The Claim
After adjusting for BMI and other metabolic factors, insulin-stimulated lipogenesis in subcutaneous adipocytes is not independently associated with sedentary behavior.
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.
The rate at which insulin promotes fat storage in under-skin fat cells does not change based on how much a person sits, once body weight and other metabolic factors are accounted for.
See the scientific wording
Insulin’s ability to stimulate fat formation (lipogenesis) in subcutaneous fat cells is not independently associated with sedentary behavior after adjusting for BMI and other metabolic factors, indicating that this metabolic pathway is less sensitive to physical activity status than antilipolysis.
When a person is inactive, fat cells produce less of the proteins needed to detect insulin. This weakens insulin's ability to shut down fat breakdown, so more fat stays in the blood. But insulin's ability to tell fat cells to store sugar as fat remains unchanged because the later steps in the process still work normally.
What the research says
1 studyStudy: RELATIONSHIP BETWEEN A SEDENTARY LIFESTYLE AND ADIPOSE INSULIN RESISTANCE.
When people sit too much, their fat cells become less sensitive to insulin’s signal to stop breaking down fat, but they still respond normally to insulin’s signal to store fat from sugar. So sitting doesn’t hurt fat storage — just the ability to stop fat breakdown.
