Instead of cutting all pastas, why not switch to whole grain versions, which are much healthier, and limit portions? You should also switch to whole grain breads.
Don't cut out meats; they're a major source of iron and vitamin B12, both of which are essential for providing energy. Make sure you opt for leaner (low fat) cuts and stick to smaller portions. Opt for chicken or fish, as much as you like; just make sure it's grilled, broiled, or baked vs fried.
