TL;DR
A structured weight loss program helped adults with type 2 diabetes lose weight and lower blood sugar levels over one year.
What they did
Researchers studied 227 adults with type 2 diabetes who were overweight or had obesity. They split participants into groups that received lifestyle counseling or usual care. The counseling groups followed either a lower-carbohydrate or a lower-fat meal plan.
What they found
People in the lower-carbohydrate group lost 9.0% of their body weight, the lower-fat group lost 7.4%, and the usual care group lost 2.5%. After 1 year, fasting glucose was 141 mg/dL in the intervention groups compared with 159 mg/dL in usual care. The lower-carbohydrate group also had a lower hemoglobin A1c of 6.6% compared with 7.2% in the higher-carbohydrate group.
Why it matters
Studies suggest that cutting back on carbohydrates may help people manage their blood sugar. Following a structured meal plan is also linked to greater weight loss. These eating habits may help support long-term metabolic health.
Limits

Jargon explained
- Hemoglobin A1c
- A blood test that shows average blood sugar levels over the past two to three months.
- Fasting glucose
- The amount of sugar in the blood after going without food for several hours.
- Triglycerides
