How We Get Fat | Marc Bessler

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Question: Is sleep a factor in managing weight gain?

Marc Bessler: It may not be. Certainly you could argue that during sleep you’re not burning as many calories but I think that probably just enough sleep to be comfortable and not tired, there’s no specific number that I know of.

Question: Is weight gain hereditary?

Marc Bessler: Overweight, obesity is almost certain hereditary, about 70% of your weight is genetically determined and that’s identified from twin studies and things like that, it’s actually a closer correlation than height, your weight is gonna be most similar to your parents weight for the part than your height is gonna be similar to your parents height.

Question: If your parents are obese, how can you prevent becoming obese as well?

Marc Bessler: You gotta work really hard to make sure that your lifestyle and habits really, do everything you can to negate that and that means being really careful with your intake, being really careful with what you eat, how much you eat, when you eat it and your exercise and exercising regularly helps maintain your metabolism up because one of the things I was talking about before, regular exercise helps keep your metabolic rate up. It may not cause weight loss by burning off calories, but as you diet, as most people who are overweight diet, your metabolism slows, you take in less calories, your body uses less calories in response and that’s why people stop losing weight is their dieting, even though they keep their calorie count down. When you exercise it counteracts that metabolism rate decreasing by exercising you can keep your metabolism higher and therefore those less calories will end up in more weight loss ultimately. But if you don’t eat less, exercise by itself for the most part isn’t gonna cause weight loss.
