Three Exercise Programs You Can Do Anywhere!

Turkey, pumpkin pie, holiday parties, alcohol, sweet treats, 12-hours of college bowl games, and non-stop travel to visit family and friends—the inevitable holiday weight gain. Too many calories and no time or place to work out. When the holiday season comes, people want healthy eating options. I get it, diet is important, but I am not going to be giving out recipes here. If you want a stellar gluten-free mashed potato recipe or a simple salt-free, sugar-free, protein-free honey glazed ham recipe, go elsewhere. I am going to help you get moving. Movement equals calorie burn, and the goal of this blog is to provide you with three exercise programs that you can do anywhere without equipment. The programs are designed as circuit programs, which have been shown to be most effective at burning calories.

Weight Loss: Burn the Treadmill

You’re being duped folks! Long duration cardio training does not make you lose more fat and weight. If I had a dollar for each time I heard the phrase, “… but I need to do cardio so I can burn fat and lose weight…” I’d be rich. This statement couldn’t be further from the truth. I understand where the confusion comes. It’s really not your fault. You’re being hoodwinked by health and wellness companies who put on this persona that they are health experts. They are not. These are simply business savvy folks who misinterpret science and pass garbage on to you. Let me explain.

First, the respiratory exchange ratio (RER) says that fat is metabolized greatest when the body is at rest. This is true. However, the aforementioned wellness companies misinterpret this and say that the closer the exercise level is to low intensity, the greater the fat loss. Thus, they try to give you these easy to follow fat burning weight loss guidelines. Have you seen those ridiculous diagrams on cardio machines that say 55%-65% of max heart rate is the “Fat Burning Zone” (see image). We also have trusted magazines like Women’s Health and Fitness that give you a Fat Burning Zone calculator. If you plug data in to the Women’s Health and Fitness calculator you will see that they also recommend you work at approximately 60% max heart rate.  We trust this information and are led to believe that lower intensity, longer duration activity equals weight loss. This is untrue. Continue reading

Postpartum Weight Loss

€~

One of the most common inquires I get is from new moms looking to lose that postpartum belly. How is it possible that celebrities like Heidi Klum can drop 30-40 pounds in just 4 months?  Anna Paquin goes from twins to 6-pack abs in 5 months. For new moms, that is frustrating, when you work so hard to lose stubborn body weight. What do they do that you don’t? Trust me, there is no super-secret information or magic formula that only they are privy to. You have the same physiology and weight loss capabilities as Hollywood superstars.

Normal weight gain during pregnancy is 30-35 pounds. Roughly 10 pounds is lost immediately after birth – seven pounds for the baby, plus two-three for blood, amniotic fluid and other. Through the first week your body will flush another 5 pounds of reserved water weight.  Optimal weight loss should be 1-2 pounds per week. If you do the math, you will find that Anna Paquin and Heidi Klum lost about 2 pounds per week.  Suddenly, Heidi and Anna’s weight loss isn’t so dramatic, does it? A loss of 1-2 pounds per week is easily attainable if you are diet compliant and dedicated to exercise. Continue reading

ENOUGH! Weight Loss is NOT Rocket Science

This blog should more appropriately be titled my rant of the month:

How many diet fads come out every year? Atkins, Zone, Paleo, Low-fat, South Beach, Intermittent Fasting are some of the most popular, but there are hundreds more pumped out every year. Why do we have new diets every year? Because there is not, nor will there ever be, a diet that can guarantee weight loss. Researchers keep making weight loss a scientific endeavor. The researchers then publish the findings, sell books, get rich and then the diet fades. Enough already, weight loss is not rocket science. It’s simple: balance energy by eating better and getting off of your ass. To prove my point let’s compare the data on a controversial issue: high-protein, low-carbohydrate vs. low-fat diets.

In 2002 a study done from Duke University researchers comparing a high protein low carb diet versus a traditional low-fat diet. The results of this study became much publicized and launched the Atkins Diet revolution. It hit mainstream media with a left and right hook. The diet quickly became one of the best-selling diet plans of all-time. But pundits refuted the data stating unreliable and invalid data. Today, there is valid points of discussion made by both sides.

Like most research and controversial issue, the data is for and against the high-protein diet is equivocal. In 2003, the New England Journal of Medicine published two studies which compared a low-carbohydrate diet to a calorie-restricted, low-fat diet in obese adults (1, 2). After six months both studies showed that low-carbohydrate subjects lost more weight and had significant reductions in markers for cardiovascular disease. This includes decreased triglyceride levels. However, after one year of performing the diets, weight loss and triglyceride levels were similar. But like many diets, compliance is an issue and in both studies there was a high dropout rate – thus data is unreliable.

As I had mentioned, pundits refuted the data. Most stated, that carbohydrate restriction was not the reason for weight loss, rather it was attributed to calorie deficit. This is similar to the systematic literature review done by Bravata, et al concluded that participant weight loss on low-carbohydrate diets was a result of caloric restriction, but carbohydrate restriction (3).

