A group of researchers from Spain, Portugal, Iceland and the Netherlands several studies observed that when fish included in a weight reduction diet, promoted weight loss compared with diets where fish are not included. This despite the fact that the calorie intake is equal. It also appears that the more often you eat fish, the easier it is to lose weight. The reason for this may be an amino acid in fish protein.

Healthy weight loss with fish
Both fatty and lean fish can make it easier to lose weight, so that both cod and salmon can be part of a reduced calorie diet.

In one study (Ramel et al., 2009) showed both species that they promote weight loss compared with the group not receiving seafood at all. Men who ate cod, salmon or fish oil decreased from 6.5 to 7.0 kg over eight weeks. The special feature of this study is that it suggests that a diet with lean fish with low omega-3 and high in fish protein gives the same weight loss as a diet rich in fish protein and / or omega-3 fatty acids.

The study ran over eight weeks and included 324 overweight men and women between 20 and 40 years. Group 1 (control group) received only capsules with sunflower oil instead of seafood, Group 2 ate 150 g cod three times a week, group 3 ate 150 g salmon three times a week and group 4 took fish oil capsules and ate no seafood. By the way the calorie intake was equally among the participants.

Only men who were given fish or fish oil had significantly more weight loss than those in the control group. There was no difference in weight loss among the female participants. This may be due to natural differences between men and women and that the absolute caloric intake was less for women.

The more you eat cod, the better it is
It may appear that there is a correlation between how much and often you eat fish and how much you lose weight. According to another study (Thorsdottir et al., 2007), would you have more weight loss if you eat fish five times a week, compared with if you “only” eat fish three times a week. It is simply a linear relationship between the amount of cod that were eaten and weight reduction, or a “dose-response relationship” as scientists call it.

In this study, 126 obese participants (20-40 years, BMI 27.5 to 32.5) followed over eight weeks while they ate a reduced calorie diet. Group 1 (control group) received no cod (nor seafood), Group 2 ate 150 grams of cod three times a week and group 3 ate 150 grams of cod five times a week. Group 2 was more weight (0.7 kg) than the control group, while group 3 decreased 1.7 kg more than the control group. Group 3 was also the most in BMI and waist circumference. In this study underwent both men and women equally weight.

Why fish can be beneficial for weight reduction?
The reason for the enhanced weight loss when the fish are included in the diet attributed either omega-3 fatty acids or proteins in general, although in a study as well as improved weight reduction by fish oil capsules alone.

The researchers discuss about weight loss as a result of fish intake may be associated with improved satiety from fish protein and especially because fish, such as cod, is especially rich in an amino acid called taurine. Taurine has been shown in several animal and human experimental studies to promote weight loss without having to know the reason for this. More research is needed before we know this for sure!

Fish is healthy, and fatty fish is communicated as extra healthy because of the omega-3 content. That’s right, but it is also good to vary with lean fish. Both are nutritious foods and lean fish are richer in iodine than oily fish. The protein in fish is easily digestible and has high quality.

The 20 Best Foods To Eat If You’re Trying To Lose Weight

Not all calories are created equal.

Different foods go through different metabolic pathways in the body.

They can have vastly different effects on hunger, hormones, and how many calories we burn.

Here are the 20 most weight-loss friendly foods on earth, supported by science.

1. Whole Eggs

Ralph Orlowski/Getty Images Once feared for being high in cholesterol, whole eggs have been making a comeback. New studies show that they don’t adversely affect blood cholesterol and don’t cause heart attacks (12).

What’s more … they are among the best foods you can eat if you need to lose weight. They’re high in protein, healthy fats, and can make you feel full with a very low number of calories.

One study of 30 overweight women showed that eating eggs for breakfast, instead of bagels, increased satiety and made them eat less for the next 36 hours (3). Another eight-week study found that eggs for breakfast increased weight loss on a calorie-restricted diet compared with bagels (4).

