Yes, you can get all necessary micronutrients in a time-restricted window, but it requires attention. Your needs don’t change: you’re just fitting them into fewer hours. Nutrient density becomes more important when eating opportunities are limited. Watch for calcium, vitamin D, iron, fiber, B12, potassium. This companion covers what you need, the challenge of time restriction, nutrients of concern, strategies, and when supplementation makes sense. (3 min read)

Dietary guidelines have shifted dramatically: from fearing fat to fearing sugar, from margarine to olive oil. Kearns’s analysis of internal industry documents shows one such episode: sugar-industry money behind a 1967 review that blamed fat. The experts were certain then too. Today’s certainty may be tomorrow’s revision. What stayed consistent: eat vegetables, limit processed food, whole grains over refined. This companion covers the major shifts, why they changed, and what this means for you. (3 min read)

The food matrix is the physical structure of whole foods: how fiber, fat, protein, and micronutrients are arranged together. Jacobs and Tapsell’s argument is that food, not the nutrient, is nutrition’s fundamental unit, because structure governs digestion and absorption. One experiment shows it as a gradient. Preloads matched for weight, calories, energy density, and eating rate produced a gradient in how much people ate afterward: whole apple 85% of control, applesauce 94%, juice about 99%. Adding fiber back to juice restored nothing, but that arm tasted worse too, so it cannot settle whether fiber is the missing piece. What tracks…

“Bliss point” names the idea that food products are tuned to the pleasure level that keeps you eating; that is a claim about industry practice rather than a measured finding. What is measured: three nutrient combinations that define hyper-palatable food, met by 62% of the foods in a US food database and by no fresh fruit, meat, or fish, and a trial in which people ate about 508 more calories a day of ultra-processed food without rating it more pleasant. This companion covers the definition, the trial, and what it means for you. (3 min read)

Many processed foods are industrial formulations, finished with cosmetic additives such as flavors, emulsifiers and sweeteners, and designed to be hyper-palatable, convenient and profitable. One paper defines hyper-palatable food by nutrient thresholds: 62% of the foods in a US database met them, and none of the fresh or raw fruits, meats or fish did. In a controlled trial, people ate 508 calories a day more on an ultra-processed diet without rating it any more pleasant. This companion covers what “hyper-palatable” means, how the products are made, and what this means for you. (2 min read)

Documents revealed in 2016 show the Sugar Research Foundation funded, and set the objective for, a 1967 Harvard review that blamed heart disease on fat rather than sugar, though that it shaped the conclusions is circumstantial. Research by Kearns brought those documents to light, and the 1980 Dietary Guidelines that followed focused on fat rather than sugar. Industry strategies: funding favorable research, attacking critics, creating doubt. Understanding this history explains confusing dietary advice and warrants skepticism toward industry-funded research. This companion covers the historical manipulation and modern implications.

The food industry’s goal is selling more food, not improving health, and these goals often conflict. The definition is measured: hyper-palatable combinations are quantitatively defined, and 62% of foods in a US food database meet the criteria. The most useful number for a shopper: 49% of items labeled “reduced” or “no” fat, sugar, salt, or calories still qualify as hyper-palatable. The wider claims about marketing budgets, research funding, and lobbying are a case two books in its further reading make, not settled findings. This companion covers the fundamental conflict, how the industry responds, and what it means for navigating the…

“Setpoint” is one model of what your body defends, and it is not settled: a competing settling-point model has weight simply coming to rest where environment and biology balance, and neither pure model is adequate alone. Speakman’s review, often cited for how a setpoint moves, is in fact the paper arguing that set points do not explain the data. Within that caveat: whatever is defended does not appear fixed for life. It drifts upward under modern conditions. What is proposed to bring it down (fasting, food quality, sleep, time at a lower weight) is proposed rather than demonstrated, and this…

By the usual US survey figures, obesity rates began rising sharply around 1980 after decades of stability. Several things changed in that window: high-fructose corn syrup, low-fat dietary guidelines, processed food, portion inflation, more frequent eating. This companion is careful about the difference between things that changed and things that caused it. Portion expansion parallels the curve; the 1980 guidelines did focus on fat rather than sugar. Neither is a demonstrated cause, and no single factor is claimed here. Human genetics didn’t change in forty years; the environment did, and which parts of it did the work is less settled…

The trillions of bacteria in your gut are not passive residents, and a developed proposal holds that they influence your cravings. Alcock and colleagues proposed, as a mechanism rather than a demonstration, that bacteria may generate cravings for the foods that feed them. On that account, changing what you eat would change your microbiome and, through it, what you crave. Dietary changes are often said to begin shifting bacterial populations within a day or two, though that timing is not independently sourced. This companion covers the gut-brain axis, how bacteria influence cravings, the research, and creating positive feedback loops. (4…
