The best way to keep your weight down is to make small changes to your eating habits and to your activity levels that you can keep to for life. In other words, it is more about changing your lifestyle than ‘going on a diet’.
The calories in your food and drink give your body the energy it needs. If you take in more calories than your body needs, it will store the extra energy as fat. And, if you take in fewer calories than your body needs, it will burn up the fat your body has stored to make up the difference.
So, to lose weight you need be more active to increase the amount of energy your body needs. You also need to eat less high-calorie food to reduce the amount of energy you take in. This is by far the most sensible and successful way to lose weight.
Set yourself realistic goals. Aim to lose around 5-10% of your overall weight over a period of 3-6 months. A weight loss of between 0.5-1 kilogram (1-2 pounds) a week is good.
Don't trying losing weight alone
It is not always easy losing weight, and you can quickly get bored or give up without encouragement. Get support from your family and friends, or if you think it might help, you could join a weight-loss group. Some people find that having support from other people who are also trying to lose weight can help.
