Brought to you by Sundays for Dogs ultra-high-quality dog food, AG1 all-in-one nutritional supplement, and Shopify global commerce platform, providing tools to start, grow, market, and manage a retail business.Sam Corcos (@samcorcos) is the CEO and Co-founder of Levels, an a16z-backed startup that shows you how food affects your health using continuous glucose monitors and other biosensors.Please enjoy!*This episode is brought to you by Sundays for Dogs, ultra-high-quality dog food without the prep or mess! I want to give my pooch, Molly, the best of everything. This is especially true when it comes to the ingredient quality of her food. But most healthy dog foods are an expensive, frozen mess. They’re a hassle to thaw and serve, and the prep work eats up time I’d rather spend hiking with Molly. Sundays for Dogs solves my problem with air-dried, high-quality dog food I can store and pour right from my pantry.​The magic behind Sundays for Dogs is in their proprietary air-drying method. To lock in nutrients, they gently dry the meat, low and slow. Unlike other dry brands, which are filled with hyper-processed grains and synthetic vitamins, Sundays for Dogs uses only all-natural poultry and USDA-grade beef. And meat makes up 90% of their recipes. The other 10% are fruits and veggies, ingredients you’d find at the farmer’s market, not at the pharmacy.Get 35% off your first order of Sundays for Dogs by going to SundaysForDogs.com/TIM or by using code TIM at checkout. Upgrade your pup to Sundays for Dogs and feel great about the food you feed your best friend.*This episode is also brought to you by AG1! I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so.
