Yes. I can digest both. I went on an 11 day camping trip in late September and had both. I also eat a more regular diet when I’m with my family. My medical conditions begin to return and I put on weight steadily but I’m able to eat the food and enjoy it for a few days.
In fact, it’s my preference to maintain a bit of digestive flexibility this way. The trick is to start small if you haven’t had plants for a while. I usually start with a bit of fruit. That always seems fine.
On my camping trip I ate small amounts of nuts and seeds (2 tblsps/day approx), sauces with vegetable bases (tomato, onions, etc), coconut oil in my coffee, ghee with my fish and meat dishes, and a fair bit of cheddar cheese on various dishes. None of this was any issue. In fact I felt wonderful.
One thing that was interesting was at the start of the trip my intention had been to also include 100% cocoa powder in my coffee twice a day. But the first day I felt lousy (my abdominal pain flared) and it seemed to coincide very tightly to when I drank that drink. So I cut it out and the rest of the trip went perfectly. So, I think I’ve identified cocoa as a major evil for my system.
Have you seen my beef binge buster thread? It’s a protocol that gives me extremely rapid weight loss and craving control without any fasting or caloric restriction. I use it now anytime I want to lose a few pounds or I start to feel less well again. It always fixes me up.
Basically, the diet is just extremely fatty beef, extra beef fat, bone broth, salt, and water. I lose about 1/2 a day every single day when I do this even when I’m already under 110 lbs.
