Why do different people have different calorie needs?
Life Style - Calorie needs are also heavily influenced by lifestyle. Physically active individuals require more energy than those who have a more sedentary lifestyle. The extra energy demands are not only to fuel the extra activity, but also to sustain higher BMR, even when at rest. There are a number of reasons for this, but one important reason is that those who are physically active develop more muscle tissue. Muscle tissue is more metabolically active than fat tissue, so a body which is more muscular than another body of the same weight will burn more energy at all times than the more ‘fatty’ body. Male hormones encourage the development of muscle tissue, hence men have relatively more muscle and less fat than women, and a man weighing 60kgs can eat slightly more calories each day than a woman without gaining weight!

Why do I need to learn about calories?
The key to weight management is learning to balance calories consumed with calories expended. To maintain a healthy weight, they need to be equal.
This often requires tradeoffs—more physical activity to balance calories consumed, or more calories in when you are especially active, or fewer calories in if you are not expending as many as you are taking in.
Fortunately, there are no “good” or “bad” foods or beverages. It’s possible to fit all of your favorites into an active, healthy lifestyle through balance, variety and moderation—and being physically active. It’s not ‘what’ you consume, but the ‘how and how much’ in relationship to your nutritional needs and energy requirements
