The Portion Size Audit
Plate sizes have increased from 9 inches in the 1960s to 11-12 inches today—a 12-inch plate has 44% more surface area. Research by Geier, Rozin, and Doros on “unit bias” shows people serve themselves 25-30% more on larger plates without awareness, then eat it all because a full plate feels like a complete meal. You’re not choosing portions—your plates are. Smaller plates are one of the simplest environmental interventions. This companion covers the expanding plate, unit bias, visual illusions, the audit, and the intervention. (4 min read)
The Refrigerator Door
Door shelves are prime refrigerator real estate—maximum visibility, easiest reach, frequent exposure every time you open the door. Research by Hollands shows proximity dramatically affects consumption. What lives there shapes what you consume. Water, front and center, increases hydration. Easy-to-grab snacks are dangerous. This companion covers why door shelves matter, common inhabitants, conducting the audit, and strategic placement using accessibility to your advantage. (3 min read)
The Gardener
Gardens don’t happen overnight—they require daily attention and seasonal patience. Research by Clear shows small habits compound over time. Your health works the same way: consistent small actions create abundance. The gardener doesn’t starve plants to make them grow faster. They water daily, weed what doesn’t belong, prune excess, and protect from pests. This companion covers the gardening mindset, daily tending, seasonal patience, and building for the long term.

The Satiety System
Four qualities create lasting satisfaction without overconsumption: high protein, high fiber, high water content, and low caloric density. Research measuring 38 foods found boiled potatoes scored 323% on the satiety index while croissants scored just 47%. Fat, surprisingly, had a negative correlation with fullness per calorie. This companion explores the satiety index, the four factors that predict fullness, why this explains which eating patterns work, and how to choose foods that satisfy naturally. (4 min read)
The Cheat Day Concept
“Cheat days” can serve legitimate purposes—psychological relief, social flexibility, sustainability—or become license for extreme overeating that erases a week’s deficit in 24 hours. Research on restrained eating shows the approach matters more than the concept itself. Ask honestly: Does your cheat day leave you satisfied and ready to resume normal eating, or does it become a binge? The answer tells you whether it’s strategic or self-sabotage. This companion covers the case for and against, and better alternatives. (4 min read)
Protein and Insulin
Protein triggers insulin, but differently than carbohydrates—through direct amino acid stimulation, not blood sugar spikes. Research by Holt on the insulin index shows protein-rich foods stimulate significant insulin despite low carb content. Protein also triggers glucagon, which partially offsets insulin’s effects. Fat has minimal insulin impact. The result: protein causes a more moderate, balanced hormonal response supporting satiety and muscle preservation. This companion covers carbs and insulin, protein and insulin, fat and insulin, and practical implications for meal design. (3 min read)
Economic Choice
Your brain makes food decisions like an economist: weighing cost (effort, time) against expected reward. Research by Rangel shows the brain’s decision circuitry computes value based on effort and reward. Thaler and Sunstein’s work on “nudge” theory shows defaults drive choices. Lower cost + higher reward = more likely to choose. This is why convenient junk food wins. The solution: make healthy choices lower cost and unhealthy choices higher cost. This companion covers neural economics, why junk food wins, restructuring the equation, the environment lever, and defaults. (4 min read)
The Capable One
The capable one has the skills to eat well—and uses them. Research by Bandura shows self-efficacy strongly predicts success. Capability isn’t potential; it’s demonstrated competence. You know how to prepare healthy food, navigate restaurants, handle cravings. Today, capability looks like applying those skills—making good choices not because conditions are perfect, but because you’re competent to handle them. This companion covers capability versus aspiration, what it includes, and action today. (3 min read)
The Chocolate Stash
The hidden chocolate stash reveals your relationship with chocolate. High-percentage dark chocolate (70%+) is legitimately different from milk chocolate—less sugar, more bitter, harder to overeat. But even “healthy” dark chocolate stashed for emergencies becomes problematic if emergencies happen weekly. Hiding food often indicates ambivalence about consumption. The type matters, but the hiding and quantity matter more. This companion covers the audit, dark chocolate justifications, and honest assessment. (4 min read)
The Compensation Effect
Health halos create permission to eat more. Research by Schuldt shows people judged organic Oreos as lower-calorie than identical conventional ones—and felt more justified skipping exercise after eating them. When food is labeled healthy, organic, or low-fat, people unconsciously eat larger portions. “Healthy” choices often lead to consuming more total calories than straightforward indulgence. This companion covers the health halo effect, the research, why it happens, and practical implications for awareness. (3 min read)
