What the Science Says

Calories In, Calories Out

Weight change is governed by the laws of physics: to lose weight, you must consume fewer calories than you expend. Dozens of tightly controlled studies show that when calories and protein are matched, the ratio of carbohydrates to fat makes little difference to weight loss. The calorie deficit itself is what matters most for the number on the scale.

The Perception Gap

Most people underestimate how much they eat—often by 20% to 50%. This is especially true for snacks, drinks, and foods eaten on the go. Gold-standard studies using doubly labelled water show that self-reported intake is almost always lower than actual intake, making it easy to miss a calorie surplus without realising it.

Tracking Drives Success

The most consistent predictor of weight loss success is how often you track your food and activity. Self-monitoring creates a feedback loop that connects your daily choices to your results. People who track regularly lose more weight and are more likely to keep it off—especially when using modern, easy-to-use tools.
