You can start from the following aspects when choosing low-fat desserts:

1. Choose low-fat desserts: Low-fat desserts usually use low-fat milk or plant-based dairy products. For example, soy milk, almond milk, etc. can be used instead of whole milk, and low-fat and low-sugar fresh cream or unsweetened yogurt can be used instead of heavy cream.

2. Choose low-sugar desserts: Low-sugar desserts usually use natural sweeteners, such as fruits, honey, etc. instead of white sugar, or use low-sugar ingredients, such as dark chocolate, coconut sugar, etc.

3. Control food intake: No matter whether the dessert is low-fat or low-sugar, excessive consumption will increase the intake of calories and fat. It is recommended to eat it in moderation.

4. Homemade desserts: Homemade desserts can better control the ingredients and calories, choose low-fat and low-sugar ingredients, and make healthier desserts by yourself.

For example, you can choose fruit salad, low-fat yogurt, coconut milk pudding, dark chocolate and other low-fat and low-sugar desserts. However, you still need to choose desserts that suit you based on your preferences and physical condition, and don't overeat.
