I am a big fan of 40/30/30. There is way too much focus on 'low fat' without the consideration of what else you are eating. Most people's carb intake is so high that lowering your fat intake effectively increases your carb %. Look at a carton of milk: Read the carb amount on whole vs. lowfat/ nonfat. Watch the carb calories go up as you take out more fat. IMHO: DUMB!

Personal choice: Mountain High Original Style, Plain yogurt. Low carb, no crap

Drop your carbs to 40%, raise your protein to 30%, pay less attention to your fat intake. As a vegetarian it's hard to get too much fat unless you eat a TON of nuts. Please eat some however; many, many nutrients to balance out your intake. Good luck!
