I've recently cut down on the rubbish food I eat, and only stick to three main meals a day - usually. I use to snack throughout the day, and although I didn't gain much weight, I saw myself slowly getting bigger. By snacking, I meant main meals throughout the day which obviously isn't good for me (6 main meals vs. 3 - I must add that I was walking with a substantial weight on my back for hours every day and gigging most evenings which cut down how much the food could have effected me had I been sitting down and doing nothing). I honestly think it's a stupid thing to not eat, because: 1) As mentioned before, it's fuel for your body - no fuel no go. 2) Your overall health declines at a crazy pace - one of my uni mates never has much money for food, but drinks water and milk a lot. Although it's not as good, it seems to keep him in a decent state. He's now realized he can eat bread throughout the day. Before realizing this, his health was appalling, and he couldn't concentrate in any classes, and found it hard to talk. 3) Your mental state declines at a substantial rate too - I get grumpy as f**k when I don't eat, so I can't imagine what it'd be like after a couple of weeks. This is my opinion though, and because of the fact that I love food I couldn't imagine someone not eating. None of my family have been in the position where they haven't eaten - as far as I know. I've gone through rough patches where I haven't had much food to eat - but I always found a nutritious substitute to make sure my health didn't plummet because of it. I think I went a bit off subject in this post, and quite possibly contradicted myself, but oh well!
