If you're a full grown adult male, circumcision is hard. Adventists don't keep the Sabbath, they just think they do, they travel on church days and use electricity. Try keeping it the way the orthodox Jews do, not allowed to light a spark. Hardcore - now THAT's keeping the Sabbath. Food laws - yeah it's pretty hard to avoid anything in our society that has a bit of pork or ham in it, or find kosher foods conveniently.
Eating kosher is easy. Going out to restaurants and trying to eat kosher isn't so easy.
