I agree it's our interpretation, but I think it's a reasonable one. The Daily Dish (and a lot of what the SBD folks write) is sometimes unclear. Here's a link to the Daily Dish that mentions the limit:
viewtopic.php?f=2&t=98372It says the limit is two 1-ounce servings of cheese per day. This could mean:
* Don't eat more than 2 ounces of any kind of cheese (cottage cheese or any other kind) per day, or
* Don't eat more than two servings (regardless of the serving size) of any kind of cheese, or
* Don't eat more than two servings of any kind of cheese that's measured by the ounce (referring to the limit on fat of 6g per 1 ounce of cheese)
The first one makes no sense. One ounce of cottage cheese is less than 1/8 of a cup, which is barely anything. I think the second one must be wrong too, because the Daily Dish specifically mentions the 1-ounce serving size as part of the limit. So I think they must have meant #3.
The "cheese limit" is also part of a sentence about the importance of limiting saturated fat, and even 2% cottage cheese, the fattiest kind allowed on SBD, is still very low in fat (about 2g to 2.5g per half-cup serving).
Of course, it's probably possible to overdo even nonfat cottage cheese and someone might have trouble losing weight if they eat too much of it.
