What is it about?
In this study, we investigated if there are changes in muscle utilization of energy to maintain exercises that are similar in intensity to "daily activities", such walk to and from work, cook, moving around at work, etc., after overfeeding with 5 different diets or fasting for 24-h each.

Why is it important?
Obesity is the result of increased intake when compared to energy expenditure. However, the degree of weight gain while overfeeding is different among individuals and dependent of the composition of the diet. Because energy expenditure only increase by an average of 10% after overfeeding with doubled of the intake necessary to maintain body weight, leaving the other 90% of excess energy to be or either stored, or utilized somewhere else in order to avoid weight gain, it is important to understand other mechanism that may play a role in the susceptibility to dissipate more or less energy over time.
Perspectives
This study shows how individuals who are overweight and have obesity have different response in muscle efficiency after a 24-h low-protein overfeeding diet, while maintaining similar responses to other overfeeding diets.
