Calorie-density

When losing weight, food choices should maximise satiety per calorie, preserve lean mass, and maintain nutritional adequacy. This article ranks food categories by satiety index, protein density, and calorie density — with practical meal-building guidance.

The right calorie intake for weight loss is TDEE minus 500–600 kcal (NICE recommendation). But where those calories come from — protein, carbohydrate, fat, fibre — affects hunger, lean mass retention, and adherence at the same total intake. This article covers calorie targets and composition.

Slimming World Syns are a flexible allowance system for higher-calorie foods within the Food Optimising plan. This article explains how Syn values are calculated, the nutritional science behind the system, common Syn values, and how to use the allowance effectively.

Food substitutions produce weight loss by reducing caloric density, increasing protein and fibre content, or improving satiety per calorie. This article applies evidence on energy density, satiety, and glycaemic response to quantify the most impactful substitutions with specific caloric saving and nutritional data.

The foods most associated with unintended overconsumption share specific characteristics: high energy density, low protein proportion, rapid oral processing, and engineered palatability. This article reviews the evidence on which food categories consistently drive excess calorie intake and why.
