I have a tendency to be overweight and for the past few years, my blood glucose levels have taken me to the edge of diabetes. I like to eat and my social obligations often push me there. In addition, there are always a few tapas here and there, a small glass of wine or the traditional Saturday vermouth. Nothing too bad, but it’s enough to force me to take measures to control my blood sugar levels and my weight.

In the morning, I ride a stationary bike for a while. When I started this morning activity, I lost two pounds in two or three weeks. I then started to lengthen the pedaling time. I lost two more pounds. But since that time – and I’ve been doing this exercise for almost two years now – my weight has steadfastly stayed at a stable level. No matter how much physical effort I make, I can barely reduce it. And I can’t afford to pedal any more. I don’t have enough time during the day, nor during the night either.

All of this makes me uncomfortable, for two reasons. First of all, because of the effects of this situation, or more precisely its lack of effects. It is disheartening to get on a bicycle early in the morning, to pedal like an unhappy man for more than an hour, and finally stay at the same weight as before. All I can do is lose the weight gained during the week during the week.

Then, the apparent lack of physiological logic in all of this bothers me. I teach physiology and in the part of the program in which I talk about energy balance, I explain that when activity increases, metabolic expenditure also increases. Therefore, if the absorption of energy in the form of food is constant, this increased metabolic activity should lead to a reduction in the energy available for growth. And this, to the point of even becoming negative. Why then does my weight not decrease further?

It turns out that when we increase our physical activity, our body adapts to the situation and loses less mass than we could hope for. I tend to be cold except on the hottest days of the year. And I am colder in the mornings when I have done intense physical exercise. This is the reason why I think that what I charge my metabolism in the form of exercise, it recovers in the form of heat: it makes me feel cold.

According to anthropologist Herman Pontzer, of Duke University in the United States, by increasing physical activity in the long term, daily energy expenditure also increases, but less than what one could hope for. In addition, as the activity increases, the total daily expenditure 먹튀검증 increases less and less, until it becomes almost constant. This means that if this expenditure is more or less constant and the organism develops more physical activity, other expenditure items must be reduced. And this reduction takes place, in principle, at the level of non-essential functions.

It is precisely in the Italian capital, in 1960, that apartheid South Africa had participated in its last Olympic Games, twelve years after the coming to power of the National Party, mainly Afrikaner, in 1948. Because apart from attempts to reach out, the pressure never stopped. In 1968, South Africa was invited to the Mexico Games, but 42 countries from Europe, Asia, Africa and the Caribbean threatened to withdraw so that the International Olympic Committee (IOC) canceled its invitation before excluding from its movement the segregationist country in 1970, soon followed by the International Football Federation (FIFA) in 1974 and the International Athletics Federation (IAAF) in 1976.
