No. No. No. Carbs and high sugar foods (since carbs are effectively sugar) give your body a boost after eating (since sugar = energy) and then your body goes into a sugar low and feels tired. It is NOTHING about fasting, it is about the cutting out of sugary foods and replacing them with natural sugars from fruit and more protein that is giving you the energy. Likewise, your Insulin levels are being kept in check by the reduction of carb and sugars, NOT because you are fasting.
edit - and people "back in the day" did not fast because they wanted to be healthy, it was because they didn't have a choice |
