30 | Why trying to "lose weight fast" is not the flex you think it is.
from More Than A Number | Lose Weight, High Protein Diet, Low Carb Diet, Meal Prep, Lose Weight Fast · host Sam Barone | RD, Weight Mgmt Specialist, Diet Culture Rebel
Hey friend, welcome back! If you’ve ever felt like you can lose weight—but you can’t keep it off—you’re not alone. It’s one of the most common frustrations I hear from women, and in today’s episode I want to unpack what’s actually happening in your body when you try to lose weight, especially when you try to lose weight fast. Most people assume weight regain is a discipline problem. We tell ourselves stories like “I just don’t have enough willpower,” or “I always gain it back.” But the truth is that science tells a very different story. When you lose weight, your body doesn’t see that as a victory—it sees it as a potential threat. Throughout human history, food scarcity was a real danger, so our bodies evolved powerful biological systems designed to protect us from starvation. When body weight drops, those systems kick in. One of the biggest changes is something called metabolic adaptation. As you lose weight, your body becomes more energy efficient and burns fewer calories than expected. This means the calorie deficit that helped you lose weight in the beginning may stop working later on. At the same time, your hunger hormones shift. Leptin (your fullness hormone) decreases, while ghrelin (your hunger hormone) increases. Research published in The Lancet shows that these hormonal changes can persist for a year or more after weight loss, meaning your body may still be pushing you to regain weight long after the diet ends. This creates what researchers call an energy gap: your body needs fewer calories, but your appetite is stronger. The good news is that long-term weight maintenance is possible. Research from the National Weight Control Registry shows that people who successfully maintain weight loss rely on consistent habits—regular physical activity, resistance training, prioritizing a high-protein diet, structured meals, and ongoing self-monitoring. The goal isn’t to lose weight as quickly as possible. The goal is to lose weight in a way that your body can maintain long-term. And when you understand the biology behind weight loss, something powerful happens: the shame disappears, and strategy can finally take its place. *************************************************************************** FINALLY move the chains on your weight loss goals and start making progress with your Winning at Weight Loss Breakthrough Session!
