Drinking milk can help increase weight loss, multiple studies find.
A glass or two of milk each day could increase weight loss by 100 percent, one study has found.
Milk can double fat loss in comparison to both soy milk and a carbohydrate drink, another study has found.
It is thought that both the vitamin D and calcium in milk may be beneficial for weight loss.
Around 50 percent of obese people have a calcium deficiency and half of the general population are deficient in vitamin D.
Now, a new study finds that children drinking whole-fat milk have a 40 percent reduced chance of being obese.
The researchers reviewed 29 separate studies carried out in seven countries, including almost 21,000 children.
Of these, 18 of the studies suggested that children drinking whole milk every day were less likely to be obese or overweight.
The findings are in contrast to many international guidelines that children should drink low-fat milk to avoid weight gain.
Dr Jonathon Maguire, study co-author, said:
“The majority of children in Canada and the United States consume cow’s milk on a daily basis and it is a major contributor of dietary fat for many children.
In our review, children following the current recommendation of switching to reduced-fat milk at age two were not leaner than those consuming whole milk.”
The next step in the research is to establish cause and effect, said Dr Maguire:
“All of the studies we examined were observational studies, meaning that we cannot be sure if whole milk caused the lower risk of overweight or obesity.
Whole milk may have been related to other factors which lowered the risk of overweight or obesity.
A randomized controlled trial would help to establish cause and effect but none were found in the literature.”
None of the studies reviewed suggested that drinking reduced fat milk decreased the risk of obesity or being overweight.
The study was published in The American Journal of Clinical Nutrition (Vanderhout et al., 2019).
