I missed that, "a tub". Do you mean the entire cotto container? I dont recommend that, however, But, with that said, if your STILL in deficit, its all good, with the exception of a variety set. Yes, I forgot about the differing measuring systems, so you could be right.
For example this is what I eat before bed sometimes (with a NEW 24 hour cycle starting at 12A, that is): 1 serving (measured) PB with ONE slice of pita bread, 1 can of tuna, a small salad (with veggies), and a small grapefruit. A nice variety. I dont worry about the fruit before bed, its doesnt effect my body that much, and blood sugar rise, is minimal.
