Obesity is one of the greatest risk factors for osteoarthritis. Excess body weight affects arthritis by putting extra burden on the already fatigued joints. So, it is advisable to take recommended calories only and maintain ideal weight. Apart from keeping the meals as healthy as possible, obese individuals should eat a well-balanced diet, comprising of various food groups (cereals, pulses, milk and milk products, meat products, fruits, vegetables, fats and sugar).

In rheumatoid arthritis, if joint involvement is clearly traceable then one may have to modify the dietary pattern in consultation with a dietitian. Patients with chronic rheumatoid arthritis are considered to be at nutritional risk (i.e. prone to malnutrition) due to raised metabolic rate. In such cases, some intravenous supplementation may be required.
