RESEARCH CORNER - A very large (over 6400 people from 29 countries) study shows that a decline in adult metabolism doesn't actually occur until about age 60. This means that the gradual weight gain that typically starts happening to most of us at around age 30...it can't be blamed on a 'slowed metabolism' as we often say. So what can we 'blame' it on? The research study did not attempt to directly answer this question - but my opinion would be a simple increase in caloric intake as the main factor (with less overall activity as another variable). Generally speaking...we eat too much food folks, and much of it is not as healthy as it should be. My own personal experience with weight loss has definitely illuminated the fact that even when we think we are not eating much in the run of a day, we typically are still taking in too many calories.
For instance, I currently need about 3000 calories to maintain my weight, when I was in the process of losing weight I measured a lot of my food for accurate caloric counting - so that I knew for sure I was consistently staying about 500 calories below my maintenance calories, literally everyday - and it worked. What I found quite interesting was that a typical meal could EASILY be close to 1000 calories (or more), an unhealthy evening snack (e.g. chips) could pack on several hundred calories without breaking a sweat, and going for your money's worth when eating out...well you don't even want to know the result of that one. I'm not a dietitian, I'm a kinesiologist, so while I am not trying to tell people how to lose weight - I am attempting to illustrate just how easy it is to take in more energy than we expend. Keep in mind that many people, especially women, usually need much less than 3000 calories per day to maintain body weight -- making it all that much easier to over-consume when you choose to eat in the 'average' Canadian way.
Metabolic rate remains stable all through adult life, from age 20 to 60 years old.
