Is Fitness All in the Genes?

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.

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.

Paleo concept

Humans evolved on a diet very different from today's eating habits. To be healthier, leaner, stronger and fitter, we must re-think our diet and remove some of the food groups we ...

What to eat
  • Animals (especially a "whole animal" approach, including organs, bone marrow, cartilage, and organs).
  • Animal products (such as eggs or honey).
  • Vegetables and fruits.
  • Raw nuts and seeds.
  • Added fats (like coconut oil, avocado, butter, ghee).
What to avoid
  • Grains, although research suggests eating whole grains improve our health and appear to be neutral when it comes to inflammation.
  • Heavily processed oils, such as canola and soybean oil.
  • Legumes, although research suggests the benefits of legumes outweigh their anti-nutrient content. Cooking eliminates most anti-nutrient effects. Some anti-nutrients may even be good.
  • Dairy.
