You can lose about 5 pounds a week without rebounding. Get up in the morning with a cup of tea, then a cup of milk, an egg and a loaf of bread.
Before lunch.
Drink a glass of water first, eat some light dishes, and eat 8 points.
Sleep at night.
Eat for the first 3 hours, drink a glass of water before meals and eat for 5 minutes.
You can lose about 5 to 8 pounds a week, and you will never rebound.
I wish you early success.
