Oral semaglutide: a small study of diet and body composition
This prospective study followed 25 Japanese people with type 2 diabetes taking oral semaglutide over three months. It assessed dietary intake and body-composition measures. Its small size, population and formulation limit generalisation; it does not prove muscle preservation for people using other semaglutide products.

Evidence and limits
The study followed 25 Japanese adults with type 2 diabetes for three months, using dietary questionnaires, bioimpedance measurements and handgrip testing. The authors reported body-weight and dietary changes and a higher percentage of muscle mass, with no significant handgrip change. A percentage is not proof that absolute muscle mass or strength was preserved.
What we checked
We checked the primary publication record and available abstract. The full paper and supplements have not been reviewed for this correction.
SHIFT’s take
Body composition, muscle percentage and strength are different measures. This small diabetes study does not prove that a different semaglutide formulation preserves muscle during weight loss.
