The Claim

In women aged 30–50 with obesity undergoing early rehabilitation after bariatric surgery, daily creatine supplementation (8 g prior to strength training three times per week for 8 weeks) has no significant effect on the loss of skeletal muscle mass compared to placebo, despite equivalent reductions in weight and fat mass between groups.

Cause and effect
1 study reviewed
In plain English

In women aged 30–50 with obesity recovering from bariatric surgery, taking 8 grams of creatine daily before strength training three times a week for eight weeks does not reduce muscle loss more than taking a placebo, even though both groups lose the same amount of weight and fat.

See the scientific wording

In women aged 30–50 with obesity undergoing early rehabilitation after bariatric surgery, daily creatine supplementation (8 g prior to strength training three times per week for 8 weeks) does not significantly reduce the loss of skeletal muscle mass compared to a placebo, despite both groups experiencing similar weight and fat mass loss.

Why this might work

When the body is losing weight rapidly, it breaks down muscle for energy. Creatine does not change how much muscle is built or broken down during this time, so muscle mass stays the same whether creatine is taken or not.

  1. Study: Creatine Supplementation Prior to Strength Exercise Training Is Not Superior in Preventing Muscle Mass Loss Compared with Standard Nutritional Recommendations in Females After Bariatric Surgery: A Pilot Study

    For women who just had weight-loss surgery, taking creatine before their strength workouts didn't help them keep more muscle than taking a sugar pill—even though both groups lost the same amount of weight. So creatine didn't make a difference here.
