It also consumes energy when walking fast.

It's just that you consume less energy in a day than you do in a brisk walk.

This is equivalent to your daily energy consumption.

For example, you burn 4000 calories in exercise every day.

But your daily energy intake is 5000 calories.

It is equivalent to your daily intake of 1000 calories.

Without energy, consumption will not decrease.

So it is very important to control energy intake.

For example, you eat less every day.

Exercise more.

So there will be energy consumption.

However, this is a long process.

The important thing is persistence.
