Keto is great but there's still a willpower component, it can be more or less difficult depending on the person. I don't really like cooking a lot, but I don't mind eating the same things most of the time. It would be a lot harder for someone who hates cooking and hates eating the same thing all the time. While raw hunger never bothered me I did find cravings an occasional issue (never constant, but even after months never quite disappearing) and sometimes they'd be for things I haven't had in years. Eventually it might be something easy to satisfy like a pizza and when you give in once it's easy to say "screw it", though some people can only continue if they have an occasional cheat day.
I'm an on-and-off-again keto dieter (I appreciate that for me it seems to take at least 2-3x as long to put the weight back on as it takes to take off as I inevitably revert to former diet choices...) and I never find the transition period difficult, but there's a consistent point where I hit "eh, still fat, but don't feel super fat anymore" and that's when the cravings or the pressures of eating non-keto with company have the highest chance of getting to me. There are also unforeseen stressors that can make things difficult (in my case a forced house move) but I'm ok with the state of flux. I don't want a six-pack physique enough, not really, and that's the last willpower component -- how long can you stick with it (and introduce more exercise), even with bumps and setbacks? My friend who introduced me to the diet lost 100 lbs by forcing himself to do keto for about 5 months, but he was fat enough at the start that he could stand to lose another 50 lbs but it's not as easy now. Still, he's much happier and healthier now than before. One's level of willpower is still involved even with how great keto is and is the difference between losing 50 lbs (not bad), 100 lbs (pretty awesome), and 150 lbs (your ideal).
