Exactly how many steps it would take to burn off your St Paddy's Day favorites  trends now

St Patrick's Day is just around the corner — a day when Americans don green and kick back a few pints at a local bar.

Many major American food chains also cash in on the holiday, offering limited green and leprechaun-themed treats. What might go unnoticed during festivities is how unhealthy many of these treats are and how far you would need to 'walk it off' later.

Dairy Queen's Mint Brownie Blizzard and Jack in the Box's Mint Mobile Shake, for example, both have over 1,000 calories each.

For the average 5'9 male person to walk one of those off it would require a 14 mile stroll — or nearly 30,000 steps - which would take you nearly five hours.

Even a pint of the iconic Guinness Draught — a staple on St Paddy's Day —  carries a large sum of calories, with more than 200 per pint. Drink four of those, which is not too far-fetched, and you'd need to walk nearly 10 miles.

Unfortunately, many Americans hoping a brisk walk in the park is enough to offset a day of treats and drinks may be in for a big surprise:

McDonald's Shamrock Shake 20,000 STEPS 

The popular drink from the Golden Arches is a staple St Patrick's Day-themed drink.

The iconic green drink has made an appearance on McDonald's menus each March for more than 50 years.

What's hiding in the pale green milkshake with whipped cream on top is enough calories to undo a whole day's workout.

A large Shamrock Shake has 800 calories. Experts suggest a person that weighs 150 pounds burns off 40 calories with every 1,000 steps taken.

This means an average person will have to walk 20,000 steps — enough to travel ten miles — to undo the caloric impact of the drink.

Calories are not the only worry. 

The 84 grams of added sugar in a large shake is also well over the 50g daily maximum recommended by the Food and Drug Administration (FDA).

There is also 13g of saturated fat, 64 percent of the maximum, and 260mg of sodium — 11 percent of the max allowance.

Krispy Kreme's Golden Cookies & Kreme Doughnut 10,250 STEPS 

Stopping at Krispy Kreme to grab a few doughnuts is a part of the morning routine for thousands of Americans, and the chain has a few St Patrick's day themed treats available this month.

Krispy Kreme has seven holiday-themed doughnuts this month, each based on the holiday.

These include the Golden Cookies & Kreme Doughnut, a cream-filled doughnut topped with white icing, golden cookie crumbles and sprinkles.

The treat is based on the famous unfound pot of gold believed to be hiding at the end of rainbows across the world.

While there are some disputes over how likely you are to find riches at the end of a colorful crescent — the amount of sugar and calories in Krispy Kreme's doughnut is known.

The doughnut has 410 calories. Just one would take 10,250 steps, or walking 5.13 miles to burn off. 

Limiting yourself to just one can be a challenge, though, with many eating a few treats at a time. This
