Some vitamins and minerals can also help you lose weight by acting as natural appetite regulators and/or by stimulating your body’s metabolism of fat. Obtaining the right levels of these nutrients is essential to any weight loss program. Studies show that eating zinc-rich foods raise levels of the hormone leptin in the blood. High leptin levels are associated with weight loss and reduced appetite. Research shows that zinc deficiency leads to low leptin levels and a preference for fatty foods, leading to weight gain. Increase zinc-rich foods like extra-lean meat, oysters, whole-grain breads, or cooked rajma and chickpeas. Also make bajra, ragi, jowar or multi-millet rotis and barley khichdi a part of your meals regularly to lose weight.
