## Resource

If you've spent years hopping from one diet to the next: low fat, then low carb, then keto, then intermittent fasting, you're not alone, and you're not failing. The truth is, the diet world has been cycling through the same promises, the same villains, and the same disappointments for nearly a hundred years. And most of us never stop to ask why. Join Holly and Jim as they do something they've never done before on the show: step back and take a decade-by-decade look at almost 100 years of dieting history. From the 1930s to the GLP-1 era of today, they trace how we went from counting calories to carnivore diets and what it all actually taught us (or didn't). This one is equal parts fascinating, a little humbling, and surprisingly fun. Whether you're a diet history nerd or just someone who's tired of starting over, this episode will change the way you think about every diet you've ever tried. Discussed on the episode: The three-category system Holly and Jim use to classify every diet, and why one category might describe your current eating plan The diet from the 1930s that your favorite wellness influencer is basically still selling today Why the decade that got everyone obsessed with fat-free foods may have actually made obesity worse The weight loss medication that came before GLP-1s, and the dramatic reason it was pulled from the market Which diets from the last 100 years actually have the science to back them up The rapid-fire verdict: best diet, biggest mistake, and most underrated program of the century What GLP-1 medications are changing about the way we think about diets, and why Holly has one big worry about where this is all heading Jim's closing thought that reframes everything you think you know about why diets succeed or fail
