Choose Healthy Foods, Not Diet Foods

dieting adviceHow do you lose weight without counting calories?

Most adult Americans gain at least a pound or two each year. That may not sound like much on a yearly basis, but over a lifetime it is huge – if you’ll pardon the pun.

Because the health consequences of weight gain are so devastating, everyone has their favorite dietary advice for keeping those extra pounds away. For some it is diet plans – low fat, low carb, paleo, Mediterranean – you name it. For others, it is counting calories or avoiding sugars of all kinds. The list goes on.

But what if all those approaches were wrong? What if we could keep our weight under control solely based on the foods we eat? A recent study seems to suggest that we just might.

How Was The Study Designed?

A group of scientists from Tufts University and Harvard decided to look at how the food choices we make on a daily basis influence our weight gain or loss over time (Smith et al, AJCN 101: 1216-1224, 2015).

lose weight without counting caloriesMost studies of this kind look at what foods people are eating at the time of the study and compare that to how much they weigh. This group of scientists looked at changes that people made in their diets and correlated that with how much weight they gained or lost over time.

When you think of it, that’s the information most of us really want to know. We are less interested in why the foods we used to eat got us into trouble in the first place than we are in how the changes we make in our diet might influence future weight loss or gain.

This study combined the data from three very large, long term studies – the Nurses’ Health Study, the Nurses’ Health Study II, and the Health Professionals Follow-Up Study. Altogether that is a group of 120,784 men and women who were followed for 16-24 years. All three of these studies measured weight and evaluated dietary habits using food-frequency questionnaires every 4 years.

The scientists conducting the study measured changes in food choices and changes in weight over the duration of the studies. In analyzing the data, they looked at 3 variables: choices of protein foods, total carbohydrate, and the glycemic load (GL) of the carbohydrates.

Glycemic load is the effect on blood sugar of the carbohydrates in a food times the total amount of carbohydrate in that food. You can think of glycemic load as a measure of carbohydrate quality. Foods with low glycemic load have little effect on blood sugar. Foods with high glycemic load cause a major increase in blood sugar. You probably already know that is not a good thing.

You probably also have a pretty good idea of which foods have a high glycemic load. For example, white bread, pastries, muffins, pancakes, white rice, chocolates, candy bars, cookies, brownies, cakes, pies, and pretzels would all be examples of foods with a high glycemic load. Fruits, whole grain foods and starchy vegetables would be examples of foods with a moderate glycemic load. Vegetables and beans would be examples of foods that generally have a low glycemic load.

 

Lose Weight Without Counting Calories Means Foods  Are More Important Than Calories?

 

Now let’s get to the good stuff – the results of this study. When the authors analyzed the data they found that:

  • Most of the subjects did not exchange one protein food for another over the course of the study. They exchanged protein foods for carbohydrate-rich foods and vice versa.

This was a surprise. Since many experts have been recommending that people substitute chicken and fish for red meat, they had expected to see that kind of dietary shift when they analyzed the data. Apparently, people have not been listening to the experts!

  • When the subjects replaced a serving of carbohydrate-rich foods with a serving of red meats, processed meats, chicken with skin or most cheeses, they gained between 0.5 to 2.3 pounds per year. Within this category, the greatest weight gain was seen when hamburgers were substituted for carbohydrates, and the least weight gain was seen when cheese was substituted for carbohydrates. These are substitutions that pack on the pounds.
  • bad protein dietWhen the subjects replaced a serving of carbohydrate-rich foods with a serving of milk, peanuts or eggs, there was no net change in weight. These appear to be substitutions that are good for weight maintenance.
  • When the subjects replaced a serving of carbohydrate-rich foods with a serving of yoghurt, peanut butter, beans, walnuts, other nuts, chicken without skin, low-fat cheese or seafood, they lost between 0.5 and 1.5 pounds/year. These appear to be substitutions that are good for weight loss.
  • When they focused on carbohydrate-rich foods, replacing one serving of high glycemic load foods with low glycemic load foods was associated with one pound of weight loss per year. Simply put, if you switch from cookies, pastries and candies to fruits and vegetables, you are likely to lose weight. No surprise here.  This would seem to be a method to lose weight without counting calories.

