In the ever-evolving world of diet trends, the ketogenic (keto) diet and the Whole30® program frequently emerge as popular choices. Both encourage the adoption of new eating habits, but significant differences exist. This article provides a detailed comparison to help you make an informed decision.
Understanding the Ketogenic Diet
The ketogenic diet, often shortened to "keto," is a high-fat, very low-carbohydrate diet designed to shift the body's primary fuel source from glucose to fat. This metabolic state is known as ketosis.
How Keto Works
A "true" keto diet severely restricts glucose sources, compelling the body to burn fat for energy. When fat is broken down, fat cells release ketones into the bloodstream. This elevation of blood ketones lowers the blood's normal acid-base balance, leading to a more acidic state, or ketosis.
Typically, a keto diet plan derives approximately 70% to 75% of daily calories from fat, 20% from protein, and no more than 10% from carbohydrates.
The Keto Diet: A Historical Perspective
The keto diet isn't a new trend; it was introduced in the 1920s. Originally, it was used to help people who suffer from seizure disorders-not as a weight-loss plan.

Foods to Eat and Avoid on Keto
Following a keto diet requires you to rethink some of the ingredients in your pantry.
Foods to enjoy:
- Lean meats (chicken, grass-fed beef)
- Fish
- Eggs
- Healthy fats (like olive oil, avocado, and even butter)
- Leafy greens
- Non-starchy veggies
- Some dairy
Foods to avoid:
- Grains
- Beans
- Legumes
- Sugar
- Milk
- High-carb options
- Fruits (limited)
Potential Benefits of the Keto Diet
- Weight Loss: A keto diet can help you lose five to 10 pounds or more, jump-starting a weight-loss program. Many people who follow this diet boast dramatic weight loss.
- Medical Applications: In addition to helping treat seizures, the keto diet can be beneficial for other medical conditions, such as Type 2 diabetes. Ketogenic diets can cause serious drops in blood sugar and insulin, which is why some people living with diabetes turn to the diet.
- Reduced Appetite and Brain Fog: Many followers say it helps reduce their appetite and eliminate brain fog.
Potential Drawbacks and Risks of the Keto Diet
- Increased LDL Cholesterol: The downside, even for the short term, is a potential rise in LDL (bad) cholesterol.
- Nutrient Deficiencies: Fruits, grains, and legumes are off limits, as are many vegetables. Therefore, your body might not get enough nutrients if you follow the diet for a long period of time.
- The "Keto Flu": New dieters commonly experience this as the body gets used to the new way of eating. Keto flu symptoms may include muscle soreness, digestive upset, nausea, low energy, and dizziness.
- Health Concerns: There are some studies that suggest the keto approach isn’t right for the long term and can cause cardiovascular and liver risks. Keto diets are not recommended for people who've had kidney or liver issues. And it's still unclear what the long-term health consequences of the diet are.
- Restrictiveness: The keto diet is more restrictive than other low-carb diets. Followers must track carb levels and ketone levels to ensure their bodies go into ketosis, or the process that makes ketones. Eating something carb filled can cause your liver to stop making ketones.
Practical Tips for Keto
- Rethink Snacking: Between-meal noshing is largely off-limits on keto. If you’re in the state of ketosis, you likely won’t feel as hungry throughout the day. However, if you do need a snack, choose wisely-snacking may spike blood sugar levels, which may bring you out of ketosis.
- Stock Your Pantry: Like many diet plans, keeping the right foods in the house (and ditching the temptations that’ll derail your health goals) can go a long way to help you stick with it.
- Read the Menu: When dining at a restaurant, be on the lookout for hidden carbs.
- Easy keto recipes: will be your best friends as you navigate a low-carb lifestyle.
Exploring the Whole30® Program
Unlike the keto diet, Whole30® is a short-term program that lasts for only 30 days. It focuses on how your body responds to the changes you’re making and avoids inflammatory foods such as grains, dairy, legumes, soy, sugar, and artificial sweeteners.
How Whole30® Works
Cutting out sugar, grains, dairy, and more, is supposed to help you make healthier food choices and nix bad eating habits (like junk food binges). And after the allotted 30 days, you’re supposed to slowly reintroduce food groups so you can pinpoint any ingredients that might be causing certain issues (pain, GI distress, acne, you name it).
