McDonald’s Shamrock Shake is one of those limited time items that rotate on and off the menu seasonally like the McRib. The shake has become extremely popular among McDonald’s fans for its delicious minty flavor, but even more so, for its highly complex texture, which feels almost like a mousse. Some people hate it though.

The Shamrock Shake is a carb bomb. Even in its smallest version, you’ll be looking at a minimum of 74 grams of carbs per serving. And if you decide to order the Large Shamrock Shake, then that’s 131 grams of carbs right there.

The calorie content varies. McDonald’s Shamrock Milkshake contains between 460 and 800 calories, depending on serving size. For comparison, a 100-minute brisk walk will burn between 480 and 600 calories, depending on sex and age.

So I guess the old adage is true:

Life is a tragedy of nutrition.
