Weight loss is essentially a case of simple mathematics. If you use up more calories than you consume you will lose weight. What could be easier!
Unfortunately, life is never that simple, and there are always a few other equations to take into account.
The basics maths
What's the best way to create a calorie deficit?
Try to lose more calories through exercise as opposed to nutrition. If nutrition is restricted past the point of basic daily functioning then the metabolic rate starts to drop and the body can actually start to store fat as protection against a possible 'famine'.
Calculating your optimum heart rate during exercise
Use the equation 220 minus your age to give you an approximate figure for your maximum heart rate (the figure you should go no higher than when exercising).
Using this figure you can then calculate what percentage of your maximum you're working at during exercise. To maximise your cardiovascular benefits and calorie expenditure it is recommended that you work around 60-80% of your maximum heart rate.
If you enjoy exercising and don't mind pushing yourself, then incorporate sessions into your plan where you do try to work harder. The harder you work (75-95% max heart rate), the more calories expended during the session and in the 24 hours after, as you have revved up your metabolic rate. Just be aware that the harder you work, the less duration you will be able to maintain it for, so don't expect the session to last for as long.
