The overarching premise of weight loss is the idea that if we balance calories in and calories out we will maintain our weight, whereas if we eat more than we burn we will gain or eat less than we burn then we will lose weight. The first place to start is knowing about how many calories your body needs in order to maintain your weight. You can easily estimate this using a BMR and nutritional needs calculator. Your BMR is the number of calories your body needs each day just to perform basic functions and keep you alive – even if you stayed in bed all day! You nutritional needs include your BMR plus your daily activity. Taking the value of your nutritional needs and decreasing it by a couple hundred calories is a great place to start when aiming for weight loss. So what are you waiting for?!
