The Claim
Caloric restriction at 15% and 35% levels for 6-12 months is associated with improved metabolic profile in 12-month-old male Wistar rats, including reduced plasma glucose, insulin, and leptin levels compared to control rats.
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.
When older male rats eat less food for several months, their bodies process sugar better and have healthier hormone levels.
See the scientific wording
Caloric restriction at 15% and 35% levels for 6-12 months is associated with improved metabolic profile in 12-month-old male Wistar rats, including reduced plasma glucose (5.22-6.17 mmol/L vs 11.88-11.90 mmol/L in controls), insulin (0.513-0.650 ng/mL vs 1.52-4.371 ng/mL), and leptin (336-773 pg/mL vs 1427-3004 pg/mL) levels.
What the research says
1 studyStudy: Effect of Chronic Moderate Caloric Restriction on the Reproductive Function in Aged Male Wistar Rats
The study fed rats less food for 6-12 months and found they had better blood sugar and hormone levels, which matches exactly what the claim says.
