Weight Loss – Down to Exercise or Diet?

You have probably heard Michelle Obama and many others telling overweight people that they can drop their extra pounds by picking up their running shoes. But is this really the answer to the increasing epidemic of obesity spreading around the world?

An Instructor from T Colin Campbell’s Centre for Nutrition Studies considers that her personal experience suggests that this is simply NOT the answer…

Healthy Weight Loss = 80% Nutrition + 20% Exercise

 

 appeared in the 1998 edition of Shape magazine as one of their “Success Stories” for weight loss.

She was engaged in “an excruciating exercise program of power walking/jogging 35-40 miles per week, plus an additional 20 miles on the bike.” Of course she lost weight, but as the years passed she found that the unwelcome pounds came creeping back.

She read an article that, at the time, seemed to explain why this might be happening: “…as we age, our metabolism slows down due to natural muscle mass decreases, so we need to increase our calorie burning exercise. If we don’t, we gain 10 lbs every few years, even though we are still exercising.”

Discouraged by the thought of having to continually ramp up the extreme exercise as each year passed, she found that her health started to decline – “…high cholesterol, high blood pressure, swollen and painful joints, and hormonal issues. I was only in my forties, and my lack of health had become a source of great stress. I couldn’t imagine what I would be like in my 60’s. My joints already hurt so much!”

Eventually, she came across the landmark documentary film Forks Over Knives. Things changed from then on. And she was not alone. This very film revolutionised my life and the lives of many people I come across daily.

Terri, like many, many others, learned that optimal health was not about exercising more. Rather, it was about eating the right foods. “Not chicken and fish like I had thought, but whole grains, legumes, vegetables, and fruits!”

  • Leanest cut of beef ~28% calories from fat
  • Skinless chicken breast ~ 24% from fat
  • Tuna ~21% from fat
  • Salmon ~ 40% from fat
  • Eggs ~70% from fat!

Nutrition is Key

Even though she continued to consider that exercise and stress management are important “…the real key—80% of the equation—is nutrition – in particular, eating plants.

Now, her main exercise is walking the dog daily for around 30-45 minutes with some gentle yoga four days a week – without the dog, I guess!

She says that her cholesterol levels have dropped and she no longer suffers from inflammation or pain.

While exercise and stress management are “…very important pieces to the health puzzle; it’s not whole without them. But, nutrition is the biggest piece of the picture. “You can’t outrun your fork.” “


Some edited thoughts (1.) from Dr. Greger

The food industries like to blame inactivity as the prime cause of obesity, not the promotion and consumption of their calorie-rich products. (2.) On the contrary, however, research suggests that the level of physical activity may have actually increased in the United States over the past few decades. (3.) We know that obesity is rising even in areas where people are exercising more. (4.) This is likely explained by the fact that eating activity levels are outstripping physical activity levels. (5.)…Researchers who accept grants from the Coca-Cola Company (6.) call physical inactivity “the biggest public health problem of the 21st century.” (7.) Actually, physical inactivity ranks down at number five in terms of risk factors for death in the United States and number six in terms of risk factors for disability. (8.) And inactivity barely makes the top ten globally. (9.)

diet is by far our greatest killer, followed by smoking. (10.)

Of course, that doesn’t mean you should sit on the couch all day…. in addition to helping you enjoy a healthy body weight, exercise can also ward off and possibly reverse mild cognitive decline, boost your immune system, prevent and treat high blood pressure, and improve your mood and quality of sleep, among many other benefits.

Joe’s Final Comment

For many years I also considered that exercise was the main answer. I would train for marathons, work myself into the ground – pushing my body so hard that I repeatedly wrecked my muscles and joints; but still I would find that my unwanted weight crept back, and those damned “love handles”  would never disappear.

Now, at the age of 56, my body feels like it is at its optimal weight – the lowest level since I was in my teens. I never go hungry or actively control the quantity of food I eat – and I eat A LOT!

Before “going cold turkey” into a WFPB diet, I was starting to feel old and pretty pessimistic about my future, even though I was very conscious of my dietary intake and had been a vegetarian on and off for most of my life.

Now, my arthritis has all but disappeared. My joints no longer ache. I no longer get constipated or have the recurrent mouth ulcers and nose bleeds that I had for years. Getting in and out of the car, or up from sofas, no longer causes exclamations of pain. I feel like I have more energy now than I had years ago. My mental attitude is consistently positive and…I am really looking forward to the future.

Of course my and Terri’s claims about the health benefits of a WFPB diet are merely anecdotal; but without a personal experience of the power of plant-eating I would not be able to recommend it to other people. I just wish my parents had been able to enjoy its health benefits instead of the lingering and painful diet-related diseases that they endured.

If you have a personal story that you think would inspire others, let me know.
