📋 The “Cleanse” Listicle: 5 Rules for Success

  1. The “Water Only” Rule: For these 10 days, your only drinks are water, black coffee, plain tea, or Spindrift. No soda, juice, or alcohol.

  2. The “Naked” Chicken Rule: Costco Rotisserie chicken is a lifesaver, but the skin contains most of the sodium and fats. Discard the skin immediately when carving to keep the meal “clean.”

  3. The “Half-Plate” Rule: Every lunch and dinner plate must be 50% greens or broccoli. This high fiber intake is what “cleanses” the holiday sludge from your system.

  4. No Added Sugar: If it comes in a package (like the salad kit dressings), check the label. If it has sugar or corn syrup, swap it for your Costco Extra Virgin Olive Oil and a squeeze of lemon.

  5. Salt Awareness: Use Better Than Bouillon sparingly and stick to avocado oil for cooking to avoid the inflammatory fats found in butter or margarine.
