It seems as if genetics gets into everything these days. Evolved genetic responses have been theorized to be responsible for the capacity of living beings to shift the body’s nutrient distribution priorities from reproduction to tissue maintenance during times of low food intake. There has also been speculation on the role of genetics and gene markers in weight, including the possibility that obesity genes might be responsible for excess weight. Of course, this is all speculation, so people should not trade in their weight loss pills for genetic therapy just yet.
Overview
It is no secret that genetic factors, markers, strands, and responses play a huge role in the life of the average organism. Human beings and practically every other creature on the planet have a number of reactions and responses embedded into the most basic aspects of the genetic code. It seems to play many roles, though most of it is speculation and lack any solid trials to see whether the theories are correct. This includes weight loss, though genetics is not a replacement for a better diet, exercise, and weight loss pills.
The science
Intra-abdominal fat, for example, seems to be genetically determined – that is, how much of one’s body fat actually gets stored there may be written in the genetic code. There has also been speculation that the Basal Metabolic Rate, which is lower than normal in people who tend to gain weight more easily than others, might be determined by genetic factors. Appetite, something that many weight loss pills try to curb, has also been linked to hereditary factors. Genetic factors are known to have an effect on how much fat and muscle gets piled on to the body, though how much control it has is unknown. Finally, thermogenesis – the energy required to break down food during digestion – seems to be affected by genetic triggers. In simple terms, losing weight may have a number of aspects linked to genetics.
Still, one should not completely abandon the use of dietary supplements. It is true that obesity genes play a role in the functioning of the body, and many factors that are touched on by weight loss pills appear to be governed by genetic triggers and responses. However, many of these triggers are not “set in stone,” and do not impose strict limits on the body. These genetic factors may make it harder or easier, depending on the person, but these do not make weight loss goals impossible.
