Combining a reduced-calorie diet (1,500 ± 200 kcal) with moderate aerobic exercise produces significantly greater reductions in BMI, waist circumference, and body fat percentage compared to diet alone in overweight/obese women.
To lose fat and improve body composition, do not rely on diet alone. Combine a moderate caloric deficit (around 1,500 kcal) with regular moderate exercise (like brisk walking or cycling for 30+ minutes, 3-5 times a week). This combination is significantly more effective for reducing body fat and waist size than dieting by itself.
A combination of a reduced-calorie diet with exercise may successfully reduce weight, BMI, WC and body fat levels.
Why this rating
Randomized controlled trial with a reasonably large sample size (n=206) and clear statistical significance, though limited by short follow-up.

- 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
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
