^that kinda intermittent eating pattern probably won't help you lose weight very efficiently, and most defintely not a healthy way of doing it, if anything you're more likely to put it on.
Anyone (except maybe guido - steroid king) eating 6-7 meals a day, needs to eat slightly bigger meals until you start to get that full feeling, making sure not to combine proteins with carbs (just veg) and vice versa, and then you will find this is giving you exactly what you need. You won't have to eat so often. I used to eat 5- 6 times a day, my metabolism is also fast, and when I'm working hard I get hungry yeah, but actually eating every 4 hours burns off fat and toxins a bit, just by waiting an extra hour or so - if you lose weight, trust me that's not weight you want.
Also I cannot stress enough for people with fast metabolisms the necessity of taking 20 minute power nap any day possible between 1 & 4, and also intermittent fasting - skipping breakfast on the days when you don't have much physical work to do, days off etc - I know it may seem like a long stretch to do it, the first couple of times you'll be so hungry it hurts - but it's very good for you, burning up toxins and slowing your metabolism by putting it into starvation mode(5 hours +).
Oh shit one last thing - no heavy workouts! (unless you're alright with dying 20 years too early) - our metabolisms aren't made for it, go for lighter exercises like astanga yoga, swimming, some martial arts, shit like that - isometrics and some plyometric exercises.
I personally now eat 4 meals per day, and have been putting on weight steadily, and muscle, without working really hard at it.
