Yeah intuitive eating is a fucking disaster for the already overweight. Energy availability (are you starving) is regulated by how often the brain is getting battered by a hormone called leptin. It's secreted by fat cells. Makes sense right? Fat tissue is the reserve of energy for the body to do stuff (because if you break down fat you can power the muscles/heart off of it and you can break down muscle protein and convert it to glucose via the liver for the brain...heart/brain have some very strong preferences for what energy substrate the work off)....now, the more fat you have, the more leptin eventually makes it way to your brain. Eventually the brain adjusts to the elevated levels of leptin as the new 'normal' and then when weight loss occurs and less fat derived leptin is hitting it there's a perception of not having enough energy or the often touted 'starvation mode'. Sadly it's the fate of the fatty or reformed fatty that they need to keep a food diary/track calories/weigh in more consistently/diligently than someone who never got fat in the first place.
