Eight weeks of resistance training significantly improves phase angle, a marker of cellular health, in obese older women, independent of significant changes in body fat percentage.
If you are an older woman with obesity, engaging in resistance training for just 8 weeks (3 times a week) can significantly improve your cellular health, as measured by phase angle. This improvement happens even if you don't lose much body fat. Focus on performing 8 exercises with 3 sets of 8-12 reps, progressively increasing the weight as you get stronger, rather than just focusing on the number on the scale.
Our results suggest that 8 weeks of RT improves PhA—a cellular health parameter—in obese older women.
Why this rating
Randomized controlled trial with a control group, though limited by a small sample size (n=33) and short duration (8 weeks).

- 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
