Hm the only one I can find on the Costco site is 110 cals per serving + about 190 for the peanut butter, making for a pretty light breakfast. If the peanut butter is curbing appetite and this is the whole breakfast, it doesn’t necessarily need to be removed.
And yeah, definitely account for butter and oil. I was advised by a dietician to add tablespoons of oil into food (I use olive oil or avocado oil) for additional calories, which I do sometimes. It often makes the difference.
Are you losing any weight? I’m seeing a TDEE (calories per day to maintain) of 3300~3700 depending on much you work out on the five days a week I think I saw earlier. The formulas aren’t always accurate but they’re rarely that far off, and I think it’s somewhat unlikely that your count is off by 1500+ calories a day. It definitely is possible, I’ve read weight management stories like that, but if you start weighing your food and adding calories from oil + butter and see no weight loss I’d consider asking a doctor.
Feel free to ask if you have any questions, I’ve been counting calories and measuring my weight every day for a very long time now. I have my weight management down, and while my experiences may not be applicable for you, I’m happy to elaborate on anything. Weight management is difficult and sometimes a truly long term commitment.