Eggs are also incredibly nutrient dense and can help you get all the nutrients you need on a calorie restricted diet. Almost all the nutrients are found in the yolks.

2. Leafy Greens

Flickr/laurelfan Leafy greens include kale, spinach, collards, swiss chards, and a few others. They have several properties that make them perfect for a weight-loss diet.

They are low in both calories and carbohydrates, but loaded with fiber. Eating leafy greens is a great way to increase the volume of your meals without increasing the calories. Numerous studies show that meals and diets with a low energy density make people eat fewer calories overall (5).

Leafy greens are also incredibly nutritious and very high in all sorts of vitamins, minerals, and antioxidants. This includes calcium, which has been shown to aid fat burning in some studies (6).

3. Salmon

Flickr/James Bowe Oily fish like salmon are incredibly healthy. They are also very satisfying, keeping you full for many hours with relatively few calories.

Salmon is loaded with high-quality protein and healthy fats and also contains all sorts of important nutrients. Fish, and seafood in general, supply a significant amount of iodine.

This nutrient is necessary for proper function of the thyroid, which is important to keep the metabolism running optimally (7). Studies show that a huge number of people in the world aren’t getting all the iodine they need (8).

Salmon is also loaded with Omega-3 fatty acids, which have been shown to help reduce inflammation, which is known to play a major role in obesity and metabolic disease (9, 10).

Mackerel, trout, sardines, herring, and other types of oily fish are also excellent.

4. Cruciferous Vegetables

Flickr Cruciferous vegetables include broccoli, cauliflower, cabbage, and brussels sprouts. Like other vegetables, they are high in fiber and tend to be incredibly fulfilling.

What’s more … these types of veggies also tend to contain decent amounts of protein. They’re not as high in protein as animal foods or legumes, but they’re high compared with most vegetables.

A combination of protein, fiber, and low energy density makes cruciferous vegetables the perfect foods to include in your meals if you need to lose weight. They are also highly nutritious and contain cancer-fighting substances (11).

5. Lean Beef and Chicken Breast

Flickr/avlxyz Meat has been unfairly demonized. It has been blamed for all sorts of health problems, despite no good evidence to back it up.

Although processed meat is unhealthy, studies show that unprocessed red meat does NOT raise the risk of heart disease or diabetes (12, 13). According to two big review studies, red meat has only a very weak correlation with cancer in men and no correlation at all in women (14, 15).

The truth is … meat is a weight-loss friendly food because it’s high in protein. Protein is the most fulfilling nutrient, by far, and eating a high-protein diet can make you burn up to 80 to 100 more calories per day (16, 17, 18).

Studies have shown that increasing your protein intake to 25% to 30% of calories can cut cravings by 60%, reduce desire for late-night snacking by half, and cause weight loss of almost a pound per week — just by adding protein to the diet (19, 20).

If you’re on a low-carb diet, then feel free to eat fatty meats. But if you’re on a moderate- to high-carbohydrate diet, then choosing lean meats may be more appropriate.

6. Boiled Potatoes

Flickr/philgradwell White potatoes seem to have fallen out of favor for some reason. However, they have several properties that make them a perfect food, both for weight loss and optimal health.

They contain an incredibly diverse range of nutrients, a little bit of almost everything we need. There have even been accounts of people living on nothing but potatoes for extended periods of time.

They are particularly high in potassium, a nutrient that most people don’t get enough of and plays an important role in controlling blood pressure. On a scale called the Satiety Index, that measures how fulfilling different foods are, white, boiled potatoes scored the highest of all the foods tested (21).

What this means is that by eating white, boiled potatoes, you will naturally feel full and eat less of other foods. If you boil the potatoes, then allow them to cool for a while, then they will form large amounts of resistant starch, a fiber-like substance that has been shown to have all sorts of health benefits — including weight loss (22).

Sweet potatoes, turnips, and other root vegetables are also excellent.

7. Tuna

Flickr/sashafatcat Tuna is another low-calorie, high-protein food. It is lean fish, so there isn’t much fat in it.

