Summary:
The purpose of this study was to compare the effects of the Mediterranean Diet (MD) versus the Very Low-Calorie Ketogenic Diet (VLCKD) on reaching 5% weight loss and changes in body composition in overweight and obese adults. 374 overweight/obese adults were randomized to follow either the MD (n=191) or VLCKD (n=183) for up to 3 months or until 5% weight loss was achieved. - Anthropometric measurements (weight, BMI, waist circumference) and body composition analysis via bioelectrical impedance were assessed at baseline and monthly visits.
- The hypocaloric MD provided ~1500-1700 kcal/day with macronutrient composition of 15% protein, 30-
35% fat, 50-55% carbs. - The VLCKD provided <800 kcal/day with <30-50 g carbs/day, higher protein, and lower fat.
Findings
- 5% weight loss was achieved after 1 month on VLCKD and after 3 months on MD.
- Both diets significantly reduced weight, BMI, waist circumference and fat mass. - The MD group had greater reductions in waist circumference and fat mass percentage compared to VLCKD.
- MD also increased total body water and fat-free mass percentage more than VLCKD. - When stratified by gender, age and BMI, the MD continued to show favorable changes in body composition compared to VLCKD. - No reductions in fat-free or body cell mass were seen with either diet.
In conclusion, both MD and VLCKD effectively achieved 5% weight loss and improved body composition, but over different timeframes. The MD led to greater waist circumference and fat mass reductions while preserving lean mass compared to VLCKD. These findings can help guide nutrition recommendations for weight loss and body composition goals in overweight/obese adults.
Questions:
1. Was energy intake precisely matched between the MD and VLCKD groups? The study states that the MD provided approximately 1500-1700 calories per day while the VLCKD was less than 800 calories per day. However, it's unclear if total daily energy intake was precisely matched between the groups. Even if the diets had the same macronutrient distribution, a major difference in calorie intake could impact the rate and amount of weight loss. Matching calories more closely between groups could help isolate the effects of the dietary patterns themselves.
2. Were participants provided specific meal plans and foods or just general diet advice?
