Energy balance

Intensive lifestyle modification in type 2 diabetes yields only transient weight loss and fails to reduce cardiovascular mortality or clinically relevant endpoints compared to conventional care.

Intensive lifestyle programs for type 2 diabetes can help with short-term weight loss, but they do not prevent heart attacks or death in the long run. Do not feel pressured to achieve perfect lifestyle changes if they do not improve your cardiovascular outcomes, as the evidence for mortality benefit is lacking. Focus on manageable habits rather than extreme regimens.

The benefit described by Pfeiffer and Klein is pronounced only in the first year and then continuously tails off. At the end of the fourth year, the surrogates of the intervention group hardly differ from those in the control group. The study was terminated prematurely after 9.6 years because in spite of intensive lifestyle modification, the rate of clinically relevant end points (cardiovascular death, myocardial infarction, stroke, admission to hospital for angina pectoris) was not reduced.
