Wish I Knew At 20

Author: Dr. Stephen Chaney

how to live a healthy lifestyleI wish I knew how to live a healthy lifestyle when I was 20.  But, I was a typical 20-year-old American. I ate lots of junk food. I thought an occasional tennis game was all the exercise I needed. I never really thought about what I was doing. I just did what all my friends did. If I hadn’t changed what I was doing, I might have had a short, unhealthy life.

Of course, I did change, and those changes made all the difference. Now I’m in my 70s, and I’m in perfect health. I have no diseases. Even the allergies I had when I was younger have gone away as I improved my diet and lifestyle. I am on no medications. I have the blood pressure of a 16-year-old.

I call this article “How to Live a Healthy Lifestyle:  Wish I Knew At 20”, but this article isn’t about me. I wrote this article for all the other 20-year-olds who know as little about nutrition and health as I did at 20. I also wrote this article for all those people who haven’t changed – those people with the same diet and lifestyle they had at 20. It’s never too late to change and begin to live a healthy lifestyle.

 

How to Live a Healthy Lifestyle:  What I Wish I Knew At 20

 

Here are 15 tips I would pass along to all the 20-year-olds, even those 20-year-olds in older bodies:

#1: You Are In Charge: You have a brain. You have free will. You don’t have to do what everyone else is doing. It is time to start thinking about what your health and your life will be like if you don’t change. More importantly, it is time to start thinking about what your health and your life could be like if you do make positive changes.

#2: It Matters: I can’t emphasize strongly enough how important it is to make positive changes in your diet, your exercise, and your overall lifestyle. We know all the major killer diseases (heart disease, cancer, diabetes, hypertension, etc) are affected by diet and lifestyle. However, it is much more than avoiding disease. As you age, your quality of life is dramatically affected by how much you have moved and what you have put in your mouth over your lifetime.

If you have any question about how important healthy eating can be, take time to view documentary movies like “Forks Over Knives” or “Eating You Alive.” I’m not necessarily advocating that extreme a diet, but these films will get you thinking.

fad diets#3: Avoid the Fads: Once you have decided to adopt a healthier lifestyle, the hardest part is deciding which changes you should make. You will need to practice a lot of due diligence. There is a lot of hype and misinformation out there. There is a new fad every week. First, it’s low fat. Then it’s low carb. Then it’s no bananas before noon on Thursdays (I’m joking here, but you get the point. Some of the diets are just plain weird).

Most of those diet recommendations sound plausible. They all have their advocates who are only too happy to offer their testimonials. My advice: If it sounds too good to be true, avoid it. If they tell you the medical profession is trying to keep their diet a secret, avoid it. The consensus advice of the medical and nutrition communities may seem boring, but it is generally based on dozens of clinical studies. It is much more likely to be true than advice from your friends, your trainer, or that blogger who values controversy more than accuracy.

#4: We Are All Different: Health recommendations are usually based on dozens of clinical studies. But, here is the secret that only scientists know. Clinical studies report averages, but none of us are average. Let me give you an example. Let’s say you wanted to do a clinical study to evaluate whether a low-carb diet helps people lose weight. You might enroll several hundred people in your study. If you put them all on an identical low-carb diet for 8 weeks, some of them would lose weight. Others would gain weight. At the end of the 8 weeks, you would average all weight changes together and report the average weight loss.

For the sake of argument, let’s say the average weight loss was 6.4 pounds. That’s fine except that not a single person in the study lost exactly 6.4 pounds, and some may have even gained weight. The bottom line is that your results may be different from conventional wisdom. Your results may be different from your friend’s. You will need to find out what works best for you.

#5: You Don’t Have To Change All At Once: Some people have an iron will and can make drastic changes overnight. Most of us aren’t like that. If we try to change too many things at once, we become overwhelmed. We become discouraged. Sometimes we quit. Think of this as a marathon, not a sprint. Make “Change One” your slogan. Change one thing each week until you are where you want to be. One week it may be replacing sugary desserts with fruits. Another week it may be adding a green vegetable to your dinner plate. Over time, all those small changes will result in a totally different lifestyle.

processed foods#6: Your Tastes Will Change: The first time you choose a low sodium food, it will taste bland. Over time you will come to enjoy the subtle flavors of the food and will come to dislike added salt. The first time you switch from whole milk to low fat milk it will taste like water. Over time you will learn to appreciate low fat milk, and whole milk will taste greasy. I could give lots more examples, but you get the point.

