I can take excerpts from this but I don't really want to do too much of that as it is a short article and well worth the read.
Go read the article here.
I have written about Intermittent Fasting/Feeding many times before because I have seen it work for me, but especially for my husband, who sticks to the regimen with ease. He looks and feels great these days, what with IFing, low-carbing and gluten-free eating! It basically frees one from having to count carbs or calories or anything, but IFing done in conjunction with a gluten-free and low-carb diet is much more effective as cravings and hunger are held at bay. If one simply has to have something during the fasting window - then a cup of decaf tea or coffee with heavy cream might still those hunger pangs and if that's not enough, sometimes I "cheat" with a teaspoon of peanut butter and that really does the trick! However, if one can go without it's obviously more effective and gives the metabolism a full break from its work. Ian goes without except for coffee (maybe 2 cups in the morning), a drop of evaporated milk and a packet of Splenda.
