B · Reasonable confidenceStrength training, diet or both: effects on fat mass in women
Subject: Resistance Training Combined With Diet Decreases Body Fat While Preserving Lean Mass Independent of Resting Metabolic Rate: A Randomized Trial
What this means
All three treatment groups lost fat mass, with the steepest decrease for strength training plus diet. Only the strength-training-only group showed a significant gain in lean mass.

What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
Forty premenopausal women received resistance training, a diet, both, or no intervention. All three intervention groups lost fat mass, most with resistance training plus diet. Only the resistance-training-only group showed a significant increase in lean mass. Resting metabolic rate did not change significantly in any group.
Who this applies to
Premenopausal female volunteers.
Size of the research
One trial with 40 women, split into four groups of 10.
What to keep in mind
Small groups of 10 women. Both diet groups ate a high protein intake of 3.1 g per kg body weight per day; results may differ with other eating patterns.
Practical conclusion for REZA
Supports resistance training during a diet: the combination produced the most fat loss. A protective effect on resting metabolic rate was not shown in this study.

Methodology
Randomized controlled trial (RCT)
Population
40 premenopausal women, four groups of 10; protein intake in the diet groups 3.1 g/kg/day
Intervention
Diet + RT vs diet alone
Outcome measures
Body fat, lean mass, resting metabolic rate
Limitations
Small study (10 per group) in premenopausal women only; very high protein intake in the diet groups; short duration.