Tuna is popular among bodybuilders and fitness models who are on a cut because it’s a great way to keep protein high, with total calories and fat low.

If you’re trying to emphasize protein intake, then make sure to choose tuna canned in water, not oil.

8. Beans and Legumes

Flickr/kake_pugh Some beans and legumes can be beneficial for weight loss. This includes lentils, black beans, kidney beans, and some others.

These foods tend to be high in protein and fiber, which are two nutrients that have been shown to lead to satiety. They also tend to contain some resistant starch.

The main problem is that a lot of people have problem tolerating legumes. For this reason, it is important to prepare them properly.

9. Soups

Katka Lapelosa As mentioned above, meals and diets with a low energy density tend to make people eat fewer calories. Most foods with a low energy density are those that contain lots of water, like vegetables and fruits.

But you can also just add water to your food by making a soup.

Some studies have shown that eating the exact same food, except made in a soup instead of as solid food, makes people feel more satiated and eat significantly fewer calories (23, 24).

10. Cottage Cheese

Wikimedia Commons Dairy products tend to be high in protein. One of the best ones is cottage cheese — calorie for calorie, it is mostly just protein with very little carbohydrates and fat.

Eating plenty of cottage cheese is a great way to boost your protein intake. It is also very satiating, making you feel full with a relatively low number of calories.

Dairy products are also high in calcium, which has been shown to aid in the fat-burning process (25).

11. Avocados

Flickr/cyclonebill Avocados are a unique type of fruit. Whereas most fruit is high in carbs, avocados are loaded with healthy fats.

They are particularly high in monounsaturated oleic acid, the same type of fat found in olive oil. Despite being mostly fat, they also contain a lot of water, so they aren’t as energy dense as you may think.

Avocados are perfect as additions to salad, because studies show that the fats in them can increase the nutrient uptake from the vegetables 2.6 to 15-fold (25). They also contain many important nutrients, including fiber and potassium.

12. Apple Cider Vinegar

Flickr/shockinglytasty Apple cider vinegar is incredibly popular in the natural health community. It is popular for use in condiments, like dressings or vinaigrettes. Some people even dilute it in water and drink it.

Several studies in humans suggest that vinegar can be useful for people who are trying to lose weight. Taking vinegar at the same time as a high-carb meal can increase feelings of fullness and make people eat 200 to 275 fewer calories for the rest of the day (26, 27).

One study in obese individuals also showed that 15 or 30 mL of vinegar per day for 12 weeks caused weight loss of 2.6 to 3.7 pounds, or 1.2 to 1.7 kilograms (28). Vinegar has also been shown to reduce blood-sugar spikes after meals, which may lead to all sorts of beneficial effects on health in the long term (29, 30).

13. Nuts

Wikimedia Commons Despite being high in fat, nuts are not inherently fattening. They’re an excellent snack, containing balanced amounts of protein, fiber, and healthy fats.

Studies have shown that eating nuts can improve metabolic health and even cause weight loss (31, 32). Population studies have also shown that people who eat nuts tend to be healthier, and leaner, than the people who don’t (33).

Just make sure not to go overboard, as they are still pretty high in calories. If you tend to binge and eat massive amounts of nuts, then it may be best to avoid them.

14. Some Whole Grains

Wikimedia Commons Despite grains having gotten a bad rap in recent years, some types are definitely healthy. This includes some non-gluten, whole grains that are loaded with fiber and contain a decent amount of protein as well.

Notable examples include oats, brown rice, and quinoa. Oats are loaded with beta-glucans, soluble fibers that have been shown to increase satiety and improve metabolic health (34, 35).

Rice, both brown and white, can also contain significant amounts of resistant starch, especially if cooked and then allowed to cool afterward (36). Keep in mind that refined grains are a disaster, and sometimes foods that have “whole grains” on the label are highly processed junk foods that are both harmful and fattening.

