Health at Every Size (HAES) is a weight-neutral approach to health. Other indicators than weight, such as blood glucose, etc., are used to measure a person's health. Some people who live a HAES lifestyle may lose weight, some may stay the same weight, and others may gain weight. HAES promotes that people of all sizes can achieve their best health for their genetics and life circumstances by focusing on healthy lifestyle behaviors like balanced eating, regular moderate exercise, and positive social support - not the number on the scale.
