The first week was the hardest--after that I got used to it.
One thing I didn't truly realize until the Hacker's Diet is how much socializing in American culture revolves around consuming high-calorie food products when you're not hungry. Going to the movies? Of course you're going to get a tub of popcorn, soaked in butter. Sitting at a desk at work? Of course you're going to have a bag of chips there beside you, and near the end of your workday you're obviously entitled to a Milky Way bar to get you through that last hour or so. Going out to a pub with friends? Of course you'll get a basket of fries and onion rings, maybe even a burger, even though it's midnight. Going out for lunch? Of course you'll go to the all-you-can-eat buffet, where you can get your money's worth.
Giving up the socialized high-calorie eating (especially in the face of continual peer pressure from friends and co-workers) was the hard part for me, not doing the math with the calorie count.
You'd think it'd be easier to diet in Japan, but it's actually very difficult. Food goes bad here really quickly, so you have to eat your fresh food within a couple of days. That, coupled with the fact that a lot of Japanese food is not healthy (contrary to popular belief; sushi is great, but there's a whole list of J-food that's swimming in calories, like katsudon, anything yaki, ramen etc, etc,), and unless you have a Japanese mama cooking your lunch and dinners for you, you're not going to get healthy meals unless you make them yourself.
And a low-carb diet? Fuggedaboutit. It's all rice and noodles over here. Japanese people look at you like you've got a penis growing out of your forehead when you say you eat toast for breakfast. Pfft. Like a bowl of rice every morning isn't the exact same thing.
When it comes down to it, socialization in most cultures revolves around eating. Izakayas, Japanese restaurant/bars are the perfect example. Going out with your friends on the weekends makes it incredibly hard to stay focused, and you look like a party pooper when you don't drink and hardly touch your favorite foods.
Living in Japan has driven home the fact that it's the exercise that keeps you healthy, because Japanese people eat a ton of nasty, unhealthy shit- just like Americans. And Jesus Christ, the Japanese smoke like fvcking stacks. The thing is, most Japanese people are involved in some kind of activity to keep them healthy. Sports, judo, kyudo, kendo, kempo, jogging, soccer, rugby, you name it. It's cool to live in a place where most people look at activity and exercise in a positive light. That's why I started kyudo.
