You do need to take care in having good diet, like taking care of protein intake, B12, omega-3. I personally prefer a flexitarian diet, where meat is rare, mostly vegetarian and vegan when I want to. Thing is, you don’t need meat every day, and just halving it makes a great difference already with minimum effect on your health.
