Cross-Country Skiing Burns More. Burning about 381 calories in 60 minutes of snowboarding provides a slower caloric burn than some other forms of winter exercise. A 160-pound person burns about 533 calories in an hour of slow-paced cross-country skiing and about 419 calories in 60 minutes of light ice skating. The caloric burn from light snowboarding is equivalent to that of light downhill skiing. Related Reading: How to Estimate the Total Calories You Burned While Running.
A daily calorie deficit of 675 calories would lead to a deficit of 246,375 calories over the course of a year (675 calorie deficit x 365 days = 246,375 calories). This would, theoretically, lead to a 70-pound weight loss for Vanessa (246,375 calorie deficit / 3,500 calories in 1 pound of weight = 70 pounds lost). But the body doesnât work that way. Instead, Vanessa would lose about 40 pounds.
