Olive Oil Q&A with Dr. Sears

Today Dr. Sears is answering your questions about oils and which ones to use.

 

Q: With so many oils in the consumer marketplace, why do you consider olive oil the best of the best? 

A: Olive oil has been used for almost 4000 years and has the most clinical studies to validate its benefits. Extra virgin olive oil (EVOO), not refined olive oil, is the richest of all oils in terms of polyphenols. Most oils come from seeds, but olive oil comes from fruit. This gives olive oil a higher polyphenol content than most other oils. Also, the polyphenols in extra virgin olive are unique as they are very powerful anti-inflammatory agents that can’t be found fruits and vegetables. 

Q: What are your thoughts on some of the newer oils that have hit the market over the past few years like coconut oil, avocado oil, and nut oils? 

A: Only avocado oil has any polyphenols since it comes from a fruit. That said, the amount of polyphenols are significantly less than EVOO and lack the unique structure which gives olive oil its anti-inflammatory properties.

Q: How does someone know what to look for in an olive oil product?

A: It should taste like melted butter on the tip of your tongue but generate a very bitter taste when you flip the oil to the back of your tongue. Clarity and color are important too. If there is very little color it means the oil is refined and many of the polyphenols have been removed.

Q: Are all olive oils the same?

A: No. Authentic olive oil is very expensive to produce. What you’ll find is that some manufacturers will take olive oil and blend them with cheaper vegetable oils to dilute the olive oil and then label it as olive oil. This is why it is estimated that 70% of all olive oil in the U.S. is considered adulterated.

Q: How do you know if olive oil is adulterated?

A: It’s not always easy to tell. You have color and clarity, but this is where choosing a high-quality brand is your best guarantee of quality. When I set out to create Zone Extra Virgin Olive Oil, I sought out a few organic cooperatives in Italy known for their high quality extra-virgin olive oil.  The olives were harvested in late fall, followed by processing over the winter. Then the various processed lots were tested for polyphenol content. Those lots that met our polyphenol requirements were bottled and brought to the U.S. under the Zone brand.

Q: Is there a benefit to using organic olive oil?

A: It takes a lot of energy for plants to produce polyphenols. Once you start using pesticides to increase the production of olives, the plants generally decrease the amount of polyphenols they produce as they don't have to work as hard. This effect is more profound in fruits than vegetables. This is one benefit of using an organic oil because the polyphenol content and benefits are generally higher.

Q: What makes Zone Extra Virgin Olive Oil unique? 

A: We use an organic olive oil cooperative in Umbria, Italy where the oil is bottled on site and sent directly to us. It’s my guarantee that you are getting the best quality oil that Italy can produce that year.

Q: You mention cooking with olive oil destroys the polyphenols. Are there other oils you recommend cooking with instead since olive oil has a low smoke point?

A: Since heat destroys polyphenols the best oil to use for cooking is high-oleic safflower oil which is rich in monounsaturated fat and has a high smoke point. You could also use refined olive oil which has minimal polyphenols but good temperature characteristics. If you want to use EVOO and maximize the polyphenols it contains I recommend drizzling on top of food after its been cooked.

Q: If EVOO has polyphenols do I still need to take my polys? 

A: Yes. I recommend consuming 1000-1500mg of polyphenols per day. The polyphenols in EVOO are unique anti-inflammatory agents which can be one source, but it’s almost impossible to get that many polyphenols in olive oil alone. This is why I recommend consuming about 10 servings of fruits and vegetables per day in addition to getting polyphenols from sources like cocoa, which is good for gut health, and berries such as maqui, which activate key enzymes (AMPK) important for health.