If you’re on a very low-carb diet, then you’ll want to avoid grains, because they are high in carbohydrates. But there’s nothing wrong with eating some of the healthier grains if you can tolerate them and are not on a low-carb diet.

15. Chili Pepper

Flickr/amusedeyes Eating chili peppers may be useful on a weight-loss diet. They contain a substance called capsaicin, which has been shown to help reduce appetite and increase fat burning in some studies (37, 38, 39).

This substance is even sold in supplement form and is a common ingredient in many commercial weight-loss supplements. One study showed that eating one gram of red chili pepper reduced appetite and increased fat burning in people who didn’t regularly eat peppers (40).

However, there was no effect in people who were accustomed to eating spicy food, indicating that some sort of tolerance can build up.

16. Fruit

Wikimedia Commons Most health experts agree that fruit is healthy. Numerous population studies have shown that people who eat the most fruit (and vegetables) tend to be healthier than people who don’t (41, 42).

Of course, correlation does not equal causation, so those studies don’t prove anything, but fruit does have properties that make it weight-loss friendly. Even though fruits contain sugar, they have a low energy density and take a while to chew. Plus, the fiber helps prevent the sugar from being released too quickly into the bloodstream.

The only people who may want to avoid or minimize fruit are those who are on a very low-carb, ketogenic diet, or have some sort of intolerance to fructose.

For the rest of us, fruits can be an effective (and delicious) addition to a weight-loss diet.

17. Grapefruit

Flickr/calliope One fruit that deserves to be highlighted is grapefruit, because its effects on weight control have been studied directly. In a study of 91 obese individuals, eating half a fresh grapefruit before meals caused weight loss of 3 1/2 pounds (1.6 kg) over a period of 12 weeks (43).

The grapefruit group also had reductions in insulin resistance, a metabolic abnormality that is implicated in various chronic diseases.

So, eating half a grapefruit about a half hour before some of your daily meals may help you feel more satiated and eat fewer overall calories.

18. Chia Seeds

Flickr/ljguitar Chia seeds are among the most nutritious foods on the planet. They do contain 12 grams of carbohydrates per ounce, which is pretty high, but 11 of those grams are fiber.

This makes chia seeds a low-carb-friendly food, and one of the best sources of fiber in the world (44). Because of all the fiber, chia seeds can absorb up to 11 to 12 times their weight in water, turning gel-like and expanding in your stomach (45).

Although some studies have shown that chia seeds can help reduce appetite, they have not found a statistically significant effect on weight loss (46, 47). However, given their nutrient composition, it makes sense that chia seeds could be a useful part of a weight-loss diet.

19. Coconut Oil

Flickr/verymom Not all fats are created equal. Coconut oil is high in fatty acids of a medium length, called Medium Chain Triglycerides (MCTs).

These fatty acids have been shown to boost satiety compared with other fats, as well as increase the number of calories burned (48, 49). There are also two studies, one in women and the other in men, showing that coconut oil led to reduced amounts of belly fat (50, 51).

Of course, coconut oil still contains calories, so adding it on top of what you’re already eating is a bad idea. So this is not about adding coconut oil to your diet, it is about replacing some of your other cooking fats with coconut oil.

Extra virgin olive oil is also worth mentioning here, because it is probably the healthiest fat on the planet.

20. Full-fat Yogurt

Flickr/backpackfoodie Another excellent dairy food is yogurt. Yogurt contains probiotic bacteria that can improve the function of your gut.

Having a healthy gut may potentially help protect against inflammation and leptin resistance, which is the main hormonal driver of obesity. Just make sure to choose full-fat yogurt — studies show that full-fat dairy, but not low-fat, is associated with a reduced risk of obesity and type 2 diabetes over time (52).

Low-fat yogurt is usually loaded with sugar, so it is best to avoid that stuff like the plague.

28-day meal plan

Seafish has teamed up with registered dietician and nutritionist Juliette Kellow to put together a 4-week menu that shows you just how simple– and tasty – it is to add more fish to your diet.
