Think about this and try to resist eating as soon as you feel hungry. Are you feeling physically hungry or are you just looking for food to fulfil an emotional hunger? If you do have a strong appetite, try to fill up at mealtimes with lots of leafy vegetables and fruit. These have a lot of fibre and bulk but are low in calories.Some companies and people claim diet pills make you lose weight. This may be true at first, but pills don’t help you keep the weight off.
