Dear Cuddles,
The ultimate answer to your question is that you must engage in contined cardiovascular exercise to maintain your end of trail, end of hike, weight.
Here’s why.
Human beings have been described as the second best endurance animals on earth, second only to the wolf.
Like the wolf, we are designed to move long distances daily, at low speeds. The wolf tracks game herds in this manner. We are built to do the same.
It can be said without exaggeration that human beings, on the whole, are designed to travel 20-40 miles daily, day after day. We don’t live this way now, but, nonetheless, it is what our bodies are designed to do.
When we walk long distances daily, our bodies perform in peak fashion. Our bodies increase their ability to use fat as an energy source by increasing the amount of enzymes in our muscles that perform that function. Simultaneously, as more blood is needed, to carry the fat and other nutrients, our circulation systems grow in order to accomodate that need; while the muscles themselves grow in order to accomodate the need for more strength. (See: hikers’ legs.)
When we stop moving, as a permanent lifestyle change, as one might do when one ends a long distance hike, our bodies shut down. They get sluggish. The muscles atrophy in size because the demand for strength previously placed upon them is gone; and the enzymes that convert fat to energy are less frequently and copiously produces. As we devolve into a lifestyle of sitting still or moving little, we rely mostly on carbohydrates for energy, and crave them when when we get low, rather than covert to fat burning, because our movements are too infrequent and unsustained.
And then the horror sets in. Not burning fat, we crave carbohydrates, eat too many, and add the excess to our fat supply, while we live lives that do not demand, require or create the burning of fat. At this point, we are only adding. By now, what we eat is almost irrelevant, because we have shut down the fat burning system, while continuously adding to the fat supply.
What is critical to good health, fat burning, living at the weight you wish to live at, is near daily cardiovascular exercise (5-6 days per week).
At one time, as an experiment, I tried walking an hour a day, off the trail. Eventually, I settled upon walking six days per week, one hour per day, or three miles, for a total of eighteen miles per week. The result? At that rate, I lost ten pounds per month.
Later, I experimented with the system, because I felt like I was just getting started after an hour’s walk and that my body wanted more. So, I did the following: Three walks per week, one for one hour (3 miles), one for two hours (6 miles), and one for three hours (9 miles). The result was exactly the same, a loss of ten pounds per month, but I enjoyed this better, because the longer walks got deep into my bones and lower abdomen, and seemed to strengthen my trunk and shoulders, as well as my legs.
A few years later, I read somewhere that walking two miles per day, which should translate into forty minutes daily,
and fourteen miles per week, would result in an individual losing one hundred pounds over the course of a year. My own experience of walking eighteen miles weekly and losing ten pounds per month, which would translate to one-hundred-twenty pounds in a year, would seem to support that contention.
For reading, I would suggest the book, FIT OR FAT, by Covert Bailey. He explains how the human body utilizes fat at length,in a manner which is both easy to read and completely absorbing.
