Protein Panic: How Much Do You Really Need? Everywhere you look, protein has become a competition. Scroll long enough and you will believe muscle disappears if you eat less than 150 grams a day. Meanwhile, influencers debate leucine thresholds like they’re trading baseball cards. As a result, ordinary meals now feel like math problems. However, biology does not require panic. Protein matters. Yet adequacy differs from excess. And importantly, most people eating real food already meet their needs. So let’s slow down.
First, What Protein Actually Does Protein builds and repairs tissue. In addition, amino acids support immune function and hormone signaling. Furthermore, specific amino acids such as leucine trigger muscle protein synthesis. Nevertheless, once you reach the effective leucine threshold in a meal, adding more protein does not multiply muscle growth. Instead, your body oxidizes the excess. Therefore, more does not always mean better.
How Much Is Enough? For most healthy adults, about 0.8 grams per kilogram of body weight covers basic needs. Meanwhile, adults over 60 often benefit from 1.0 to 1.2 grams per kilogram to protect lean mass. Notably, that recommendation does not require heroic intake. In fact, a 75–80 kilogram adult typically lands between 60 and 90 grams per day. Consequently, many people hit those numbers without even trying.
Here’s What I Actually Do I do not count protein. I never log grams. Moreover, I do not calculate leucine before breakfast. Instead, I eat normal meals. Most mornings, I have a shake. The recipe lives on terrysimpson.com. That shake provides roughly 25 grams of protein. Sometimes I add PB Fit. Occasionally, I include Greek yogurt. As a result, I increase protein slightly without thinking about it. Later, I eat three to five ounces of chicken breast with Louisiana hot sauce. That adds another 25 grams. Then at dinner, I often choose salmon and chickpeas. Together, they bring me to roughly 70–80 grams for the day. Importantly, I have lost 50 pounds and preserved muscle mass. I track muscle periodically. I see no decline. So what about leucine? High-quality animal protein contains about 8–10% leucine. Therefore, a 25-gram protein meal delivers about 2 grams of leucine. That amount typically triggers muscle protein synthesis. Thus, I hit the effective threshold at each meal without obsessing.
Now Let’s Bring In GLP-1 GLP-1 medications reduce appetite. Consequently, total intake drops. Because of that, protein intake can fall too. So yes, people using GLP-1 should pay attention. However, they do not need 180 grams per day. Instead, they need adequacy and resistance training. Lift something heavy. Spread protein across meals. Preserve lean mass. Simple.
Here’s the Real Deficiency Protein deficiency remains rare in the United States. By contrast, fiber deficiency remains common. According to the National Institutes of Health, most adults fail to meet recommended fiber intake levels. In fact, average intake falls far below the 25–38 grams per day recommended for adults. (Reference: NIH Office of Dietary Supplements – Fiber Fact Sheet) Meanwhile, high-protein diets often crowd out legumes, whole grains, and vegetables. So while people panic about protein, they quietly neglect fiber. And fiber feeds the microbiome. Fiber improves glycemic control. Fiber lowers LDL cholesterol. Protein builds muscle. Fiber protects metabolism. Both matter.
Mediterranean Patterns Keep It Balanced Mediterranean-style eating provides protein from fish, legumes, yogurt, and moderate poultry. At the same time, it supplies fiber from beans, vegetables, and whole grains. Therefore, protein arrives packaged with micronutrients and fermentable substrate. Unlike protein powders and bars, real food supports multiple systems at once. Consequently, longevity patterns emphasize diversity, not maximal single-nutrient intake.
The Takeaway Adequate protein preserves muscle. Resistance training drives adaptation. Fiber pr

With all the spices we have access to, it is amazing how bland recipes have become. I have many cookbooks, some from great chefs, television personalities, and friends. What I am always surprised by is how bland the food has become. People seem to think a bit of salt, pepper, maybe onions, and garlic provide the spices one needs. Perhaps it is because some associate spice with heat. Mostly because many have never experimented with some of those great warm spices available. A pinch of coriander, some freshly ground cumin, a little cardamom, or a touch of cinnamon can turn an ordinary dish into something remarkable. And the most astonishing part is that these spices financed voyages around the world, built cities, created fortunes, and caused people to kill one another. Without the spice trade, it is safe to say that the United States, as we know it, would be vastly different from what it is now. The money loaned to the United States, when we were a fledgling country, came from the wealthy spice merchants from what was considered one of the great hyperempires of the world, based in Amsterdam. But before we go to the birth of the United States, let me take you to the meatball.
Tea: The Drink That Built an Empire—and Helped Break One China had the tea. Britain had the appetite. John Hancock had a business to protect.
MesoAmerica and Chocolate In our series looking at foods that built civilizations, today we are going to stay in the Americas with chocolate. Chocolate has been used as currency, consumed by kings, incorporated into religious ceremonies, and prescribed as medicine. Today, it is a multibillion-dollar industry that wants you to believe that eating chocolate is an act of preventive cardiology. I mean, why not? They convinced us to give chocolate to people we love, eat it when we are happy, when we are sad, when only the dog understands us. Don’t feed chocolate to your dog. And we have done all this with a bitter seed that most of us would probably spit out if we tasted it straight from the tree.
I’ve been doing a series about foods that built civilizations. In this episode, we are talking about the potato. It is difficult to imagine that thousands of years ago, people constructed large buildings, managed rivers, built monuments, and created art. We have glimpses of these civilizations through stories, archaeology, and the structures they left behind, but much of their history has been lost. Imagine, we don’t even know where Cleopatra or Alexander the Great are buried, yet we know their stories. As European powers conquered Indigenous peoples, their languages, cultures, and oral traditions were suppressed. When a language disappears, so are the stories preserved within it. Our clues come from archaeology when we uncover a monument, a building, or an ancient settlement. In the Andes, the potatoes they cultivated were not the Russets, Yukon Golds, or fingerlings you find in the store today. Different colors, shapes, and textures. Adapted to survive the elevations, temperatures, and growing conditions. Biodiversity protected their food supply against frost, disease, and changing environmental conditions. If one variety failed, another might survive. The ancient wisdom of diversity that Andean farmers developed over thousands of years was lost when the potato eventually reached Ireland.
In our series about foods that built civilization, we talked a lot about grains, from wheat to corn to rice. Today, we are taking you to the ocean, with the civilizations that salmon built. From California to the interior of Alaska, salmon, a staple, allowed people to settle into villages, develop complex social networks, art, and trade routes. Those trade routes are as large as the ones in the Mediterranean. Some tribes built communal homes and developed complex art and language. Some were Seafaring tribes with canoes up to 60 feet long that traveled across oceans. All because there was a fish that would return in large numbers to streams and rivers, reliably, predictably. So predictable, the people could build their lives around salmon runs. So much so that some built a calendar not only with lunar cycles, but also with the return of the salmon. Civilizations have always gathered around food and water. The Mediterranean connected people who grew wheat and olives, giving people time to make wine, mine copper, build ships, trade with their neighbors, and occasionally go to war with them. Asia had rice and grain near the great river systems. The reliable calories from rice and grains allowed villages to become cities and to travel by water to trade. Today we are going to my home, from the Ventura River in California to my home state of Alaska.
