I was going say what Monsta asked. I'm only 225+- and taking in 2500-2800cals depending on the day and slowly losing weight.
Your basically protein and veg?maybe you should increase your fat intake . if your not taking carbs (and I don't count veg, but they are very good to have) , than you should keep your fat higher(40% or so) or I think you will turn the protein in to carbs to use that as energy.Fat/protein is a very good diet to help you lose weight and maintain size/strength.
Do you have a carb up day every 7th day or so ? Sometimes that shock is enough to help lose a few more lbs once you start to drop out the carbs again. Some people can go 48hrs with carbs , some can only do 12-24 it all depends.
Ever think about
www.redpointfitness.com ? It is a vey good site , with some very knowledgable people on their. It does cost , but not much at all.
