“Watching” Your Diet and Workouts

/in /by

While the strategy for eating less I described on Tuesday used no type of tracking, this story is going to be the opposite. I ran into another person who has spent a couple of years focused on getting to a normal body weight. A couple of injuries playing sports set him back a little, but as we talked and I relayed the story from the day before, he said he was just the opposite: he tracks everything on his watch.

He records every meal—including the fast food breakfast sandwich he was eating; a client had brought it in and he felt he needed to explain his food choice to me. Remember, every food is acceptable as long as you track the frequency and amount. He continued that he tracks every workout—two days running, two days swimming, a spinning class, and he tries to run over the weekend. He can chart just about everything to monitor progress. He’s reached his weight-for-height goal and intends to keep up the lifestyle, because now, it’s his lifestyle.

Two different people, two different approaches—both worked. I’ll bet you have a story yourself. If not, you can write yours now, this year in 2025, so you can share it. It may inspire others. If you have one that’s worked for you, let me know how you did if you want me to share it with our group. Science takes you only so far; it’s how you make science work for you that’s important. Eat better. Eat less. Move more. And do it your way.

“I’ll Have What She’s Having”

/in /by

My philosophy of getting to a normal weight and staying there is to find out what works best for you by trial and error. When you find something that works, stick with it. This week, I’m going to relay the conversations I had with two people within 24 hours and how they approached weight reduction.

I recently saw a physician I hadn’t seen in three or four months, and I noticed he appeared to have lost some weight. I commented that he looked leaner than the last time I saw him. Many people ask how a person lost the weight, but I think that’s a personal thing; if someone wants to share it, great. Evidently he decided he’d share it.

He knew that he was way over his weight for height based on BMI; he also relayed the fact that he didn’t want to track his calories. What he decided to do was to eat the way his wife ate. She’s about 5’ 1” tall and weighs 110 pounds; she’s always maintained that weight with no effort. He decided to eat the food that she ate in the serving size that she ate. I’d never heard that from anyone before, and I thought it was brilliant. The result of following that pattern over a number of months was that he had lost 45 pounds and still had about 15 pounds to go to get to his normal weight for height.

When a couple do things together, it can make things so much easier, but it doesn’t have to be a couple. If you can observe people who appear to be lean and a normal body weight, just watch the amount of food they eat as well as the types of food they eat. It always comes down to eat less, eat better, move more. As I said when I started, we just have to figure out how to do that for ourselves to find out what works best. Next story on Saturday.

From Polypharmacy to the Natural Way

/in /by

When last we left our subject, he had a stent inserted while having a heart attack and was sent to cardiac rehab. He was on six medications (the very definition of polypharmacy) for congestive heart failure, A-fib, and hypertension. He decided that he wanted to get off all the medications he could because they contributed to him feeling weak, with no energy and a foggy brain.

The wellness center he went to had a strong nutrition-education program so while he was exercising, he was learning how to eat. The diet? As much as her wanted of raw, baked, and steamed vegetables; limited amounts of grains, beans, seeds, nuts; no meat. No SOS—that stands for sugar, oil, or salt.

The results? In five months, he lost ten pounds, but that wasn’t a goal. He reduced medications from six to two and will stop another when he’s a year out from his stent. He has normal sinus rhythm, normal blood pressure, and no signs of congestive heart failure. He states that his diet compliance isn’t perfect, but since following the nutrition approach, he has no brain fog, lifts weights, and runs on a treadmill. He wakes up every day with energy.

If you want to really get off medication for cholesterol, BP, and other associated conditions, that’s the natural way. It must be done under supervision and with your physician’s guidance. This man was fortunate that he could afford to participate in the in-patient program where he continued to learn, but many people have done it without an in-patient experience. This case report says it can be done and outlines the way. The effort is up to you.

The Kids’ Top Health Issues webinar on January 26 still has openings. I’ll cover the question I get asked most often in detail: constipation. Reserve your spot today.

Here’s a New Term: Polypharmacy

/in /by

Polypharmacy is defined as the use of multiple or unnecessary medications.  One of the questions I often get goes something like “How do I get off all these medications my doctor has me on?” Another related question is “I don’t want to take medications—I want to do things the natural way.” These are valid goals, but it may not be easy.

