As the weather gets warmer, it's tempting to cool down with some creamy, dreamy ice cream, but if you're priming your body for bikini season, those confections can cause a major setback. The most decadent flavors can set you back more than 300 calories and 20 grams of fat - and that's just for a half-cup serving size! Even so-called "light" selections can pack in more than 20 grams of sugar, not to mention cholesterol. So what's an ice cream lover to do? Try some sensible substitutions, like sugar-free popsicles. If you've got a chocolate craving, then a fudgsicle will do the job nicely. Or try melting semisweet chocolate morsels and dipping peeled bananas in them. Add a stick and freeze for a sweet, delicious treat with a fraction of the calories and fat of ice cream. Smoothies made with bananas, peanut butter and protein powder do the trick when you're craving an energy booster.
