Google wants to count calories in your food photos someday, but until that happens, it can at least help you speed-search popular fast food meals. Say, you want to know what exactly you're consuming when you eat a Big Mac -- just type "calories in a Big Mac" or say it out loud after "OK, Google" using voice search on your mobile app. A box containing the food's complete nutritional information (calories, carbs, fats, etc.), similar to what you see on calorie-counting apps like MyFitnessPal, will then show up on the results page. You can also search for a fast food chain's full menu and click on each item to show its nutritional values. For instance, you can type in "Burger King calories" for a quick check before you order. That way, you won't end up buying a Triple Whopper if you're not ready to consume a whopping 1,160 calories in one sitting.
