How to lose weight the healthy way
The healthiest way to lose weight is neither crash diets nor bursts of exercise. The body likes slow changes in terms of food and exercise.
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:
This is why experts talk about weight loss in terms of diet and exercise.
Introduce changes gradually
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.
No matter if you hate gyms - even light exercise such as a short 20 minute walk will be beneficial if done most days of the week.
Every single time you exercise more than usual, you burn calories and fat.
There are lots of ways to increase the amount of activity you do. Team sports, racket sports, aerobics classes, running, walking, swimming and cycling will all improve your fitness levels.
Find something you enjoy that's easy for you to do in terms of location and cost. You are then more likely to build it into your routine and continue to exercise, despite inevitably missing the odd session through holidays, family commitments, etc.
Reduce your calorie intake
A BMI of 18.5-25 is healthy.
If you have a BMI of more than 25 you are overweight.
Over 30 is obese.
Over 40 is morbidly obese.
To calculate your BMI, you'll need to know your weight in kilos and your height in metres, then follow the example below.
1. Multiply your height by itself, eg 1.7x1.7= 2.89.
2. Divide your weight (eg 80kg) by this figure.
3. 80 ÷ 2.89= 27.7.
27.7 is the BMI.
Write down your plan
You can use a notebook or an online diary.
At the end of the week, review your entries for problem areas.
Look out for processed foods, alcohol, fast food, roasts, creamy sauces and fried foods.
If your diet seems largely healthy, look at portion sizes.

Week 1
You could use a table like the one below to keep track of your goals, marking your progress for each day with a tick or a cross.
Keeping your motivation up is one of the most difficult aspects of dieting. There will be days when healthy eating goes out the window and there will be weeks where you may not lose any weight – or put a little back on.
This is normal for everyone – dieters or not – so don't let it undo your plans for a slimmer you. You're not doing anything 'wrong', but you may need to look at your plan. Do you need to increase your activity levels? Make a few more changes to your diet? Put more effort into sticking to your current plan?
The other side of this is to make sure you celebrate your goals. While there is joy enough in stepping on the scales and seeing them dip lower, be sure to mark long-term progress with a reward such as new clothes or a night off from housework.
Celebrating is also a way to involve your nearest and dearest – it's up to you whether you want their encouragement in the form of gentle reminders not to eat certain foods, but support from other people can get you through the bumpy patches.
Health benefits of weight loss
Generally, we gain weight as we age. A few pounds over the years are not a problem, but people who gain more than 20lb compared to their weight as an 18-year-old will rapidly increase their risk of health problems due to that extra weight. In particular, women increase their risk of heart attack and double their risk of dying from cancer.
It may seem like these are problems to worry about in the future, but time flies by and tomorrow becomes today. By keeping your weight in the healthy range, you are less likely to be troubled by illnesses in your later years.
Once you start your plan, weigh yourself once a week before breakfast. Keep a record of this weight and see if a pattern develops.

It might take a week or two before you notice any changes, but they will steadily appear. After the first month you will be able to see the results and measure them in terms of looser fitting clothes.
Studies show that overweight women who lose between 10lb and 20lb halve their risk of developing diabetes. For men, the risk of heart problems reduces considerably.
