The Claim
In overweight adults, resistance training performed at 20% or 40% velocity loss reduces postprandial respiratory quotient by 0.05–0.10 units compared to rest, indicating a shift from carbohydrate to mixed substrate utilization following a glucose load.
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 overweight adults, performing resistance training at 20% or 40% velocity loss after eating a glucose load results in a measurable decrease in respiratory quotient, indicating a greater use of fats alongside carbohydrates for energy compared to resting after eating.

After eating sugar, doing resistance training with high effort causes muscles to burn through their stored sugar quickly, which triggers signals that pull more sugar into muscles without needing insulin. This also turns on fat-burning machinery in muscles and releases fat from body fat stores, so the body starts using fat instead of sugar for energy even when insulin is high.
What the research says
1 studyAfter eating a sugary meal, doing light weightlifting made people’s bodies burn more fat and less sugar than just sitting still — and the harder the workout, the more fat they burned.
