Proper diet plus exercise is the healthiest way. Generally speaking, it is reasonable to lose 0.5~ 1.5 kg a week. What you lose quickly is just water and protein, not fat, which will make you gain weight seriously.

Also, there is a bottleneck in weight loss, that is, there is a stage, how to exercise, eat less, and lose weight, which may last for a month, and the specific time varies from person to person. You must not give up at this time. This is a critical period. Stick to it and you will lose weight.

You must have weighing scale at home, so you can remind yourself at any time. Be sure to have a weight loss plan.
