Some people do eat mostly meat everyday and they've been okay doing so but it's recommended that you don't eat only meat.
You also need vegetables and fruits in your diet as well to stay really healthy.
I only eat meat about 4 times per week although I love meat I just get sick of eating the meat everyday and just sometimes want some vegetables or fruits to eat instead.
Health professionals recommend you eat no more than 70 G of meat per day and if you eat more than 70 G of meat per day then you should cut back on eating the amount of meat.
Eating too much meat can cause you to gain more weight and increase your risk of heart disease and blood clots but meat in moderation is healthy and perfectly fine.
