The principle for getting down to a healthier weight is straightforward.
The way you try to lose weight influences the proportions of fat and lean tissue that will be burned for fuel, how well your needs for protein, vitamins, and minerals are met, and what your fluid balance will be - all elements of nutritional health.
For most people, the best way to lose weight is a modest decrease of 2 000 to 4 000 Kilojoules a day, and a increase in physical, particularly aerobic, activity.
