28-Day FAST Start

2 min read

  • Gin Stephens’ 28-Day FAST Start is designed to help your body adjust to the metabolic shift of intermittent fasting (IF) without the shock of a “crash diet.” It focuses on the transition from burning glucose to burning stored fat (metabolic flexibility).

    As you requested, here is the outline in Logseq-compatible Markdown:

  • The Three Entry Paths

    • Before starting, you choose a “speed” based on how quickly you want to shorten your eating window:
    • Easy Does It: Starts with a 12-hour window and gradually tightens. Best for those nervous about hunger.
    • Steady Build: Starts with a 16:8 approach (16 hours fasting, 8 hours eating). This is the most common middle ground.
    • Rip Off the Band-Aid: Jumps straight into a 18:6 or 20:4 window. Best for those who want to adapt quickly.

  • Phase 1: The Clean Fast (Days 1–7)

    • Primary Goal: Mastering the “Clean Fast.”
    • Rules: Only water (plain, unflavored), black coffee, and plain black or green tea.
    • Why: Anything flavored (even 0-calorie sweeteners) can trigger an insulin response, which halts fat burning and makes you hungrier.
    • Mindset: Focus on “Delay, Don’t Deny.” You aren’t telling yourself you can’t have a food, just that you are waiting for your window.

  • Phase 2: The Adjustment (Days 8–14)

    • Primary Goal: Managing “Appetite Correction.”
    • Physical Change: This is often the hardest week as your body seeks its “Appestat” (appetite thermostat).
    • Symptoms: You may experience “keto flu” or fatigue. Gin advises adding a pinch of sea salt to your water to help with electrolytes.
    • Action: Stick to your chosen window strictly to help your hormones (Ghrelin and Leptin) stabilize.

  • Phase 3: Settle In (Days 15–21)

    • Primary Goal: Finding your “Golden Window.”
    • Observation: Notice how different foods affect your next day’s fast. High-carb “feasts” may make the next day’s fast harder.
    • Focus: Transition from “eating until the clock stops” to “eating until you are satisfied.”

  • Phase 4: Tweak and Repeat (Days 22–28)

    • Primary Goal: Making it a lifestyle.
    • The Goal: By day 28, you should be comfortably reaching your fasting goal without intense hunger.
    • Non-Scale Victories (NSVs): Start tracking things like improved sleep, clearer skin, and steady energy rather than just the number on the scale.
    • Master the Delay: Move into a “Repeat” phase where you can occasionally flex your window for social events or family dinners without guilt.
