Wellness and Self-Improvement

Key wellness strategies & self-care/productivity takeaways (weight loss focused)

Reframed “exercise-only” thinking

  • Learned that exercise increased his hunger, which led to eating more and stalling weight loss.
  • Conclusion: for him, weight change came primarily from diet, not training volume.

Tackled overeating with planned food structure

  • Started each meal with a large portion of vegetables (often about half the meal at first).
  • Used vegetables to:
    • Slow the onset of intense hunger
    • Crowd out space for richer/fattier foods

Removed processed carbs and “trigger foods”

  • Cut processed carbs completely, especially bread.
  • Eliminated: bread, cookies, cakes, soda, candy, and other processed foods.

Built meals around minimally processed, high-fiber carbs

  • Switched carbs to whole, recognizable legumes:
    • Chickpeas, lentils, beans
  • Emphasized whole foods and less calorically dense choices where possible.

Simplified, fast meal prep

  • Meals were typically under 5 minutes using canned/ready ingredients.
  • Point: healthy eating was not necessarily slower or more expensive for him.

Focused on “less appetizing” food to prevent overeating

  • Adopted an approach inspired by:

    “If it tastes good spit it out.”

  • Chose foods that are healthy but deliberately less craveable.

  • Rationale: in his case, highly enjoyable food was the main driver of stuffing himself.

Used behavioral awareness tools

  • Weighed himself every day to stay accountable.
  • Trained himself to stop before going past the point of “too much”:
    • Even during treats (e.g., pizza/pasta), he stopped earlier.
    • If the urge to keep eating persisted, he still stopped and noticed he’d feel full ~20 minutes later.

Eliminated alcohol and ultraprocessed foods

  • Avoided alcohol, candy/snacks, and ultraprocessed foods consistently.

Long-term health motivation

  • Refocused goals after realizing his “fat but fit” approach wasn’t sustainable.
  • Cited increased:
    • Slowness
    • Quicker sweating
    • Joint injuries
    • Concerns about long-term outcomes (including research about sumo wrestlers’ shorter life expectancy).
  • Motivation strengthened after becoming a parent (wanted to live longer).