#7: Processed Foods, Sweets, and Sodas Will Kill You: I’m being dramatic here, but they are bad for your health. They have no place as part of a healthy diet. Replace the processed foods and sweets with whole foods. Replace the sodas with water or herbal teas.

#8: It’s What You Do Every Day That Matters: Refined grains, pastries and sweets should be only an occasional indulgence. Fruits, vegetables, and whole grains should be the mainstay of your everyday diet. Eat a plant-based diet as much as possible.

#9: Protein Is Important, Especially As We Get Older: Low fat or vegetarian protein sources should be your first choice. Chicken (with the skin removed) and fish are the healthiest meats. Nuts, beans & seeds are excellent vegetarian protein sources, especially in combination. Think of red meats as no more than an occasional indulgence.

#10: Avoid The Center Of The Supermarket: This is my only shopping advice. In general, supermarkets are arranged with real foods around the edges and the processed foods in the middle.

organic foods#11: Choose Organic: Our planet has become so polluted that is has become impossible to completely avoid toxic chemicals in our environment. They are in our air, our water, our soil, and our homes. Our only defense is to be informed consumers and avoid them whenever possible. If the cost of organic produce is an issue for you, be selective. There is a Dirty Dozen  list of fruits and vegetables that are the ones most likely to be contaminated with pesticides and herbicides.

#12: Get Lots Of Exercise: Most experts recommend at least 30 minutes of moderate intensity exercise 5 times per week. More is even better. For best results choose a combination of aerobic and weight bearing exercise.

#13: Control Your Weight: We are in the midst of an obesity epidemic. The problem is that 80% of us are genetically predisposed to become obese if we eat a typical American diet and follow a typical American lifestyle. The solution isn’t the fad diet du jour. The solution is to change our diet and our lifestyle. For most of us, the changes I have outlined above will allow you to gradually attain & maintain your ideal weight.

#14: Supplementation Plays A Role: Supplementation is not a magic bullet, but it is an important component of a holistic wellness program. Some of us need supplementation to fill in nutritional gaps in our diet. Some of us need supplementation because of increased needs, either because of disease or genetics. Some of us choose supplementation to achieve optimal health.

#15: Enjoy The Journey: If you think of a healthy lifestyle as depriving you of the things you enjoy, you will avoid it. Instead, think of it as an adventure. Have fun exploring new fruits and vegetables. Try cooking with herbs and spices. Seek out restaurants and recipes that turn healthy foods into a gourmet experience. Find exercises that you actually enjoy.  Now you know how to live a healthy lifestyle and for longer.

    I have seek advice to use a defense mechanism to Improve bad eating habits, weightloss, and health concerns. I decided to follow the pathway 15 tips and Avoid Fads and eliminate sweets. I am learning to eat dinner early before a walk during the evening hours. I am still “stuck” when making a decision whether I am a Vegetarian or Vegan food water.

      Dear Felicia,

      As long as you eliminate sodas, fast & convenience foods, refined carbs and sugar, it really doesn’t matter whether you choose Vegan or Vegetarian. Both are healthy.

A Low Carb Diet and Weight Loss

Posted January 15, 2019 by Dr. Steve Chaney

Do Low-Carb Diets Help Maintain Weight Loss?

Author: Dr. Stephen Chaney

 

low carb dietTraditional diets have been based on counting calories, but are all calories equal? Low-carb enthusiasts have long claimed that diets high in sugar and refined carbs cause obesity. Their hypothesis is based on the fact that high blood sugar levels cause a spike in insulin levels, and insulin promotes fat storage.

The problem is that there has been scant evidence to support that hypothesis. In fact, a recent meta-analysis of 32 published clinical studies (KD Hall and J Guo, Gastroenterology, 152: 1718-1727, 2017 ) concluded that low-fat diets resulted in a higher metabolic rate and greater fat loss than isocaloric low-carbohydrate diets.

However, low-carb enthusiasts persisted. They argued that the studies included in the meta-analysis were too short to adequately measure the metabolic effects of a low-carb diet. Recently, a study has been published in the British Medical Journal (CB Ebbeling et al, BMJ 2018, 363:k4583 ) that appears to vindicate their position.

Are low carb diets best for long term weight loss?

