Energy balance

Weight loss through caloric restriction and dietary modification significantly reduces psoriasis severity (PASI score) and systemic inflammation in obese patients.

If you have psoriasis and are overweight, losing weight is one of the most effective non-pharmacological interventions available. Studies show that losing about 12% of your body weight through structured dietary programs (like very low-calorie ketogenic diets followed by balanced diets) can significantly reduce the severity of your psoriasis symptoms, often achieving a 50-75% improvement in skin clearance. This works by reducing systemic inflammation driven by excess fat tissue.

clinical manifestations such as psoriatic flares improve with weight reduction and physical activity... a 12% weight reduction in patients with obesity resulted in a PASI decrease of 50–75%, with significant improvement in psoriasis severity and quality of life index score
