Is Fitness All in the Genes?
A particular gene known as ACSL1 seems to play a role in how a body metabolizes fats and subsequently affects exercise response.
The findings, though preliminary, do point towards exercise benefits being genetic. Still, exercise has a multitude of benefits and cannot be discarded by individuals who do not have a certain type of gene.

Some problems arise regarding DNA home tests about what happens after the results of land.
Many who have done a DNA home test begin to question their family heritage and wonder if they might have been misled. However, taking DNA tests from different companies reveal wildly varying results. There are a few reasons for this:
We're all different. If we are all on the same weight-loss diet, there will be various outcomes. Some people will lose a lot, some will lose a little, and a few will even gain weight.
Scientists are continually finding links between genetics and nutrition. Many of us have a gene called FTO that makes us more likely to be overweight. You can get a genetic test to tell which variant of the FTO gene you happen to have.
However, scientists who study the genetics of nutrition think it’s premature to base nutritional advice on your DNA. That FTO gene, for example, has only been shown to make a few pounds’ difference in body weight.
The coded messages of your DNA are billions of letters (nucleotides) long. Personalized nutrition companies only care about a few of your DNA letters and can tell you which "variant" you have at each of those locations (known as SNPs) along your DNA strands.
Genetic testing companies can learn what SNP variants you have by supplying them with a vial of spit.

Historic evidence suggests that for many thousands of years, human beings were more active and stronger than today.
The early humans had increased movement and activity, like going for long and tiring hunts, walking long distances that took weeks, making the prehistoric humans fitter than the best athletes today.
Technological breakthroughs have reduced our activity to a great extent ( vacuum cleaners, washer-dryers, self-cleaning ovens, and even cars).
The rise of the internet gave us a whole lot of technology, curbing our need to move even more.
