The Claim
In adults with type 2 diabetes, 16 weeks of fasted morning aerobic exercise results in a 58.3 mL greater reduction in visceral adipose tissue compared to postprandial aerobic exercise, which results in a 34.2 mL increase.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with type 2 diabetes, doing aerobic exercise in the morning before eating reduces visceral fat by 58.3 mL over 16 weeks, while doing the same exercise after eating increases visceral fat by 34.2 mL.
See the scientific wording
In adults with type 2 diabetes, 16 weeks of fasted morning aerobic exercise leads to a greater reduction in visceral adipose tissue (58.3 mL) compared to postprandial exercise, which resulted in a 34.2 mL increase, suggesting a potential benefit for reducing metabolically harmful fat depots.
When a person exercises in the morning after not eating overnight, their insulin levels are low and stress hormones are high. This triggers fat cells around the organs to release stored fat into the blood. The body uses that fat as fuel during exercise, especially from the deep belly area. Over time, this repeated process shrinks the fat depot around the organs more than exercising after eating.
What the research says
1 studyThis study found that people with type 2 diabetes who walked before breakfast lost more fat around their internal organs than those who walked after eating, suggesting that exercising on an empty stomach might be better for reducing harmful belly fat.
