@SaraKim17, I fully get your disquiet regarding the eating of meat. With the very greatest respect to both your doctor, and @Sunny_Bunny_, comparing our habits to those of snakes and cats, is comparing Apples to Oranges; quite simply, snakes and cats are natural carnivores (although arguably, predators of this kind also take in vegetable matter when they consume every bit of their prey - which more often than not, is a herbivore).
I used to keep snakes; I have also had cats and dogs, and know that feeding my dogs a BARF diet was of great benefit to them. No snake I have ever come across would eat a vegetable. (In the UK, it's illegal to feed live food; so rats, mice, chicks and even rabbits have to be purchased ready killed and frozen. They must be completely thawed and brought up to room temperature before being fed to snakes. I had a snake that refused chicks; another wouldn't touch mice, but was voraciously fond of rats. So even those creatures considered basic and unintelligent, have 'tastes'.)

Humans are different. We have through the millennia, eaten both meat and vegetables. Isn't the Paleo Diet an example of (pardon the pun) going back to our roots?
The dilemma regarding eating meat, therefore, is an entirely moral one (unless there is, of course, a medical condition saying otherwise).
I too, carry this dilemma with me.
I am Buddhist. An awful lot of people say to me, "I thought Buddhists were supposed to be vegetarian?"
The answer is, 'that depends'.
it depends on which School/Tradition of Buddhism you follow, how closely you follow it, and what your own conclusions on the matter, are.
I eat meat.
I used to eat chicken, and fish, mainly, on the basis that chickens are specifically reared for eventual consumption, being the most common bird in the world, and fish is still the only creature which is hunted, and has therefore an even chance of evading capture.
I began eating meat in much larger and varied quantities, ever since I began this LCHF/P regimen.
My School/Tradition of Buddhism holds this teaching: You may eat meat, providing you personally have not caused its death, nor have you specifically instructed or requested any other person to kill, for you or on your behalf.

(There are some meats which are expressedly forbidden: that of humans, elephants, horses, dogs, snakes, lions, tigers, leopards, bears and hyenas. This is because these animals can be provoked to violent anger by the sight/smell of the flesh of their own kind, or because eating of such flesh would generate a bad reputation for the Sangha (Buddhist Community).)

So I'm alright then. I have never killed an animal to eat it, and I've never asked anyone to do any such thing for me. So that's ok, right?

No. Not quite.
The moral niggle still swims at the back of my head.
My personal problem is that I like meat. I love it. Always have done. I have eclectic tastes which go all the way back to my youth. I'm Italian, and grew up in an environment which took meat as a matter of course. I ate offal and all manner of dishes prepared by my grandmother, aunts and parents.

I became vegetarian when I decided to take up Buddhism as my calling.
I stuck to it for at least 15 years, with only the odd occasional 'lapse' depending on where I was, with whom and what the occasion.
But I missed it.
So I gradually introduced chicken and fish into my diet, on the premises given above.

I hate to tell you, but if you eat meat, much as it will benefit you, do you good, and prove enjoyable, in my personal opinion, I don't think you'll ever completely rid yourself of the Moral aspect.
I'm constantly on the horns of a dilemma. I try to 'buy responsibly'. But organic, hand-reared, grass-fed, 'acceptable' meat is very expensive, so sometimes, the supermarket is the only option.
When we go against our own morals, when we fly against that which we suspect to be correct, there is always a twinge, a pull.
I have no answer for you.
If others choose to label me a hypocrite, then that is their right, but I will not defend myself to them. I am answerable to myself, not to them. It is me, I must live with.
And I can do that.

Eat meat. Let go the guilt. But never lose your Moral stance, for thereby character is cultivated.

Just a thought to help with eating the egg..... I have chickens (no rooster, just hens) they will lay an egg almost every day. The chickens are pets, well cared for, fed organically and even have names. The eggs are not fertile because there is no rooster, so no animal is being harmed by eating the eggs. They will lay them whether we eat them or not. Its just what they do.

I have a few friends who sell eggs and if you are buying cage-free, organic eggs from a farmers market, you are likely getting high quality eggs from well treated and loved chickens.
