Vegetarian since I was 14, now it's 5 and a half years later; started cycling two years ago. I became a vegetarian originally for ethical purposes and under the understanding that humans are much closer to herbivores than anything else. I continue being one for the same reasons and because I've been incredibly healthy; I do yearly full blood-work analysis because of hypothyroidism.
My cholesterol is 92, and if I had to guess my body fat then I'd say it's the lowest it has ever been at around 4-6%.
However, I don't watch how much eggs/dairy I eat. I try not to eat eggs by themselves too often, or have milk as a beverage, don't enjoy it.
