Losing 50 lb in two months means losing about 6.25 lb per week, meaning you will have to burn over 2500 calories on top of what you consume every day. This is unrealistic. A safer calorie deficit of 500-1000 calories should lead to steady weight loss.

The Centers for Disease Control and Prevention recommends a gradual, steady, sustainable, and realistic weight loss of 1 to 2 pounds a week (10). So, is it possible to lose 50 lbs in 6 months? Yes. Assuming there are 25 weeks in half a year, you can lose between 25-50 pounds healthily.
