Can you really lose weight by just watching your calories a day?

The most important part of weight loss is cutting back on calories and limiting fat, sugar, sodium, etc intake. However the best way to lose weight is to combine healthy eating and exercise. Make sure that even though you may cut on calories, the calories that you do eat are good calories and not empty ones.

Calories consumed - calories expended = fat

You can lose weight purely by cutting calories but it's not sustainable for a long time, and you'll probably end up feeling tired and grumpy and give up before any real change.

The best thing to do is work out how much weight you want to lose each week. A pound of fat is 3000 calories so if you decide on losing a pound a week that's roughly 430 calories a day less than usual.

This is a lot of calories to lose so I would advise cutting about 230 calories a day from your diet, and burning an extra 200 calories a day (30 mins jogging a day will do this). This way you will feel happy and energetic and lose weight that stays off. It takes a long time to go, but it took a long time to accumulate the extra weight so it makes sense.

The more exercise you do, the faster your metabolism, so it is the perfect system for weight loss.

The less you eat, the slower your metabolism, so it's rubbish.
