I have more muscle than fat, I want to slim down but how?
Non expert advice here but here's my thought:
Focus on breakfast and lunch and cut dinner down to a minimum. Consider a lower carb diet. Basic cardio is your work out of choice.
You know, one more thing I might add, I'm from California myself, but I've been living in Vietnam for a couple of years. I notice that when I'm over here I tend to loose weight quite a bit. I do a lot less exercise here than in California, so I think it's the eating style.
Over here I tend to eat with everyone in a family style meal (typical of this part of the world). Everyone gets a very small bowl with rice, and the rest of the food is in the table center for everyone. This makes it really easy to only take what you feel like.
I'm assuming from your name that you might be American, so I might also offer the suggestion, if it fits your lifestyle, of doing more family style meals where everything comes in small portions. Reduce the size of plates, force more trips to get 2nds, 3rds, etc. It seems to make it easier to slow down and eat less naturally.
I've never quite replicated this myself back in the US, but I definitely notice the difference when I'm over in Asia. I think it's a difference in average portion sizes.
It just popped into my head so I thought I'd share it.
