The ketogenic diet has gained significant popularity in recent years, promising sustained wellness and weight loss. Casey Thaler, a personal trainer and fitness expert, offers a definitive look at how to easily live a keto lifestyle and maximize the benefits of the Instant Pot in conjunction with this diet. This article explores the principles of the keto diet, its potential benefits, and how to integrate it with the Instant Pot for convenient and delicious meals.
Understanding the Ketogenic Diet
The ketogenic diet, often shortened to "keto," is not just a fleeting trend but a sustainable change in lifestyle backed by scientific evidence. Unlike many diets that offer short-term weight loss through restriction and suffering, the keto diet focuses on consuming healthy, substantial foods that satisfy hunger and fuel the body.
How Keto Works: Fueling with Fat
Traditional American diets are typically high in carbohydrates, which means the body primarily uses sugar for fuel. In contrast, the ketogenic diet emphasizes healthy fats and moderate protein, shifting the body's primary fuel source to fat. When the body uses fat for energy, it enters a metabolic state called "ketosis." In this state, the body and brain utilize both consumed fat and stored body fat.
The Keto Diet Food Pyramid
The keto diet encourages individuals to adjust their eating patterns to be low in carbohydrates, moderate in protein, and high in healthy fats. A general guideline is to consume 20 grams of net carbs or less per day. By adhering to these recommendations, individuals often report feeling full, satisfied, and energized.
Healthy Fats vs. Unhealthy Fats
It's crucial to distinguish between healthy and unhealthy fats on the keto diet. Processed fats like vegetable oil, sunflower oil, and canola oil can be detrimental to health. Instead, focus on incorporating sources of healthy fats such as:

The Shift Away from the 1950s Food Pyramid
In the 1950s, the prevailing dietary advice recommended a diet primarily consisting of grains (carbohydrates) with limited fats and sugar. Many people still view this food pyramid as a healthy guideline. However, the body processes all carbohydrates, including breads, pastas, cookies, cakes, and even fruits, as sugar. When there is excess sugar in the body, it is stored as fat. This has contributed to the skyrocketing rates of obesity, heart disease, and diabetes over the past 60 years. The ketogenic diet offers a potential remedy by reversing this process.
The Keto Instant Pot Cookbook: A Practical Approach
Casey Thaler's The Keto Instant Pot Cookbook provides 210 wholesome recipes that contain no processed foods, are free from sugars, and omit inflammatory grains. This cookbook bridges the gap between the keto diet and the convenience of the Instant Pot, an electric multicooker that can sauté, bake, slow cook, and pressure cook healthy, flavorful meals.
Benefits of Using an Instant Pot for Keto Cooking
The Instant Pot offers several advantages for individuals following a ketogenic diet:
- Ease and Speed: It simplifies meal preparation and significantly reduces cooking time.
- Versatility: It can be used for a variety of cooking methods, allowing for diverse keto-friendly recipes.
- Healthy Cooking: It promotes the use of whole, unprocessed ingredients.
Sample Recipes from the Cookbook
The cookbook features a wide range of recipes, including:
- Easy Healing Bone Broth
- Butter Pecan Fat Bombs
- Classic Lasagna
- Chicken Pot Pie
- Basil-Lime Carnitas
- Luscious Lemon Squares
- Soft and Chewy Chocolate Chip Cookie Bites
It also includes guest recipes from prominent figures in the paleo and keto communities, such as Danielle Walker, Dr. Kellyann Petrucci, and Robb Wolf.

The Truth About Why Keto Works: Beyond Weight Loss
Dr. Steven Gundry and Dr. Casey Means shed light on the underlying mechanisms of the keto diet, suggesting that its benefits extend beyond simple weight loss. Their discussion highlights the importance of mitochondrial uncoupling and the impact of food on overall health.
Mitochondrial Uncoupling: The Key to Keto's Benefits
Dr. Gundry's book, Unlocking The Keto Code, argues that many of the perceived benefits of the keto diet stem from mitochondrial uncoupling, a process where mitochondria (the powerhouses of our cells) become less efficient at producing energy. This might seem counterintuitive, but it can actually lead to several positive effects.
How Mitochondrial Uncoupling Works
Mitochondria turn sugars and fats into energy by creating ATP (adenosine triphosphate). However, mitochondrial uncoupling allows the body to use less energy to produce ATP, potentially leading to more work done with less effort.
The Benefits of Ketones as Signaling Molecules
Ketones, produced during ketosis, are not just energy fuels for tissues like the brain, heart, and skeletal muscle. They also act as signaling molecules, informing the mitochondria about the body's state, such as potential starvation. This signaling can trigger myogenesis, the production of more mitochondria, so each one has less work to do. It can also promote mitochondrial uncoupling.
Alternatives to Strict Keto: The Mitochondrial Uncoupling Diet
Dr. Means suggests that instead of strictly adhering to a keto diet, individuals might consider a "mitochondrial uncoupling diet." This approach focuses on stimulating mitochondrial uncoupling through various methods, not just restricting carbohydrate intake. This can allow for the inclusion of other nutrients that are beneficial for the body.

Ways to Stimulate Mitochondrial Uncoupling
Besides the keto diet, other ways to stimulate mitochondrial uncoupling include:
- Exposure to certain compounds: As observed in World War I, factory workers exposed to 2,4-dinitrophenol (DNP) experienced weight loss and increased body temperature. However, DNP can be dangerous and should not be used without medical supervision.
- Consuming MCT oil: Medium-chain triglycerides (MCTs) are absorbed differently than other fats and are quickly converted into ketones by the liver. MCT oil can be added to various foods, including fruits, to promote ketone production.
- Consuming goat and sheep milk products: Goat and sheep milk contain a significant amount of MCTs, which can contribute to mitochondrial uncoupling.
Potential Downsides of Long-Term Ketosis
While the keto diet can offer several benefits, it's important to consider potential downsides, especially with long-term adherence.
Insulin Resistance
Dr. Gundry suggests that long-term ketosis might lead to insulin resistance. This is because the body perceives itself to be in a state of starvation, and muscles, which are the biggest consumers of fuel, become the "enemy." The body may then develop insulin resistance to prevent muscles from using the fuel that the mitochondria need.
