Recent research has cast doubt upon the established dogma for diabetes prevention, which traditionally insisted on mandatory weight reduction. Authors of a study appearing in Nature Medicine posit that blood sugar concentration can be normalized even without shedding pounds.
Prediabetes describes a condition where sugar levels are already elevated but have not yet met the diagnostic threshold for diabetes. This condition affects a substantial portion of the global adult population. Standard recommendations for these patients involve dietary modifications and body mass reduction. In practice, not everyone achieves these goals, and the incidence of diabetes continues to rise.
The new study demonstrated that approximately one-quarter of participants in lifestyle intervention programs saw their sugar levels return to normal without any accompanying weight loss. Furthermore, this method provided equivalent protection against developing diabetes as measures focused on body mass reduction.
New evidence suggests that the critical determinant is not the total amount of fat, but rather its spatial distribution within the body. Visceral fat, which encases internal organs, is known to incite inflammation and impair insulin function. Subcutaneous fat, conversely, is often linked to a healthier metabolic profile.
In the subjects of the experiment who achieved prediabetes remission without weight loss, a redistribution of fat from visceral areas to subcutaneous depots was observed, even while their body weight remained constant. Hormones governing glucose concentration also play a significant role. For instance, the hormone GLP-1, which boosts insulin production, showed greater activity in those individuals who entered remission without losing weight.
These findings, naturally, do not negate the advantages of weight loss, but they do shift the focus: the primary objectives are managing glucose levels and metabolic health. Practically speaking, this implies that strategies specifically targeting the reduction of visceral fat are highly effective. Examples include the Mediterranean diet paired with aerobic exercise.
