Hey, Jeff. I merged the two threads, because the topics are basically the same.
As people have pointed out, a ketogenic diet is primarily about restoring metabolic health, with fat loss, if one has extra stored fat, as a desirable side effect.
The first thing to bear in mind is that fat loss is not a linear process. It happens in fits and starts. The primary requirement is to keep your insulin level low enough to permit fatty acids to be released from your fat tissue, and you do that by eating as little carbohydrate as you can manage, since carbohydrate has a significant effect on insulin secretion.
The second thing to bear in mind is that the body will hang on to its fat reserve in times of famine, and the signal that there is a famine going on is a reduction in caloric intake. So, paradoxically, the way to convince the body to let go of excess fat is to give it enough calories. We need a certain amount of protein every day, so the effect of protein on insulin is always going to be there, but fat has almost zero effect on insulin secretion, which makes it the idea source of calories to replace those lost by cutting out carbohydrate. So yes, eat fat in order to lose fat! Who knew? The easiest way to make sure you are getting enough food is to eat to satisfy your hunger: eat when hungry, stop eating when no longer hungry, and don’t eat again till hungry again.
The last thing to bear in mind is that those amazing stories of fat loss on a ketogenic diet come from people who had lots to lose. The closer we get to a normal body composition, the more slowly fat comes off. There is also the possibility that giving your body abundant nutrition will cause it to add some muscle and increase the density of your bones. These great effects can confuse the scale, so keep track of your fat loss by measuring your waist line, as well as by weighing yourself.
