The Claim
Long-term combined diet and physical activity interventions reduce the incidence of type 2 diabetes by approximately 50% compared to usual care in adults with overweight or obesity, independent of the magnitude of weight loss, through improved insulin sensitivity and cardiorespiratory fitness.
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 overweight or obesity, sustained changes in diet and physical activity lower the rate of type 2 diabetes development by about half compared to standard care, regardless of how much weight is lost, due to improved insulin sensitivity and cardiorespiratory fitness.
See the scientific wording
Long-term combined diet and physical activity interventions reduce the incidence of type 2 diabetes by approximately 50% compared to usual care in adults with overweight or obesity, independent of the magnitude of weight loss, suggesting benefits mediated through improved insulin sensitivity and cardiorespiratory fitness.
When a person eats better and moves more over time, their muscles become better at pulling sugar from the blood using more transporters and more energy factories inside cells. This lowers blood sugar levels and stops the pancreas from overworking, which prevents diabetes from developing.
What the research says
1 studyPeople with extra weight who eat better and exercise regularly for a long time cut their chances of getting type 2 diabetes in half—even if they don’t lose much weight—because their body uses insulin better and their heart and lungs get stronger.