Low-carb enthusiasts claim the study conclusively shows that low-carb diets are best for losing weight and for keeping it off once you have lost it. They are saying that it is time to shift away from counting calories and from promoting low-fat diets and focus on low-carb diets instead if we wish to solve the obesity epidemic. In this article I will focus on three issues:

  • How good was the study?
  • What were its limitations?
  • Are the claims justified?

 

How Was The Study Designed?

low carb diet studyThe investigators started with 234 overweight adults (30% male, 78% white, average age 40, BMI 32) recruited from the campus of Framingham State University in Massachusetts. All participants were put on a diet that restricted calories to 60% of estimated needs for 10 weeks. The diet consisted of 45% of calories from carbohydrate, 30% from fat, and 25% from protein. [So much for the claim that the study showed low-carb diets were more effective for weight loss. The diet used for the weight loss portion of the diet was not low-carb.]

During the initial phase of the study 161 of the participants achieved 10% weight loss. These participants were randomly divided into 3 groups for the weight maintenance phase of the study.

  • The diet composition of the high-carb group was 60% carbohydrate, 20% fat, and 20% protein.
  • The diet composition of the moderate-carb group was 40% carbohydrate, 40% fat, and 20% protein.
  • The diet composition of the low-carb group was 20% carbohydrate, 60% fat, and 20% protein.

Other important characteristics of the study were:

  • The weight maintenance portion of the study lasted 5 months – much longer than any previous study.
  • All meals were designed by dietitians and prepared by a commercial food service. The meals were either served in a cafeteria or packaged to be taken home by the participants.
  • The caloric content of the meals was individually adjusted on a weekly basis so that weight was kept within a ± 4-pound range during the 5-month maintenance phase.
  • Sugar, saturated fat, and sodium were limited and kept relatively constant among the 3 diets.

120 participants made it through the 5-month maintenance phase.

 

Do Low-Carb Diets Help Maintain Weight Loss?

low carb diet maintain weight lossThe results were striking:

  • The low-carb group burned an additional 278 calories/day compared to the high-carb group and 131 calories/day more than the moderate-carbohydrate group.
  • These differences were even higher for those individuals with higher insulin secretion at the beginning of the maintenance phase of the study.
  • These differences lead the authors to hypothesize that low-carb diets might be more effective for weight maintenance than other diets.

 

What Are The Pros And Cons Of This Study?

low carb diet pros and consThis was a very well-done study. In fact, it is the most ambitious and well-controlled study of its kind. However, like any other clinical study, it has its limitations. It also needs to be repeated.

The pros of the study are obvious. It was a long study and the dietary intake of the participants was tightly controlled.

As for cons, here are the three limitations of the study listed by the authors:

#1: Potential Measurement Error: This section of the paper was a highly technical consideration of the method used to measure energy expenditure. Suffice it to say that the method they used to measure calories burned per day may overestimate calories burned in the low-carb group. That, of course, would invalidate the major findings of the study. It is unlikely, but it is why the study needs to be repeated using a different measure of energy expenditure.

#2: Compliance: Although the participants were provided with all their meals, there was no way of being sure they ate them. There was also no way of knowing whether they may have eaten other foods in addition to the food they were provided. Again, this is unlikely, but cannot be eliminated from consideration.

#3: Generalizability: This is simply an acknowledgement that the greatest strength of this study is also its greatest weakness. The authors acknowledged that their study was conducted in such a tightly controlled manner it is difficult to translate their findings to the real world. For example:

  • Sugar and saturated fat were restricted and were at very similar levels in all 3 diets. In the real world, people consuming a high-carb diet are likely to consume more sugar than people in the other diet groups. Similarly, people consuming the low-carb diet are likely to consume more saturated fat than people in the other diet groups.
  • Weight was kept constant in the weight maintenance phase by constantly adjusting caloric intake. Unfortunately, this seldom happens in the real world. Most people gain weight once they go off their diet – and this is just as true with low-carb diets as with other diets.
  • The participants had access to dietitian-designed prepared meals 3 times a day for 5 months. This almost never happens in the real world. The authors said “…these results [their data] must be reconciled with the long-term weight loss trials relying on nutrition education and behavioral counseling that find only a small advantage for low carbohydrate compared with low fat diets according to several recent meta-analyses.” [I would add that in the real world, people do not even have access to nutritional education and behavioral modification.]

