The Claim
An 8-week intervention combining a 1,300 kcal/day low-carbohydrate diet with 18-hour daily intermittent fasting in obese adults with type 2 diabetes is associated with a 9.4% reduction in body mass index, a 15% decrease in HbA1c from 8.19% to 6.99%, and a 63% reduction in the triglyceride-to-HDL cholesterol ratio.
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 obese adults with type 2 diabetes, following a 1,300 calorie per day low-carbohydrate diet and eating only during a 6-hour window each day for 8 weeks is associated with a 9.4% drop in body mass index, a 15% drop in blood sugar levels, and a 63% improvement in the triglyceride-to-HDL cholesterol ratio.
See the scientific wording
In obese adults with type 2 diabetes, an 8-week intervention combining a 1,300 kcal/day low-carbohydrate diet with 18-hour daily intermittent fasting was associated with a 9.4% reduction in body mass index (BMI), a 15% decrease in HbA1c from 8.19% to 6.99%, and a 63% reduction in the triglyceride-to-HDL cholesterol ratio, suggesting improved metabolic health and reduced cardiovascular risk.
When carbs are severely limited and food is only eaten in a short daily window, the body runs out of stored sugar and starts burning fat for energy. This produces ketones, which replace sugar as the main fuel. With less sugar and insulin in the blood, the liver and muscles become more responsive to insulin. The liver stops making excess fat and starts breaking down fat instead, which lowers bad fats in the blood and improves good cholesterol. Fat loss from the liver and muscles removes blockages that were preventing insulin from working properly.
What the research says
1 studyIn obese adults with type 2 diabetes, eating only during a 6-hour window each day (and fasting the other 18 hours) while cutting carbs led to major improvements: they lost weight, their blood sugar dropped, and their blood fat levels became healthier—all exactly as the claim says.
