I would recommend nit-picking your standard meals. Why don't you provide some details of your specific diet, exercise, and some statistics and we may be able to better help you out. Also, you may be eating exactly what you need to eat but not at the right time. I had a slow down because I kept waiting way too long to eat lunch after breakfast, I reduced the size of my meals and threw in a mini-meal to have 4 meals and it seemed to have worked. At approximately the same amount, outcome way different.
I believe the "eat more" suggestions apply mostly to those with a more active lifestyle, or those employing the exercise parts of 4HB. If you have a completely sedentary lifestyle and arent losing any weight, you might want to eat less, but introducing even just a small amount of exercise will render a much better outcome (increasing your BMR, building muscle to burn fat, etc). As long as the exercise isn't so strenuous for you that you eat cheat foods, you shouldn't cut down on what you eat. For the aforementioned reason, you should ease into an exercise routine if you choose to involve yourself in one. The longer you are on SCD, the more tempered your hunger will be (because it is actually a different kind of hunger than one induced by complex carbs, IIRC this is called toxic hunger). After this happens, the amount of exercise you get will perfectly dictate your hunger. If you eat slow enough at this point (*this is important), your body will feel full when it doesn't need any more nutrients in your blood. This is why Tim says "Eat as much of the approved foods as you want".
Hope this helps, I'll check in again if you want some help with the specifics 
Thank you gretchenlin, that's exactly the answer I was looking for. The video is great! Everything makes much more sense now.