The study really got interesting when they looked at the effect of adding different proteins in the context of the carbohydrate-rich foods that the subjects were eating. For example,

  • When the subjects added a serving of red meat to a diet containing carbohydrate foods with a high glycemic load, they gained an average of 2.5 pounds per year. When they added that same serving of red meat to a diet containing carbohydrate foods with a low glycemic load, they gained only around 1.5 pounds per year.

Simply put, that means eating a hamburger on a white flour bun with fries is going to pack on more pounds than a hamburger patty with brown rice and a green salad.

  • The effect of glycemic load was particularly interesting when you looked at the protein foods that were good for weight maintenance overall. For example, adding a serving of eggs to a high glycemic load diet resulted in a 0.6 pound/year weight gain, while adding that same serving of eggs to a low glycemic load diet resulted in a 1.75 pound/year weight loss. The results were similar for cheeses.
  • Finally, glycemic load also influenced the effectiveness of protein foods associated with weight loss. For example, addition of a serving of beans to a high glycemic load diet resulted in 0.5 pound/year weight loss, but adding a serving of beans to a low glycemic load diet resulted in a 1.5 pound/year weight loss.

New Insights From This Study

This study broke new ground in several areas. For example,

  • good protein dietWe have heard over and over that substituting beans, chicken and fish for red meats is healthier. This is the first study I have heard of that says those same substitutions can prevent or reverse weight gain.
  • Many people advocate a high protein diet for weight control or weight loss, but many of them will tell you the type of protein doesn’t matter. This study suggests that the type of protein foods we eat are important in determining whether we lose or gain weight.
  • Everyone knows that switching from white grains, pastries and candy to whole grains, fruits and vegetables will help you lose weight, but this is the first study I’m aware of that suggests those same changes will influence whether the protein foods we eat lead to weight gain or weight loss.
  • Many people focus on fats and calories when trying to avoid weight gain. While this study is not really fat and calorie neutral (see below), it does suggest that if we focus on eating healthy foods, we don’t need to be counting every fat gram and every calorie.  In other words, you can lose weight without counting calories by eating healthy foods.
  • Finally, this study suggests that if we forget all of those crazy diets and focus on eating healthy foods, our weight will take care of itself. Not exactly a novel concept, but one worth repeating.

 

Can We Lose Weight Without Counting Calories?

 

The head author of this study stated in an interview “The idea that the human body is just a bucket for calories is too simplistic. It’s not just a matter of thinking about calories or fat. What’s the quality of the foods we are eating? And how do we define quality.” This has been picked up by the media with statements like “not all calories are created equal”.

The real message is not that fat content and calories don’t count. Nor is it that calories in some foods count more than the same calories in other foods. The take home lesson from this study should be that we don’t have to focus on fat and calories. We don’t need to jump on the latest fad diet. If we focus on healthy foods, the fat and calories tend to take care of themselves.

But, even that message is a bit too simplistic. Choosing healthy foods is not all that there is for weight control. We also need consider:

  • Portion sizes. Half a chicken could easily add more calories than a small hamburger.
  • How the food is cooked. Fish cooked in a cream sauce may not be any better for weight control than a slab of red meat.
  • Exercise. We need to maintain muscle mass to keep metabolic rate high.

 

The Bottom Line

 

  • A recent study has broken new ground and provided some new insights into how to prevent those extra pounds from sneaking up on us over time. This study evaluated how some simple changes we could make in the foods we eat can influence whether we gain or lose weight.
  • One part of the study looked at the effects of replacing a serving of carbohydrate rich foods with a serving of protein rich foods. If that protein rich food were a hamburger, we could expect to gain about 2.3 pounds/year. If that protein rich food were seafood, we could expect to lose about 1.5 pounds/year. Other protein foods fall in between those extremes. The specifics are covered above.

