Maccas, or McDonald's for those non-slack tongued people, in the UK blames the obesity epidemic on games instead of its food. *Checks himself*
Well, I'm checking my arse to see if it is inflated or something in which ghetto talk calls it, a booty. And nope, nice and non-invasive with no problems getting into my snug jeans. I love my games and can play it for half a day straight without losing my focus and improve my eye-sight. (I tested my eyes for my hand to eye coordination and it is pretty darn high in score!) And am I fat now? For the interest of saving time and effort into detail compiling absolutely nothing, a big fat No.
Even though it is old new to some, we have ourselves someone who isn't a gamer, but someone high up in the corporations with a questionable "clean" identity lashing out on an entertainment which can improve eye sight (FPS), thinking skills (Strategies), the body (Wii & Wii Fit obviously) and one which can cause people to go anorexic in the extreme sense (*cough* World of Warcraft *cough*), and hey, they last point doesn't make people fat, just skinny and fall over, but main point, "Not Fat!"
I can pretty much tell you that in order to be a good gamer and reach a high level of competitiveness, you'll only have to look as far as the CPL or CAL (Cyberathlete Professional League and Cyberathlete Amateur League) and how many large people do you spot? According to Maccas, it should be everyone because games are suppose to make people fat. But, how do games make people fat? Where's the protein value in consuming their vital game DVDs? It is more likely to kill you instead of providing you with all the metal concentrates in your body (I do not advise actually trying this to prove my point or someone else's). Fast Foods consumed by gamers? Well, according to Leeroy Jenkins, he enjoys his chicken very much, but he ain't fat, and neither is his dwarf.
Maybe it is gamers being lazy cooks, yet, Leeroy Jenkins roasts his chicken and does silly rushes (if you have no idea about who Leeroy Jenkins is, please chuck a Googly), but hell, he is healthy, living well and is loving his chicken but if you are willing to blame it on poor diets of gamers... well the check alternative to actually running to the nearest Fast Food joint and ordering everything on the menu, the crazy, yet quick method is quite simply a carton of milk with breakfast cereal. Sounds stupid, yet if you think about it; for one, food in a fast; for two, it provides you with all your essential vitamins and minerals for living; for three, one run and it will last you at least two days when you are hungry; for four, it lasts a long time; and for five, it is actually easier for the environment than having a bad diet of fast food, don't forget about the cost too! Definately costs less than your local Fast Food chain would, but hell, have ten different cereals with at least twenty cartons of long life milk in the fridge and you've got yourself a sweet, long lasting supply of food to last you a good month of gaming non-stop! And would you either get fat and die or being totally anorexic? Fat, depends on how fast you are consuming it, becoming rexic, doubt it unless you are eating less than 3 standard bowls a day.
I don't personally endorse any of those activities or part-take that, but I live on a healthy diet with plenty of sunshine, sports and gym, so I'm quiet a healthy and happy gamer and was kinda on the obese side thanks to Maccas and their long-standing advertisements to the youth and teens viewing their commercials.
After learning from the mistakes of the past, it honestly comes down to the individual and the kind of eating and living patterns, but still, Fast Food doesn't help in the health agenda of gaming, but the pricier joints actually provide a nice healthy outlook for gamers, even with the steep price.
In Closing, if you are to become a gaming hermit, don't forget your boxes of cereal with a fridge for storing nice and cold milk for your eating needs without having a two minute lunch run (I don't recommend performing excessive game hording, but this would be a better alternative for everyone's sakes, consider your family!) than a fast food run with a hint of lard and/or fatty oils in your diet (even though fat is needed in your body, fresh milk has enough of that, check the long life ones if they do) and better than pure starvation.

Just for those questioning if I play any game obsessively, right now, the answer is no; with "No" WoW account as I never even considered touching it as I am too cheap for that; too much uni work for a Team Fortress 2 (and yes, I love that game) hording sessions; I need to reformat my computer as a virus has gotten through again (don't tell me which Anti-virus to get); I've got my Bachelor of Computer Games (yes, that's exactly what I doing) course to worry about and I've got exams in less than 2 weeks. After that, this gaming computer can't come to me and I am living a more happier life away from gaming, but it doesn't mean that I've stopped gaming.
