I just recently got a food scale and I tried to weigh a Hamburger Helper dish.It said my total weigh minus the plate was 210g.On the box it says that 35grams are 9% carbs.Do I divide the 9 by 210? I tried it on the calculator and it said more carbs than the box.
you go by the box, as it is by volume, not by weight.
I agree with landileigh. I would go by the book. Food scales are great for weighing home cooked meals.
i go by the serving on my meals not the hole box by the amount per serving it seems to work for me.
What you need to look at is the number of grams of carbs, not the percentage. The percentage is based on if you eat the average recommended amount of food for the average person - very few people are “average”, and most diabetics have different nutrition guidelines.
I found a sample nutrition panel for Hamburger Helper (cheeseburger macaroni, my fav!) here.
Looking at that, it tells me that 1 cup prepared (which is important - some boxes have only the nutrition facts for unprepared, which is VERY different) is 27 grams of carbs with 1 gram of fiber. Fiber isn’t digestible, so you can ignore that 1 gram, giving us a net carb number of 26 grams of carbs for 1 cup prepared.
The web site I linked doesn’t have a weight for 1 cup of prepared hamburger helper, but the real box will. Let’s assume it’s 35 grams (which doesn’t seem quite right - I think 1 cup would weigh more than that, but we’ll use it as an example). So for every 35 grams you eat of it, you’ll be eating 26 grams of carbs.
210 divided by 35 = 6. 6 times 26 (the net carbs per serving) = 156. So the entire box has 156 carbs.
Does that make sense?
