• For Sarah weight loss maintenance is her favorite element that the Paleo lifestyle offers
• This week Stacy and Sarah will be talking about the obesity paradox
• Both Stacy and Sarah receive questions from listeners about hitting a weight loss plateau, and this is where getting healthy to get thin becomes a core idea
• Research is starting to show that having that extra 20 to 30 pounds may actually make you healthier - the healthiest place to be is overweight, not obese or underweight
• The studies that have been done on this concept
• The obesity paradox came from the observation that people who have a BMI of 25 to 30 (classified as overweight) have the lowest rate of all cause mortality
• Stacy points out the question - how is the ideal weight defined? and by who?
• As studies dig into this concept, they have found that obese people have a higher risk of many diseases, but obese people once they have a chronic illness they have a higher chance of surviving it
• There are two sides to this
• One, that being overweight or obese increases your survival from chronic illness, even though it increases chronic illness rates
• And that being overweight is this magic place where there is a much lower all cause mortality
• The sweet spot - where we have the longest life span and the lowest disease risk, on average, is slightly overweight, not underweight or obese
• Sarah is not a fan of the BMI, and Stacy has her doubts in its validity as well
• Stacy pointed out some examples of BMI limitations
• Sarah explained why the BMI is still used, and notes that some medical communities are trying to use body fat percentage as a new measurement
• There is actually a recommendation to hit the senior years a little bit heavier and the medical benefits this weight brings
• The weight we naturally gain as we get older - does it prepare us for those older ages where it is beneficial to be heavier?
• Another study that was done on fat storage and longevity
• The study was done on yeast to determine how having an increase in body fat has a genetic effect prolonging life span - which might be behind the obesity paradox
• What Sarah finds fascinating about the obesity paradox is what this body of research is starting to show
• That 10 to 30 pounds that just won't come off is probably a lot better for us to keep on our bodies and we should learn to embrace it
• We don't need more weight loss strategies or tools - we need to instead redefine what the goal is
• Stacy's thoughts on redefining the goal to better fulfill optimal health
• We don't need to have one box that defines what looks attractive - it is ok for us to look different, and for optimal health to take different shape in different body styles
• We will be back next week with some more awesomeness, and will possibly keep discussing this topic
• Thanks again for listening!
