The 'tummy bloating' is what scream 'intollerance' to me. I would suggest eliminating one thing for a week or two and guaging your reactions. Start with the soy milk (soy is a common allergen). And tracking exact numbers for a few weeks would also be a good idea - you may be getting more than 60g of carbs a day (although it doesnt look like much more).

Are you losing inches? lbs?
