| Flilix said: I've had underweight problems in the past, even though I eat quite a lot. Sure, I could just eat a lot more fruit and vegtables, but I already eat a lot more of these than most people (and my weight is still pretty low). |
This is an interesting one. I know people who eat huge amounts of calorie dense foods (meat, dairy, eggs, junk food, etc.) and are underweight. And I know people who eat mostly whole plant foods but struggle to maintain their weight. But those are all anecdotal. Where it gets more interesting is when you look at populations as that smoothes out the exceptions to the rule.
When you look at populations vegans typically average in the ideal BMI, vegetarians are a little overweight on average, and omnivores are a lot overweight on average. BMI is a largely useless tool when looking at an individual, but is very useful for analyzing populations.
