The easiest to understand: Practicing vegetarianism means abstaining from the consumption of all kinds of meat (red meat, poultry, seafood, and the flesh of any other animal).
The reasons behind it might be related to animal slaughter or just to lead a healthier way of life.
Variations of the diet include ovo-lacto vegetarian (which allows both eggs and dairy products), ovo-vegetarian (only eggs), and lacto-vegetarian (only dairy products but not eggs).
Also known in French as végétalien (a pretty cool name), vegans not only stay away from meat but from all products with animal source.
Strongly attached to animal slaughter rejection, veganism usually means love for all animals. That’s why some of them also avoid other products such as beeswax, and leather or silk clothing.
A freegan’s goal is to reduce food waste, which means they don’t stay away from all animal products.
Sometimes they might eat them, for example to honor cultural traditions (like Thanksgiving).
Freeganism consists on feeding on anything that you come across or find available without letting it go to waste.
For those who just can’t abandon meat entirely.
If you’re not ready to commit to a full-on vegetarian lifestyle but do want to reduce your meat consumption, this diet is for you. This is similar to freeganism but flexitarianism isn’t related to food waste.
The term emerged in the late 90s to describe people who are largely vegetarian but still occasionally consume meat and other animal products.
