I've lost weight like this, almost 10 kg.

Eat enough every morning.

Eat vegetables at noon

Don't eat at night

You can eat an apple when you are hungry in the afternoon.

Nothing else ~

Get up early in the morning and jump rope outside.

Skipping rope to lose weight.

Climb the stairs in the afternoon

Climbing up and down is particularly effective.

After a week, you will lose weight to your satisfaction.
