The Study
Comprehensive Analysis of Intermittent Fasting on Anthropometric Indices, Glycemic Control, and Serum Insulin Levels in Obese Patients with Type 2 Diabetes
This study watched what happened to 30 people who tried eating only during an 8-hour window for four weeks. It saw that their weight and blood sugar went down, but it didn't compare them to people who didn't fast — so we can't say the fasting definitely caused the changes.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
People with type 2 diabetes who ate only during an 8-hour window each day for four weeks lost a little weight and their blood sugar went down, but their insulin levels didn't change.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1These changes are modest but meaningful—lower blood sugar helps manage diabetes, even without insulin changes, suggesting fasting may help through other pathways.
- 2Weight dropped by 1.64 kg, BMI by 0.44 kg/m², waist by 0.51 inches, waist-hip ratio by 0.02, and fasting blood sugar dropped from 160 to 140 mg/dL.
- 3Insulin stayed the same.

Intermittent fasting lowers blood glucose levels and increases insulin sensitivity in people with type 2 diabetes and prediabetes.
Among obese adults with type 2 diabetes, following a 16:8 intermittent fasting schedule for four weeks is linked to a drop in fasting blood glucose levels from 160.25 mg/dL to 140.50 mg/dL.
Among obese adults with type 2 diabetes, following a 16:8 intermittent fasting schedule for four weeks is linked to a small but measurable decrease in waist size and waist-to-hip ratio.
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.
Obese adults with type 2 diabetes who followed a 16:8 intermittent fasting schedule for four weeks experienced an average decrease in BMI of 0.44 kg/m².
In obese adults with type 2 diabetes, following a 16:8 intermittent fasting schedule for four weeks does not change insulin levels in the blood, even though blood sugar levels go down.
