Nutritional guidance: through at least 2 individual assistance and group sessions, lasting 1 hour, weekly for 4 months, and biweekly for 2 months and monthly thereafter (26-28 meetings/1year).The diet plan will recommend a deficit from 500 to 750 kcal/day in order to promote loss of about 0.5kg/week, containing 1g/kg of protein per day (minimum 1200kcal/day), high in fiber, vegetables and whole foods.
