“We are not all created equal when it comes to fat”
- Analysis of DNA suggest that there are variations on certain chromosomes that are linked to fatness.
- We can’t change our genes, but science is learning that we can influence how they affect our health.
- For example, individuals with variations in a gene called FTO tend to desire high-calorie foods more and have more fat as a result.
- This gene causes an almost twofold increased risk of obesity compared with those who do not inherit the gene variation.
- Genes are strong, but don’t have the final say.
- If you have such a variant, are you doomed to a life of flabbiness?
- The good news is that unless you have one of the very rare genetic mutations that undeniably cause obesity, your genes are just one factor in your weight profile.
- In the end, daily actions matter more.
- How much we decide to eat, what we eat, and how much we choose to exercise will, in the majority of cases, trump our genes.
- For example, people with the risk version of FTO respond just as well to weight loss interventions as everyone else.
- Carriers of certain ‘fat genes’ are known to be on average 6.6lb heavier.
