There’s no more universal question than why do we get fat? What’s the answer to weight loss and achieving a healthy weight? Is the obesity epidemic because of high fructose corn syrup? Fast food and the abundance of cheap calories? Does fat make us fat, or not? What’s the best diet for humans? Mediterranean diet, paleo diet, DASH diet, or the smoothies, pumpkins and cookies diet? Pumpkin, num!
There’s also no issue that is more illustrative of the ill-understood reality that despite our common sharing of the human genome there are huge variables in (1) how we all metabolize fats, carbohydrates and proteins, (2) whether we store excess fat as energy and (3) where we store that fat on our bodies! While we’re always looking for some universal panacea for these things, the pharmaceutical industry teaches us that humans vary so much that certain drugs may only be effective on 20% (or less) of people.
We would probably be shocked to learn that most drugs don’t do anything good for the majority of the people who use them.
In the study of human biology we’re still very, very, VERY early on in our studies of how things work and we are still figuring it all out. It is extremely likely that in coming years we will learn things that will turn our understanding of nutrition, weight and obesity on its head. One of the exciting things being researched right now is the overall influence of our gut bacteria, the varied 100 trillion bacteria in our gut (our microbiome), on our health.
I found this discussion of the early research on this fascinating. Maybe you will too.
