How much weight would a 200-poun adult need to lose in a month to be considered significant?

A weight loss of 5-10% of body weight is often considered significant, which would be 10-20 pounds for a 200-pound adult. Losing this amount in a month is typically seen as a healthy and sustainable goal. However, individual circumstances can vary, and it's important to approach weight loss with a focus on overall health and well-being. Consulting a healthcare professional is recommended for personalized advice.
