Yes, there are sophisticated tests, which can evaluate, for example, how your body processes fats. An example for that is apolipoprotein E and certain combinations of genes there can help you be hardy and resilient so you could be 90 and eat what you want, or another combination will show that exercise has a dramatic effect on cholesterol and another combination, the ApoE4, shows that you are at greater risk of having heart disease. So if you know what your genetics are, you will know what to focus on and making specific changes for yourself.
