Concentrate on eating only fatty cuts of meat and salads (with blue cheese dressing for extra fat). If you really want a vegetable, eat broccoli and cauliflower. Remember–no sugar, starches, or grains, and you’ll be all right.
Get your energy from fat, instead of carbohydrates. If you need a snack, eat some pork rinds, buttered chees, or pepperoni, then eat more at the next meal. If you are eating enough at meals, then snacking becomes more a matter of emotional eating than need.
The ethical and moral considerations involved in vegetarian and vegan eating are not as clear-cut as people would have you believe. The truth is that all food production involves killing animals, and who’s to say that the life of a beef animal is more important than the lives of all those small mammals, birds, and insects that are displaced or outright killed by farming crops?
The environmental considerations are even easier to deal with: proper regenerative farming methods restore the soil, rather than depleting it. Eliminating commercial fertilisers and pesticides by adopting proper adaptive multi-paddock grazing saves an enormous amount of fossil fuels and sequesters a surprisingly large amount of carbon. The increased permeability of healthy soil reduces flooding and allows grasslands to survive and even thrive during drought years.
Furthermore, there is not enough cropland on earth to feed everyone (and we’ve built cities on a lot of it, which doesn’t help). Most agricultural land is suitable only for grazing, so if we are to have a hope of feeding the world, it will have to be with animal foods.
Sorry for the rant, but the picture is not as simple as a lot of people make it out to be.
