Mine was more white collar, where I commuted in Los Angeles traffic for 2 hours each way, and managed a team of high stress, high reward investment consultants throughout the day, while managing the private fund of a group of our highest net worth clients. Eating throughout the day was not a problem, but I was already waking up at 4 to get to my office by the time the market settled a bit after opening at 6 am (9am new york time). I would get home around 8 pm, exhausted. Barely enough time to workout quickly, eat, and sleep to do it all again the next day...It taught me a thing or two about self-discipline lol... no pain no gain bros.
