The concept of alkaline diet is based on the fact that human body has balanced mix of alkaline and acid. But the wrong and unhealthy foods such as junk food, alcohol, salt, coffee etc., which are basically acid forming foods create an imbalance in your body by producing more acids, which further causes stress and increase in body weight. Alkaline food items bring back the balance between the two and assist your body in scorching surplus calories and boosting up energy.
