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 isolates it cleanly: preloads matched for weight, calories, energy density, and eating rate, differing only in form, produced a gradient in how much people ate afterward — whole apple 85% of control, applesauce 94%, juice about 99%. And adding the fiber back to juice restored nothing. So it isn’t the fiber as a nutrient; it’s volume, chewing, and…

The bliss point is the precise combination of sugar, salt, and fat that maximizes pleasure without triggering fullness. Food scientists use mathematical models to find this exact formula for each product. “Vanishing caloric density” — foods that melt quickly — tricks your brain into thinking you have not eaten much. Difficulty stopping is not weakness; it is the product working as designed. This companion covers what the bliss point is, how it overrides satiety, examples, and what this means for you.

On Michael Moss’s reporting, the processed food industry engineers foods to maximize craveability, including a “bliss point” for sugar, the level that maximizes pleasure. “Vanishing caloric density” is said to leave your brain registering less than you ate, on reporting rather than measurement. Dynamic contrast (crispy and creamy) prevents sensory boredom. On that account, these aren’t accidents but design. This companion covers what “hyper-palatable” means, the key engineering techniques, and what this means for you. (3 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 exposed this manipulation that influenced dietary guidelines for decades. 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 engineering is measured, not alleged: hyper-palatable combinations are quantitatively defined and exceed ratios found in nature, 62% of foods in the US food system database meet the criteria, and the “bliss point” is a real per-product calculation — though for fat there is no bliss point, so it can be added without a ceiling. The most useful number for a shopper: 49% of items labeled low, reduced or no sugar, fat or sodium still qualify as hyper-palatable. The wider claims about marketing…

The setpoint isn’t permanently fixed — it can change in both directions. Research by Speakman shows it drifts upward through chronic processed food consumption, constant eating, and poor sleep. It can be lowered through fasting, reduced insulin exposure, improved food quality, and time at a lower weight. The goal isn’t to overpower your body’s regulation system forever — it’s to change what your body defends. This companion covers what raises the setpoint, what lowers it, and practical implications.

Around 1980, obesity rates began rising sharply after decades of stability. Research by Cutler documents multiple converging changes: high-fructose corn syrup, low-fat dietary guidelines (increasing carbs), processed food explosion, portion inflation, increased eating frequency. Human genetics didn’t change — the environment did. No single factor caused the epidemic; the combination created an obesogenic environment our bodies weren’t designed for. This companion covers the timeline and what changed. (3 min read)

The trillions of bacteria in your gut actively influence cravings, hunger, and fat storage. Research by Alcock shows different bacteria request their preferred fuel — sugar-loving bacteria drive sugar cravings. Changing what you eat changes your microbiome, which changes what you crave. Dietary changes begin shifting bacterial populations within 24-48 hours. This companion covers the gut-brain axis, how bacteria influence cravings, the research, and creating positive feedback loops.
