How is significant weight loss defined within a month?

Significant weight loss is often defined as a loss of 5% or more of an individual's baseline weight within a month. This threshold is adopted by healthcare professionals to indicate a potential change in the person's health status or lifestyle. Losing 5% of body weight can imply changes that may warrant investigation or support, particularly for those who are overweight or have obesity-related health concerns. Such a weight change might be enough to produce health benefits, as it can improve cardiovascular health, metabolic markers, and decrease the risk of chronic diseases.

The other figures, while they may represent notable weight changes, do not fall within the conventional definition typically used in medical and health assessments for significant weight loss in a one-month period.
