We all need a little food reset from time to time. If you’re looking for a plan that will get your rear in gear , we feel you. Here’s one way to do it: the Whole30 program.

Whole30 is a 30-day (duh) clean-eating plan designed to revamp your eating habits by cutting out certain foods. And yes, we’re talking about some foods that are super hard to give up: dairy, sugar, grains, legumes, and alcohol.

Committing to the Whole30 is breaking up with the booze-filled, dessert-every-night, carb-fueled diet we’ve come to know and love (French fries are vegetables, right?). Instead, you’ll be swiping right for clean proteins and veggies. Let’s break that down.

All hail the “yes” list.

  • Meat. Yes to a burger, no to a bun.
  • Poultry. So. Much. Chicken. Sausage.
  • Fish. You can even eat the canned stuff.
  • Veggies. Your options are limitless.
  • Fruits. An apple a day keeps your sweet tooth at bay.
  • Fats. Avocados every single day.

Oh, and coffee! There are also a few ridiculously good store-bought foods that are Whole30-approved. They’ll make this plan a wee bit easier. Hello, clarified butter and coconut aminos.

Brace yourselves.

  • No sugar or natural or artificial sweeteners. Nope, not even maple syrup.
  • No booze. Unless you’re talking about the trace amount of alcohol in kombucha.
  • No smoking. We mean weed, too.
  • No grains. Time to empty your jar of quinoa.
  • No beans or legumes. No chickpeas, no peanut butter.
  • No soy. Tofu is a goner.
  • No dairy. Cheese is dairy, guys.
  • No processed additives. Carrageenan, sulfites, MSG.
  • No fake treats, even with Whole30-approved ingredients. Sorry, cauliflower crust pizza and Paleo pancakes, you’re off-limits. This rule is all about building a healthier relationship with your food, and we think it actually works.

You got this. It’s just 30 days. *Insert sweating emoji*

Before you run away, there’s good reason those foods are off-limits. We can’t guarantee everything on this list is going to happen to you, but these are the most common benefits some people have experienced while on (and after) the Whole30.

  • Weight loss. We can’t complain.
  • Health conditions may improve. Headaches now only happen when we’re hungover.
  • Digestive problems resolved. We can finally poop twice a day!
  • Skin is clearer. No more teen acne in our 30s.
  • Energy levels are through the roof (a.k.a. Tiger Blood). What third cup of coffee?
  • An entirely new list of tasty recipes. Seriously, it’s good food.
  • Transformed taste buds. Cravings for pizza subside faster these days.
  • More effective workouts. We didn’t stop to walk at mile 2 during a 4-mile run.
  • Improved sleep. We had the energy to wake up for said run.
  • Discovered what foods make us feel like crap. This is different for everyone and something some noticed once processed foods were added back into the diet on day 31. For some, it’s cheese. For others, it’s bread.

You’re going to miss your morning doughnuts for sure, but this isn’t like any diet you might be used to. Here’s why:

  • You’re not tracking calories.
  • You shouldn’t feel hungry.
  • You won’t be eating based on a points system.

Whole30 co-founder Melissa Hartwig actually doesn’t like calling the Whole30 a “diet” at all. “Most diets are spent white-knuckling your way through deprivation, restriction, hunger, tuning out your body’s signals, and obsessing over tracking and weighing your food,” Hartwig says.

She doesn’t think that type of behavior is sustainable, and if you’ve ever tried dieting, you probably agree. Also, weight loss isn’t the sole focus. You’re not even supposed to weigh yourself, except for on days 1 and 30.

Of course, sliding into your usually-too-tight jeans on week three feels pretty damn good, but Hartwig wants the focus to be on feeling better overall. Weight loss is the cherry on top.

Why 30 Days?

Why not 27 or 43? “Thirty days is a good compromise. It takes 66 days for a habit to stick, but if we told someone to do this plan for that long, it’d be pretty intimidating,” Hartwig says. This amount of time is long enough for you to see results but not so long that you’ll be afraid to start [Lally P, et al. (2009). How are habits formed: Modelling habit formation in the real world].

No cheating, kids. Hartwig emphasizes the importance of sticking to this plan with zero slip ups, so you give your body the complete break from not-so-healthy food that it deserves.

If life happens and a glass of wine or a piece of bread gets in the way, Hartwig recommends starting over. She wants you to feel the full benefits of the entire 30 days.

We’re not gonna lie: Some of us have let a glass of wine slip before. We didn’t start over and still felt on top of the world at the end. We aren’t suggesting you do the same, but we’re just being real.

Here are some official and unofficial rules we follow to get us through the program.

Do it with a friend

Surround yourself with support. “Touch base with [other Whole30ers] every single day. Ask for help when you need it. Be authentic with your successes and your struggles. Share resources and take the time to offer advice to others where you can,” Hartwig says.

You can also follow Whole30 on Instagram to connect with like-minded people.

No fake treats

This one was hard for us to grasp, so it deserves some explanation. If a Paleo pancake calls for nothing but Whole30-approved ingredients, such as eggs and bananas, the flapjack is still off-limits. The Whole30 wants you to change your habits and your emotional relationship with food.

“Your brain doesn’t know the difference between an almond flour brownie and your mom’s recipe, it just knows you crave sugar. So, if you keep eating those sweets during the 30 days, your habits aren’t changing,” Hartwig says.

Don’t shoot the messenger!

Read the Whole30 book

The Whole30 book is helpful, clear, and will get you motivated. Want even more Whole30 ideas? Hartwig’s cookbooks may not have the nitty-gritty plan details, but the recipes are solid.

Clear your house of temptations

Hartwig calls these “foods without brakes.” The ones that give “once you pop, you can’t stop” true meaning. Say goodbye to everything on the “no” list. Toss it, pack it, send it to your grandmother. Just get it out.

Celebrate with coffee

You can’t drink alcohol, but you can turn your after-work happy hour into a midday coffee date. You can drink black coffee with a splash of unsweetened non-dairy creamer.

Plan and prepare

This is Hartwig’s No. 1 tip when it comes to success on the Whole30. No more grabbing a slice of pizza on the way home from work.

“Before day one, you should have your first week of meals planned, grocery shopping done, pantry stocked, and you should have some Whole30-compliant emergency food stashed away,” Hartwig says. Here’s a Whole30-approved shopping list to get you started.

Don’t make it complicated

You’ll be exposed to a ton of new, delicious recipes. If you know you’re not the cooking type, start simple.

Instead of making the fancy egg-bake in a cast-iron pan, grab some eggs, veggies, sausage, and avocado then scramble your breakfast. Top it with sugar-free hot sauce, and you’ll have yourself a solid meal in seven minutes.

Don’t be afraid to make that for breakfast five times a week — making similar meals over and over again is easier than trying to whip up new complicated ones.

Always make leftovers

For lunch and dinner, make extra so you have leftovers. There’s nothing more rewarding than knowing your meals are already cooked and ready to go for the day. Pat yourself on the back and have a party.

The Whole30 is too legit to quit, so we asked Hartwig to give us advice to help us get through it. We’ll leave you with this:

“The struggle is a normal, necessary part of the process. Changing your food is hard. Changing your habits is even harder. Changing your relationship with food is the hardest part of all.

The process requires struggle — it’s how you know you’re growing — but don’t make it harder than it has to be! There is no such thing as the “perfect” Whole30, so if your beef isn’t grass-fed or your travel meal doesn’t look exactly like our meal template, don’t sweat it.”

Your only job is to stick to the Whole30 rules for 30 days, and some days, you’ll have to let good enough be good enough. And high five yourself for the victories you’re achieving every day, no matter how small.
