The recommended energy restriction for extreme weight loss methods is typically set at 30 kcal/kg of fat-free mass (FFM). This level of caloric intake is aimed to provide a balance between rapid weight loss and the preservation of lean body mass. Extreme weight loss methods often focus on reducing caloric intake significantly without compromising essential nutritional needs.

At 30 kcal/kg FFM, the energy restriction is substantial enough to induce weight loss, while still allowing for sufficient caloric intake to support metabolic functions and minimize muscle breakdown. This approach helps to ensure that the weight loss is more focused on fat rather than lean mass, which is crucial for long-term health and maintaining metabolic rate.

Lower options, such as 25 kcal/kg FFM, may lead to an excessive caloric deficit, risking muscle loss and nutritional deficiencies. Higher recommendations, like 35 or 40 kcal/kg FFM, would not typically be characterized as extreme energy restrictions, as they allow for a higher caloric intake that may not provide the same level of weight loss effectiveness in a short period. Therefore, 30 kcal/kg FFM is considered a prudent balance for extreme weight loss protocols.