So Atkins, does yield weight loss, but why? Can I really eat a bacon cheeseburger (with no bun) and lose weight? Physiologically, carbohydrates are the body’s primary fuel source. When we eat carbohydrates the food is broken down and stored in skeletal muscle tissue and liver as glycogen, an easy to use energy source. When we eliminate carbohydrates from our diet we also eliminate glycogen stores.  Without glycogen, our body must use fat as energy. Subsequently, our body enters a state of ketosis – a state where ketone bodies are produced when fatty acids are broken down for energy. The loss of glycogen stores – and associated water loss – coupled with increased fat metabolism creates weight loss. In addition, the breakdown of fat is much more difficult than breaking down glycogen. Thus, our body must expend more energy to convert fat to energy (4) – burn energy to create energy.

But there are risks to eating a high-protein, low carbohydrate diet, right? The answer is yes and no. Many have stated a high-protein diet causes kidney and liver issues as well as abnormal insulin metabolism. Levine et al performed a research review  on low-carbohydrate diets and found little data to say a high-protein, low-carbohydrate diet causes health concerns (5). However, many studies have found that the diet does cause common side effects such as constipation, nausea, weakness, dehydration, and fatigue.

Is there a winning diet method? Simply put – the answer is no. While South Beach, the Zone, Atkins and others have all remained the most popular, there is not winner. If there were some magical remedy we would never again have new diet fads. After reviewing all of the data there is one constant: all weight loss is associated with negative energy balance. Meaning, you are burning more calories than you are consuming.

Remember Super-Size Me? The guy who ate McDonald’s everyday and gained weight. Well have you heard of Doug Logeais? He ate McDonald’s everyday for 30 days and lost weight! How, he exercised. He trained most days of the week at a high intensity – he burned more calories than he consumed.  Has anyone seen Michael Phelps’ diet? Big Mac, Pizza, soda, ice cream, 10,000 calories per day in food, but nobody says he has a weight problem. He is a long, lean and the greatest Olympic athlete of all time. Does he need to change his diet? Can you honestly say that he is doing something wrong? He is fit because his exercise off-sets calorie consumption.

My final opinion: regular physical activity combined with a well-balanced diet is paramount.  Weight maintenance requires permanent changes to eating habits and increased physical activity. The specific strategies for making those changes, and making them permanent, will vary from person to person. So, instead of a walking through the local book store of the best-selling diet book, save your money. Take a walk through your neighborhood. Instead of cheeseburger and fries – order a turkey burger and side salad. This is not rocket science – quit trying to make it more difficult than it is.

Weight Loss Challenges? Have You Tried Intermittent Fasting?

How many diets have you tried? How many times have you failed? The term ‘fad diet’ is a gross understatement, all diets are fads. I cannot think of a single diet that has been around for years, can you? Most diets are difficult to follow – bland, costly, and inconvenient – subsequently, there is a high rate of non-compliance to the diet strategy.   What if a diet asked you to eat a little healthier and take 1 day off per week? That doesn’t sound that hard does it?

The concept of Intermittent Fasting has been around for many years. In fact, our ancestors were forced to occasionally fast. Recently, I learned about intermittent fasting by John Berardi, Founder of Precision Nutrition System and leading nutritional scientist. I read his book and became hooked on the concept. In the simplest explanation, one day a week, you fast for an entire day (20-24 hours). For example, eat regular meals Tuesday through Sunday. On Sunday night eat dinner at your normal time (7 pm). Then don’t eat until Monday evening at dinner time.  During the fasting period, drink water and take a multivitamin if you want to. When you resume eating, don’t run to a fast-food chain and order 3 double cheeseburgers, an extra large fry, and a milkshake. Just, resume normal, healthy eating.

“I’ll Starve to death”, is the immediate response. No, you won’t. Our ancestors went 2-3 days without eating, they survived. Second, you will quickly learn that you are less hungry at hour 20 than you were at hour 4. We have hormones in our body, which trigger the feeling of hunger, but once you get past the initial hunger phase, the hormone response is suppressed and hunger subsides.

A single day of fasting creates a negative energy balance (expending more calories than consuming) of 2000-3000 calories. Consider that one-pound of fat is equivalent to 3,500 calories, you can see how easy it is to reach the negative energy balance and weight loss. There are physiological benefits that go beyond negative energy balance and weight loss:

  • Improved blood lipid profile (decreased LDL, increased HDL)
  • Reduced blood pressure
  • Reduction of inflammatory markers such as C-Reactive Protein
  • Improved fat metabolism
  • Increased insulin sensitivity (blood sugar control)
  • Enhanced Autophagocytosis (cellular repair)

It should be noted, that the above is based on fasting for 18-24 hours. Fasting for longer periods or more frequently does not enhance or expedite these results. Improving health is never quick and easy. Exercise or diet alone will not create life lasting health improvements.  The improvements noted above are a result of intermittent fasting, combined with overall healthier eating and regular exercise. Ultimate health and wellness come from a combination of diet and exercise.

Two months ago I started a paleolithic diet after doing my own independent research on diet and inflammation (I blogged about it). The data was so overwhelming I had to try it for 30 days. I loved it. Now I am combining a less strict version of Paleo with John Berardi’s intermittent fasting program. After 45 days, I lost 15 pounds and feel fantastic.  Easiest diet I have tried.
