High fiber low fat diet followed by detox diet is the best diet for weight loss.take plenty of water everyday. Take small and frequent meals at regular intervals. Avoid outside food completely. Ask me directly for customized diet plan for you. 

Take oatmeal , besan or moong dal cheela or dhokla / khandvi / vegetable sandwich / vegetable daliya / Fruit chat or sprouts in breakfast.
