Happy New Year! Did you resolve to lose weight this year? Running burns a ton of calories so it should be a great way to melt off the pounds, right? Well, maybe not. Dr. Kyle Flack, a weight-loss researcher from the University of Kentucky, conducts studies on how the body responds to exercise and how much you really need to work out to work off those extra pounds, and it turns out you need to work out a lot more than the current recommendations suggest. Dr. Flack was recently featured in a New York Times article on exercising to lose weight and he shares his research results and provides insights on why weight loss isn’t as simple as burning more calories than you take in. He explains how body chemistry can seemingly work against us, thwarting significant weight loss, especially for fitter people, and why it’s not uncommon for people to actually gain weight while training for a marathon. Through his studies, Dr. Flack has found that people overcompensate for the calories they’ve burned pretty consistently, and he shares what the average calorie overcompensation amount is and how much exercise time is required to overcome it to really drop pounds. He also talks about how long it takes to make exercise a habit, he compares strength training to aerobic exercise for weight loss potential, and also reveals whether it’s possible to build muscle and lose fat at the same time. If your goal is to lose or maintain your weight through your running, this is definitely a must-listen-to episode! Kyle Flack grew up in a small town in Vermont where, as a 4-year starter on the varsity football team, earned All-State honors twice and won two state championships. He left to play college football at Ferrum College in Southwest Virginia, earning a BS in health sciences 4 years later. He continued his education at Virginia Tech in the Department of Human Nutrition, Foods, and Exercise, where he earned his PhD in 2014.  Upon beginning grad school, Kyle also turned over a new leaf in terms of his exercise routine, going from 280-pound power-lifting football player (who got winded walking upstairs) to a runner. He devoted an entire winter and spring to this newfound training, lost 40 pounds, and completed his first marathon, Vermont City Marathon in 2008.  From there he was addicted, running two marathons each year for the next 5 years throughout grad school and dropping another 30 pounds. Each marathon was a new learning experience, a new opportunity to get better, and always ended with the goal or running the next marathon faster!  After grad school, and after finally reaching that sub-3:30 goal (he did the Marshall University Marathon in 3:27) Kyle shifted his attention to triathlons, which he has been at since 2014. Kyle completed a Post-Doctoral research fellowship with the USDA in Grand Forks North Dakota from 2014 to 2017 and has since been an Assistant Professor at the University of Kentucky in the Department of Dietetics and Human Nutrition since 2017. Kyle is an RD (registered dietitian) and primarily focused on researching weight loss physiology, how exercise may affect eating behaviors, and how exercise can be more appropriately used for weight control.       Questions Kyle is asked:   4:52 You are a researcher at the University of Kentucky specializing in how exercise affects eating and weight loss.  And you don't just study it, you used running to lose weight yourself.  Can you share your experience?   7:27 You were already an athlete with football so it wasn’t like you were obese or overweight and just wanted to lose weight by running?   7:58 Let’s get into some weight loss science.  It seems that weight loss should be easy. It’s "calories in and calories out."  What makes it more complicated than that?   10:00 When you lose weight, you’re obviously lighter so there’s less of you to move around. Is that correct?   10:30 Why isn't exercise generally effective for weight loss?   11:37 Overcompensating for calorie expenditure due to exerci
