Combining a low-calorie diet (960 kcal) with daily dumbbell exercise (20 min, 2kg) for 12 weeks reduces body fat and waist-to-hip ratio more effectively than low-calorie diet alone in mildly obese young women, while preserving fat-free mass.
For young women looking to lose fat, combining a strict low-calorie diet (around 960 kcal) with daily, short (20 min) dumbbell workouts (2kg) may help reduce body fat and waist size more than dieting alone, without losing muscle. The key is consistency and simplicity.
The results show that LCD for 12 weeks with and without dumbbell exercise decreased body weight and body fat without reducing FFM... The decreases in body weight, percent body fat, body fat weight, and BMI were larger when LCD was combined with dumbbell exercises, but no statistically significant difference was found.
Why this rating
Small sample size (n=12), short duration (12 weeks), and lack of statistical significance between groups limit generalizability.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
