The Claim

A 12-week protein supplementation program targeting 1.2–1.5 g/kg/day increased daily protein intake by 0.4 g/kg in frail older adults, and dietary counseling combined with whey protein supplements effectively raised protein consumption in this population.

In plain English

In frail older adults, a 12-week program of whey protein supplements and dietary counseling increased daily protein intake by 0.4 grams per kilogram of body weight.

See the scientific wording

A 12-week protein supplementation program targeting 1.2–1.5 g/kg/day increased daily protein intake by 0.4 g/kg in frail older adults, demonstrating that dietary counseling combined with whey protein supplements can effectively raise protein consumption in this population.

Why this might work

When frail older adults consume more protein from supplements and counseling, their blood gets more building blocks called essential amino acids, especially leucine. These amino acids directly stimulate muscle cells to start making more protein, which signals the body to maintain higher overall protein consumption. This happens because their bodies were not getting enough protein before, so adding more triggers a biological response that sustains the higher intake.

  1. Study: Effect of a protein intervention during resistance training with varying training intensities on muscle outcomes in frail community-dwelling older adults: a randomized controlled trial

    Giving frail older adults protein shakes and nutrition advice for 12 weeks helped them eat more protein — exactly as the claim says. It didn’t make everyone stronger, but it did make them eat more protein, which is what the claim is about.
