Is Fitness All in the Genes?
Gene For Metabolizing Fats
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.

Fitness in Our Genes
A new study on the genetics of fitness is trying to find out if the body's receptivity to exercise is genetic or not.
The researchers have looked at thousands of individual segments of DNA, which are called single-nucleotide polymorphisms (SNPs), and identified a particular gene that responds to exercise by a measurement called maximum oxygen capacity.

DNA home tests
Some problems arise regarding DNA home tests about what happens after the results of land.
- Storage of sensitive genetic information. An open-source DNA testing site was recently used by the police to identify a killer.
- Emotional side effects after receiving confusing or life-changing results.
DNA home test variances
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:
- The companies are only looking at very recent DNA samples, from a relatively small group, in one specific database.
- The databases are skewed towards different parts of the world. Some have more American customers and other more British or Australian customers.
- These companies don't ask about the genetics of the past, and which of those past inferred genetic clusters we get our ancestry from.
- We probably inherit very few genes from our ancestors. DNA is inherited in “chunks” that break up the further back in time you go.
- There are ancestors from whom you inherit no DNA.

Exercise and our food choices
Taking up exercise could change your desire for specific foods.
One study found that novice exercisers start to have a diminished appetite for fattening foods. However...
The effects of physical activity
- Scientific studies reveal that a few people will lose a great deal of body fat when they start exercising. Others will gain, and most will drop a few pounds.
- Studies show that most types of exercise increase appetite in most people, tempting us to replace calories and preventing potential fat loss.
- Other evidence suggests that physical fitness may affect people's everyday responses to food. Some past studies show active people of normal weight displayed less interest in high-fat, calorie-dense foods. They may still enjoy the same food, but will not actively seek it out.

Different Outcomes
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.

Genetics And Nutrition
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.
Nutritional Genetic Testing
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.
