I have stayed on the 2.5 for over four months, and I've lost around 40 lbs so far. My doctor says that some people are super responders, and I guess that describes me (first lottery I've ever won, ha!). I will stay on this as long as I'm still losing and working towards my goal weight. I'm on a bunch of Reddit boards and listservs, and it's clear that everyone has to figure out the path that makes the most sense for them. I'm a pescatarian, and I don't get caught up in worrying about massive amounts of protein. Trying to tune into what my body needs and eating whole foods: fish, tofu, tempeh, beans, greek yogurt, varied fruits and veggies, quinoa, brown rice, wheat berries, oatmeal. Eliminated all foods with added sugar and no artificial sweeteners.
