The Claim
In inactive young adults, very low-intensity leg cycling (no-load cycling) increases energy expenditure by approximately 1.6 to 1.75 times resting levels and decreases respiratory quotient (RQ) by 0.03 to 0.04 units, indicating a shift toward greater fat oxidation without significant changes in carbohydrate oxidation, suggesting that minimal physical activity can enhance fat metabolism relative to sedentary sitting.
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.
Even super light leg pedaling while sitting can help your body burn more fat than just sitting still — and you don’t need to break a sweat for it to work.

What the research says
1 studyStudy: Dynamics of Fat Oxidation from Sitting at Rest to Light Exercise in Inactive Young Humans
The study looked at light leg cycling in inactive young people and found it helps the body burn more fat compared to just sitting, without feeling hard. This supports the idea that even very easy exercise can shift the body to use more fat for energy.
