Last week, I told you five food tweaks that can make your Buddha belly less ... um .... Buddha-ish. But if changing what you eat isn't your thing, Prevention Magazine recently revealed another five tips -- no diet changes necessary. Here they are:

• Stand -- and sit -- up straight. Good posture instantly slims your whole body, but especially your ab area.
  
• Imagine there's a magnet behind your belly button drawing it to your spine. It's an old Pilates trick that works wonders. Do this often.
  
• Sit like royalty. Allow your spine to curve naturally and hold your shoulders back.
  
• Become a cardio queen ... or king. It's effective in burning stubborn fat.
  
• Clean your house. Seriously. Vacuuming, sweeping and scrubbing uses your core muscles.