This is a new insight. Many people advocate a high protein diet for weight control or weight loss, but many of them will tell you the type of protein doesn’t matter. This study suggests that the type of protein foods we eat are important in determining whether we lose or gain weight.

  • Another part of the study looked at the effect of different carbohydrate foods based on their glycemic load (the effect they have on blood sugar). Simply replacing 1 serving of high glycemic load foods (refined grain foods, cookies, cakes, candy) with low glycemic load foods (whole grains, fruits and vegetables) was associated with a one pound/year weight loss. This should surprise no one.
  • Finally, one part of the study looked at the influence of glycemic load on the effect that various proteins have on weight gain or loss. For example, adding a serving of eggs to a high glycemic load diet resulted in a 0.6 pound/year weight gain, while adding that same serving of eggs to a low glycemic load diet resulted in a 1.75 pound/year weight loss. Other examples are given above.

This is also a new insight. Everyone knows that switching from white grains, pastries and candy to whole grains, fruits and vegetables will help you lose weight, but this is the first study I’m aware of that suggests those same changes will influence whether the protein foods we eat lead to weight gain or weight loss.

  • Some in the media have interpreted this study as saying that fat and calories don’t count. However, this study was not designed to be fat and calorie neutral. The real take home message from this study is that we may not need to focus so much on fat and calories. When we focus on eating healthy foods the fat and calories tend to take care of themselves.
  • Even that message is a bit too simplistic. It is not enough to just focus on healthy foods. We need to consider things like portion size, how the food is prepared, and our exercise habits among other things.
  • I would be the first to acknowledge that many people need strict guidelines and a well-designed diet program to lose the extra pounds that have built up over the years. However, to keep the weight off they simply need to embrace a lifestyle that includes healthy food choices and regular exercise.  You can lose weight without counting calories.

    Very insightful! Thank you for breaking down, interpretations, and sharing the results of this study. So many diets, “lifestyle programs”, and even the smart phone nutrition tracking apps focus on caloric intake and not the quality and types of calories. This is another reminder to be mindful of what we eat! Thank you again, and also, thank you for your newsletter!

Omega-3 Benefits: Lower High Blood Pressure

Posted July 16, 2019 by Dr. Steve Chaney

What Does the FDA Say About Omega-3 Benefit Claims?

Author: Dr. Stephen Chaney

 

 

Among omega-3 benefits is lower high blood pressure.  That claim can be made according to the FDA. 

lower high blood pressureHeart Disease is still the number 1 cause of death in this country. And, while deaths from heart disease have been declining in recent years, deaths due to high blood pressure have been increasing.  That is concerning because:

High blood pressure is a killer! It can kill you by causing heart attacks, strokes, congestive heart failure, kidney failure and much more.

High blood pressure is a serial killer. It doesn’t just kill a few people. It kills lots of people. The American Heart Association estimates that high blood pressure directly or indirectly caused 410,000 deaths in 2014. That is almost 1 person every second and represents a 41% increase from 2000. It’s because high blood pressure is not a rare disease.

  • 32% of Americans have high blood pressure, also called hypertension, (defined as a systolic blood pressure of 140 mm Hg or more or a diastolic blood pressure of 90 mm Hg or more).
  • Another 33% of Americans have prehypertension (systolic blood pressure of 120-139 mm Hg or diastolic blood pressure of 80-89 mm Hg).

That’s over 65% of Americans with abnormal blood pressure!

High blood pressure is a silent killer. That’s because it is a very insidious disease that sneaks up on you when you least expect it. Systolic blood pressure increases 0.6 mm Hg/year for most adults over 50. By age 75 or above 76-80% of American adults will have high blood pressure.  Even worse, many people with high blood pressure have no symptoms, so they don’t even know that their blood pressure is elevated. For them the first symptom of high blood pressure is often sudden death.

