Why Diets Fail (And How to Fix It)
By Dino Pohilj, Founder, RealFoods
If diets actually worked, the diet industry wouldn’t be a $70 billion business. It depends on repeat customers, and repeat customers exist because long-term follow-up studies have demonstrated that 80-95% of dieters regain most of the lost weight within five years. The problem isn’t the dieter; it’s the method.
The Cycle of Restriction
Most diets are built on extreme restriction, cut food groups, slash calories, eat in tiny windows. They work for about three weeks. Willpower is finite, and life eventually intervenes: a wedding, a stressful day, a slice of cake. The restrictive logic frames any deviation as failure, which produces the predictable binge-restrict loop.
Researchers have established that this cycle is not a character flaw. It is the body defending itself against perceived starvation through a measurable rise in ghrelin and a measurable fall in metabolic rate.

Building Sustainable Habits, Not Prisons
We argue permanent weight loss requires habits you can maintain on your worst day, not just your best one. That rules out streak mechanics, red-text guilt loops, and aggressive calorie ceilings, all features modern diet apps borrow from gambling psychology to drive engagement.
RealFoods removes those mechanics deliberately. Eat a meal that spikes blood sugar and the app does not yell. It records a Weight Impact Score of, say, 8 and offers a gentler suggestion for the next meal. The goal is awareness, not perfection, a metric you can lose on, learn from, and continue using.
The single most consistent finding in long-term weight-loss research is that adherence beats optimisation. The "best" diet is the one you will still be following in two years.
