Low-fat and low-calorie foods are mainly various vegetables and fruits. This includes a variety of green leafy vegetables and vegetables containing less starch, such as spinach, leeks, chrysanthemums, celery, bok choy, cucumbers, winter squash, loofahs, eggplants, and tomatoes. Most fruits such as oranges, grapefruit, lemons, apples, bananas, peaches, and pears. The fat and calories in these foods are relatively low. However, it should be noted that apart from the food itself, the way it is cooked will also have an effect on the calorie and fat content of the food when it is ingested. For example, deep-frying, cooking and stir-frying methods will have a significant increase in fat and calories. Steaming and boiling, on the other hand, will maintain the original level of calories and fat.
