From an evolutionary perspective, we eat food because we need energy to live. Many people are under the preconceived notion that we eat because we need protein, vitamins, and fat. While it is true we obtain those secondary benefits, they are not the reason why we eat food. Energy can be obtained from carbohydrates, fats and, under specific conditions, proteins. Energy can be efficiently obtain through the ingestion of starches which contain Amyloplasts (McDougall, 2012). Amyloplasts are the storage organs plants use to store high amounts energy during periods of inactivity. Green and yellow vegetables are not true starches. They contain trace amounts of starch and therefore are not optimal for obtaining energy. Fruits also are not starches.

Majority of obese people eat a diet consisting mainly of grease, meat, and dairy. The foods that fall into these three categories have high amounts of fat and low amounts of energy stored inside them. Fruits and vegetables are almost non-existent in the diets of obese individuals. The few fruits and vegetables that these people consume are not starchy vegetables. Instead, their energy comes from fat and proteins. As a result, Leptin, a hormone secreted from fat cells in proportion to mass (Bennet, 2015), floods the brain which produces feelings of delayed satiation and lethargy. Consequently, these people gain mass in an attempt to eat more food to feel satisfied. When people engage in this compensatory practice over a long period of time, they become …show more content…
In the state of Yucatan is the city of Merida which is the most populated city in South Mexico with contains about one million residents. Researchers went to Merida and conducted an experiment of elementary students from sixteen different schools to test the effects that having low income may impact the students when it comes to their weight, height, and health overall. During the study the researchers recorded the students BMI, their height, ethnicities which were all calculated by age group, and the total income of the student’s parents.In the results of the study more than half of the students were overweight or obese. Students that were tested lived in a high urbanized area. In this area there is a lack of physical land which wouldn’t allow the students to be as active as the students that were living in North Merida where there is much more space available for physical activity. Out of all sixteen local public schools students were only allowed one session per week for physical active which means if the parents wanted their child to be more physically active it would have to cut into their expenses, which is money that many low income parents can’t offer. Residents in North Merida, which are of higher income, are surrounded by more
