Like high-speed monorails, digestive systems work best when they're kept clean, devoted to a regular schedule, and free from dangerous obstructions on their pathway. Keep bodies bustling like clockwork with today's Groupon: for $50, you get a colon hydrotherapy session plus detox or weight loss diet at Healing Waters Colon Care in Huntington Beach.

Desiree Wilson, certified colon hydrotherapist, nutritionist, and owner of Healing Waters Colon Care, helps patients detoxify from the inside out with colonic treatments and expert diet guidance. Relaxing upon the Hydro-San closed system table, patients lie back and allow warm, filtered water to flow like a gently babbling brook, cleansing interior plumbing fixtures during this 45- to 50-minute treatment. The water softens and flushes away impacted waste matter found loitering in the bowels, in turn improving the gut's ability to absorb minerals and boosting overall energy levels. In addition to doling out detox or slimming diet advice, Desiree recommends drinking a tumbler of raw carrot or celery juice the night before a colonic appointment to ready the digestive tract and regulate traffic patterns on the digestive highway.
