Energy balance

Among patients with type 2 diabetes in placebo-controlled trials, baseline BMI has significantly increased over time (rising by ~0.70 kg/m² per decade), indicating a growing prevalence of obesity and inadequate management of weight despite improved glycemic control.

If you have Type 2 Diabetes, your weight is likely increasing even if your blood sugar is controlled. This meta-analysis of over 260,000 patients shows that baseline BMI has risen by 0.7 kg/m² every decade. You cannot ignore weight management; it is becoming harder, not easier, to maintain a healthy weight with current standard care. Focus on energy balance (diet and activity) as rigorously as you focus on glucose numbers.
