Brief summary
The aim of the project is to determine if milk supplementation during a caloric restriction program facilitates the lost of weight, improves the appetite control and attenuates the decrease of bone mineral content in low-calcium consumer women.
Detailed description
Calcium deficiency is related to a higher risk of obesity. Some studies showed a lost of weight by elevating the calcium consumption to reach the recommended level. Milk supplementation could be a good alternative to reach this objective, but its impact on weight loss and on appetite sensations has not been verified. Furthermore, losing weight leads to some negative consequences like a decrease of bone mineral content. Considering the benefits of milk on bone health, a higher intake of this food product during weight loss could represent a healthy strategy.
