if you lose weight by dieting you will put it all back on again. The trick is to change your lifestyle especially your eating habits, It works for me I do not miss cakes,biscuits, sweets, CHOCOLATE, potatoes. because we do not buy them and temptation is not there. Try walking down the cake aisle of a supermarket with the sole intention of not buying anything, if you cannot get to the other end without buying anything then you will not lose weight.Putting on a pound in a week is equivalent to eating 2 1/2 loaves of bread too much or 6 packets of bicuits per week, that is nearly a packet of biscuit per day.
