Due to its high calorie content, jaggery can cause weight gain if ingested in excess. It is not calorie-free, but it is more nutrient-dense than refined sugar. Overindulging in jaggery, particularly if it isn't balanced with exercise, might eventually result in weight gain and fat storage. The issue is moderation; jaggery by itself won't always result in weight gain when used as a sweetener in small doses. Know more about Does jaggery increase weight
