Episode 3253: Rachel Trotta unpacks decades of diet trends to reveal why the fat vs. sugar debate is more complex than it seems. Backed by evolving science, she argues that sugar, not fat, may be the real driver behind inflammation, blood sugar spikes, and long-term weight gain, urging a shift toward balanced, satisfying eating patterns grounded in whole foods. Read along with the original article(s) here: https://racheltrotta.com/self-improvement/fat-or-sugar/ Quotes to ponder: "Frequent blood sugar spikes, not fat, cause inflammation and atherosclerosis." "A diet with sufficient fat is more satisfying, physically and mentally." "You still need to eat lots and lots of vegetables. The point of a low-carbohydrate and high-fat diet is to avoid blood sugar spikes, not to eat as much cheese and meat as possible."
