Evolutionary psychologist, Doug Lisle, PhD, social scientist, Jen Howk, PhD, and Nathan Gershfeld, DC discuss the following listener questions:  I am curious about the work of David Sinclair from Harvard about his anti-aging research. He makes some pretty fantastic claims. He does, for example, advocate for a plant-based diet, but then talks quite a bit about supplements, including prescription drugs like Metformin. I also heard him say that although plant-based diets are good, we must avoid foods that spike blood sugars - like rice and grapes. Aren't those whole foods? Grapes, really? What do they think of Dr. Sinclair's work...work considering or majoring in minor things? I’m on the highest end of a healthy weight range even on a whole natural foods diet composed of fruits vegetables whole grains and legumes, with at most 1 avocado per week and 1 tsp of flaxseed per day. No nuts or seeds. I’ve lost weight before by restricting and over exercising, but I couldn’t maintain it. However I felt much more confident at this lower weight (about 10-15 lbs thinner than I am now). As women there’s a lot of pressure to be thin. How do I get over my desire to be thin? Is this something I can ever get over? I think about it every day and am tired of thinking about this. Is the thicker persons' metabolism or spontaneous recovery different from the genetically skinny person? i.e. if your genetics figured out your survival success by having you eat more, weigh more and get more resources, won't your body be genetically predisposed to continue those successful survival instincts that helped in your survival before? I’m having difficulty distinguishing the difference between eating intermediately to grit myself through the extinction curve of a condition cram circuit and eating under the hunger drive. How do I know if I’m eating intermediately or eating under the hunger drive when I got through this process ? Is there like a rule of thumb you would suggest we follow e.g 1 plate of food then nothing for a couple of hours??     Copyright Beat Your Genes Podcast Host: Nathan Gershfeld, DC                            Interviewee: Doug Lisle, Ph.D. and Jen Howk, Ph.D. Podcast website:  www.BeatYourGenes.org True to Life seminars with Dr. Lisle and Dr. Howk : www.TrueToLife.us Fasting Supervision:  www.FastingEscape.com Intro & outro song: City of Happy Ones · Ferenc Hegedus
