I was a complete vegetarian (no meat, no gelatine, no fish) between the ages of 11 and 19 and was slightly overweight before the age of 18; I'm 5 foot 1 and weighed 10 stone and 5 pounds at my heaviest point. This is partially because veggies will often have to turn to pasta, cheese and creamy rice dishes when they eat out. I also managed to turn to these foods at home... I wasn't the best informed child when it came to nutrition. However, I was rarely unwell and I did have muscle too.Humans eat meat cause it helps our immune system and also feeds our muscles... if you look at a vegetarian they are very skinny and have lots of health problems... this is because of the lack of meat in their diet
Now, I'm a pescatarian. I will eat fish but refuse to eat meat and any substance that required killing the animal. I actually drink soya milk now, due to the process cows go through when milk is produced, and we have our own hens so I can eat their eggs without any cockerals being killed. I do, however, eat yogurt and chocolate, the former for health reasons since yogurt provides important bacteria and calcium.
I still have some fat on my thighs from when I was overweight, but overall I have a healthy amount of muscle. I actually have more muscle on my calves than all of my friends and even my boyfriend.All of them eat meat. None of them, however, exercise as frequently as I do. My family have been walkers for well over 21 years so I grew up walking. I now walk a couple of times a week for 1 - 3 hours each time. I will go more often if I have the time. I also can't remember the last time I was ill! I don't think I've ever had the flu, I have had perhaps one cold in the last year, I've had food poisoning once in 21 years (after eating out where there was seafood), I don't often get headaches, I've never had aneamia... My blood pressure is also the best it can be according to the doctor.
Oh yeah, and I'm certainly not overweight anymore. Nor am I underweight. I weigh 8 stone and a half. Basically, I replaced the pasta, cheese, rice and pizzas with something more balanced. I eat A LOT of vegetables and fruit, pulses, fish 2 - 3 times a week (as recommended), eggs, oats, yogurt... On this diet, I've actually gained weight since Uni (some of which is muscle), where all I did was eat less. I'm certainly not wasting away.
