How does a very low calorie diet affect physical activity levels?

A very low-calorie diet significantly restricts the number of calories consumed, which can lead to a decrease in overall energy levels. When caloric intake is insufficient to meet the body's energy needs, the body may not be able to sustain normal levels of physical activity. This reduction in energy availability can negatively impact the ability to complete fitness programs effectively. As a result, individuals may experience fatigue and decreased motivation, which can impede their performance during workouts and lead to an overall reduction in their physical activity levels. Therefore, the impact of a very low-calorie diet is often a decreased capacity to engage fully in fitness activities and routines.
