Yes, being healthy is enjoyable. Sometimes protecting ones health means not doing those things that provide superficial, temporary feelings of joy (junk food, artificial sweeteners that could lead to cancer and other health issues, smoking, etc.) that are in fact bad for our health and likely to reduce long term joy.

You can do just about anything in moderation and it won't be bad for you, short or long term. For example, having a cigarette or two a week over a few beers with some friends. Completely abstaining from superficial, temporary feelings of joy can be detrimental to some people when they finally do give into temptation.

  Life is meant to be lived.

A tautology at best, but more likely empty rhetoric.

  Make healthier choices, but still enjoy.

This assumes healthy choices cannot produce enjoyment.

  Otherwise, what's the point?

In our modern times, it seems to me, the point of life is whatever you make of it. I'm getting the impression that the point of your life is to experience as much pleasure as possible, i.e.: hedonism. This is a perfectly valid approach to one's life, but I wouldn't assume that others are getting less enjoyment out of their existence simply because they choose to impose constraints on the pleasures they pursue.
