Energy balance

Increasing caloric intake from 400 kcal to 1,000 kcal worsens glycemic control despite continued weight loss, demonstrating that caloric restriction has an independent effect on glucose levels.

If you are an obese type II diabetic, simply losing weight might not be enough to maintain good blood sugar control if you increase your calories. The study suggests that maintaining a lower caloric intake is crucial for keeping glucose levels low, even if you continue to lose weight.
