Calories are the finances of the body!
When you are looking to either lose or gain weight one of the best places to start is by looking at you calorie intake. Tracking your cals and consistently hitting a cal target is where you are going to see the most success in weight loss/gain. Being in control of your nutrition is more important than choosing whether to eat white or brown bread. Start keeping a food diary, or download the myfitnesspal app and stop guessing how many cals you are eating per day.
