Hello everyone.
I have been a healthy weight from the get go. Well, I probably can stand to lose a few pounds but I'm not worried. Well, I recently cut out processed foods and my weight is starting to dip down. I can tell because I can feel the ribs in my chest.

(And, just for an argument for not sitting all day, my butt is the only place that still has any fat

)
Anyways, cutting out the sugar and almond milk has really helped my IBS, but I do not want to become underweight. Plus, I'm only eating about 1500 calories a day. I do eat until I'm full.
So, my question is, what healthy things should I add in to maintain a healthy weight? Nuts and seeds aren't the greatest since they upset my IBS (It can be a pain in the you-know-what, quite literally!).
I think I know the answer, but I have been curious about what Star McDougallers do and have wanted to ask for a while.
Normally I eat lots of brown rice, beans, veggies, 2 peices of fruit if I feel like it, and the odd "bread" product that's gluten-free.
I want to maintain while being able to keep a moderate exercise routine.
Thanks, and this forum is a great idea!
