The Claim

Intermittent fasting significantly improves glycated hemoglobin (HbA1c), fasting plasma glucose, body weight, BMI, waist circumference, systolic and diastolic blood pressure, low-density lipoprotein cholesterol, and total cholesterol levels in adults with type 2 diabetes compared to control diets.

Cause and effect
1 study reviewed
In plain English

In adults with type 2 diabetes, intermittent fasting lowers glycated hemoglobin, fasting blood glucose, body weight, BMI, waist size, blood pressure, and cholesterol levels compared to regular eating patterns.

See the scientific wording

Intermittent fasting significantly improves glycated hemoglobin (HbA1c), fasting plasma glucose, body weight, BMI, waist circumference, systolic and diastolic blood pressure, low-density lipoprotein cholesterol, and total cholesterol levels in adults with type 2 diabetes compared to control diets, based on a meta-analysis of 16 randomized controlled trials involving 5,369 patients.

Why this might work

When a person eats less often, the body uses up stored sugar for energy, then starts burning fat instead. This lowers blood sugar and fat levels, makes the body respond better to insulin, and reduces fat around the waist and liver. As a result, blood pressure and cholesterol also drop because the body is under less metabolic stress.

  1. Study: Intermittent fasting for glycemic control in patients with type 2 diabetes: a meta-analysis of randomized controlled trials.

    This study found that adults with type 2 diabetes who tried intermittent fasting had better blood sugar, lost weight, had smaller waists, lower blood pressure, and healthier cholesterol levels than those who ate normally — exactly what the claim says.
