3. Diet Soda

We are already aware that regular soda is one of the worst drinks to be consumed. This is the reason we swap full-fledged sodas with a diet soda. But alas, diet soda too is no good. It may be calorie free but it is unhealthy for sure, because of the artificial sweeteners that not only increase the sugar content but also escalate the growth of bad bacteria in the gut. When the body reacts with the artificial sweeteners, the blood sugar level also increases, which ultimately leads to weight gain. So, go for a fresh juice instead!
