Should You Add Prawns to Your Weight-Loss Diet?

Online Seafood Delivery Seafood seafood direct seafood home delivery

Prawns are exclusively found in freshwater and tend to be larger and meatier than regular shrimp. Prawns have gained popularity among health aficionados due to their numerous nutritional properties.

They are very high in omega-3s, which are good for the heart. They are also an excellent snack and can even be served as a main course when paired with boiled or stir-fried veggies. Prawns are high in protein and extremely low in calories, making them an excellent addition to any weight-loss diet.

Why buy king prawns?

Prawns are an excellent source of protein, vitamin B3, vitamin D, and zinc. They also contain no carbs, making them ideal for those trying to lose weight. High zinc levels are also helpful since zinc helps increase circulating leptin levels. Leptin is a hormone that is important in regulating the body’s energy homeostasis, fat storage and appetite. Low leptin levels often cause craving more calorie-dense foods and overeating.

Prawns also contain iodine, which aids in maintaining the basal metabolic rate (the rate at which the body burns calories at rest). Not getting enough iodine can cause underactive thyroid (or “hypothyroidism”), contributing to weight gain.

What are the nutritional benefits of prawns?

Calcium, potassium, vitamin A, vitamin E, and other essential nutrients can be found in prawns. Prawns also contain substantial amounts of vitamin B3, B6 and B12. They are also a good source of iron, which plays a vital role in haemoglobin production. Learn more about nutritional value of prawns for your body here.

Prawns are loaded with proteins.

Prawns are perhaps the most recommended food by nutritionists because they are high in protein. Per 100 grams of serving, prawns offer roughly 25 grams of protein. A high-protein diet helps in weight loss. Protein also boosts your body’s energy and takes a long time to digest, causing you to burn more calories and feel satiated for longer.

By keeping you full, it raises levels of appetite-reducing hormones, including Glucagon-like peptide 1 (“GLP-1”), Peptide YY (“PYY”), and Cholecystokinin (“CCK”) while decreasing levels of the hunger hormone, ghrelin. 

Prawns are low in fat and calories.

Prawns are a lean protein source, with only 0.3 grams of fat per 100 grams of serving. Prawns are high in unsaturated fats, which can benefit your general health. Prawns are a great low-fat food to add to your diet if you are trying to lose weight.

Prawns have a low-calorie count as well. Prawns contain only about 99 calories per 100 grams. Pair them with other low-calorie veggies, and you are good to go!

Prawns are rich in Omega-3s.

Prawns are also a great source of omega-3 fatty acids. These fatty acids, when consumed regularly, can help reduce chronic inflammation and body fat.
