The 80/20 Rule — Making the ASSFACE Diet a Lifestyle

Updated: May 20

Strict all the time? No thanks. Let’s keep it real.


If you’ve ever tried a diet that demanded perfection, you probably already know how that ends: burnout, cravings, guilt, and eventual quitting. That’s why the ASSFACE Diet was designed to be sustainable. And the secret to that sustainability? The 80/20 rule.


The 80/20 rule is a core component of the ASSFACE Diet

What is the 80/20 Rule?


It’s simple:


  • 80% of the time, you stick to your plan—no added sugar, focus on whole foods, plenty of fruits and veggies, and balanced meals.

  • 20% of the time, you leave room for life—dining out, social events, holiday treats, cheat days, or just giving yourself a little break.


Why It Works:


  • It’s realistic: Life happens. You’re not always going to be near a fridge of prepped meals.

  • It prevents all-or-nothing thinking: One “off” meal doesn’t mean you’ve failed.

  • It builds long-term success: You’re learning how to live in balance, not bounce between extremes.


What 80/20 Looks Like in Real Life:


  • Monday–Friday: You keep it clean. You follow the ASSFACE guidelines, choose no-sugar-added foods, and focus on your health.

  • Saturday night dinner out? Order a steak with veggies and a side of fries. Enjoy it. That’s part of the 20%.

  • Weekend birthday party? Have a slice of cake if you want it—but don’t let it snowball. Just get back to your usual eating at the next meal.


Pro Tips for Making it Work:

  • Keep your kitchen stocked with quick and compliant foods so the 80% feels easy.

  • Plan your 20% instead of letting it sneak up on you.

  • Don’t guilt yourself. Ever. Food isn’t moral—it’s fuel and sometimes, fun.

  • If you are new to health and fitness, start off following more strictly. It's easier to stick with 80/20 when you've mastered 100% for a few months.


Final Word:


The ASSFACE Diet is about better choices—not perfect ones. The 80/20 rule gives you the flexibility to live your life while still prioritizing your health. That’s not cheating the system—it is the system.
