It鈥檚 hard keeping up with the Kardashians/Jenners 鈥 between sisters Kourtney, Kim, Khlo茅, Kendall, and Kylie, there are endless endorsements, clothing brands, beauty lines, retail stores, emoji, websites, apps, mobile games, books, and about a million shows and spin-off shows. It really is a full-time job just to track who is doing what and when, and we haven鈥檛 even gotten started with North West and her fashion trendsetting ways. One thing that seems fairly constant, however, is their dedication to fitness and healthy diets. So in the name of research, we pored through all their websites, apps, social media, and more to find out what exactly each sister is and isn鈥檛 eating. You鈥檙e welcome.

KOURTNEY: GLUTEN AND DAIRY-FREE

A post shared by Kourtney Kardashian (@kourtneykardash) on

The eldest Kardashian is probably the most health-conscious of the clan; she and her kids eat an organic, dairy-free, and gluten-free diet. And clearly, it鈥檚 working for her: After three kids, she鈥檚 still rocking a bikini-ready body (of course, her frequent workouts with Khlo茅 also have something to do with it).

On her website, Kourtney gave readers a peek into her non-dairy refrigerator (staples include coconut milk, almond milk cheese, and coconut milk frozen desserts) and her pantry, which is so meticulously organized that it鈥檚 practically art (it also holds so, so, much water).

Meals: For breakfast, Kourtney has her three-ingredient avocado pudding (one whole avocado, a cup of coconut milk, and Manuka honey) or a banana spinach shake (avocado, banana, spinach, and almond milk). Lunch could be veggies with hummus and turkey with gluten free tortillas or her signature salad. And dinner is usually rice or gluten-free pasta with a lean protein like chicken or fish. Kourtney has admitted to not being much of a cook, though she does enjoy recipes out of her friend Chrissy Teigen鈥檚 Cravings cookbook (think lettuce wraps and vegetable tortilla soup).

No-Nos: Dairy, bread, and refined sugars. That means no sodas or cocktails either (though tequila on the rocks, beer, or ros茅 do make the cut 鈥 phew!)

Splurges: Gluten and dairy-free candy, and treats like pizza when in Italy or a churro at Disneyland with the kids (because vacation calories don鈥檛 really count anyway). She has also been known to eat a Kit Kat or two, but via a six-step process per individual bar that is so laborious and patience-testing that she claims 鈥測ou eat less because you鈥檙e eating it so slow.鈥

KIM: ATKINS

Tuesdaze

A post shared by Kim Kardashian West (@kimkardashian) on

Kim follows the low-carb Atkins diet. The idea behind the diet is that when you limit your carbs, your body, which usually turns carbs into fuel, will start burning fat instead. After the birth of son Saint, Kim dropped the baby weight by following the Atkins 40, a variation of the diet that allows 40g of carbs, which gave her more flexibility while she was breastfeeding. According to Kim鈥檚 nutritionist, Colette Heimowitz, Kim鈥檚 diet mainly consists of three things: protein, fiber-rich carbohydrates, and healthy fats.

Meals: Breakfast could be eggs and turkey sausage and Greek yogurt with berries. Lunch is usually a salad with grilled chicken. Dinner consists of vegetables and a protein. Snacks include Atkins bars, carrots and hummus, or fruit and cheese. And like Kourtney, Kim stays well hydrated, drinking about 48-64 ounces of water.

No-Nos: Refined sugars and carbs.

Splurges: Fast food. Kim has Snapchatted her cheat day visits to In-N-Out, where she eats a cheeseburger, cheese fries, and a vanilla shake. Although she doesn鈥檛 go regularly, she also has go-to orders at McDonald鈥檚, Chipotle, KFC, and Taco Bell. Same, Kim. Same.

KHLO脡: SEVEN MEALS A DAY

Khlo茅鈥檚 revenge body is the result of intense workouts and 鈥 count them 鈥 seven meals a day. Her nutritionist, Dr. Philip Goglia, developed a plan specific for Khloe鈥檚 body type that is a careful balance of protein, carbs, and fats. Her staples include lean proteins, veggies, fruits, and a lot of water (see a pattern here?).

Meals: Breakfast is usually a protein shake, made with protein powder, fruit, almond butter, and water. Other main meals include veggies or salad with a choice of protein (think chicken or a fatty fish like salmon or sea bass). And the other meals, which are more like snacks eaten throughout the day, are usually fruit or vegetables with some almonds or an egg.

No-Nos: Based on Khlo茅鈥檚 body type, these include dairy, diet foods, soy, juice, dried fruit, breads, and sodas.

Splurges: Khlo茅 has one cheat meal a week, which is cake, pizza, or pasta, depending on her cravings. She鈥檒l even go to Chipotle but has a healthy hack for it (it does include guac though).

KENDALL: PALEO/鈥滱NTI-MODEL鈥

A post shared by Kendall (@kendalljenner) on

When the model is prepping for fashion week or a Victoria Secret runway show, she works out every day and relies on lean proteins, vegetables, and fruit for a low-carb Paleo diet. She also drinks a ton of detox tea. On the off-season, however, she鈥檚 generally on what Khlo茅 calls the 鈥渁nti-model鈥 diet, indulging in burgers and pizza. Well, there鈥檚 good genes and youth for ya.

Another trick up her sleeve? The color pink. Kendalls鈥 living room is painted Baker-Miller pink, which in some studies has been shown to calm nerves and suppress appetite.

Meals: Breakfast could be eggs, avocado, and toast. Lunch usually includes brown rice with chicken. The home cooked dinner that Kendall says she 鈥渃ould eat for every meal鈥 is pasta and peas. Kendall also snacks on raw veggies and hummus or apples.

No-Nos:Chocolate ice cream, because she hates it (who hates chocolate ice cream?!). And pancakes, because Kendall suffers from trypophobia, a fear of irregular patterns or clusters of tiny holes, and apparently pancakes set it off. No IHOP for Kendall.

Splurges: In her dressing room, she always has Twix, Justin鈥檚 Peanut Butter, and chips and guac (and carrots and hummus, though those don鈥檛 really count as splurge foods). She also eats Frito chili cheese chips 鈥渁ll the time.鈥

KYLIE: ORGANIC / 鈥淭YPICAL TEENAGER鈥

A post shared by Kylie (@kyliejenner) on

The youngest Jenner sister follows a fresh and organic diet, but she also eats like a 鈥渢ypical teenager.鈥 It鈥檚 all about moderation. She drinks Fit Tea (and is a product sponsor), on her website claims she always has fresh squeezed orange juice in her fridge, and openly talks about her love of grapes and rice on social media.

Meals: Based on her Snaps, breakfast could be avocado toast or bacon or banana pancakes. Lunch is usually something healthy like a salad and a pressed juice. The young makeup mogul also loves to cook, so dinner could be anything from burgers to candied yams to chicken and veggies.

No-Nos: Dairy, because she鈥檚 lactose intolerant; and juice cleanses, because the last time she attempted one, she gave up after a few hours and went to go eat sushi instead. Relatable.

Splurges: Mexican food, French fries, Twizzlers, Oreos, and Hot Cheetos. Yup, typical teenager.
