Metabolic health is a crucial aspect of overall well-being, yet studies have shown that the majority of Americans have some level of metabolic dysfunction. A recent study by the University of North Carolina found that only 12% of the population met all the primary criteria for good metabolic health. With the impact of the pandemic likely exacerbating these numbers, it is important to understand the various factors that contribute to metabolic health.

Metabolism goes beyond simply how many calories you burn or your ability to lose weight. It encompasses all the chemical reactions in your body that contribute to energy production and utilization. Factors such as food choices, exercise, sleep, stress, and mental health all play a role in maintaining a healthy metabolism. Digestion, blood sugar control, inflammation levels, and insulin regulation are key markers of metabolic health.

Improving metabolic health involves addressing various factors, such as managing blood sugar spikes, controlling insulin levels, reducing fat in the blood, and effectively managing stress. Additionally, prioritizing quality sleep and engaging in regular exercise are crucial for maintaining a healthy metabolism. In upcoming episodes, we will delve deeper into specific conditions related to metabolic health, including heart disease, diabetes, obesity, thyroid disorders, and cancer.

Functional Nutritionist Andrea Nicholson reviews a recent study published in the American Journal of Clinical Nutrition, researchers compared the effects of a well-formulated ketogenic diet to a moderate carb Mediterranean Plus diet on individuals with prediabetes and type 2 diabetes. The diets included non-starchy vegetables, restricted added sugars, and limited refined grains. The main difference between the two diets was the inclusion of legumes, fruit, and whole grains in the Mediterranean Plus diet.

After 12 weeks, the study found that both diets led to improvements in A1c (a measure of blood sugar control) and fasting glucose levels. However, the group that started with the Mediterranean Plus diet and ended with the ketogenic diet saw the greatest improvements. LDL cholesterol increased during the ketogenic diet phase but returned to baseline levels by the end of the study. HDL cholesterol improved in both groups, with the most significant improvement during the ketogenic phase for the Mediterranean Plus group. Triglyceride levels improved in both groups, with the most significant improvement during the ketogenic phase.

Overall, the study suggests that both the ketogenic and Mediterranean Plus diets can be beneficial for individuals with metabolic diseases, emphasizing the importance of managing blood sugar and insulin. However, it is recommended to work with a healthcare professional, especially when taking medications for blood sugar or blood pressure, to ensure a safe and effective approach to dietary changes.

On this episode of the Holistic Health Bites podcast, Functional Nutritionist Andrea Nicholson talks with Heather Gray, FDN about her experience with Lyme Disease. 

Functional Nutritionist Andrea Nicholson answers common questions about stress. She emphasizes the importance of testing cortisol levels before attempting to lower them, as depleted cortisol levels can mimic the symptoms of elevated cortisol. If cortisol is indeed high, identifying the times of day when levels are elevated is crucial in determining the appropriate remedies, which may include dietary changes, lifestyle modifications, supplements, or medications.

Nicholson also discusses the relationship between cortisol and weight and overall health. Chronically elevated cortisol can lead to weight gain due to increased blood sugar and insulin levels, which result in the body storing excess fuel as fat. Furthermore, cortisol imbalances can contribute to insulin resistance, affecting various disease processes.

The effect of caffeine on cortisol is another important topic addressed. Caffeine can interact with cortisol processing in the body, causing cortisol spikes and blood sugar imbalances. However, the interaction between caffeine and cortisol is personalized to each individual, and monitoring its effects on energy levels and blood sugar with a continuous glucose monitor can provide valuable insights.

These questions and answers provide a comprehensive understanding of cortisol and stress management, highlighting the need for personalized approaches and testing to determine the most effective strategies.

Functional Nutritionist Andrea Nicholson reviews a recent study published in the Scandinavian Journal of Gastroenterology examined the effects of a fruit-rich diet on patients with non-alcoholic fatty liver disease (NAFLD). The study found that participants who consumed at least 4 servings of fruit per day gained an average of 7kg (15.4 lbs) and had increases in waist circumference, triglycerides, LDL cholesterol, total cholesterol, and liver enzymes. On the other hand, participants who consumed less than 2 servings of fruit per day lost an average of 6.5kg (14.3 lbs), had decreases in waist circumference, triglycerides, LDL cholesterol, total cholesterol, blood sugar levels, and insulin resistance. While this study focused on individuals with NAFLD, it raises questions about the overall consumption of fruit and its impact on health.

It is important to note that this study had a small sample size and there are other studies with contradictory findings. However, with NAFLD affecting approximately 1 in 3 people in the US, these results are worth considering. The study does not suggest that fruit directly causes fatty liver disease but indicates that it may worsen the condition in individuals who already have it. Considering the negative effects on cholesterol, lipids, blood sugar, and insulin resistance, it may be wise to consider reducing fruit consumption as a nutritional strategy.

While this study focuses specifically on fruit, it also raises broader questions about the role of grains and overall carbohydrate consumption in our diets. Cutting back on fruit, grains, and carbs may be worth exploring for those looking to improve their overall health.
