Frozen yogurt is a multi-million dollar business dishing up many unnatural ingredients with loads of sugar, and some active cultures for good measure. Don't be fooled, comparatively it's much closer to ice cream than yogurt.

What's wrong with frozen yogurt?

Frozen yogurt can be a carbohydrate bonanza. Think salad bars: the ingredients may seem healthy but it's easy to exceed 1,000 calories.
"Sugar can be represented by a whole host of sneaky aliases on an ingredient list: fructose, dextrose, corn syrup, juice concentrates, polydextrose and pure cane sugar," writes the Huff Post, adding that one product might list sugar by several of these names to keep it from topping the ingredient list.
Nutritional information at most fro-yo shops isn't usually front and center either; if you want the information you have to ask for it.

How do I keep it healthier?

Reverse the cup - Put the toppings in your cup first and the frozen yogurt on top to moderate carbohydrates and calories.
Portion control - Fill your cup halfway or ask for a smaller one. One size (giant) cups at self-serve spots tempt customers to fill it up.
Weigh before adding toppings - Four to five ounces is a good serving, think about the size of a tennis ball.
Pick a low-sugar option - Some frozen yogurts are made with splenda for instance.
Go for healthy toppings - Fresh berries or nuts are great; fresh fruit gives the appearance of a full cup satisfying a hungry eye.
Eat frozen yogurt as an occasional treat.
