I absolutely cannot keep up with what we're supposed to eat? Some say low fat, some say high fat, some say high carb, low carb... no sugar, some sugar, some fats... It comes to a point where cutting one thing or another is surely futile. And that we just need to accept that there's no miracle other than eating a varied balanced diet, exercise and cut the fads. I know coming form a vegan that might be calling the kettle black (or whatever the phrase is) but I've given up on faddy diets, I just try to eat unprocessed shit and be done with it.
