The toothless FDA allows for a 20% margin of error on nutrition facts labeling, so it could possibly be one or the other or both.

Some products may just have variation. Some foods will be maliciously mislabeled with 19% less calories/sugar/fat but may have little to no variation within the same product.



I am beginning to believe those who count calories and lose less weight than they anticipate.


Yeah 20% is massive if most of your calories come from carbs.

Sensible dieting talks about 10% reductions in intake along with light exercise.

Trying to manage that by those labels would be impossible.

However eating packaged processed foods isn’t a very good way to lose weight anyway.

I lost 180lbs a few years ago by cutting processed food, soda and alcohol out of my diet. Didn’t change anything else.

I presume the carbs in veggies are pretty much accurate by weight a carrot is a carrot (except for water content).
