what people are "on" about is that you say you're kind of following pb, but that you're not really, and it's not "working".
so re-read the book, look through the wealth of info mark gives on here, for free, and actually do the pb. commit, for at least 30 days. eat clean, move around, get proper sleep, etc. it's all of a piece.
for those looking at this to be a quick fix diet, well, in a few weeks or months, they'll be on to something else, complaining that this doesn't"work". just like the bajillion other "diets" they have tried.
500-1000 cals, and very low protein, and you're body is probably cannibalizing muscles and keeping its fat stores for a real emergency, which is why you remain a "little blob". you're not exercising, so not burning glucose or fat, nor building muscles.
i'm not sure why increasing calories to you equates increasing krap carbs? veggie calories are very low, and even mountains of greens are low in carbs. you need more protein and more real food.
btw, i never liked meat as a child. as soon as i moved out i became a "vegetarian". grain- and fruit-itarian more like. even though i was always sick, i thought that was "normal". it took many years to catch up with me for real, but when i hit 42, it sure did. after cutting out grains and junky carbs, there are plenty of days now where i crave meat or liver, and i know i must need it.
