All species live within their niches, which are always primarily energy niches, in which an organism can obtain enough energy and preserve it for long enough to produce viable offspring. There are usually energy tradeoffs; efficiency could be sacrificed for rate of ingestion, so that efficiency was reduced but input was increased enough so that the increased cost of obtaining it was worthwhile, such as with . The primary measure of an organism’s success is its energy surplus, which is related to resilience. As an example, today a trout can live in a fast-moving current where food quickly arrives, which is efficient from an input perspective, but the energy spent swimming to maintain a presence in the current reduces the net energy surplus. A slower stream will provide less food per unit of time, but it also takes less energy to live there. In trout studies, the dominant trout will live where the optimal energy tradeoff exists, which leads to the greatest energy surplus. Less dominant trout will be pushed into the faster water, and the least competitive trout will be pushed into calm water and slowly starve. No species will last for long if it does not have a high enough energy surplus so that it can survive the vagaries of existence. The energy surplus issue has not been emphasized in biology during the past century, as the “” of a species has been emphasized, but it is the variable for understanding species fitness.
In a striking similarity to the of evolutionary innovations, many human traits are vestiges of our history but have yet to disappear, but various social managers have used them to exploit the masses. For instance, the has a and developed because those were the most energy-rich foods that existed. But the incredibly high sugar and fat content of processed food vended by Western agribusiness companies plays to those biological proclivities in the name of profit. Diets based on such foods are disastrous for human health, and industrialized peoples, led by the USA, are the . Similarly, in-group "loyalty" (to fight the out-group) is a that arose to ensure survival. Ever since the , a goal of social managers has been forming that in-group cohesion to battle the out-group. There is not much sentient about it. As the and have made clear, people can be arbitrarily split along almost any lines and form an in-group and out-group, and the out-group will then be treated terribly. Darwin's "from the war of nature" comes "higher animals" conclusion in his is mirrored in the work of Marx and Hitler, in that they believed that human "progress" was produced by one social group violently prevailing over another. Hitler avidly read Marx, and may be how he received his "revolutionary" ideas.

Fast food is normally high in calories which results in eating too much calories. It can lead to an extra weight gain and ultimately obesity. Research has revealed that people having habit of eating fast food consume more calories as compared with people who are not habitual of eating fast food. People eating fast food, most of the time, also consume extra fat, sodium and saturated fat, while consuming less fruits, milk and vegetables.