Because of the nature of some conditions, there may be no other way. But when it comes to heart disease, type 2 diabetes, and hypertension, there may be a lot you can do, and thereby hangs a tale.

Several years ago, an 82-year-old man had been living with several heart issues: coronary artery disease, elevated cholesterol levels, high blood pressure, and persistent atrial fibrillation. With multiple medications to control symptoms and treat the conditions, he was a poster child for polypharmacy. He was admitted to a hospital while having a heart attack. The surgeon opened the artery, more medications were added, and he was released. On his follow-up, he was not feeling well, weak, and had periods of brain fog. He was referred for cardiac rehabilitation.

At some point, he decided that he wanted to reduce his medications. Together with a wellness center and under the supervision of his physicians, he changed his diet; on Saturday, I’ll tell you what happened over the next six months.

The Kids Top Health Issues webinar on January 26 still has openings. Every day, more scary headlines cast doubt on science and health practices. For example, will fluoride really impact a child’s IQ? Those questions and more will be covered in this webinar. Reserve your spot today.

Blue Zones: Eat Reasonably

/in /by

As I continued to consider the four areas that make up the health habits related to living to 100, I would have thought that nutrition was going to be the key. After much reflection, it’s not. However, it doesn’t mean you should live on a diet of sweets, deep-fried foods, and a lot of ultra-processed foods.

Eat a Selective Plant-Based Diet

Do I mean you have to be a vegan? No. But as North Americans, we just don’t eat very many minimally processed vegetables. By minimally processed I mean you cut them up, season to taste, and cook. It can be stews, soups, side dishes, or whatever.

While the types of plant-based foods vary by culture, there are several foods in common:

  • Beans, lentils, and nuts of all types are an important source of fiber and protein. Soups and salads are perfect delivery systems, but so is chili—as spicy as you like it.
  • Root vegetables are important: potatoes, especially sweet potatoes and yams, carrots, and purple yams called ube.
  • Green, leafy vegetables: lettuces, cabbages, and greens of all types, such as coleslaw or collard greens with bacon. Eat some every day.
  • Lean meats for additional protein.
  • Wine, if you drink it, even though it’s a processed grape.

Make those the foundation of your diet along with healthy oils such as olive oil and some whole grains, and that’s it. Remember, this isn’t a weight loss program; it’s a way to eat for life.

Two More Important Points

Don’t overeat. Eat just enough and no more. The Okinawans eat to feel 80% full and that’s where they stop.

Get to a normal body weight, no matter what it takes or how long it takes, and stay there. It’s easier to move around if you’re leaner, and you’ll have fewer complications of degenerative disease.

The Bottom Line

What you eat is important to live well, whether to 100 or not. It’s not difficult, but it may force you to think about how you can do that until it becomes a habit. The sooner you figure that out, the more time you get to live well. Next week I’ll finish this up with the most important secret of living to 100, Blue Zones or not. It surprised me.

Make Every Bite Count

/in /by

You’re eating vegetables, fruit, whole grains, dairy, proteins foods, and oils, and you’re staying within calorie limits for a healthy BMI. Does this sound abnormal to you? Sure, we can quibble about the need for dairy or the percentage of carbohydrates, but the Dietary Guidelines for Americans (DGA) are reasonable, and they’re almost exactly the same as when they were first written almost 50 years ago.

Is there a recommendation to “make sure you eat every cookie, candy, pie, and pasta in mass quantities every day” anywhere to be found? No. Is this a responsible approach to get the nutrients you need? Yes. The guidelines also recommend foods that are specific to cultures and ethnic groups and a variety of cooking styles.

Compare that with the keto recommendations of severely restricting carbohydrates, or veganism restricting animal products of any types, or the paleo diet restricting every grain for some unverifiable theory about what people ate in the Paleolithic era. Which sounds stranger to you now?

