Control your body weight: If not most systems in the human body are regulated. The normal level of the body temperature is about 98.6 Fahrenheit. Keep your body warm if you are feeling cold or when you shiver, this is when your fingers and toes get so cold. Get rid of the excess heat by going into the heat or exercise and make your body sweat which increases the blood flow to the extremities.
So what about body weight? It is now well established that human body weight is regulated after the three decades of research and endless argument in the journals. It is more accurate to say that body fat percentage is regulated.
In humans, studies have showed that metabolism would be slow more than you would predict for the weight loss which could also go up when you overfed them. Depending on your appetite and activity, your body weight would change accordingly. When people are on diet, the activity would tend to increase and appetite would go down when you overfed them. This will tend to affect your body weight or body fat. The body is more or less trying to maintain a given level of body fat, the level called as the ‘set point’.
A given individual might settle at one body fat level if they were inactive and eating the modern American diet and settle at a different and generally lower body fat level if they start exercising and eating better. They would regulate just fine around those settling points i.e. their body weight would fluctuate a little bit but they would have to change their habits to alter the settling point very much.
The idea of a settling point is probably a little closer to the truth that people don’t continue gaining weight indefinitely based on their environment they gain weight and then stay pretty stable around that new weight.
The main idea that I want to convey is that within some range the body appears to ‘defend’ i.e. to try and maintain that set point within a certain range. The body can any how adjust metabolic rate, appetite and a whole host of other systems up or down to try and defend against changes in body fat or bodyweight.
