For many people, losing weight safely takes time. A common guideline is to aim for about 1 to 2 pounds per week. At that pace, the total time needed depends on how much weight you want to lose and how consistent you are with your eating and activity habits.
Some people lose weight a little faster at the beginning, especially if they start at a higher body weight. Still, gradual progress is often more realistic and easier to maintain long term. For strategies to maximize your rate of loss safely, see our guide on how to lose weight fast.
