Yes, they can be included in a diet program. Besan recipes are ideal for losing weight and this is something that most people don't realize. My sister went through a dieting phase and she ate only wheat based products. She gave up rice and all forms of carbs and stuck to things such as rotis and chapattis. She actually lost around six or seven kilos in a matter of three months. But you must remember that you should add any ghee or butter to the breads. This will be counter productive and you will gain weight. In fact avoid using oil as well.
