Shooting from the hip, yet having my trusty long long bore near by I'll give this a try. I have a view of 'fasting' having a different connotation than weight loss. Even though there may be prudence with diet I would caution undertakers of the consequences, which are both good or bad, on different realms - mental, emotional, and spiritual.
I have read many diets and even partaken of one regarding fasting for the purpose of detoxing with French Green Clay as the catalyst. The continuance of the use of French Green Clay for that detoxing purpose for me lasted maybe two months. Then happenstance occurred. Maybe the next attempt I will succeed.
Yet that does not answer your question. Being diabetic I would also take caution while remembering carbohydrates are the main theme with that type of diet. I would attempt this style of weight loss by taking the time to do some figuring how many calories for the four meals a day with 45 - 60 carbs per meal and 15 - 20 carbs for snacks. I'll be darned if I do that from day-to-day too - giggle.
Thank for the question. I do like the articles I saw at your profile. Congrats on being an apprentice. If you meet Merlin, please share of that experience - giggle . . .
