Here is a study from Harvard that discusses the relative risks of eating a diet high in red meat, and offers the Mediterranean diet as a healthier alternative:

As a vegetarian for over 30 years, I never crave meat. Not even when I decided to become a vegetarian. What I have found to be the best way not to crave meat, is to find other foods, not just a few, but lots and lots of different foods to eat, that you like. Trying new foods is the only way to find out if you like other things. I have found out also, that it sometimes takes about 3 separate tries, of eating a new food before you acquire a taste for it.
And I can’t stipulate enough, how trying different methods of preparing and cooking things can make all the difference between not liking something, and loving it. Boiled, bitter, mushy Brussels sprouts is a far cry from this:

There are so many different ethnic cuisines, and so many different ways of preparing the same ingredient, take cauliflower as an example, that you could eat the same ingredient in 10 different ways and it would not taste the same, or have the same texture.
Variety, and knowledge about what you are eating, and where your food comes from goes a long way in making the connection between what you ultimately decide to put in your body.
For me, learning how to cook, opened up a multitude of culinary opportunities.
You don’t need to become a vegetarian, unless that is what you want. You should probably start with swapping out some things for the meat that you would normally eat. Also, make conscious decisions about what you are going to eat, and when. Make schedules. Meatless Monday is a thing, but you could make any day(s) meatless.
Have a menu, and a plan. It’s easier to stick to a menu, if you have a plan. A weekly plan, a monthly plan, a daily plan. Write it out, put alerts on your phone, start looking at meatless meal planning websites for recipes and inspiration.
Let your friends and family know what you are trying to accomplish. Some will be helpful and supportive. Some will be insulting and try to sabotage your efforts.
Before heading out to a restaurant, look at the menu online, or call the restaurant and ask some questions.
But mostly, don’t beat yourself up if you fall off the wagon, or fall short of your goal, or make a few missteps. All you have to do is start again, even if you have to start again multiple times.
Get rid of the meat in your home. Gift it to your friends and relatives. There is no sense in wasting it.
If you have any desire for recipes, just let me know.
