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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyThis 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.
