Researchers compared two different diet approaches for severely obese teenagers to see which was more effective and safe for weight loss. One group followed a high-protein, very low-carbohydrate diet (only 20 grams of carbs per day), while the other followed a traditional low-fat diet (30% of calories from fat). Both groups were closely monitored by medical professionals for 13 weeks to ensure safety.
The study included 46 teenagers, with 33 completing the full intervention period. Both diet approaches led to significant weight loss as measured by BMI-Z-scores (a standardized measure of weight for age and height). However, the high-protein, low-carb group achieved greater weight loss during the active intervention period. When researchers checked back with participants at 24 and 36 weeks, both groups had maintained their weight loss, though the difference between approaches was no longer significant.
Importantly, the study found no serious safety concerns with either diet approach. Researchers monitored heart function, metabolic markers, and other health indicators throughout the study. Contrary to what might be expected, the high-protein diet didn't preserve lean muscle mass better than the low-fat approach, though both diets were considered safe when medically supervised.
This research suggests that for severely obese adolescents, a high-protein, very low-carbohydrate approach can be an effective and safe option when implemented under medical supervision. At VALIA Health, this type of evidence helps inform personalized nutrition strategies, particularly for patients struggling with significant weight management challenges where traditional approaches may not have been successful.
