if anybody else wants to give it a try...
for less excess kcals, use one packet of fat free/no sugar added pudding mix with 4-5 scoops of protein powder, using an electric mixture with only a little bit of water (maybe less than a half cup? i usually start off with as little as possible and add a little more if needed). it will seem real thick and chunky at first, but just keep mixing. eventually, it will get smooth, but remain thick. refrigerate it for a while (~hour). then you can eat half of it mixed with some fat free cool whip. i like chocolate with the cool whip, but you could use whatever kind you like i guess. it tastes good to me. the only problem i have is that it's not real filling.
