5 Fatty Fish Rich in Omega-3 That Help Reduce Visceral Fat — Good for He.art Health and Body Shape

Fatty fish are not only good for heart health but also serve as a natural “weapon” to effectively reduce visceral fat. According to Herbalife USA, fish such as salmon, mackerel, tuna, sardines, and herring are rich in omega-3 fatty acids — nutrients known for their anti-inflammatory properties, ability to improve insulin resistance, and support in controlling fat accumulation in the abdominal cavity.

Incorporating fatty fish into your daily diet is a natural way to help reduce visceral fat, thanks to their abundant omega-3 fatty acids with strong anti-inflammatory effects.

Below are five types of fatty fish you should eat regularly to improve overall health and manage internal fat accumulation.

1. Salmon
As one of the best foods for health, salmon provides a high amount of omega-3 fatty acids — potent anti-inflammatory nutrients that help regulate insulin and effectively burn visceral fat.

A study published in the Journal of Nutrition found that eating salmon twice a week could help reduce visceral fat by 10–15% after 12 weeks. In addition to omega-3, salmon is also rich in high-quality protein and vitamin D, contributing to sustainable weight loss and the maintenance of lean muscle mass.

2. Mackerel
Mackerel ranks among the fish with the highest omega-3 content, around 2.6g per 100g of fish.

According to the American Heart Association (AHA), mackerel not only improves cardiovascular health by lowering bad cholesterol (LDL) and increasing good cholesterol (HDL) but also helps reduce visceral fat accumulation effectively. Eating mackerel 1–2 times a week can bring noticeable benefits for those managing their weight.

3. Sardines
Despite their small size, sardines are a “nutrient powerhouse” loaded with omega-3, calcium, and vitamin B12.

A study in the Journal of Lipid Research showed that omega-3 from sardines helps reduce visceral fat buildup and improve metabolic health. Additionally, sardines have lower mercury levels than many larger fish, making them safe for regular consumption.

4. Herring
Herring is a rich source of omega-3, vitamin D, and selenium — all essential micronutrients for metabolic and hormonal health.

According to the European Journal of Clinical Nutrition, herring not only reduces visceral fat but also helps lower cortisol levels — a hormone that, when elevated for long periods, can contribute to belly fat accumulation.

You can enjoy herring steamed, grilled, or in salads to preserve its nutritional value.

5. Tuna
A nutrient-dense option, tuna provides abundant protein and omega-3 fatty acids — two key factors that boost metabolism and help burn visceral fat.

According to the U.S. National Institutes of Health (NIH), eating tuna at least three times a week can help lower the risk of chronic inflammation and significantly improve heart function. For busy individuals, canned tuna in water is a convenient choice that can be easily paired with salads, whole-grain bread, or brown rice while still ensuring adequate nutrition.

Key Benefits of Omega-3 in Fatty Fish
Research from the Harvard T.H. Chan School of Public Health shows that omega-3 not only fights inflammation but also enhances insulin sensitivity, improves fat metabolism, and effectively reduces visceral fat. Additionally, omega-3 offers other benefits such as lowering heart disease risk, supporting brain health, and boosting mood.

A Few Tips for Adding Fatty Fish to Your Diet

• Control portions: 2–3 servings of fatty fish per week, around 150–200g per serving, is ideal.

• Choose low-mercury fish: Prioritize small fish like sardines and herring. Limit intake of large fish such as albacore tuna or swordfish.

• Combine with a healthy diet: For better visceral fat reduction, limit processed foods, refined sugar, and white starches.
