Why Can't I Lose Weight?
100% Online — No Office Visit Required
Weight loss resistance is often biological, not a willpower problem. Understanding the underlying factors can help frame why medical treatment options exist.
Overview
The 'just eat less and move more' approach fails many people because weight is regulated by complex hormonal, neurological, and metabolic systems — not just calorie math.
Common Causes
Common biological factors that contribute to weight loss resistance:
- Elevated set point regulation — the body actively defends its weight
- Leptin resistance — reduced satiety signaling
- Insulin resistance and hyperinsulinemia
- Thyroid dysfunction
- Chronic cortisol elevation (stress)
- Sleep deprivation and circadian disruption
- Genetic predisposition
- Gut microbiome dysbiosis
Common Questions
Can a medication help if diet and exercise haven't?
For many people, yes. GLP-1 medications address hormonal pathways that diet alone cannot. They've been shown to produce significant weight loss even in people who haven't responded to lifestyle interventions alone.