 

low carb diet and youWhat Does This Study Mean For You?

  • This study shows that under very tightly controlled conditions (dietitian-prepared meals, sugar and saturated fat limited to healthy levels, calories continually adjusted so that weight remains constant) a low-carb diet burns more calories per day than a moderate-carb or high-carb diet. These findings show that it is theoretically possible to increase your metabolic weight and successfully maintain a healthy weight on a low-carb diet. These are the headlines you probably saw. However, a careful reading of the study provides a much more nuanced viewpoint. For example, the fact that the study conditions were so tightly controlled makes it difficult to translate these findings to the real world.
  • In fact, the authors of the study acknowledged that multiple clinical studies show this almost never happens in the real world. These studies show that most people regain the weight they have lost on low-carb diets. More importantly, the rate of weight regain is virtually identical on low-carb and low-fat diets. Consequently, the authors of the current study concluded “…translation [of their results to the real world] requires exploration in future mechanistic oriented research.” Simply put, the authors are saying that more research is needed to provide a mechanistic explanation for this discrepancy before one can make recommendations that are relevant to weight loss and weight maintenance in the real world.
  • The authors also discussed the results of their study in light of a recent, well-designed 12-month study (CD Gardener et al, JAMA, 319: 667-669, 2018 ) that showed no difference in weight change between a healthy low-fat versus a healthy low-carbohydrate diet. That study also reported that the results were unaffected by insulin secretion at baseline. The authors of the current study noted that “…[in the previous study] participants were instructed to minimize or eliminate refined grains and added sugars and maximize intake of vegetables. Probably for this reason, the reported glycemic load [effect of the diet on blood sugar levels] of the low-fat diet was very low…and similar to [the low-carb diet].” In short, the authors of the current study were acknowledging that diets which focus on healthy, plant-based carbohydrates and eliminate sugar, refined grains, and processed foods may be as effective as low-carb diets for helping maintain a healthy weight.
  • This would also be consistent with previous studies showing that primarily plant-based, low-carb diets are more effective at maintaining a healthy weight and better health outcomes long-term than the typical American version of the low-fat diet, which is high in sugar and refined grains. In contrast, meat-based, low-carb diets are no more effective than the American version of the low-fat diet at preventing weight gain and poor health outcomes. I have covered these studies in detail in my book “Slaying The Food Myths.”

Consequently, the lead author of the most recent study has said: “The findings [of this study] do not impugn whole fruits, beans and other unprocessed carbohydrates. Rather, the study suggests that reducing foods with added sugar, flour, and other refined carbohydrates could help people maintain weight loss….” This is something we all can agree on, but strangely this is not reflected in the headlines you may have seen in the media.

The Bottom Line

 

  • A recent study compared the calories burned per day on a low-carb, moderate-carb, and high-carb diet. The study concluded that the low-carb diet burned significantly more calories per day than the other two diets and might be suitable for long-term weight control. If confirmed by subsequent studies, this would be the first real evidence that low-carb diets are superior for maintaining a healthy weight.
  • However, the study has some major limitations. For example, it used a methodology that may overestimate the benefits of a low-carb diet, and it was performed under tightly controlled conditions that can never be duplicated in the real world. As acknowledged by the authors, this study is also contradicted by multiple previous studies. Further studies will be required to confirm the results of this study and show how it can be applied in the real world.
  • In addition, the kind of carbohydrate in the diet is every bit as important as the amount of carbohydrate. The authors acknowledge that the differences seen in their study apply mainly to carbohydrates from sugar, refined grains, and processed foods. They advocate diets with low glycemic load (small effects on blood sugar and insulin levels) and acknowledge this can also be achieved by incorporating low-glycemic load, plant-based carbohydrates into your diet. This is something we all can agree on, but strangely this is not reflected in the headlines you may have seen in the media.
  • Finally, clinical studies report averages, but none of us are average. When you examine the data from the current study, it is evident that some participants burned more calories per hour on the high-carb diet than other participants did on the low carb diet. That reinforces the observation that some people lose weight more effectively on low-carb diets while others lose weight more effectively on low-fat diets. If you are someone who does better on a low-carb diet, the best available evidence suggests you will have better long-term health outcomes on a primarily plant-based, low-carb diet such as the low-carb version of the Mediterranean diet.
