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.
GoodSupportsHIGH confidence
Subjects who increased from 1,674 to 4,185 kj (400 to 1,000 calories) had worse fasting glycemic control in spite of continued weight loss.
Why this rating
Randomized controlled trial with clear isolation of variables.
