We all know that fish is a healthy food. It is high in protein, low in calories and high in omega-3 fatty acids, which are great for our heart health. However, not all fish are created equal when it comes to weight loss. According to nutritionists, certain types of fish may actually promote belly fat. Here are six fish you should avoid if you’re trying to lose weight:

Atlantic salmon:

Atlantic salmon is a farmed fish that is excessively rich in omega-6s. It contains up to 1900 mg of omega-6s compared to farmed salmon which only has 114 mg. The calorie level of Atlantic salmon is around 200 calories per 100g. It is best to eat it steamed or raw with a squeeze of lemon to limit its caloric intake.

Doctors recommend including omega-3 fatty acids in our diets because they promote heart health and help reduce inflammation. However, too much omega-6 can have the opposite effect. By increasing inflammation and the risk of chronic diseases such as heart disease and obesity. This is why it is important to limit our consumption of omega-6 fatty acids, especially if our diet does not provide us with enough omega-3. While wild salmon is a good source of omega-3s, Atlantic salmon should be avoided due to its high omega-6 content.

Sardines :

Sardines are small fatty fish that are often canned and eaten as an inexpensive source of protein. Unfortunately, they are also one of the fish most likely to promote belly fat. Sardines are high in omega-3 fatty acids, which have been linked to increased belly fat. Additionally, sardines are also a good source of mercury, which can build up in the body and lead to weight gain. Mercury is a toxic metal that can damage the nervous system. It is particularly harmful to fetuses and young children. For these reasons, it is best to avoid consuming sardines regularly. If you eat them, be sure to cook them thoroughly to minimize the risk of exposure to mercury.

Mackerel :

Mackerel is a type of fish that has a high content of omega-3 fatty acids. It’s true that omega-3 fatty acids are essential for maintaining good heart health and preventing chronic disease. However, they can also promote the growth of belly fat. Omega-3 fatty acids help create new fat cells and also increase the amount of fat stored in existing cells. Also, omega-3 fatty acids make it difficult for the body to break down fat. Therefore, people who consume high amounts of omega-3 fatty acids are more likely to develop belly fat.

Breaded fish:

Fish is a healthier alternative to red meat. As it is recommended to eat it at least twice a week. However, it all depends on the type of cooking. Breaded fish is one type of fish that can actually cause belly fat. The breading contains simple carbohydrates which are quickly converted into sugar in the body. Also, breadcrumbs often contain trans fatty acids, which can lead to weight gain and increased belly fat. For these reasons, it’s best to avoid breaded fish when trying to maintain a healthy weight. Instead, favor fresh or frozen fish that has been baked or grilled, without any added calories.

The tilapia:

Tilapia is a fatty fish that promotes belly fat. It contains a high content of omega-6 fatty acids that stimulate inflammation. Inflammation of the intestines can lead to increased belly fat. Additionally, tilapia is usually fried in oil, which increases the amount of calories and fat. Omega-3 fatty acids can help reduce inflammation, so eat more fish like tuna, seafood, and herring. Fruits and vegetables are also rich in anti-oxidants and other nutrients that can help reduce inflammation. Eat a variety of healthy foods to maintain a flat stomach.


Although often considered a healthy option, swordfish can actually hurt your waistline. This type of fish has a high mercury content. This can lead to weight gain and an increased risk of heart disease. Additionally, swordfish is also a good source of omega-3 fatty acids. While these acids are important for maintaining heart health, they may also promote the growth of belly fat. Consumed in large amounts, omega-3 fatty acids can cause the body to store more fat in the abdominal area. For this reason, swordfish should be eaten in moderation to avoid promoting belly fat.
