Does Calcium Increase Fat Loss

Calcium Increases Fat Loss

PERTH, Australia—Starting the day with a breakfast full of calcium can help weight management by increasing fat oxidation rates and thermogenesis, and reducing spontaneous eating throughout the day, according to a new study published online in the journal of Clinical Nutrition (DOI:10.1016/j.clnu.2010.11.006).

Eleven overweight subjects, aged 54 (± 1.2 years) and with a body mass index (BMI) of 31 (± 2.4), participated in a randomized within-subject, sequential meal study comparing a low-calcium breakfast to a high-calcium breakfast. Diet-induced thermogenesis, fat oxidation rates , serum leptin and subjective feelings of hunger/satiety were measured at fasting and hourly over 8 hours. Subjects were allowed to eat lunch at liberty.

Researchers Wendy Chan She Ping-Delfos and Mario Soaresa, both from the Curtin University of Technology, Perth, observed those who ate the higher calcium breakfast showed higher fat oxidation rates (P=0.02) and a significantly greater thermogenesis (P=0.01). Further, those with more calcium were able to wait longer to eat dinner after the buffet (P=0. 083) and ate significantly fewer calories (P=0.017) in the following 24-hour period. Serum leptin changes following the higher calcium meal, but not lower calcium meal, was negatively related to 24-hour fat intake (P=0.016).
