Six weeks of either High Intensity Interval Training (HIIT) or Moderate Intensity Training (MIT) significantly improves insulin sensitivity, reduces blood lipids, decreases body fat percentage, and improves cardiovascular fitness in sedentary overweight or obese young men.
If you are a sedentary young man who is overweight, starting either high-intensity interval training (HIIT) or moderate-intensity continuous training (MIT) for just six weeks can significantly improve your insulin sensitivity, lower bad cholesterol, reduce body fat, and boost your cardiovascular fitness. While MIT showed a slight edge in improving maximum oxygen uptake (VO2peak), both methods were effective for overall cardiometabolic health. Choose the one you can stick with, knowing that even a small amount of exercise (as little as 1 hour a week for HIIT) yields benefits.
Participation in HIIT or MIT exercise training displayed: 1) improved SI, 2) reduced blood lipids, 3) decreased % body fat, and 4) improved cardiovascular fitness.
Why this rating
Randomized controlled trial with a small sample size (n=28) and short duration (6 weeks), limiting 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
- 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
