    And, this will all be available on your smartphone or other mobile device!

    What Do You Need to Do?

    The message board you're used to will be closing in the coming weeks. While many of your boards will be making the move to our new home, your posts will not. Want to keep a discussion going? Save posts you want to continue (this includes your member profile story), so that you can re-post them in the new message boards.

    Hi hethro,
    You're smelling acetone on your breath. Acetone is one of three ketone bodies; ketones are compounds that are the byproduct of fat metabolism. They have a metallic quality and can smell like ammonia on the breath. They can occur for a number of reasons including when people go on low carbohydrate diets, when people lose weight and burn lots of fat, and when people do lots of aerobic exercise. They generally do not rise to dangerous levels before the body metabolizes them, and they are typically not dangerous unless you have type 1 diabetes. They are a source of fuel for skeletal muscle as well as the brain and should not interfere with performance. Staying well hydrated will help flush them out. Hope that helps.

    Take care,
    Rich
