Is this true in practice, for most practitioners? It's sometimes hard to tell how ideals match up to reality when it comes to this stuff, for those without first-hand experience. For my part I've read a fair amount about Buddhism but the real-life experience of a lay practitioner or monk remains obscure to me.

In reading about Christian monastics I've found that their fasting practices are, and were even in the middle ages, much less dramatic than they seem at first glance, except in relatively rare cases. For one thing, many fasts aren't so much "don't eat" but "eat somewhat less, but still quite a bit", and there are tons of feast days to counter-balance that. And even those rules are thrown out for older monks and any who are ill, of course. You look at their calendar and think "damn, that's a lot of fasting!" but then you read accounts by actual monks and more detailed sets of rules and find they did very little actual no-eating fasting, in the typical case, and many "fast days" still involve a lot of eating.
