A safe, healthy, and realistic goal is to lose 0.5-to-1% of your body weight per week, which is around 1-to-2 pounds of weight loss per week for most people. In other words, you can expect to lose 12-to-24 pounds in a 3-month period.
That one- to two-pound weight loss per week translates to about 12 to 24 pounds over the span of three months.
Set a realistic timeframe
At one to two pounds per week, losing 25 pounds will take you a little more than 12 weeks, or three months. To lose weight in a healthy manner, you should cut 500 to 1,000 calories a day by eating less and exercising more.
Losing 30 pounds in three months is a lofty goal, but it's achievable if you've got the motivation.
