Fuel to the Fire

A fit individual can maintain a constant healthy bodyweight for an entire adult lifetime. The body finds its weight according to its activity level, and the diet adjusts itself to that via appetite. If there is less exercise, five extra pounds of useless weight may be gained, from storing more than is used. But it levels off. There is a lag time, then. But there is self-regulation.

Getting fat, very fat, should be no easier than getting very muscular. Both are functions of hormones and metabolism. Eating by itself won't do either. Neither will moving or not moving. There is a range that normal individuals have, within which they will gain or lose weight. After that, it takes exceptional effort or circumstances, or a profound genetic or hormonal disruption.

To get muscular, amino acids and glucose must be directed within muscle cells, guided by hormones. To get fat, free fatty acids and glycogen must be localized within fat cells. It is not the presence of amino acids or FFAs that dictate this. It isn't the presence of insulin per se. It is the receptivity of cells and the prevalence of hormones. A muscle cell takes in raw materials not because they are in the bloodsteam, but because its receptors have been activated or sensitized. Exercising a muscle does that. Then, if sufficient nutrients and the proper hormones, testosterone, HGH, etc, are in the bloodstream, muscle growth will occur. Same deal with fat. An excess of glycerol and insulin, in a generally insulin-resistant body, will result in the pervading corpulence of the current American population.

It isn't about excess calories anymore than being muscular would be. It's about the type of nutrients and the hormonal reactions. Some people are born to be powerful, some to be fat. The rest of us have to work at it, or fall into it by habits of lifestyle. It's not a moral statement. Only choices can be judged by moral standards. We might say, informed choices. That's why there is the Old Testament concept of unwitting sin -- it is treated differently by God. The harm is done, but the guilt is less. Those who are congenitally muscular may be proud, as those who are fat may feel shame or guilt. But not all blessings are earned, nor curses. The universe, like metabolism, is hormonal. There is balance, within a range.

Because muscle is made of protein, and fat is made of, uh, fat, people generally assume there is a cause and effect relationship. But perhaps we've seen the dudes with the protein powders straining away in the gym trying to bulk up those guns. Some of them do. But they usually look, to an informed eye, sort of puffy and soft, and always malproportioned. Unwitting sin. It's the opposite with the fatties. They think fewer calories rather than more grunting will do it. Yes, it will, sort of for a while, until they start eating again in the way they think is normal. But it's not, none of it, about calories, anymore than heat is about fuel. There's a lot of fuel in the world. Why isn't the world on fire?

Some of the work, you just have to do. Sometimes there's no help but what you give yourself. Sometimes there's help.

Here we are.

Be excellent.
