A single soft shell crab is also high in cholesterol at 79 mg per serving or around 26 percent of the daily recommended intake of cholesterol. According to the American Heart Association, dietary cholesterol intake should be limited to 300 mg per day for the average adult.
However, walking is an excellent long-term weight-loss exercise. You can easily walk thousands of miles over decades, because walking has a very low injury risk. How many calories you burn on a one-mile walk depends on your speed and weight.
The American Council on Exercise estimates that a 160-pound person will burn about 8.7 calories per minute walking and about 7.3 calories per minute biking at 10 mph. A person who weighs 180 pounds will burn about 9.7 calories per minute that they walk and 8.2 calories per minute biking at 10 mph. Therefore, walking typically burns more calories than biking at a similar pace -- and is thus more beneficial for losing fat.