Foods to Eat and Avoid on Whole30®
Foods to enjoy:
- Whole, fresh foods like fruits
- Vegetables (including starchy veggies like potatoes)
- Chicken
- Fish
- Eggs
- Healthy fats
Foods to avoid:
- Alcohol
- Grains
- Legumes
- Dairy
- Sugar or artificial sweeteners
- Soy
- MSG
- Processed snacks
- "Comfort" foods like pancakes or desserts.
Potential Benefits of Whole30®
- Resetting Eating Habits: Whole30 doesn’t boast dramatic weight loss results. It focuses on healthy eating habits and learning to work whole foods into your diet.
- Identifying Food Sensitivities: After completing the Whole30 diet, you may finally discover the hidden culprits behind your health woes.
- Improved Health Markers: During the 30-day Whole30 plan, you may find that your skin is clearer, your sleep is deeper, your mental focus is better, or your tummy is flatter.
- Developing Disciplined Eating Habits: The Whole30 offers the chance to gain self-awareness and to develop disciplined eating habits.
Potential Drawbacks and Risks of Whole30®
- Elimination of Healthy Foods: A major drawback to this diet is that it eliminates whole grains entirely. Whole grains are a large source of fiber as well as other vitamins and minerals. But it also cuts out all grains, all legumes, and all dairy, which are healthy foods and a good source of vitamins, minerals, fiber, and protein to one’s diet.
- Strict Adherence: Another disadvantage is there are no “cheat” days. If you slip up and eat an unapproved food, then you’re supposed to start back at day one.
- Risk of Disordered Eating: With elimination diets, there may be cause for concern regarding the risk of developing disordered eating habits, so be honest with yourself and evaluate whether a strict elimination diet is the right move for you.
- Sustainability: It’s important to note that it’s a 30-day program, so it’s not going to support sustainable weight loss unless you keep elements of it intact after the 30 days.
Practical Tips for Whole30®
- Nix Temptations: Sometimes when you start a new diet (like low-sugar or gluten-free), you quickly look for recipes to recreate favorite treats. Not on Whole30®! According to Urban, this approach misses the point.
- Put Your Scale Away: No need to weigh yourself while following Whole30®.
- Limit Snacks: Just like keto, a Whole30® diet recommends limiting snacks.
- Get Cooking: For both diets, cooking from scratch can help you stay on track and control your ingredients.
Keto vs. Whole30®: Key Similarities and Differences
To summarize, here are the major similarities and differences between the keto diet and the Whole30® program:
Similarities
- Restrictive Nature: They’re both restrictive in some ways, whether it’s limiting a macronutrient or entire food groups.
- Difficulty: They can be tough to follow.
- Low-Carb Element: Both diets have a low-carb element.
- Junk Food Elimination: They tend to weed out junk food.
- Added Sugar Restriction: They cut out added sugar.
Differences
- Fat Intake: You don’t have to eat as much fat on Whole30 as you do on keto.
- Fruit Consumption: Whole30 wants you to eat fruits, while keto limits them.
- Starchy Vegetables: Starchy veggies like potatoes are encouraged on Whole30; Keto largely avoids them.
- Alcohol Consumption: The keto diet is okay with alcohol, but Whole30 discourages drinking.
- Artificial Sweeteners: You can have artificial sweeteners on keto, but not on Whole30.
- Duration and Lifestyle: Keto is considered a lifestyle. Whole30, on the other hand, is more of a 30-day cleanse.
- Dairy Consumption: Dairy is off-limits on Whole30, but it’s fine on keto.
Which Diet is "Better"?
Both diet plans are restrictive, which nutritionists aren’t exactly thrilled with.

That said, Whole30 seems to come out on top. Whole30 “doesn’t restrict an entire macronutrient, but food groups, which may be more realistic,” says Beth Warren, RD, founder of Beth Warren Nutrition and author of Secrets of a Kosher Girl. Keatley agrees: “Whole30 is closer to a generally healthful diet then keto,” he says. “The goal of cutting out some sugar from our diet is welcome for most people, but the proper adding back of foods following the 30 days is key.”
Additional Considerations
- Paleo Diet: The paleo approach centers on the unprocessed, truly natural foods humans consumed through hunting and gathering in the Paleolithic era, which ended about 10,000 years ago. A paleo diet can be ketogenic if simple carbs are limited enough.
- Carnivore Diet: A carnivore diet is the most ketogenic because its carb content is extremely low, which is why it's sometimes called the "zero carb" diet.
