***Top 5% Globally Ranked*** Trying to Fix Insulin Resistance? Understand This Before Choosing a Diet

Are you trying to improve insulin resistance but feel pressured to choose the perfect diet? Keto, Mediterranean, vegetarian, and low-carbohydrate eating are often presented as competing choices—but improving metabolic health begins with understanding what food does inside your body.

In Episode 36 of Health Beyond Weight Loss, TaShawn Davis, RN, explains insulin resistance, ketosis, blood sugar regulation, and how cells use different fuel sources. She also clarifies the difference between a dietary pattern and a metabolic state, helping listeners understand why they do not have to choose a label before beginning their health journey.

This episode is for anyone experiencing fatigue, cravings, difficulty losing weight, blood sugar concerns, or confusion about which nutrition approach may support better metabolic health.

In This Episode

• What insulin resistance means in simple language

• Why blood sugar can appear normal while insulin levels are elevated

• The difference between keto, Mediterranean, vegetarian, and low-carbohydrate eating

• Why ketosis is a metabolic state—not simply a diet label

• How the liver produces ketones

• How cells use glucose, fatty acids, and ketones for energy

• The difference between nutritional ketosis and diabetic ketoacidosis

• Why food quality and individual response matter

• What research is showing about ketosis and brain health

• How ketogenic dietary therapy has been used in certain seizure disorders

• Why metabolic health is about more than weight loss

• How to begin paying attention to your body’s responses to food

What Is Insulin Resistance?

Insulin helps move glucose from the bloodstream into the cells. When cells become less responsive to insulin, the pancreas may produce more insulin to maintain blood sugar control.

This compensation can occur before prediabetes or Type 2 diabetes is diagnosed. Insulin resistance may be associated with cravings, fatigue, abdominal weight gain, high triglycerides, fatty liver, and difficulty losing weight—but symptoms alone cannot diagnose the condition.

Understanding insulin resistance can help people ask better questions and have more informed conversations with their healthcare professionals.

What Is Ketosis?

Ketosis is a metabolic state that occurs when the body has less available glucose and begins producing ketone bodies from fat. These ketones can be used by tissues throughout the body, including the brain.

This is different from diabetic ketoacidosis, a dangerous medical emergency. Nutritional ketosis should not be confused with diabetic ketoacidosis, and people with diabetes or complex medical conditions should seek individualized medical guidance before making major dietary changes.

Key Takeaways

1. You do not have to choose a diet label before you begin improving your health.

2. Keto, Mediterranean, vegetarian, and low-carbohydrate describe eating patterns; ketosis describes a metabolic state.

3. A vegetarian diet is not automatically metabolically healthy, and a ketogenic diet is not automatically healthy simply because it is low in carbohydrate.

4. Insulin resistance may develop before blood sugar becomes clearly abnormal.

5. Ketones can provide another fuel source for the body and brain.

6. Research findings must be interpreted carefully; promising results do not automatically prove a cure or guarantee individual outcomes.

7. Food quality, nutrient density, medical history, medications, and individual response all matter.

8. Understanding your body can help you mak
