Tuna diet: lose weight in 3 days with this diet

Those who easily gain weight have problem losing kilograms. A lot of people decide to take on diets which exclude fat or even starve in order to lose weight, which is not a good method at all. You will only harm your organism and even get sick, since you deprive your organism from the necessary ingredients.

If you have a special occasion for which you intent to quickly lose weight, we recommend the tuna diet with which you will be able to lose around 5 kg for 3 days. Practice the diet for three days and you will be surprised how quickly you will begin to lose weight.

Tuna is a fish which lives in salty water and it is rich in omega 3 fatty acids, anti oxidants, vitamins, minerals, proteins and many other nutrients necessary for our organisms. It is considered to be one of the healthiest ingredients in the world.


Since it is rich in potassium, it lowers the blood pressure and maintains its stability

Being rich in vitamin B, it improves the immunity, metabolism and has a good effect on the health and skin

Only two portions of tuna per week can help you lower the triglycerides level. High triglycerides can lead to increase of “bad” cholesterol, while the lowering of triglycerides level leads to increase of “good” cholesterol.

It is rich in proteins and helps in body weight control. Omega 3 fatty acids help with obesity and regulate the secretion of insulin in the organism. Also, it stimulates the leptin secretion which is the hormone that controls body weight. Tuna is low fat and low caloric so it is very good for obese people.

Omega 3 fatty acids are great for the heart’s health and prevent cardiovascular diseases. They also prevent the appearance of blood clogs and protect the organism from stroke or heart attack. Five or more tuna portions per week can lower the chances for stroke up to 30 percent.

Research showed that regular tuna consumption lowers the risk from breast and kidney cancer.

Selenium is an antioxidant and tuna contains it. It strengthens the immune system which makes the organism resistant to diseases and infections.

You can use only salt and ground pepper to spice up the meals during this diet. Use salt as less as possible, since tuna is naturally rich in sodium and too much salt can lead to excess sodium in the organism. Those who are allergic to any of the mentioned ingredients should not practice this diet. If you decide to begin with the diet it is important to intake a lot of water- at least 8 glasses daily.
