Females will be pleased to read that studies have shown those who drink skimmed milk each day in the 2 weeks leading up to their menstrual cycle suffer fewer cravings, related to hormones. Milk is also a superb source of protein, Vitamin D and Calcium – all of which help to aid muscle building. Larger muscles need more energy (calories) to function and therefore aids weight loss. Make sure you don’t opt for full-fat milk though. Non-fat, skimmed or low-fat are all good choices.
