Hello! Thanks for sharing with us your concern.
The point is that even if they reduce wait you will regain it later. It is more a lifestyle thing than a momental thing.
You need to eat regularly in moderate amounts. Include more protein in your eating susch as fish, chicken, egg, white egg, cheese, cottage cheese, milk, yogurt, more fruits and vegetables and less carnbohydrates such as pasta, white bread and rice, cookies.
Exercise. Do weight training because it build up muscle and the more muscle you have the more calorie you will burn.
Thank you and best regards.
