I like Kursgezagt take on the whole thing. If you can go full vegan or vegetarian then go on, if not just reduce the intake of meat and treat eating meat with the respect the animals that suffer deserve for you to have it in your plate with the type of horrible conditions they have to be and the effects it causes to the everything. Don't indulge yourself in it like it's a faire or "free" for the planet and the economy to afford your disproportionate luxury.
Humans are omnivores, there's no denying that. Maybe there was a time where they didn't had to but for you to be ok and healthy and live more, have good defenses and all you have to eat meat. Even vegans have to take pills and substitutes to compensate for the meat they don't eat. So It's not bad if you eat it but just do it sparingly and adequately. Prefer veggies and legumes or cereals during the week, eat chicken or fish twice or thrice during that time, and on saturday or sunday you can eat one small piece of red meat, if not then every two weekends.
I'm trying to do so myself. I do like meat though try not to eat as much but my family is pretty much carnivores, they are kinda huge so to speak, so it's difficult for me to actually do a diet or balance of any sort because in the fridge is the only thing you can find or they simply buy things for me and guilt trip me into eating it, adding the pandemic where I can't go outside and my job that hasn't stopped at all I can't go buy my stuff or do exercise to burn the excess like I used to.
