Low-carbs does not mean low food consumption. When taking part in a low-carb diet you can suffer some side effects such as headaches, bad breath and cramping. It is important to remember to eat regularly when you are hungry. Snacking on nuts and other healthy treats can help with these issues. Eat natural fats like avocado which your body uses to burn energy. Eating real protein as opposed diet bars will allow your body to feel healthy and fueled throughout the day.
