I'm a more version of paleo. Only white meat and no fruit

As long as you maintain a diet above 800 calories to avoid extra cholestorol building in the gallbladder, you can eat whatever time you want. Skip dinner. Breakfast and lunch are fine.

I've been paleo for quite some time now, and initially it's a bit of an adjustment. It took me about a month to start feeling acclimated to eating this way. I think the reason it took so long for me to even feel kind of okay was due to several chronic health issues that have since sorted themselves out. Don't worry too much about it if you don't feel 100% awesome all the time if you're just switching over. The other suggestions on here seemed pretty sound regarding you feeling a bit sick after meals. All in all, just give it some time and listen to your body :)

Idk about your sickness, but my dad lost eighty pounds on Paleo.
