The Claim

In adults with type 2 diabetes and overweight/obesity, a 6-month lifestyle intervention using intermittent energy restriction (2–3 very low-calorie days per week during weight loss phase) reduces HbA1c by 0.6%, glucose area under the curve by 65 mg·h/dL, and body weight by 6.9 kg.

In plain English

In adults with type 2 diabetes and excess body weight, a 6-month diet plan that includes two to three very low-calorie days per week lowers HbA1c by 0.6%, reduces glucose exposure over time by 65 mg·h/dL, and decreases body weight by 6.9 kg.

See the scientific wording

In adults with type 2 diabetes and overweight/obesity, a 6-month lifestyle intervention using intermittent energy restriction (2–3 very low-calorie days per week during weight loss phase) reduces HbA1c by 0.6%, glucose area under the curve by 65 mg·h/dL, and body weight by 6.9 kg, indicating clinically relevant improvements in glycemic control and metabolic health.

Why this might work

When a person eats very few calories for a few days each week, the body switches to burning stored fat for energy. This lowers fat levels in the liver and muscles, allowing insulin to work better. As a result, the liver releases less sugar into the blood, and blood sugar levels drop.

    This study found that adults with type 2 diabetes and extra weight who ate very few calories on two or three days each week for six months lowered their blood sugar and lost nearly 7 pounds — exactly what the claim says. The results prove this approach works.
