There are few things more enjoyable than spending a warm summer evening outside with a double scoop of ice cream. But if you're dieting this summer -- or even just trying to break even by not gaining extra pounds -- ice cream on a regular basis is a definite no-no. And Gelato, its lower-fat alternative, isn't much better either, as we told you a few weeks ago. So what's a cold treat lover to do?

Frozen yogurt seems like a good alternative. After all, yogurt's a health food right? What do you think?

The answer is 460 calories in a large cup of frozen yogurt (that's the 96 percent fat-free variety) from TCBY, according to the 2009 Calorie King Calorie, Fat and Carbohydrate Counter. The good news, of course, is that it's fat-free (well, except for that 4 percent), but when you consider that a serving of Cherry Garcia is only 220 calories, it seems you'd be better off just sticking to ice cream!

Of course, you have options. Opt for a small cup of fro-yo and you're looking at 280 calories, which isn't great but cuts your calorie intake by a whopping 200 calories. Other sweet treats to wet your whistle: A popsicle has between 40 and 60 calories, and a fudgsicle has around 100 calorie.
