Breakfast makeover: simple diet change may tame diabetes
NCT ID NCT05986097
First seen Jun 25, 2026 · Last updated Sep 02, 2026 · Updated 3 times
Summary
This study tested a 4-month online program that encourages a very low-carbohydrate breakfast for adults with poorly controlled type 2 diabetes. Researchers measured how satisfied participants were, how well they stuck to the diet, and changes in blood sugar, weight, and medication use. The goal is to see if this simple breakfast change is a practical way to improve diabetes management.
