Dr. Sears Answers Your Weight Loss and Plant Based Questions

From Weight Loss to Plant Based, Dr. Sears is answering your questions. See some of the latest  customer submitted questions and what Dr. Sears has to say in his latest blog. 

 

Q: What would you say are some of the most common dieting mistakes that make it harder to lose weight?

 A: The biggest mistake is not addressing the underlying cause of weight gain which is increased insulin resistance.  Reducing insulin resistance requires a different dietary strategy than simply reducing calories.  You have to activate the master regulator of metabolism which is AMPK.  To do so cutting back on calories has to be supplemented with omega-3 fatty acids and polyphenols, both of which activate AMPK. The combination of the three dietary strategies is the best long-term way to reduce insulin resistance.

 Q: How do these habits make weight loss difficult or lead to weight gain? 

A: Getting adequate levels of omega-3 fatty acids will likely require supplementation.  Getting adequate levels of polyphenols will require consuming far more non-starchy vegetables and fruits than most Americans currently do. Alternatively, one can use polyphenol extracts. 

 Q: What tips can you offer for breaking these habits/creating healthier ones? 

 A: Realize that reducing calories must be followed on a lifetime basis to be successful.  Adding omega-3 fatty acids and polyphenols can increase dietary compliance by their activation of AMPK.  This supplementation with omega-3 fatty acids and polyphenols will not only burn fat faster but also reduces insulin resistance which is the underlying cause of weight gain in the first place.

Q:  What are the best metabolism-boosting foods to put on your plate every day? How do these foods help boost your metabolic rate? How can this help aid weight loss?

A: The cause of a slow metabolism is a condition known as insulin resistance. The molecular mechanism of insulin resistance is the inhibition of AMPK, which is the master regulator of metabolism in every cell.

To speed up metabolism, you must activate AMPK. One class of nutrients that activates AMPK are polyphenols. These are found in low concentrations in fruits and vegetables. The more colorful the fruits (like berries) or vegetables (like artichokes) the more polyphenols. Unfortunately, you need to consume about 10 servings of such polyphenol-rich fruits or vegetables per day to get enough to activate AMPK. However, any AMPK-activating properties of polyphenols can be inhibited by consuming excess calories or glucose. So, to speed up your metabolism, you need to consume a calorie-restricted diet low in low in starches (bread, pasta, rice, and potatoes), and rich in fruits and vegetables.

 Q: More and more people are going plant-based for various reasons whether it’s health, animal welfare, trying to reduce the carbon footprint etc. A recent study showed that a diet rich in healthy plant-based foods may lower the risk of breast cancer but not if that diet is high in unhealthy foods, particularly juice and chips. What are your thoughts on plant-based diets and how they may impact cancer risk?

A: A plant-based diet is lower in branched-chain amino acids. Branched chain amino acids can activate the gene transcription factor mTOR which promotes tumor growth, so moderating your intake of branch chain amino acids can help minimize cancer risk. As this study points out, it makes no sense to consume a plant-based diet rich in unhealthy foods. Foods rich in processed carbohydrates are high in glycemic carbohydrates which promote insulin secretion and can activate the IGF-1 pathway that also activates mTOR. Since cancer can be considered an inflammatory disease, you must follow an anti-inflammatory diet to have the maximum effect on reducing cancer development.  Such a diet is calorie-restricted but rich in omega-3 fatty acids, and polyphenols all of which activate AMPK that inhibits mTOR in addition to optimizing immuno-metabolism to better eliminate cancer cells.

 Q: For vegetarians it’s a bit easier to find non-animal protein sources but for vegans trying to find adequate protein sources that are low-glycemic can be challenging. Which sources do you recommend?

 A: I think the better choices for vegans that are lower glycemic are tofu, tempeh, seitan and for those trying to minimize soy intake, supplementing with a pea protein powder. Also increasing intake of higher protein vegetables like asparagus, broccoli, Brussel sprouts, cauliflower, and mushrooms to name a few can aid fewer carbohydrates to your meal in addition to being great sources of fermentable fiber and polyphenols.

Tofu: Tips and Recipes Ideas

I have been eating tofu for a very long time, much longer than the 30 or so years I have been following the Zone Diet. Back then many of my favorite recipes came from the Tassajara cookbooks by Edward Espe Brown, the celebrated chef from the kitchen at California’s famous Zen Mountain Center, and cookbooks by Louise Hagler, a.k.a. Wendy Louise, a well-known authority on vegetarian cooking who is associated with a community in Tennessee known as The Farm. Those books are still among the best resources for tofu recipes. My mantra has always been if you don’t like something, don’t eat it. Keep this in mind if you’re new to tofu, start slowly by combining it with flavors and foods you like.    Tips and Suggestions    Firm-sprouted tofu is my preference for the Zone Diet. Unlike traditional tofu, which contains significant amounts of both protein and carbohydrate, sprouted has almost no carbohydrates. It’s lighter tasting, refreshing, and very filling.   Freezing tofu results in a chewy, sponge-like texture. I don’t recommend freezing, but some people prefer it when using tofu to substitute for meat in a recipe.    Baked tofu comes in a variety of flavors and makes an excellent quick meal with some vegetables and fruit added. It’s also great in salads.     Tofu made it into the book “The Top 100 Zone Foods” by Barry Sears.    Some recipes call for draining the tofu first. I find that usually isn’t necessary.   Tofu takes on the flavor of whatever is added to it.    Add nutritional yeast flakes to give a cheesy flavor to vegan tofu scrambles and dips. It’s also rich in protein and vitamin B12.   Cherry Vanilla Tofu “Ice Cream”   Tip: This doesn’t freeze or store well, so prepare only the amount you plan to serve immediately.   Using an immersion blender or a food processor blend equal parts of frozen dark cherries and firm tofu, plus some vanilla extract (preferably alcohol-free for best flavor). Serve immediately.  Tofu Scramble  This is great for breakfast, lunch, or dinner, and we’ve even brought it on long day hikes for a snack.   Crumble some firm tofu and stir in a generous amount of seasonings, taking care not to overdo it with the salt. Heat in a well-seasoned or nonstick skillet with a little Zone-friendly oil to the desired doneness.    Optional: If time allows, sauté some chopped onion in the skillet before adding the tofu and seasonings.    My favorite seasoning combination for this dish at my house is onion powder, garlic powder, turmeric, paprika, some oregano or thyme, nutritional yeast flakes, salt, and ground black pepper. The yellow color of the turmeric makes it somewhat like scrambled eggs.   Tofu Veggie Almond Pasta Salad   Dressing: Thin some smooth almond butter by stirring in some water, a little vinegar, and either soy sauce or Bragg’s Liquid Aminos (an unfermented soy sauce found in the health food section of most grocery stores).    Toss together cooked Dr. Sears’ Zone PastaRx Fusilli, tofu cut into cubes, matchstick cut red bell pepper, chopped green parts of scallions (a.k.a. green onions), and the almond butter dressing. Serve immediately or chill to serve later. It will keep well in the fridge for two or three days.   Use your imagination and see what you can come up with.  Experiment and have fun with it. Try using tofu to make cheesecakes, whipped desserts, tofu chocolate pudding, tofu “cream” based soups, tofu pot pie (think chicken pot pie), tofu burgers, tofu burritos, Buffalo tofu (like Buffalo wings), layered Mediterranean dips, tofu “meatballs”, grilled tofu, and more.    Enjoy!
