This 2-year randomized controlled trial assessed the effects of low-carbohydrate (LCD) and low-fat diets (LFD) on food cravings, preferences, and appetite among obese adults (LCD: n=134; LFD: n=136). The LCD group experienced greater reductions in cravings for carbohydrates/starches and preferences for high-carbohydrate and high-sugar foods, along with decreased hunger levels.
