For example, someone who has not exercised for years should not rush into running miles a day or pounding the treadmill. Not only will the struggle to do so leave you feeling disheartened and demotivated, you're also far more likely to injure yourself and set your fitness levels back further.
The same goes for people who suddenly start starving themselves. Diets that severely restrict calories or the types of food 'allowed' can lead you to be deficient in the nutrients and vitamins that your body needs.
So if you need to lose weight, what should you do?
Energy needs and weight loss
Your body uses food for energy. It stores any excess energy as fat. This means if you eat more food than your body needs for daily activities and cell maintenance, you will gain weight. To lose weight, you need to get your body to use up these stores of fat. The most effective way to do this is to:
​​​
-
reduce the number of calories you eat
-
increase your levels of activity.
This is why we should talk about weight loss in terms of diet and exercise.
Introduce changes gradually
Energy needs and weight loss
Small changes can make a big difference. One extra biscuit a week can lead you to gain 5lb a year – cut that biscuit out of your diet and you'll lose the same amount. You are also more likely to stick to, say, swapping full-fat milk for semi-skimmed or making time for breakfast each morning than a diet that sets rules for all foods. You should think of weight loss in terms of permanently changing your eating habits. While weight-loss goals are usually set in term of weeks, the end game is to sustain these changes over months and years.
Increase your activity levels
Someone who increases the amount they exercise, but maintains the same diet and calorie intake, will almost certainly lose weight.
