To Avoid Overeating on High-Calorie Foods, Fill Up on Nutrient-Rich Ones

An important corollary to the principle of limiting high-calorie food
is that the only way for a human being to safely achieve the benefits
of caloric restriction while ensuring that the diet is nutritionally ade­
quate is to avoid as much as possible those foods that are nutrient poor.
Indeed, this is the crucial consideration in deciding what to eat. We need to eat foods with adequate nutrients so we won't need to consume excess "empty" calories to reach our nutritional  require­
ments. Eating foods that are rich in nutrients and fiber, and low in
calories, "fills us up," so to speak, thus preventing us from overeating.
To grasp why this works, let us look at how the brain controls our dietary drive. A complicated system of chemoreceptors in the nerves lining the digestive tract carefully monitor the calorie and nutrient density of every mouthful and send such information to the hypo­ thalamus in the brain, which controls dietary drive.
There are also stretch receptors in the stomach to signal satiety by detecting the volume of food eaten, not the weight of the food. If you are not filled up with nutrients and fiber, the brain will send out signals telling you to eat more food, or overeat.
In fact, if you consume sufficient nutrients and fiber, you will be­ come  biochemically  filled (nutrients)  and  mechanically  filled (fiber),
and your desire to consume calories will be blunted or turned down. One key factor that determines whether you will be overweight is your failure to consume sufficient fiber and nutrients. This has been illustrated in scientific studies.
How does this work in practice? Let's say we conduct a scientific experiment and observe a group of people by measuring the average number of calories they consumed at each dinner. Next, we give them a whole orange and a whole apple prior to dinner. The result would

we can still maintain optimal health by taking a pill, powder, or other potion. However, this is a false hope, a hope that has been silenced by too much scientific evidence. There is no magic. There is no mir­ acle weight-loss pill. There is only the natural world of law and or­ der, of cause and effect.  If you want optimal health and longevity, you must engage the cause. And if you want to lose fat weight safely, you must eat a diet of predominantly unrefined foods that are nutrient-
and  fiber-rich.
ing to get nutrients
be that the participants would reduce their caloric intake, on the aver­ age, by the amount of calories in the fruit. Now, instead of giving them
two fruits, give them the same amount of calories from fruit juice.
What will happen? They will eat the same amount of food as they did when they had nothing at the beginning of their meal. In other words, the juice did not reduce the calories consumed in the meal — instead, the juice became additional calories. This has been shown to occur with beer, soft drinks, and other sources of liquid calories.30
Liquid calories, without the fiber present in the whole food, have little effect at blunting our caloric drive. Studies show that fruit juice
and other sweet beverages lead to obesity in children as well.31
If you are serious about losing weight, don't drink your fruit — eat it. Too much fiber and too many nutrients are removed during
juicing, and many of the remaining nutrients are lost through pro­
cessing, heat, and storage time. If you are not overweight, drinking fresh-prepared juice is acceptable as long as it does not serve as a sub­ stitute for eating those fresh fruits and vegetables. There is no substi­
tute for natural whole foods.
There is a tendency for many of us to want to believe in magic. People want to believe that in spite of our indiscretions and excesses.
