Congratulations on your weight loss! What you eat, when you eat, how often you eat, how much you eat, Protein - all critically important to your success. How fast you eat is something to consider and work on but not as important as these other factors (in my opinion :-) You can Google "tips for eating slower" and find lots and lots of suggestions for helping you slow down including information on "MyFitnessPal" and "WebMD".
When I made my decision to go with RNY, I was convinced beyond any shadow of a doubt that if I followed the protocol, to the letter, it would be medically and scientifically impossible for me not to lose weight. To this day, absolutely nothing has happened to change my thinking. "All for nothing" - simply not possible if you follow the protocol. Is it "easy"? No. Is it "easier"? Beyond any shadow of a doubt. As you've already seen from responses to your post, not everyone is full after two bites. I would go even further and say that the whole journey is different for everyone in many respects. You'll get tons and tons and tons of great ideas from all the great folks on this forum. But as you try different things, always remember that, as they say, "your results may vary". All that means is experiment, try new ideas, find what works best for you and it will take you to where you want to be! Stay focused on following the protocol. Stay active. Stay away from the scales. You're gonna love the new you!!
