How Long Will Weight Loss Take?

For many adults, a realistic pace of weight loss is about 1 to 2 pounds per week. That means the answer usually depends on how much weight you want to lose, how consistently you maintain a calorie deficit, and how your body responds over time.

Some people lose weight faster at the beginning, especially from a higher starting weight, while others lose more gradually. In most cases, steady progress is more realistic than dramatic short-term changes.
