In fact, very few foods have such potential to be a dietary frenemy. Sugar levels in fruit and juice can boost calorie counts well above a large shake from McDonald's! Be alert to exactly what your shake barista (shakeista?) is putting in your drink, because he could be whipping up a wider waistline for you. Here's an example of what can go awry at Smoothie King, a popular and growing chain that offers dozens of the blender bevvies.

See what we mean about frenemies? Well, the Hulk is a downright menace to your diet. The promise of strawberries' fat-burning power might draw you to this drink, but steer clear: It's actually what Smoothie King calls a "weight gain" drink, with butter pecan ice cream, bananas and something labeled a "weight gain blend."
With nearly 1,000 calories, it's the equivalent of Burger King's Double Whopper With Cheese! The simple, high-protein Gladiator has two kinds of protein powder, which will help you build lean muscle and keep you sated.
You have the option of adding two fruits to that protein base; if you'd like, opt only for fresh strawberries, which pushes the calories to a reasonable 320. Steer clear of the juice blends (varieties include blueberry and passionfruit), unless you want to go on a Hulk-like sugar rampage.
