Summary

The relative risk of psoriasis and its severity are directly related to the body mass index (BMI).Patients with psoriasis likely undergo a vicious circle where obesity and skin disease reinforce each other. To investigate patients' opinion about their body weight (BW), the possibility of dietary approach to psoriasis, and to examine the adherence and the effects of hypo-energetic diet to maintain disease remission in obese patients a dedicated questionnaire was administered to 200 consecutive patients (125 men and 75 women) with moderate-to-severe chronic plaque psoriasis investigating whether diet factors could influence psoriasis severity and course. In second part of study, obese patients with psoriasis in remission (PASI improvement ≥ 75%) for at least 12 weeks after methotrexate therapy were randomly assigned to receive a hypo-caloric diet or free diet for 24 weeks, and then followed up for additional 12 weeks.

BEHAVIORAL

Weight Loss

The low-calorie diet was designed to achieve a loss of 5-10% of initial body weight. The caloric restriction was 500 kcal below the resting energy expenditure, as evaluated by the Harris-Benedict equation. Intervention group patients received a balanced diet scheme, based on a caloric intake reduction related to BMI and sex (range: 1200-1500 kcal/d for women, 1300-1600 kcal/d for men).
