Calories 與 Fat Calories 有什麼分別?

Calories 包括蛋白質、 碳水化合物、 脂肪所佔的卡路里總量
1g蛋白質、 碳水化合物是4kcal，1g脂肪是9kcal。

Fat Calories 分別在於是 脂肪所佔的卡路里總量，包括 飽和脂肪，不飽和脂肪等等。

不過Calories 與 Fat Calories 如果都是300kcal，其實身體所吸收的都差不多，兩種卡路里都只要不要吸收太多，即是適度的進食，對一個在瘦身中的人士就不會有甚麼壞影響。

calories is the amount of energy dervied from the food we consumed. fat calories is the amount of calories that comes from fat. in our diet, there contains fats in the food such as saturated fat, trans fat, monosaturated fat etc. when we consumed food, we cannot avoid consuming certain amount of food. such fat contains energy too, hence bringing about the calories coming from this fats. other form of energy that we can derived besides from fats are like carbohydrate (rice, noodle, pasta, bread), sugar, etc. when we purchase a food item, take a look at the nutrition label. it will usually write the total calories per serving which is the amount of energy we will get from one serving of that food (for example 100 kcal). then the label will also indicate that the food of which contains 20 kcal of fat calories. this means that of the 100 kcal of energy per serving, 20 kcal comes from fats.

to loss weight, one should reduce the consumption of fats. however, our body needs fats too (such as oil). i think it is more appropriate to identify the different types of fats in the food. avoid food with trans fats as those fat is very unhealthy and can even cause heart illnesses.

eat everything in moderation and exercise regularly should be the correct way to loss weight. excessive dieting will damage one's health and immune system.
