Agave nectar, also called agave syrup, is comprised primarily of fructose and is about one-and-a-half times sweeter than table sugar. Because you need less agave nectar to obtain the same level of sweetness, it is a good way to cut down on sugar and save calories, which is especially helpful for diabetics.
Agave nectar has 60 calories per tbsp. or 960 calories per cup. All the calories in agave nectar are from carbohydrates. No fat or protein is in agave nectar. Of the 256 g of carbohydrates in 1 cup of agave nectar, which supplies 5 percent of the daily value, fiber content is 16 g and sugar content is 240 g, according to FatSecret.
Unlike sugar, agave nectar is low on the glycemic index, or GI, rating. This means it won't cause a sudden increase in your blood sugar levels. High GI foods such as white sugar are digested quickly, and you may feel hungry sooner, according to FitSugar. Foods made with agave nectar may keep you feeling fuller longer, which results in consuming fewer calories.
Although 1 cup of agave nectar is a lot to ingest, to burn those calories you would need to snowshoe for 106 minutes, jog for 2 hours or jump rope for 86 minutes, according to Calorie Gallery calculations.
