It has been previously argued that such a scenario is unfeasible because under such strong selection any gene favouring fat deposition would rapidly move to fixation. Hence, we should all be predisposed to obesity: which we are not. The genetic architecture of obesity that has been revealed by genome-wide association studies GWAS , however, calls into question such an argument. Obesity is caused by mutations in many hundreds maybe thousands of genes, each with a very minor, independent and additive impact. Selection on such genes would probably be very weak because the individual advantages they would confer would be very small. Hence, the genetic architecture of the epidemic may indeed be compatible with, and hence support, the TGH. To evaluate whether this is correct, it is necessary to know the likely effects of the identified GWAS alleles on survival during starvation. physical effects of starvation

What Would Happen If You Stopped Eating?Effects of Malnutrition on Child Development Article by: Emily Corso Food insecurity often accompanies homelessness and leads to adults and children alike being malnourished. In recent years, physical effects of starvation number of households that have suffered food insecurity due to financial hardships has skyrocketed, with reported numbers of families starvtion food insecurity in the United States being the highest it has ever been since regular monitoring first began in Howard, Malnutrition has particularly adverse effects on children, as it can affect both their mental and physical wellbeing.
Good nutrition is essential for the physical growth of a child, and bad nutrition can have irreversible effects if left untreated. Vitamin D, for instance, is essential to bone health, and when a child experiences deficiency they may suffer from a condition called rickets, in which the bones are too soft to support the weight of the growing child and causes bow leggedness.
INTRODUCTION
Malnutrition can also cause a child to be overweight as a result of poor quality food that is lacking in nutritional value. When children are overweight or obese, they are also at greater risk for other health issues such as high blood pressure and high cholesterol, and other conditions such as asthma, sleep apnea, and type 2 diabetes Belsky et al. Malnutrition can also have adverse effects on cognition as well as mental health. Those same vitamin deficiencies that cause physical health problems can also hinder the development of the brain in growing children. For instance, children who are malnourished are more likely to perform effectw in school, to repeat a grade, and also show deficits in working memory as well as selective attention Physical effects of starvation et al.

Malnourishment can also lead to a number of emotional and behavioral disorders in children. For instance, higher rates of anxiety and depression are found consistently in children that are experiencing food insecurity Belsky et al. While these could reflect the stress of being in an impoverished family, however, the effefts are exacerbated by poor nutrition.
For instance, serotonin is a neurotransmitter that regulates mood and is commonly known as the happy hormone. In order to produce serotonin, the body must have an adequate amount of carbohydrates.
The emotional and behavioral disorders that many children develop as a result of malnutrition also make it difficult for children to navigate social situations among their peers Howard, For example, children who suffer from anxiety often struggle with making friends in school, and it can lead to feelings of isolation and depression.
Additionally, malnourished children who are overweight may experience low self esteem attached to feelings about their physical appearance, which can also physival of feelings of insecurity and self-consciousness. Works Cited Belsky, D.]
