@thefitnesschef_ on Instagram has an infographic showing some Starbucks drinks and the calories they contain. The drinks listed are based on the size called Grande with 2% milk and whipped cream for the frappuccinos. Your best bet is the plain Caffe Americano showing 0 calories (of course before anything is added.) The next lowest calorie count listed on the infographic isn’t even coffee…it’s Teavana® Shaken Iced Passion Tango™ Tea.
You don’t have to rely on just this infographic. If you need more information, you can go right to the Starbucks website and look at the nutrition listed for all their drinks. They have a separate nutrition listing for their food as well. When I look at some of the calorie counts for a single cookie – that’s more than some people have for whole meal.
It’s not a pleasant subject but you should be aware of the calories you are consuming.
