Question: what percentage of body weight can you lose in a month?
Answer: A good rule of thumb is to aim to lose 1–2 pounds per week or 4–8 pounds per month, says Dr. Elizabeth Lowden, a bariatric endocrinologist at Northwestern Medicine Metabolic Health and Surgical Weight Loss Center at Delnor Hospital in Chicago. In other words, that's about 5–10% of your body weight.
