Many people lost wieght only dieting. But the question is, is your lever of physical work healthy for you? Your bones, muscles and all other internal and external organs need sufficient movement. Which we call workout. Google search might give many many results. All of them might not be healthy for you. Neither diet nor exercise ideas. It's always advisable if you look around authority sites like "webmd" or "nhschoice"... etc and try to have some healthy weight loss ideas. Try to keep yourself away from any artificial, quick weight loss, high protein, low carb......etc methods. Just look around first. Once your concept is clear, start trying something. Please don't focus on any plateau. There is nothing like that. Focus on HEALTH. You need to find the best healthy weight according to your body configuration, sex and age and set your goal there. If you stuck somewhere, you should understand, something is going wrong. Find out and correct it, you'll reach your goal. Thanks.
