So, can you lose weight eating tuna?

While embarking on a weight loss journey often involves navigating through various dietary nutrition, tuna stands out as a favorable choice. As long as you choose the right type, you can include it when trying to lose weight. Our tuna fish are a moderate source of calories, making them an appropriate food to include in a weight-loss diet. 

However, when incorporating tuna into your diet, you should prioritize light tuna packed in water instead of olive oil. While there are a number of reasons why you should eat tuna, here’s how it can help you lose weight:

Burn fat

Tuna’s role in weight loss can be attributed to its abundance of polyunsaturated fatty acids, particularly omega-3 fatty acids. These fatty acids are not only known for their various health benefits, but also for their ability to regulate the metabolism and increase the rate of fat oxidation. Therefore, omega-3 fatty acids contribute to assisting the body in breaking down and utilizing fat stores, which ultimately results in burning fat.

By incorporating tuna into your diet, you may lose body fat all without compromising on taste. Generally, the results from regular consumption of tuna can be seen as soon as 12 weeks or more.

In addition to the fatty acids, another factor influencing weight loss with tuna is its rich protein content. Protein stands out as a crucial nutrient, helping the body burn calories more efficiently, as it has higher thermogenesis properties than carbs and fat. With tuna distinguishing itself as an extremely lean protein source, incorporating this fish into your diet can lead to an effective and sustainable approach toward losing excess body fat.

Maintain muscle

Beyond its ability to burn calories, the significantly high protein content in tuna fish can contribute to building and maintaining muscle mass. 

Simultaneous weight loss and muscle maintenance is a delicate balance but crucial nonetheless. Protein serves as the building block for muscle, promoting muscle repair and growth.

By incorporating this fish into your diet, you can take advantage of the muscle-sparing properties of protein, among many other benefits. This component will not only help you burn fat but also benefit your muscle mass maintenance by tapping into the fat cells for energy rather than breaking down muscle tissue.

Maintain caloric consumption

A vital step toward achieving and sustaining a healthy body weight is gaining control over your daily caloric consumption. Consuming foods high in protein is able to increase your metabolic rate, which in turn keeps you full for longer periods of time.

This is because protein-rich food releases satiety-inducing hormones, leading to a decrease in food intake and caloric consumption. By promoting fullness and satiety over longer periods, you can prevent overeating and the storage of excess energy and fats, thus averting weight gain.

Additionally, protein contents require longer digestion when compared to carbs or fats, thus preventing overconsumption as you’d feel full.

So, by incorporating protein-rich foods into your diet, you can achieve food satisfaction, reduced carvings, and improved weight management.

Possible Downsides of Consuming Tuna

While tuna is considered to be an ideal source for a weight-loss journey, there are some potential risks and downsides that you must be aware of. Here are some considerations and precautions you should take before indulging in a tuna diet for weight loss:

  • Insufficient calories - A simple tuna diet does not provide enough calories for an average adult, as fresh tuna has no calories. This issue may lead to a calorie deficit, which may cause slower metabolism, inadequate nutrient intake, loss of muscle mass, and extreme hunger. Incorporating other calorie-rich food to achieve the ideal calorie intake is best to continue a tuna diet.
  • Mercury Poisoning - While tuna is considered a healthy meal, it contains heavy metal mercury that may pose some risks when overly consumed, like increasing the chances of mercury poisoning. This may result in harmful effects on your heart, kidneys, immune system, and nervous system. Limiting your intake to two servings each week is considered the ideal amount of fish intake.
  • Highly restrictive and short-term - Indulging in a diet consisting of only tuna fish can make long-term health benefits questionable. An only-tuna diet is highly restrictive and short-term, which is usually only meant to be followed for three days.
