I Tried The World’s Simpliest Diet for 30 Days (INSANE RESULTS)

Overview of the “World’s Simplest Diet” 30-day experiment

The video creator tried Jeremy Ether’s “30 Days on the World’s Simplest Diet” with the goal of losing fat and building/maintaining muscle without calorie counting or feeling restricted. The approach uses a repetitive, simple, plant-based template centered on:

• Potatoes
• Tofu
• Lots of vegetables

---

Key wellness + self-care / productivity lessons (what they focused on)

• Replace decision fatigue with simplicity

  • Eating the same “component bowl” structure reduces constant food planning.
  • They emphasize habits on autopilot as a major reason consistency was easier.

• Manage digestion by adjusting vegetables

  • They initially felt bloated/gassy, especially from broccoli and lots of raw fiber.
  • They improved comfort by:
    • Cutting broccoli
    • Cooking carrots
    • Reducing protein powder used late at night

• Support training/body goals while staying flexible

  • Targets included:
    • Strength training ~3x/week
    • Walking ~10,000 steps/day
  • They stress that even when workouts/steps were missed, progress still happened, so perfection isn’t required for fat loss.

• Timing changes to reduce late-night eating

  • After week 3, they tightened the routine by:
    • Stopping eating late at night
    • Using low-calorie, filling swaps at night (e.g., kabochа squash)

The diet structure (main methodology)

They describe a repeatable meal template designed around calorie density and protein adequacy.

Vegetables at every meal

• Target: ~half a pound of vegetables per meal
• Initially: mostly broccoli + carrots
• Later: expanded to more non-starchy vegetables (e.g., tomatoes, celery, eggplant, mushrooms)

Potatoes as the main calorie source

• Primary carbs: potatoes / sweet potatoes (including Japanese sweet potato)
• Strategy: use potatoes for both:
  • Calorie control (lower calorie density)
  • Satiety
• Other carbs (rice/pasta/beans) were only occasional (e.g., Friday night / once a week)

High-protein base (plant-based)

• Protein source: tofu
• Aim: about 150g tofu/day (described as “one packet”)
• They mention swapping in other oil-free protein options when appropriate (e.g., oil-free versions of soy-based products)

Low-calorie fruit for volume and enjoyment

• Fruits used included:
  • berries, melon, apples, pears
• Fruit also helped reduce feelings of restriction.

No/low oil + minimal processed add-ons

• They recommend eliminating oil due to its high calorie density.
• Flavor is supported using condiments such as:
  • mustard, hot sauce, salt/pepper
  • kimchi, banana peppers, pickles

“Component bowls” (repeatable meal formula)

Each meal is built like this:

• Protein “sauce”: tofu (oil-free)
• Huge portion of vegetables: ~half a pound
• Potatoes/sweet potatoes: main calorie source
• Low-calorie fruit: variety for adherence
• Optional: low-calorie condiments for satisfaction

---

Training/productivity emphasis (practical adherence tips)

• Walking + strength training were goals, but adherence wasn’t perfect.
• Results improved when they tightened the basics:
  • More consistent steps (10k more reliably)
  • Less late-night eating
  • Better digestion management (e.g., removing broccoli triggers)
  • Daily abdominal circuit during the challenge

---

Results mentioned (high-level)

• Personal scale weight: about -2.3 lb over 4 weeks, with better body composition than scale weight alone suggested.
• Later InBody (around ~6 weeks):
  • Body fat % dropped significantly
  • Skeletal muscle mass increased
• Client Dana:
  • -5.3 lb total in ~26 days
  • ~4 lb from body fat
  • Body fat %: 24% → 22.6%

---

Main takeaways (explicitly listed)

• Vegetables at every single meal (upgrade from “two meals” to all meals).
• Make potatoes (or sweet potatoes) your main calorie source for fat loss + enjoyment.
• Use component bowls to make meal planning effortless:
  • protein base (tofu/oil-free option)
  • lots of vegetables
  • potatoes/sweet potatoes
  • low-calorie fruit
  • flavorful low-calorie condiments
• Remove oil to make portions easier and the diet more effective.
