A weight loss of 10 to 15 pounds can have a significant impact on health; if you're overweight, it could mean enough weight loss to help improve health indicators, such as blood pressure and cholesterol levels. How long it takes to lose this weight depends largely on your current size and your dedication to achieving the loss. The Centers for Disease Control and Prevention, as well as other health institutions, recommend losing weight at a gradual rate of 1 to 2 pounds per week. At this rate, you'll reach your goal of losing 10 to 15 pounds in just five weeks or up to 15 weeks.
Losing 15 pounds (6.8 kg) in 2 weeks, or 7.5 pounds (3.4 kg) per week, would require creating a daily deficit of about 3,500 calories. To achieve this, you'll need to adopt an extremely low-calorie diet and do a lot of strenuous exercise every day, which is not recommended. Losing 1 to 2 pounds (0.45 to 0.91 kg) per week is considered a healthier rate of weight loss. This requires burning 500 to 1000 more calories than you eat in a day.
