What is healthy weight loss? It's natural for anyone trying to lose weight to want to lose it very quickly. But evidence shows that people who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off. Healthy weight loss isn't just about a diet or program. It's about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.
How much weight you lose per week will depend on a few factors. Healthy weight loss is about 1-3 per week. However, how big your deficit is will determine how much weight will come off per week. To lose that 1 pound per week you are looking at having a 500 calorie deficit each week.ny weight loss is better than none. There are 3,500 calories in a pound. To lose one pound a week, you would have to eat 500 fewer calories a day. Life often gets in the way of weight loss.
