If you have something that works then stick with it until it doesn't!
As for me I'm mostly plant based, but hate the V word and refuse to live under a label. If there's an Imu or someone catches some local fish then I'm all over it, but that's kind of rare and I'm definitely not seeking it out.
Last year I had multiple surgeries and went back on the Kualoa beef to help recover, but as of last month switched back to mostly plants. The number one reason is most of the meat here is terrible quality and full of factory farm poisons and antibiotics. I get a variety of different proteins from beans, hemp seeds, and leafy greens. The combinations of proteins keeps me satisfied, but obviously not easy to find in the land of the plate lunch. Also a challenge is not eating cookies and rice all day since I also have to limit carbs so I don't blow up like a balloon. A lot of the pre-packaged V-friendly stuff at the store is just salt, sugar, and carbs dressed up in yuppie marketing.
The benefits are more energy and a clear head. The only downside is the inconvenience, but that can be mitigated. It really pushes my limits as a cook and despite a few screw ups my kitchen game has really improved, and it's made me a better gardener as well.
