Different people will get different things out of knowing (and acting on) the knowledge of themselves that iamYiam provide.
For some people ‘best’ will mean improved sporting performance. For others it will mean living a longer life because of measures to target diseases that they are at risk from. For others it will mean just having a little more energy day-to-day because they’re avoiding foods that are likely to slow them down.
It could be all of these combined!
This is clearly a very subjective area, but to take just one example, let’s imagine that you are a little overweight and that no matter how hard you try you don’t seem to be able to get the scales to line up with your dreams. Wouldn’t it be great to know that your genetic setup is responsible for a delayed satiety signal being sent to your brain and that eating slowly could solve it, thereby encouraging you to eat less without feeling hungry?
Or maybe you find out that your weight is particularly sensitive to the amount of salt you eat or that your sensitivity to saturated fat is greater than average, which you could use as a guide to tailor your approach to dieting with greater chances of success. Armed with your genetic data, you could even see a nutritionist and build a dietary plan unique to your genetic code.