DGA Limitations

The DGA also includes these recommendations:

  • Added sugars: Less than 5% of calories per day starting at age 2. Avoid foods and beverages with added sugars for those under 2.
  • Saturated fat: Less than 10% of calories per day starting at age 2.
  • Sodium: Less than 2,300 milligrams per day, and even less for children younger than 14.
  • Alcoholic beverages: Adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to two drinks or less in a day for men and one drink or less in a day for women, when alcohol is consumed. Drinking less is better for health than drinking more.

The Bottom Line

Is there a lot to criticize about the DGA? Not really. Most people who do are actually criticizing the Western-style diet and the food selections people make when eating that way. Nowhere does it say that we should eat ultra-processed foods to fulfill the carbohydrate recommendations. As I’ve said, I like Cheetos and peanut butter cookies about as much as the next person, but those are not something to eat on a regular basis. As the occasional snack in small amounts, sure. But as a regular part of the diet? No. The guidelines can recommend, but they can’t control manufacturers to the extent that they produce only foods that fit within the DGA. That choice on how to follow the guidelines is laid upon your shoulders for you and your family.

Now that you know what the guidelines actually say, maybe you can make better decisions about what you want to put into your body and in what quantity. Remember the tag line of the DGA? Make every bite count. Your body, your choice.

What Are the Dietary Guidelines for Americans?

/in /by

“Make every bite count.” You might think that phrase came from one of the many nutritional gurus on the Internet or in the thousands of books written about the best way to eat. Fact is, that’s the tagline from the USDA Dietary Guidelines for Americans 2020-2025 (DGA). Do you know what’s contained in those guidelines? We often see criticism of the DGA by those gurus, but they seem to be obsessed only with the supposed high carbohydrate levels and how bad that is for us. I thought we should review the guidelines so we understand the facts.

The most important change I see is an emphasis on nutrition in a baby’s first year and then at various life stages. The main focus, whatever the age group, is to focus on meeting food group needs with nutrient-dense foods and beverages, and stay within calorie limits. Two concepts there that we shouldn’t miss: food first and don’t overeat for your health and activity pattern. A healthy dietary pattern consists of the same nutrient composition in the foods and beverages across all food groups, in recommended amounts, and within calorie limits.

Here are the core elements that make up a healthy dietary pattern:

■  Vegetables of all types: dark green; red and orange; beans, peas, and lentils; starchy; and other vegetables

■  Fruits, especially whole fruit

■  Grains, at least half of which are whole grain

■  Dairy, including fat-free or low-fat milk, yogurt, and cheese, and/or lactose-free versions and fortified soy beverages and yogurt as alternatives

■  Protein foods, including lean meats, poultry, and eggs; seafood; beans, peas, and lentils; and nuts, seeds, and soy products

■  Oils, including vegetable oils and oils in food, such as seafood and nuts That’s it. Sounds reasonable to me—how about you? I’ll talk about what is unreasonable and the most important recommendation of the DGA on Saturday.

Phytonutrients: Diet or Supplements?

/in /by

The study that we looked at this week demonstrated that flavonoid intake is related to socioeconomic status. It also demonstrated that most of that difference comes from the consumption of tea. All well and good.

What stood out to me was the lack of phytonutrient intake. While there were some small differences in the other flavonoids besides flavan-3-ols, the total intake of flavonoids was low. Even though we’re talking about just one class of phytonutrients, the total flavonoid intake minus the flavonoids from tea was about 140 milligrams per day. That’s reflective of a poor diet that does not include as many sources of phytonutrients as it should: not enough vegetables, fruit, beans, nuts, and others. And it hasn’t changed in the six years of the study. Most people still don’t eat enough plant-based foods to do themselves any good.

Supplements: An Insurance Plan

The study demonstrated the need for the regular use of supplements containing plant concentrates. A plant concentrate is the plant or its fruit or its root or its leaves, minus the water and the fiber. It should also have been harvested at the peak of nutrition, not the peak of flavor and taste. The plant concentrates contain all the phytonutrients that are contained within the plant, and that includes not only the flavonoids that were the subject of this study, but all of the other types of phytonutrients that we need on a regular basis.

