Researchers studied the safety of very low-calorie ketogenic diets (VLCKD) in 106 people with obesity over several months. VLCKD is an extremely restrictive form of the ketogenic diet that combines very low calories with high fat, moderate protein, and minimal carbohydrate intake to promote rapid weight loss through ketosis. While this approach has shown promise for treating obesity, there were concerns about potential side effects since most previous safety studies were done in normal-weight individuals using ketogenic diets for other medical conditions.
The study found that VLCKD was both safe and effective for people with obesity. No serious side effects occurred, and the mild side effects that did happen were temporary and easily managed by healthcare providers or resolved on their own. Only 9 participants (8.5%) stopped the diet early - but this was due to taste preferences or cost concerns, not health problems. Those who experienced side effects lost just as much weight as those who didn't, suggesting that minor side effects don't interfere with the diet's effectiveness.
The results are encouraging for people considering medically supervised ketogenic approaches for significant weight loss. Participants achieved substantial weight loss (13-18% of body weight on average) while maintaining good safety profiles. However, the researchers emphasized that success required proper medical supervision, following established protocols, and regular monitoring through lab work and clinical visits.
This research supports the use of VLCKD as a viable option in clinical practice when patients are appropriate candidates and receive proper medical oversight, helping address previous concerns about the safety of very restrictive ketogenic approaches for obesity treatment.
