Until today, I hadn't heard about "Fasting Mimicking Diets" (FMDs). But now, I'm intrigued by the apparently new research that fasting can prevent mast cell degranulation (the process that releases histamine into the blood stream from mast cells). Perhaps this is why I feel better, at least initially, when I don't eat for a few days. Of course, that isn't an option, long-term. FMDs allow 725 to 1100 calories daily, offering the correct breakdown of macro and micronutrients needed to convince the body it's starving. It offers the benefits of water fasting, but with less stress to the body. For now, the diet requires food replacement products that are only available for sale through the website of the doctor that developed the plan. Perhaps more will be known in the future, allowing patients to develop a "do-it-yourself" FMD. Here's a link to a description of FMDs: http://healinghistamine.com/fasting-mimicking-diet-for-mast-cells-and-histamine/ Any thoughts?
