The Claim

In older adults with obesity and type 2 diabetes, supplementing with a leucine and vitamin D-enriched protein drink during a 3-month intensive lifestyle intervention does not result in sustained improvements in body composition or physical function 6 months after the intervention ends, despite observed short-term benefits, indicating that continued high protein intake may be required to maintain any advantage.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect

In plain English

If older adults with obesity and type 2 diabetes drink a special protein shake with leucine and vitamin D for 3 months, it might help at first—but the benefits don’t last 6 months after stopping, unless they keep eating lots of protein.

See the scientific wording

Supplementing with a leucine and vitamin D-enriched protein drink during a 3-month intensive lifestyle intervention does not lead to sustained differences in body composition or physical function 6 months after the intervention ends in older adults with obesity and type 2 diabetes, despite previous short-term benefits, suggesting that continued high protein intake may be necessary to maintain any advantage.

What the research says

  1. Study: Long‐term preservation of lean mass and sustained loss of fat mass after completion of an intensive lifestyle intervention in older adults with obesity and type 2 diabetes

    The study found that older adults kept some benefits from a short-term diet and exercise program even 6 months later, but those who drank the special protein shake didn’t do better than those who didn’t, so the extra protein didn’t help in the long run.
