Ketogenic diets have been shown to be an effective tool to fight obesity with reported good adherence due to their ability to suppress the drive to eat. They are also gaining popularity in public, despite some concerns regarding the quality and timeline of changes of body composition and the effects on health parameters of whole organism.
For effective weight loss, energy deficit is required. Very low energy (600 - 800 kcal) ketogenic diets have been extensively studied.
The proposed study combines low energy (800 - 1500 kcal) and ketogenic diet intervention. The aim of the study is a comprehensive determination of quality of body mass loss, metabolic states changes, physical and psychological performance changes, and inflammatory and hormones profile changes during and post a 12-week low energy ketogenic diet intervention.
