Calories and carbs

Until recently most of my focus on the Nutrition Facts label during my food shopping had been on the carbs. But I've been looking at calories more closely.

Yesterday I looked at a tub of sour cream at the grocery store. A 2 tablespoon serving had 2 grams of carbs. It was the same for regular sour cream and low-fat sour cream. No difference in carb count. But the regular sour cream was 60 calories per serving, the low-fat 15 calories.

No wonder I was having weight problems. That paying attention stuff really is important.
