The Claim
In adults with prediabetes or moderately controlled type 2 diabetes, a 6-month calorie-restricted diet, whether standardized low-fat or personalized based on postprandial glucose predictions, results in similar small reductions in glycemic variability (mean amplitude of glycemic excursions decreased by approximately 0.8 mg/dL per month) and HbA1c (approximately 0.02% per month), indicating that algorithm-driven personalization provides no additional benefit over standard dietary guidance when both groups receive identical calorie restriction and behavioral counseling.
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 prediabetes or type 2 diabetes, a 6-month calorie-restricted diet leads to the same small reductions in blood sugar fluctuations and HbA1c levels whether the diet plan is standardized or personalized using glucose predictions, as long as both groups consume the same number of calories and receive the same behavioral counseling.

When a person eats fewer calories, the liver makes less sugar and the body's muscles and fat cells respond better to insulin, which lowers blood sugar swings and long-term average blood sugar levels.
What the research says
1 studyWhen people with early diabetes followed either a simple low-fat diet or a diet personalized by an app, both groups saw almost the same tiny improvements in blood sugar levels — proving the fancy app didn’t help more than a basic plan when both ate the same number of calories.
