Resistance training (RT) during diet-induced weight loss conserves fat-free mass (FFM) and resting energy expenditure (REE), whereas aerobic training (AT) and no exercise do not.
If you are losing weight through diet, add resistance training 3 times a week. This protects your muscle mass and keeps your metabolism from slowing down as much as it would if you only did cardio or no exercise. Focus on progressive overload, starting with lighter weights and increasing them as you get stronger.
Regardless of race, RT maintained FFM (P ≤ 0.05) following weight loss... whereas AT... and NT... decreased FFM... Both AT and NT decreased in REE with weight loss but RT did not.
Why this rating
Randomized controlled trial with clear statistical significance (P ≤ 0.05) for the primary outcomes, though sample size is moderate (n=94).

- 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