Dr. Sears Q&A: Weight Loss

With so much interest in weight loss and so much buzz around weight loss drugs, we put together some of the top questions we get in this latest Q&A blog. Here Dr. Sears answers your questions on weight loss, weight loss drugs and what he thinks is the most scientifically backed way to lose weight. See what he has to say.Question: What medical conditions could impede weight loss, and how can they be identified?  Answer:  Any condition associated with insulin resistance will make it difficult to lose weight.  This would include diabetes, heart disease, neurological disease, etc.  Also, any drug that induces insulin resistance will also make it difficult to lose weight.  These include corticosteroids and many neurological drugs. Question: How do hormones affect weight loss, and which imbalances are most detrimental? Answer: High levels of insulin (caused by insulin resistance), high levels of cortisol (caused by stress), and low levels of satiety hormones such as GLP-1 will make weight loss difficult. Question: Is there a connection between sleep quality and weight loss? Answer: Poor quality sleep increases cortisol levels that lead to insulin resistance. The higher your level of insulin resistance, the more difficult it is for any organ to remove glucose from the blood for transport into the cell, where it can be converted to energy. This i Question: Do any weight loss supplements work?  Answer: Not really. You have to restrict calories to activate AMPK which causes your body to effectively burn excess stored body fat.   Question: What medications are FDA approved for weight loss? Answer: There are number of approved older drugs, but the most widely used is still an old drug (Phentermine) that was only recently approved for long-term use. However, the new injectable GLP-1 receptor agonists are more powerful and more popular. The scientific name for the most well-known injectable weight-loss drug is semaglutide, which is marketed under the tradenames Ozempic and Wegovy. In simple terms, these injectable drugs activate the release of the hormone GLP-1 from the gut that goes directly to the brain to tell you to stop eating. These drugs were initially developed to treat type 2 diabetes, but the clinical studies in overweight and obese individuals demonstrated significant weight loss at higher levels. Question: What are the unintended side effects of weight loss medications (i.e. GLP-1s, dual GIP/GLP-1). Answer: One major problem is that the lack of hunger caused by the drug makes you less likely to consume sufficient protein to maintain lean body mass.  Lean body mass is defined as functional tissue such as organs (including the brain) and bone.  Nearly 40 percent of the weight loss in obese patients comes from loss of lean body mass.  Without adequate protein (especially on a diet that is calorie-restricted because of lack of hunger), the replacement of damaged cells is compromised.  The skin and hair are the first site to suffer.  This lack of protein also makes it difficult to maintain mitochondrial function that provides energy for each of your 30 trillion cells. As a result, fatigue (both mental and physical) is often experienced. Question: Would you recommend an injectable weight loss drug? Answer: The answer is no. There is a big difference between weight loss and fat loss. Weight loss is the combined loss of stored body fat and lean body mass (i.e., muscle). You want to lose fat but not muscle. Although the weight loss using weekly semaglutide injections is impressive according to the literature, a deeper look shows that about 40 percent of that weight loss is due to loss of lean body mass. That is not a good sign. It suggests that the injections reduce hunger to the extent that the person has little desire to eat enough protein to maintain muscle mass. In essence, the drug increases the patients' sarcopenia (muscle loss). One of the consequences of sarcopenia is increased frailty. Also once you stop using these weight loss drugs, the weight quickly returns. Question: Does a high protein diet help with weight loss? Answer: Most high protein diets are ketogenic diets that disrupt metabolism in addition to being high fat.  The appropriate diet is protein-adequate (about 30 grams of protein at each meal), carbohydrate-moderate (primarily non-starchy vegetables, low-fat (to reduce calories) and rich in fermentable fiber.  The common name for such a diet is the Zone diet. The ideal amount of protein at each meal for weight loss is about 30 grams. Less than 30 grams of protein at meal will not generate the hormonal signals from the gut to stop hunger. Too much protein at meal, greater than 30 grams, will inhibit AMPK activity which helps cells burn excess stored fat.

Aging: Can You Slow It Down?

The first few weeks of the New Year are often focused on the resolve to lose weight, when in actuality people should focus their goals on slowing down aging, no matter the time of year. The only regimen that clinically achieves results in slowing the aging process is calorie restriction without malnutrition. Why? It’s not simply losing weight but orchestrating the complex interplay of reducing senescent cells, reprograming your metabolism, and changing gene expression, leading to a longer and better life.   A Timeline of Calorie Restriction   The first recorded human experiments with calorie restriction began with the written books of Luigi Cornaro in the 16th century, as I outlined in my book The Anti-Aging Zone, published in 1999. However, the molecular mechanisms of why calorie restriction is so effective required more recent breakthroughs in metabolism and epigenetics that were confirmed with the CALERIE study that carefully controlled the diets of 225 participants over two years and then ongoing testing of their retained blood samples.     The results of the CALERIE study have been impressive. However, the one clear take-home lesson was that reduction of insulin resistance was the most predictive blood marker correlated with the genetic changes and the decrease in senescent cells that ultimately accelerate aging.   The Zone on Calorie Restriction   The Zone diet is a calorie-restricted diet that was patented to reduce insulin resistance. It requires balancing macronutrients at each meal to generate the rapid hormonal changes that give rise to satiety. Only then can you follow calorie restriction for a lifetime without hunger and fatigue. It starts with having enough protein at each meal to create satiety in the brain's appetite control center. You need about 30 grams of protein (no more, but no less) at each meal to generate the same hormonal responses induced by the recent injectable weight loss drugs. However, you also must balance that protein with an adequate level of low-glycemic carbohydrates (about 40 grams) to stabilize blood glucose levels, and then add a dash of monounsaturated fat (about 15 grams). Over the years, it has been demonstrated by more than 40 research publications that the Zone diet is superior to ketogenic diets and the Mediterranean diet under controlled clinical research.    A New Technology to Slow Down Aging  Unfortunately, many people think the Zone diet requires too much thinking.  That’s why I developed Zone Foods to overcome that problem. The first generation of Zone Foods demonstrated dramatic reductions in insulin resistance compared to a control group, getting an equal number of calories (1). The second generation of Zone Foods offers greater variety and even more appetite suppression without thinking. This second generation will include new and improved versions of the Zone Pasta and Zone Bars, with new additions of Zone Muffins, Zone Oatmeal, Zone Granola, Zone Soups, and Zone Cookies (coming soon!). Each Zone Food contains 15 grams of protein, balanced with the appropriate level of low-glycemic carbohydrates, so any combination of two Zone Foods will provide the critical 30 grams of protein at a meal to stop hunger and maintain peak mental awareness for the next five hours. The growing variety of Zone Foods makes following the Zone diet incredibly easy. If you are never hungry, that indicates that you are reducing insulin resistance. The long-term benefit to you is slowing aging, which is only possible with lifelong use of Metabolic Engineering that starts with the Zone diet as its foundation.
