I drink 500 calories and 42 grams of protein upon waking, and found that it increases my ability to fight urges to binge throughout the day. I'll often have another 500 calorie shot of Soylent around 4 o'clock so in a couple of hours when I have to decide on real dinner food, I'm in a good place to eat sensibly. I'm very excited at the trend of meal replacements, it's an indispensable tool in managing my addiction and I'm down 20lbs since January just as a side effect.
