If you’re looking to lose weight, the huge number of diet plans and nutritional guidance available can seem overwhelming, with many competing ideas and eating styles on offer. However, a good starting point for any weight control plan is to gain an understanding of calories, and what they mean for your body. While a calorie-tracking approach to nutrition can help build an understanding of which types of food may be best for achieving healthy weight loss goals, it may not suit everyone. If you’re overly concerned about your weight, speak to your doctor, a dietician or a nutritionist who may be able to work up a meal plan that suits your body type. Calories are a measure of the energy that food and drink provide to our bodies, and are vital fuel that we need to function.
