answer:What I learned from my own weight loss and change in eating habits is that it was “what worked for me” and is not something I can tell someone else to do. Before a lifestyle change over two years ago, I would have considered the 7 or 21 day cleanse type trial. But I now know that those kinds of periodic challenges don’t work for me. So when I am asked about those types of things, I always reply, “if it works for you.” For instance, I have had to stop eating things that convert easily to sugar: breads, pastas, rice, potatoes, fruit juices. Part of that is because two years ago I had elevated blood glucose, and was advised that if I persisted I would be considered “pre-diabetic” and would be diabetic within five years, and most likely sooner. But my girlfriend tends to be hypo-glycemic, and needs to eat carbs occasionally during the day, and also have some orange juice in the morning. So we are like the sugar version of Jack Sprat and his wife.
