Enjoy it and you will want to carry on. Set realistic goals. Remember you cannot change your appearance beyond the bounds of physiological capabilities. As well as weight reduction or weight gain appearance can be enhanced by improved posture,change in dress style and colours,changes in hairstyles etc. We control many things but physical shape and size can be governed by genetics.
Fat reduction is usually within the capabilities of most overweight but otherwise healthy people.
Set a realistic easy to achieve goal for the first week. If you set a target of just one pound weight loss in the first week anything over that is a bonus. Be satisfied with small permanent losses over a period of time. We will gradually increase the targets to suit your individual needs.
