The Claim

In adults with type 2 diabetes, 16 weeks of fasted morning aerobic exercise results in a greater reduction in intramuscular fat (−1.0 mL) compared to postprandial aerobic exercise, which leads to an increase in intramuscular fat (0.6 mL).

In plain English

In adults with type 2 diabetes, performing aerobic exercise in the morning before eating reduces intramuscular fat by 1.0 milliliters over 16 weeks, while performing the same exercise after eating increases intramuscular fat by 0.6 milliliters.

See the scientific wording

In adults with type 2 diabetes, 16 weeks of fasted morning aerobic exercise is associated with a greater reduction in intramuscular fat (−1.0 mL) compared to postprandial exercise, which increased intramuscular fat by 0.6 mL, suggesting a potential benefit for improving muscle metabolic health.

Why this might work

When a person exercises in the morning after not eating overnight, their body has low sugar and insulin levels, so it burns fat for energy instead. This causes fat stored inside muscle fibers to break down and be used as fuel. Over time, this reduces the amount of fat inside the muscles, which allows insulin to work better and helps the muscles take up sugar from the blood more efficiently.

  1. Study: HbA1c and Liver Fat After 16 Weeks of Fasted versus Fed Exercise Training in Adults With Type 2 Diabetes

    This study found that people with type 2 diabetes who walked before breakfast lost more fat inside their muscles than those who walked after eating, which could help their muscles use insulin better.
