The management of type 2 diabetes has long been a challenge,
but a new study conducted by researcher Mark Lyngbaek and his
colleagues has the potential to add important considerations to the
approach to treatment. Titled the “DOSE-EX” randomized clinical
trial, their study uncovers the impact of exercise and weight loss
on beta-cell function, a key factor in diabetes progression.
DOSE-EX is a four-armed randomized trial involving 82 individuals
with newly diagnosed type 2 diabetes. The participants were divided
into four groups: standard care, calorie restriction, calorie
restriction with exercise three times per week, and calorie
restriction with exercise six times per week. Over a span of 16
weeks, the researchers assessed the effects of these interventions
on beta-cell function using various indicators.
The study’s findings are incredibly interesting, demonstrating that
exercise in combination with diet-induced weight loss leads to a
substantial improvement in glucose-stimulated beta-cell function.
Importantly, the results indicate the importance of considering
both: a) the exercise dose, and b) the methodology of assessing
beta-cell function, when evaluating intervention effectiveness.
In this episode, Dr. Lyngbaek will elucidate the implications of
these findings for the management of type 2 diabetes. We will
explore the potential of exercise as a therapeutic tool, its
optimal dosage, and the considerations for integrating it into
individualized treatment plans.
