Btw I hope that in the long term lab grown meat will make this less of a problem.
Ethics aside, you can do compensatory actions in another area. Tree planting, habitat rehabilitation, eschew car ownership and take the bus/bike/walk, invest in renewables, donate to or volunteer at environmental charities, volunteer etc. To be effective, I guess link your meat consumption to your compensation. Eg: every 1kg of steak donate $2, or 10kg plant a tree, or whatever ...
You also aren't obliged to eat meat all the time. Why not just twice a week?

For all others: Please go ahead and downvote this comment. You're not a lion hunting prey for food. You're just a guy buying a dead animal at a store.
As for your original question, I became a vegetarian 5 years ago and it's only had a positive impact on my health.

Have you tried the Mediterranean diet?
The most ethical diet that includes meat, in my opinion, is eating mostly plants and then hunting your own meat. Most people also don’t need nearly as much meat as they think they do. 1-2 servings per week could be sufficient - which could be easily covered by fishing or hunting a few times per year and then freezing.
Ethics: the best I can say is "that's cultural", and often personal. We're all doing whatever we want, and sometimes our values align enough to get along for a long time. I ate a lot of meat for about a year (or so; I didn't keep a log) and then stopped for a couple reasons, including environmental impact. I grew up on a farm, I've butchered animals and eaten them, I've hunted, and I see every living creature as an individual person worthy of respect. And still I kill them. If we were more honest about this when we go to war I think we'd be better off, rather than all the othering and dehumanizing that is so effective.[1]
My internet-stranger advice would be to practice going without food for longer and longer (it took me about two months to go past the ~48 hours when autophagy starts; I paced myself so I could keep an even keel at work (parenting/homemaking)), and then break your fast with an amazing meal, starting with foods high in fiber (something about how the food progresses through the intestines, and absorbing nutrients, and not spiking insulin), and including whatever you want (I only want high-quality, healthy food for these meals, maybe ending with more carbohydrates at the end). Meat seems like a reasonable inclusion if eating fewer meals. Fasting and feasting is different than calorie restriction; the former I find empowering and self-respecting, the latter I found torturous.
In any case, I hope you figure it out, and good luck!

If you also care about animal suffering, some foods have much more impact than others, see e.g. https://thinkbynumbers.org/utilitarianism/direct-suffering-c...
If you really want to see change politicians need to do the work, not you.
The carbon footprint of eating meat is a thing, but I don't know... doesn't have the ring of importance.
If you think you can treat an autoimmune disorder by eating a lot of meat, then why not try it? Just bear in mind that it is in other ways harmful to your health compared to vegetarianism [citation needed].

This has been excellent for my own health. I'm working my way through a grass fed cow I bought from a local rancher. It's quite pleasant work. In a year and a half of carnivory I've lost 75 excess pounds, all of my diabetes symptoms, and several inflammatory complaints.
Nutritionally, it's been shown again and again that plant based diets are healthier than meat eating diets. And not just that, but there is actual science to back this up. Compare the science for plant based diets (https://www.reddit.com/r/vegan/wiki/veganscience/) to the basically non-existent studies regarding human carnivore diets.
I'd highly recommend having a start here for some general resources: https://www.reddit.com/r/vegan/wiki/index/
It's better for yourself, the planet, and the animals to be open to going down this route. Don't buy into the weird unscientific propoganda from the carnivore club, look at the research, and question why you're concerned about the ethics of meat eating to begin with and maybe explore that to the fullest extent.
