There are essentially three ways in which weightloss can be achieved permanently and quickly, and that is to eat a diet that is low-calorie but nutrient-dense (high water-content-foods)and only according to hunger, coupled with IF or Intermittent Fasting (one day of eating the above, and the next only water according to thirst, alternately).
And thirdly via the P.A.C.E. exercise programme (10 mins a day) and you will lose fat/weight even while you sleep................. http://alsearsmd.com/pace2/jvnb/
