Rats fed a high-fat diet gained less weight and less body fat when lactose (milk sugar) was added to their diet according to a new study from researchers at Japan Women's University in Tokyo. Bone Density
Bone density higher in rats given lactose
They also found that bone density was higher in the rats given lactose, and, surprisingly, found that levels of vitamin D3 were 74 percent lower than in rats on a high-fat diet alone.
Comment: Lactose might be another factor in milk besides the calcium that has an effect on weight
Although far from conclusive, some studies on humans have suggested that calcium from milk might help to prevent weight gain or possibly increase weight loss. (I am skeptical about any claims that milk or calcium can cause weight loss, however, I believe that it might help to prevent weight gain.)
This study suggests that the lactose in milk might also be a factor.
