No, your body actually has two sources of energy, one is glycogen and the other is fat. But your daily activities only consume glycogen for energy, and will not directly decompose fat. It is necessary to ensure a good time and heart rate during exercise in order to metabolize fat after a period of time, so squatting can never replace the exercise effect of aerobics.

I suggest you visit more knowledge websites such as Zhihu, Shell, Mint.com, etc. I used to use the food bank in Mint.com to calculate the daily intake, which is quite good, and I can also learn many scientific methods to lose weight from forum posts, such as exercise effect.

Hope with pure hands is a kind of gratitude ~ I wish you lose weight as soon as possible ~
