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.

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!

Simple Homemade Zone Meals

Simple Homemade Zone Meals

  Even people who swear by Dr. Sears' new pasta meals should create one homemade Zone meal just about every day. Cooking in the Zone isn't hard to do, especially if Zoners keep packages of frozen chopped onion and chopped peppers in their freezers. If a cup of chopped onion is needed, it's ready to go. Also keep sacks of frozen vegetables, including broccoli florets, handy.   Here are some meals, shown for both women and men, that are a snap to make for people on the go.   Ginger Chicken Ingredients:   Dinner for women 1 teaspoon olive oil 3 ounces boneless, skinless chicken breast 2 cups broccoli florets 1 ½ cups snow peas ¾ cup yellow onion, peeled and chopped 1 teaspoon fresh ginger, grated ¼ cup water ½ cup seedless grapes Dinner for men 1 1/3 teaspoons olive oil 4 ounces boneless, skinless chicken breast 2 cups broccoli florets 1 ½ cups snow peas ¾ cup yellow onion, peeled and chopped 1 teaspoon fresh ginger, grated ¼ cup water 1 cup seedless grapes Directions: In a wok or large nonstick pan, heat oil over medium-high heat. Add chicken and saute, turning frequently, until lightly browned, about five minutes. Add broccoli, snow peas, onion, ginger and water. Continue cooking, stirring often, until chicken is done, water is reduced to a glaze and vegetables are tender, about 20 minutes. If the pan dries out during cooking, add water in tablespoon increments to keep moist. Serve grapes for dessert or garnish dish with grapes. Salmon Patties Ingredients:   Dinner for women 3 ounces canned pink salmon 2 egg whites 1/3 cup slow-cooking oatmeal, cooked Quarter of an onion, diced 1 teaspoon dill Garlic salt and pepper 1 teaspoon refined olive oil ½ apple Dinner for men 4 1/2 ounces canned pink salmon 2 egg whites 1/3 cup slow-cooking oatmeal, cooked Quarter of an onion, diced 1 teaspoon dill Garlic salt and pepper 1 1/3 teaspoons refined olive oil 1 apple Directions: Flake salmon in a medium bowl. Combine all ingredients except olive oil and mix well with hands. Heat olive oil in pan at medium heat. Shape mixture into a patty and cook for about three to five minutes on each side (or until golden brown). Serve immediately. Have apple for dessert. Tuna and Three Bean Salad Ingredients:   Dinner for women 3 ounces canned tuna ¼ cup kidney beans, canned, drained and rinsed ¼ cup garbanzo beans, canned, drained and rinsed ¼ cup black beans, canned, drained and rinsed 1 teaspoon olive oil Rice vinegar to taste 1 teaspoon onion powder or to taste ¼ teaspoon garlic powder or to taste Bed of lettuce Dinner for Men 4 ounces canned tuna ¼ cup kidney beans, canned, drained and rinsed ¼ cup garbanzo beans, canned, drained and rinsed ¼ cup black beans, canned, drained and rinsed 1 1/3 teaspoons olive oil Rice vinegar to taste 1 teaspoon onion powder or to taste ¼ teaspoon garlic powder or to taste Bed of lettuce ½ apple Directions: Mix together tuna and beans. Whisk together olive oil, rice vinegar, onion powder and garlic powder. Pour over tuna mixture and toss. Serve over a bed of lettuce. Have fruit for dessert. Chicken and Green Beans Italian Style Ingredients:   Dinner for Women 1 teaspoon olive oil 3/4 cup onions, chopped 1 14.5-oz can diced tomatoes 1 teaspoon bay leaf (1 small) Italian seasoning to taste Salt and pepper to taste 3/4 cup green beans cut into 1-inch pieces 3 ounces precooked chicken Dinner for Men 1 1/3 teaspoons olive oil 1 1/2 cups onions, chopped 1 14.5-oz can diced tomatoes 1 teaspoon bay leaf (1 small) Italian seasoning to taste Salt and pepper to taste 1 1/2 cups green beans cut into 1-inch pieces 4 ounces precooked chicken Directions: Cook the green beans to your liking - boil or steam.
