When it comes to obesity, which is more important: diet vs. exercise? Can weight be lost without exercise? The common explanations for the cause of the obesity epidemic put forward by the food industry and policymakers, such as inactivity or a lack of willpower, are not only wrong, but actively harmful fallacies. Subscribe to NutritionFacts.org's free e-newsletter and receive a recipe from Dr. Greger's brand-new cookbook, The How Not to Diet Cookbook: https://nutritionfacts.org/subscribe/ When I sat down to write How Not to Diet (https://nutritionfacts.org/how-not-to-diet/) I knew this “what triggered the obesity epidemic” was going to be a big question I had to face. Was it inactivity—just kids sitting around playing video games? Was it genetic? Was it epigenetic—something turning our fat genes on? Or was it just the food? Were we eating more fat all of the sudden, more carbs? More processed foods? Or were we just eating more period, because of bigger serving sizes or just snacking more? Inquiring minds wanted to know. This is the first in an 11-video series to answer this question, which I originally released in a 2-hour webinar earlier this year. If you can’t wait and want to get all of the videos at once, check out the webinar digital download here (https://drgreger.org/collections/downloads/products/obesity-epidemic-digital).

Subscribe to NutritionFacts.org's free e-newsletter and receive a recipe from Dr. Greger's brand-new cookbook, The How Not to Diet Cookbook: https://nutritionfacts.org/subscribe/ DESCRIPTION:The EPA safety limit on mercury in fish may not sufficiently protect pregnant women in the United States. This has led to a recommendation that fish-eating women get tested for mercury before considering getting pregnant. There is so much more mercury in fish compared to other foods that it can be used as a biomarker for fish consumption--see Hair Testing for Mercury (http://nutritionfacts.org/video/hair-testing-for-mercury/). How much mercury exposure is there from fish as compared to amalgam fillings and vaccinations? See Amalgam Fillings vs. Canned Tuna (http://nutritionfacts.org/video/amalgam-fillings-vs-canned-tuna/) and Mercury in Vaccinations vs. Tuna (http://nutritionfacts.org/video/mercury-in-vaccinations-vs-tuna-2/). Fish aren't the only source of toxic heavy metals, though. Mercury has been found in both high fructose corn syrup-containing products (see Mercury in Corn Syrup? (http://nutritionfacts.org/video/mercury-in-corn-syrup/)) and Ayervedic dietary supplements (Get the Lead Out (http://nutritionfacts.org/video/get-the-lead-out/)). There are also videos on aluminum in cheese (http://nutritionfacts.org/video/aluminum-in-vaccines-vs-food/), arsenic in chicken (http://nutritionfacts.org/video/arsenic-in-chicken/), and a thousand other nutrition subjects (http://nutritionfacts.org/topics/).