The plant concentrates may be found in multivitamin-minerals, as part of a fruit-and-vegetable concentration, or maybe even as a stand-alone. We’re not talking about treating diseases with these supplements; we’re talking about getting the nutrition that you’re supposed to be getting from the foods that you eat (but you’re not). To me, this study pretty much proves that everyone needs to take supplements with plant concentrates every day. They provide good backup while you work on improving your diet.

The Bottom Line

If you want the best chance at preventing degenerative diseases, you need optimal nutrition. That starts with what you eat, including all those phytonutrient-containing vegetables, fruits, beans, grains, and aromatic herbs used to season your food. As a backup, take supplements that contain plant concentrates to complement your diet. It’s not either/or; it’s using them both to get to better health.

Paula and I will be taking some time off to work on more jobs around the house. We’ll be back after a short break.

Can Fasting Reduce Inflammation?

/in /by

In this Memo, I’ll review the third paper from the recent journal Cell on fasting and summarize what this all may mean for the use of intermittent fasting.

Researchers used both mice and humans as subjects in a series of studies. The objective was to examine how the immune system responded to a fasting protocol. For the study in humans, the subjects fasted for 19 hours after eating, with blood samples taken before and after the fast. In the mice, a variety of protocols were used. The most common was mice were fed for a short time before food was withheld for the remainder of 24 hours.

In mice and humans, circulating monocytes were reduced. This was important because they were pro-inflammatory in nature; thus inflammation decreased in response to the fasting protocol. In some of the studies, this reduction was maintained even with exposure to pathogens. That means the immune response was not compromised even in animals with induced autoimmune diseases.

Fasting Protocols

Three different studies used at least three different approaches to fasting. In the first study, food was withheld completely for 36 hours. In some phases of the second study, calories were reduced by 50% although the vitamins, minerals, and protein were maintained at normal levels. The final study used a fasting protocol we’re most familiar with: eat within a few hours and liquids only the remainder of the day.

The results were similar in sustaining and perhaps improving the immune system of the animals when placed under pathogenic stress. The only issue is what form of dietary restriction worked best? You can’t ask mice how they felt; you can only check immune system markers. In one of the approaches, the skin of the mice was injured at different times of continued fasting. The healing ability continued until the fast went beyond 48 hours; after that wound-healing was impaired.

The Bottom Line

These studies haven’t changed my approach to fasting. If you’re going to fast to rejuvenate your immune system, don’t play games. Reduce caloric intake to 500 to 800 calories per day for two to three days; those studies show the best benefit. Be sure to select small quantities of the healthiest foods.

Fasting is not abstinence. The current approaches to intermittent fasting are really intermittent abstinence. The idea is to abstain from food completely for 12 to 18 hours while still drinking liquids. That may not be possible for everyone. Some medications have to be taken in relation to food intake. Pre-diabetics and type 2 diabetics should still monitor blood sugar, especially if exercising during the fasting times. The current intermittent fasting approach is more about controlling when you eat than anything else, and that’s something you should do anyway.

I believe in fasting. That’s why I wrote Real-Life Detox—so you could do it right and gain the most benefit. The critical thing is to find a way to eat that you can sustain for the rest of your life, and that includes occasional fasts.

Eat less. Eat better. Move more. That’s always the goal.

Fasting and Immune Function

/in /by

Intermittent fasting is the latest health fad. When I say fad, I mean there are as many definitions of what it means as there are experts. In a recent edition of the journal Cell, three papers were published that provided some insight into the effects of three different types of intermittent fasting on three different systems involved in immune function. That’s our topic of the week. I’ll present each study and comment on the implications on Saturday.

In the first paper, researchers used juvenile mice to examine changes in immune function in sections of the intestine called Peyer’s patches (PP). These patches form an important part of the immune system by monitoring intestinal bacteria populations and preventing the growth of pathogenic bacteria in the intestines. The mice were fasted for 36 hours. Results were compared with normally fed mice that served as controls.

During fasting, immune cells were disrupted and thus compromised the typical immune response; specifically, B cells were sent to bone marrow. It’s difficult to say whether this is a protective mechanism or not. The B cells were returned to the PP during re-feeding. There were many more parts of the study, but the bottom line was that the immune system was compromised during fasting and remained impaired for a time after re-feeding.

We’ll take a look at the second study on Thursday.
