Does less exercise contribute to human obesity?
In short, probably not.
For years we have thought that our “sedentary lives” have been a major contributor to our ever increasing obesity epidemic.
In fact, obesity is much more related to the foods we eat, and much more related to quality rather than quantity. It may be hard to believe, but the evidence is starting to come in. If we study the research closely, we may find that it’s always been there.
Experiments have been conducted on indoor cats for multiple generations (over fifteen) to see what happens if they are provided their natural diet (in relatively unlimited quantity), while living a totally indoor life of ease.
According to the current human hypothesis, they would become obese and suffer from related health problems. That is certainly the case when pets are fed processed Frankenfoods that come in cans and bags.
Now, change the diet, and feed these animals only what nature evolved them to eat. For cats, this is raw whole ground-living animals. The result: no obesity, self-regulation of food consumption, perfect dentition, beautiful coats, and no need to ever visit a vet.
Next, we have gorillas. Case University and Cleveland Zoo took a nature-based approach to solving the riddle of obesity and heart disease, using caged gorillas as a model. By switching to foods nature evolved these primates to eat, their weight automatically normalized, and their health returned, even though they ate more food more often than when they ate Frankenfoods.
