The HCG Diet can cause changes in your body’s metabolic process like any other dietary transition. As your body adjusts to the transition you might experience symptom like headaches. This typically occurs during the first few days of the P1 diet.
Just as you experience headaches from reducing sugar and caffeine intake, with HCG diet, you can experience similar symptoms. Your body expects to receive the same fuel it used to receive. In addition to that, the HCG in your body is forcing your stored fat into your bloodstream as a source of energy. So this is a different source of energy, as a result, you may experience a headache.
Fortunately, this doesn’t last very long. Most dieters experience a headache for 1-2 days of their HCG protocol. It is also common that those who experience a headache were on a high sugar diet on their gorging days. In this case, the headache is more of a metabolic detoxification from sugar rather than the HCG itself. If you are on the traditional diet, then probably you may just be protein deprived.
Understanding the changes can help you alleviate and minimize your headaches. There are few things that you can do about it.
