But, almond butter is also high in calories, so if you're watching your weight, you'll need to take serving size into account. In fact, almond butter is very 'calorie-dense' because it has 98 calories per tablespoon, mostly due to the 9 grams of fat in that one tablespoon serving. That can be bad for a weight loss diet if you eat more than a serving and don't account for all the extra calories.
