Another strong advocate for DDF. It's a way to expose what's going on with anyone who stalls and stays at a plateau despite eating very few carbs. Energy consumption in the form of carbs and most likely fat in a low carb WOE may undermine even the most consistent low carber's attempts to achieve an ideal weight. For us low carbers, fat is often emphasized in many approaches and consumption of fat over carbs has been recommended. However, there is an individual limit, and that's what DDF can help people discover. The answer is often replacing some of the fat with protein and low carb vegetables. Good stuff.
