If Im eating Fage 0% greek yogurt, 1 cup is 130 cal 9g carb and 23g protein. should I add another carb?
also if im 140 5'4 i should be eating 20/20 protein/carb each meal correct?
Yes to the carb.
140lbs divided by 6 meals = 23
If you wish to drop your scale weight, you can try 20-23g for a few of your meals gradually to see how you feel in relation to energy and recovery. I wouldnt drop the grams in all the six meals though IMHO.
I hope that helps.
