Losing weight is a revolution in a woman's life. If you only take it temporarily and have no firm determination, it is actually better not to lose weight, because it will not be entangled repeatedly. If you really care about this, start with diet, take a little exercise and play badminton.
The reason why you make excuses is because you lack motivation, why you lack motivation, because you are impatient and lazy. In this case, it is more reliable to find personal supervision or find a like-minded comrade. Everyone can encourage and transmit positive energy.
