Objective: The influence of dairy product consumption on food intake and appetitive sensations was explored in a cross-over design study with individuals who were habitually low (<1 serving/d) or high (>3 servings/d) dairy consumers.
Research methods and procedures: Fifty-eight participants were required to eat one portion of dairy each day (low dairy) or three portions of dairy each day (high dairy) for 7 days. After a 7-day washout period, the opposite treatment condition was completed. Food intake and appetitive ratings were measured on each day of the treatment periods.
Results: During the high-dairy period, participants consumed 209 kcal/d more than during the low dairy period (p < 0.05). There were no significant differences in subjective appetite ratings. Habitual dairy use did not influence either the appetitive or dietary findings.
Discussion: These data indicate that increasing dairy consumption may lead to increased energy intake, which could potentially cause weight gain.