Blood pressure medications can harm your quality of life. Blood pressure medications save lives. However, like most drugs, blood pressure medications have a plethora of side effects – including weakness, dizziness, fainting, shortness of breath, chest pain, nausea, diarrhea or constipation, heartburn, depression, heart palpitations, and even memory loss. The many side effects associated with blood pressure medications lead to poor compliance, which is probably why only 46% of patients with high blood pressure are adequately controlled.

You do have natural options. By now you are probably wondering whether there are natural approaches for controlling your blood pressure that are both effective and lack side effects. The answer is a resounding YES! I’ll outline a holistic natural approach for keeping your blood pressure under control in a minute but let me start with the FDAs recent approval of what they call “qualified claims” that omega-3s lower blood pressure.

 

What Does the FDA Say About Omega-3 Benefits?

omega-3 benefitsIn my book “Slaying The Supplement Myths” I talk about the “dark side” of the supplement industry. There are far too many companies who try to dupe the public by making outrageous and unsubstantiated claims about their products.

Only the FDA stands between us and those unscrupulous companies, and they take their role very seriously. That is why it is big news whenever the FDA allows companies to make health claims about their products.

Even then, the FDA is very cautious. They allow what they call “qualified” health claims. Basically, that means they are saying there is enough evidence that the health claim is probably true, but not enough evidence to say it is proven.

Of course, if you understand the scientific method, you realize there will always be some studies on both sides of every issue. That is why the only health claims the FDA allows are qualified health claims.

With that background in mind, let’s look at the qualified health claims the FDA allows for omega-3 benefits.

  • Since 2004 the FDA has allowed the qualified claim “Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.”
  • A few weeks ago, they added five qualified health claims about omega-3s and blood pressure. The 5 claims are very similar, so I will only list two below for the sake of brevity.
  • “Consuming EPA and DHA combined may reduce blood pressure and reduce the risk of hypertension, a risk factor for CHD (coronary heart disease).”
  • Consuming EPA and DHA combined may reduce the risk of CHD (coronary heart disease) by lowering blood pressure.
  • Of course, they add the usual wording about the evidence being inconsistent and inconclusive.

 

Omega-3 Benefits?

measure omega-3 benefits levelWe’ve known for some time that omega-3 fatty acids help lower blood pressure, but two recent studies were instrumental in convincing the FDA to allow these qualified health claims. These studies have highlighted just how strong the effect of omega-3s on lowering blood pressure is.

The first study was a meta-analysis of 70 randomized, placebo-controlled clinical trials of long chain omega-3 (EPA + DHA) supplementation and blood pressure (Miller et al, American Journal of Hypertension, 27: 885-896, 2014 ).

This study showed:

  • In the group with normal blood pressure at the beginning of the study EPA + DHA supplementation decreased systolic blood pressure by 1.25 mm Hg.
  • Given that systolic blood pressure rises an average of 0.6 mm Hg/year in adults over 50, the authors estimated that omega-3 supplementation alone would delay the onset of age-related high blood pressure by 2 years.
  • In the group with elevated blood pressure not taking medication at the beginning of the study, EPA + DHA supplementation decreased systolic blood pressure by an impressive 4.51 mm Hg and diastolic blood pressure by 3.05 mm Hg.
  • The authors noted that this decrease in systolic blood pressure could “prevent an individual from requiring medication [with all its side effects] to control their hypertension” or decrease the amount of medication required.

However, the doses of omega-3s used in these studies ranged from 1 to over 4 grams/day (mean dose = 3.8 grams/day). That sparked a second study (Minihane et al, Journal of Nutrition, 146: 516-523, 2016) to see whether lower levels of omega-3s might be equally effective. This study was an 8-week double-blind, placebo-controlled study comparing the effects of 0.7 or 1.8 grams of EPA + DHA per day (versus an 8:2 ratio of palm and soybean oil as a placebo) on blood pressure.

