Current weight: 270.4 lbs
From a NY Times article on exercise:
“We didn’t look at this, but it’s probably safe to speculate that it’s easier and more pleasant to exercise if you’re not already heavy.” I-Min Lee, a researcher at Harvard Medical School and Brigham and Women’s Hospital
This is one of those statements that instantly provokes the “well, duh” response. Nevertheless, I still think it’s a fact that is overlooked particularly by people who are not overweight.
The simple fact is that when you are overweight, typical forms of exercise (e.g. running, cycling, etc.) are not enjoyable. And it’s not just the fact that you’re carrying more weight and thus tend to tire out faster. These activities are actually uncomfortable. Try sitting on a standard road bicycle seat for an hour if you weigh 250 lbs. Not only are you exhausted but you’re also in serious pain. The unsurprising result is that exercise tends to be avoided.
The article points out what anecdotal evidence has shown for years: exercise, without any accompanying diet changes, is not generally very effective for weight loss. (Note I’m only discussing weight loss here. No one is disputing other benefits of exercise like improved cardiovascular health. ) Generally speaking, the best weight loss regimen stems from the old calories in/calories out formula. Eat less calories than you burn each day and you will eventually lose weight.
There does appear to be growing evidence that, once you’ve lost weight, regular exercise helps your body to metabolize food more efficiently and, in turn, helps to keep the weight off. Again, this is not exactly a ground-breaking conclusion. But this has nevertheless been a fact that I’ve been slow to understand.
When I began my weight loss efforts in earnest back in February, I knew I had to reduce my caloric intake to some extent. But I believed that I could achieve the majority of the weight loss through exercise as opposed to making significant changes to my diet. In my case, however, just the opposite has proven true. Although my exercise has been sporadic, I’ve been fairly strict in keeping my calorie count lower than what would be necessary to maintain my weight. The result has been slow (sometimes painfully slow) but steady weight loss.
Currently, my plan is to continue what I’m doing in terms of my diet. I do have a goal of returning gradually to a regular exercise program, but I’m doing that more for the cardiovascular benefits rather than weight loss.
