The Claim

In obese adults with type 2 diabetes, a 16:8 intermittent fasting regimen applied for four weeks is associated with a mean reduction in body weight of 1.64 kg, a decrease in BMI of 0.44 kg/m², a reduction in waist circumference of 0.51 inches, a lowering of waist-hip ratio by 0.02, and a reduction in fasting blood glucose from 160.25 mg/dL to 140.50 mg/dL, with no change in serum insulin levels.

In plain English

Obese adults with type 2 diabetes who followed a 16:8 intermittent fasting schedule for four weeks experienced measurable decreases in body weight, BMI, waist size, waist-hip ratio, and fasting blood glucose, with no change in serum insulin levels.

See the scientific wording

In obese adults with type 2 diabetes, a 16:8 intermittent fasting regimen for four weeks is associated with a mean reduction in body weight of 1.64 kg, a decrease in BMI of 0.44 kg/m², a reduction in waist circumference of 0.51 inches, and a lowering of waist-hip ratio by 0.02, alongside a mean reduction in fasting blood glucose from 160.25 mg/dL to 140.50 mg/dL, suggesting potential short-term metabolic benefits without changes in serum insulin levels.

Why this might work

When eating is limited to an 8-hour window, the body runs out of food energy and starts burning stored fat for fuel. This lowers the amount of sugar made by the liver and reduces sugar levels in the blood. The body also uses up fat around the waist, making the waist smaller and lowering overall weight.

  1. Study: Comprehensive Analysis of Intermittent Fasting on Anthropometric Indices, Glycemic Control, and Serum Insulin Levels in Obese Patients with Type 2 Diabetes

    This study found that obese adults with type 2 diabetes who ate only during an 8-hour window each day for four weeks lost a little weight, shrank their waist, and lowered their blood sugar—without changing their insulin levels. That’s exactly what the claim says.