This study showed:

  • In the group with normal blood pressure at the beginning of the study, EPA + DHA supplementation caused no significant decrease in blood pressure. This could be due to the smaller number of subjects or the lower doses of EPA + DHA used in this study.
  • In the group with elevated blood pressure not taking medication at the beginning of the study, EPA + DHA supplementation decreased systolic blood pressure by 5 mm Hg and, the effect was essentially identical at 0.7 grams/day and 1.8 grams/day.
  • The authors concluded “Our data suggest that increased EPA + DHA intakes of only 0.7 grams/day may be an effective strategy for blood pressure control.”

 

A Holistic Approach to Lower High Blood Pressure

holistic approach to lower high blood pressureThe FDA’s allowed claims about omega-3s are good news indeed, but that’s not the only natural approach that lowers blood pressure. You have lots of other arrows in your quiver. For example:

  • The DASH diet (A diet that has lots of fresh fruits and vegetables; includes whole grains, low fat dairy, poultry, fish, beans, nuts and oils; and is low in sugar and red meats) reduces systolic blood pressure by 5-6 mm Hg. [Low fat, low carb and Mediterranean diets also lower blood pressure, but not by as much as the DASH diet].
  • Reducing sodium by about 1,150 mg/day reduces systolic blood pressure by 3-4 mm Hg.
  • Reducing excess weight by 5% reduces systolic blood pressure by 3 points.
  • Doing at least 40 minutes of aerobic exercise 3-4 times/week reduces systolic blood pressure by 2-5 mm Hg.
  • Nitrates, whether derived from fresh fruits and vegetables or from supplements probably also reduce blood pressure, but we don’t yet know by how much.

If you’ve been keeping track, you’ve probably figured out that a holistic lifestyle that included at least 0.7 grams/day of long chain omega-3s (EPA + DHA) plus the other omega-3 benefits in the list above could reduce your systolic blood pressure by a whopping 18-22 mm Hg.  What

That’s significant because, the CDC estimates that reducing high systolic blood pressure by only 12-13 mm Hg could reduce your risk of:

  • Stroke by 37%.
  • Coronary heart disease by 21%.
  • Death from cardiovascular disease by 25%.
  • Death from all causes by 13%.

 

A Word of Caution

While holistic approaches have the potential to keep your blood pressure under control without the side effects of medications, it is important not to blindly rely on holistic approaches alone. There are also genetic and environmental risk factors involved in determining blood pressure. You could be doing everything right and still have high blood pressure. Plus, you need to remember that high blood pressure is a silent killer that often doesn’t have any detectable symptoms prior to that first heart attack or stroke.

My recommendations are:

  • Monitor your blood pressure on a regular basis.
  • If your blood pressure starts to become elevated, consult with your doctor about starting with natural approaches to bring your blood pressure back under control. Doctors are fully aware of the side effects of blood pressure medications, and most doctors are happy to encourage you to try natural approaches first.
  • Continue to monitor blood pressure as directed by your doctor. If natural approaches are insufficient to bring your blood pressure under control, they will prescribe the lowest dose of blood pressure medication possible to get your blood pressure where it needs to be.
  • Don’t stop making holistic lifestyle choices to reduce blood pressure just because you are on medication. The more you do to keep your blood pressure under control with a healthy diet and lifestyle, the less medication your doctor will need to use (That means fewer side effects).

 

The Bottom Line

Heart Disease is still the number 1 cause of death in this country. And, while deaths from heart disease have been declining in recent years, deaths due to high blood pressure have been increasing. That is why anything we can do lower blood pressure naturally is important. What does the FDA say about omega-3s and blood pressure?

  • Since 2004 the FDA has allowed the qualified claim “Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.”
  • A few weeks ago, they added qualified health claims about omega-3s and blood pressure. For example, they now allow the following claims.
  • “Consuming EPA and DHA combined may reduce blood pressure and reduce the risk of hypertension, a risk factor for CHD (coronary heart disease).”
  • Consuming EPA and DHA combined may reduce the risk of CHD (coronary heart disease) by lowering blood pressure.
