Why We Eat (Too Much): The New Science of Appetite

This book is a total game-changer for anyone tired of the endless 'eat less, move more' mantra. Jenkinson manages to explain the complex interplay of hormones like leptin and ghrelin without making you feel like you're sitting in a dry biology lecture. Personally, the concept of the 'set-point' was a revelation. It explains why our bodies fight so hard to maintain a certain weight regardless of willpower. While the author does have a bit of a thing for offal and animal fats, his argument against the modern food environment—specifically the damage done by sugar and industrial seed oils—is incredibly compelling. The writing is punchy, and the metaphors help simplify the heavy science of metabology. It really shifted my perspective on obesity from a moral failing to a biological signaling issue.

Picked this up after a recommendation and was floored by the depth of the metabolic science. The book successfully dismantles the 'calorie is a calorie' myth by showing how different nutrients actually communicate with our brains. Jenkinson's focus on 'Shit Life Syndrome'—the idea that stress, poor sleep, and a toxic food environment drive weight gain—is a refreshing take. I especially liked the sections on the Minnesota Starvation Experiment; it really clarifies why restrictive dieting leads to long-term metabolic damage. The prose is lively, though a bit repetitive in the middle sections. Regardless, the advice to cut out wheat and vegetable oils while embracing natural fats feels sustainable. It’s not a 'diet' book so much as an owner's manual for the human body.

Finally, a book that looks at obesity as a biological dysfunction rather than a character flaw! Jenkinson’s breakdown of the feedback loops between the gut and the brain is masterful. He explains why we feel hungry even when we have plenty of stored energy, blaming the hormonal 'noise' created by modern manufacturing. The way he describes insulin's role in fat storage helped me understand why my previous attempts at weight loss failed. It’s a very persuasive argument that focuses on food quality over quantity. Some might find the science heavy, but I appreciated that he didn't talk down to the reader. It’s an empowering read that puts the power back in the consumer's hands by exposing the tricks of the food industry.

Wow. I never thought I'd find a book about nutrition that I couldn't put down, but here we are. Jenkinson’s writing is engaging, and he uses brilliant metaphors to explain how our metabolism adapts to different environments. The 'thermostat' analogy for our body weight is perfect. He doesn't just tell you what to eat; he tells you *why* your body reacts the way it does to sugar and wheat. I’ve read a lot of health books, but this is the first one that made me realize why counting calories is a losing game. It’s a compassionate, evidence-based look at why we are facing an obesity epidemic. Highly recommended for anyone who is tired of the yo-yo dieting cycle.

After hearing so much conflicting advice over the years, Jenkinson’s breakdown of ghrelin and leptin felt like a lightbulb moment. This isn't your typical beach-body diet book; it's a deep dive into evolutionary biology and modern endocrinology. The author makes a very strong case for returning to ancestral eating patterns—more saturated fats and less processed junk. I loved the practical tips on rebalancing omega ratios, even if I’m not quite ready to start eating heart and liver for breakfast. The tone is mostly encouraging, though he doesn't pull any punches when criticizing the government's outdated nutritional guidelines. It’s a bit long in places, but the information is too important to skip. This should be required reading for anyone in the healthcare industry.

As someone who has struggled with weight for years, I found Jenkinson's explanation of the set-point theory incredibly liberating. He treats obesity with a level of compassion rarely seen in medical literature, acknowledging that 'willpower' isn't the magic bullet we’ve been told it is. The breakdown of how processed foods mess up our internal signals is fascinating, particularly the section on the omega-3 to omega-6 ratio. To be fair, I did find some of his historical anecdotes a bit dodgy—like the claim about Victorian women wanting blackened teeth as a status symbol. That felt a few centuries off! However, the core nutritional advice is solid. If you can get past some of the slightly cringey analogies, there’s a wealth of life-changing information here about how our environment triggers our genes.

Not what I expected from a weight loss book, but it’s probably the most scientific one I’ve read lately. The author is a bariatric surgeon, and his expertise shines through when he discusses the causal chains of biology. I was particularly struck by the argument regarding walnuts and the omega ratios—it’s detailed enough to satisfy a science nerd but explained well enough for a layman. My only real gripe is that he’s very dismissive of plant-based diets and seems to have a vendetta against grains that isn't always fully backed by broader research. He also makes some weird claims about the Venus of Willendorf that felt like a reach. Still, the core message about ultra-processed food is undeniable. It’s a dense read but worth the effort for the metabolic insights alone.

Frankly, I was skeptical about a surgeon telling me to eat more butter, but the logic here holds up surprisingly well. The book does a fantastic job of explaining how our modern diet of refined carbs and seed oils has essentially 'broken' our internal thermostats. I found the advice on mindful eating and managing cortisol through sleep and breathing very practical. However, the author’s obsession with the diet of the Inuit and Maasai felt a bit one-dimensional. Those are extreme environments, and it's hard to translate that directly to a modern urban lifestyle. I also wish there was more nuance regarding different types of grains rather than just a blanket ban on everything. That said, I've implemented some of the changes and already feel less 'food-obsessed' than I did on low-fat diets.

Ever wonder why every diet works for two months and then fails spectacularly? Jenkinson answers that question with a deep dive into metabolism, but I finished the book with very mixed feelings. On one hand, the science behind insulin and glucose spikes is brilliant and easy to follow. On the other hand, the author’s tone can be quite condescending toward people who can't afford his recommended lifestyle. Not everyone can spend their weekends sourcing grass-fed beef and fresh offal from a local butcher. There’s a certain level of privilege required to follow his 'simple' advice, and he glosses over the reality of food deserts and poverty. It's a great scientific resource, but the social commentary felt out of touch and occasionally mean-spirited toward the very people he claims to be helping.

The section on human evolution and history really undermined the author's credibility for me. Jenkinson claims humans descended from chimpanzees, which is a basic biological error; we share a common ancestor, but we aren't 'descended' from them. This kind of sloppiness makes me question the rest of his scientific claims. He also presents the Venus of Willendorf as a literal representation of a real person rather than a symbolic fertility goddess. Beyond the historical errors, the writing is often arrogant. He presents his theories as absolute facts while ignoring any evidence that contradicts his pro-meat, anti-grain stance. While the chapters on hormones are interesting, there are much better, more rigorously edited books on this topic—like Nadja Hermann’s work—that don't rely on oversimplified evolutionary myths to make a point.
