Complex carbs ("whole grain ___" should be first ingredient on label) instead of simple which are basically comprised of 1 or 2 sugars. Don't like wheat? Try oats, spelt, kamut, quinoa, etc. or legumes. Complex carbs are burned more slowly because they're long-chain molecules so you get a more steady source of fuel, plus the foods that contain them are usually good sources of soluble fibre which helps lower LDL cholesterol.
Exercise first thing in the morning. Jump-starts your metabolism for the day, plus getting the work out of the way early means you don't have to dread having to do it later in the day when you're mentally tired.
