Trying to solve a problem by creating another problem is definitely not ideal. If you are truly overweight and want to loose weight I would suggest you count you set up a daily calorie intake and count your calories every day aiming to loose about 0.5-1kg a week. Starving will only destroy your muscles and body in general which will be a problem after you lost the weight and want to tone up etc. Also starving your body from the nutrition it naturally requires will slowly if not already lead to other problems such as depression and more.If you are truly committed about changing your body weight, set up a calorie intake (there are lots of mobile apps that can help with this), exercise, look forward positively to the body you want to create and get some emotional support from friends or have someone as your dedicated cheer leader! This is not an overnight task but it can be life changing if you put your mind to it and stick to it.
