Fox nuts or makhanas contain all the essential nutrients like potassium, iron, calcium, protein and magnesium, which are necessary for weight loss and gaining muscle mass. What makes makhanas a popular choice of snacks is its low-calorie content. 50 grams of dry-roasted makhanas have 180 calories and no saturated fat. Besides, they also contain a flavonoid called kaempferol, which has anti-inflammatory and anti-ageing properties. The tree nuts can help to control your cravings and keep you fuller between your meals. They are not only good for weight watchers but are also beneficial for people dealing with heart problems, insomnia, infertility issues and diabetes.
