancer role. Whether you are losing weight or not, you should make dairy products a part of your diet. But don't eat too much. Anyway, full-fat foods do contain saturated fat. It's best to eat only two servings a day. If you want to eat again, choose a low-fat one. The first thing in an ice cream diet is to control your calorie budget. If you can do it, you can enjoy ice cream without guilt. You must control your daily calorie intake within 1200 calories (60-80g is appropriate), including your favorite ice cream, so as to achieve the effect of losing weight. Moreover, although ice cream has a lot of calories, there are not many nutrients, which will reduce appetite after eating sweets. There used to be a star who used to eat ice cream all day to lose weight, which was not healthy and not recommended.
