Tuna and Water Diet
Ready for a hardcore diet to get lean in a matter of days? This tuna fish diet is used by professional bodybuilders to prepare before the competition. It requires an iron willpower but guarantees 100% results.
3 Day Tuna Diet
Here is how it works:
- Normally this diet is followed for 3 days.
- Take in 6 equal tuna servings. Once each 2,5 – 3 hours.
- Drink as much water as possible. At least 3-4 liters. Water fills your stomach and? helps you not to feel hungry. There is no limit. Drink as much as you can.
- Take at least twice a day some vitamins. This is crucial since you won’t get much vitamins from tuna during this diet.
- You will need at least 1 to 1,5 grams of protein per pound of your weight (aroung 3 gram per kilogram).? Tuna’s marvelous as it contains 26 gram protein per 100 gram tuna. Here are two handy formulas to calculate your tuna serving size:For kilogram calculation: (bodyweight * 3 * 100) / (6 * 26) = bodyweight * 300? / 156 = 1 tuna serving (in gram)
For pound calculation: bodyweight * 100 / 156 or bodyweight * 150 / 156 = 1 tuna serving (in gram)
Don’t think it is an easy task, but the harder the task, the greater the payoff. For beginners I suggest to start the diet on friday evening after the work and keep it for two days. The reason is that you cannot control the regular food intake very well during a workday as you work normally 4 hours (or more) non stop and get only one break to eat. Moerover, two days tuna fish diet is not as hardcore as 3 or 4 days. I recommend this for all beginners. If you can keep this diet for two days without problems, wonderful, you can keep it for one or two days more.
Stay strong and be aware of forbidden foods. Your energy levels may fall in the first 1,5 days. You may feel very weak as never before. This is teh time of your spirit to stay as hard as iron and keep the diet! Your body will soon adapt and the strenght will come back.
Personally, I am doing this diet at the weekend every 2-3 weeks. It helps to burn the extra fat I may have gained during that period. It is a wonderful way to stay lean 365 days a year!
Update: Best read

Wow, I’ve got tons of emails and questions regarding this diet over the past two years. Here’s a tip to all of you who need some ideas to combine tuna with healthy veggies: get this book from amazon which is absolutely awesome: The Anti-Inflammation Diet. Apart of being a great read on what food has anti-inflammatory effect (which means less risk to get cancer) it has a few awesome recipes with tuna like the Granny’s Tuna Salad (my all-time favorite)!
I have a very odd work schudule. I have two jobs and at one I work for 6 hours and no breaks. Should I just start after that day and work around that job, or just chug water like there’s no tomorrow while there? Advice please.
Also when I start the tuna diet I might try it for a week and I think having someone to e mail or text would make it easier. Michelle.head@vzw.blackberry.net

@rachel
hey rachel i wondering coz i read your comment and i am inspire in the result.. and i want to try it..so give me also more advice.. okey thanks..
I’ve just completed this diet plan and it works. I have lost 6.2 pounds in just 3 days by just eating tuna and drinkings lots of water. The hardest part of the diet is the first day and half then its get much better.
I must say I hardly ever felt hungry during the 3 days, this was probably because I was drinking lots of water which helped in making me feel full. If your thinking about trying this diet to lose weight, do it for three day and you will lose weight that is a guarantee.
has anyone done the diet for a long period of time becuase i think im going on it to lose 80 pounds or so i know its not healthy but neither is my weight! i also think watermellon would be a good one because its mostly water! well let me know if anyone has done it for a while
@Mish
Water helps Mish. Just keep yourself in balance. The biggest enemy is if you feel too hungry: cortisol is flushed into your blood and the risk of getting back to junk food gets higher.
@Keith @ My Body Fat
Congrats! Superb result. Water does the trick.
@holly
I think, there were earlier user comments that have done this diet for several months. Although I do not advise it, you could try mixing it with lots of veggies so you have supply of the most important minerals and vitamins.
I wouldn’t chose watermelon because (1) it’s a carbs BOMB in water (2) it flushes all the water out of your body, which is not so good in this diet.

Ok!I have a question that would be on the long term like in cycle format. I have begun a new weight training program and really just want to shed the excess belly fat. I will be lifting free weights, biking and just regular cardio. I also will be taking a protein shake that will have high grams protein in conjuction with creatine and a multi-vitamin. Would the overload of protein just get flushed out. Can this diet be applied and see the same results or maybe even better? Thanks in advance.

Is it ok to mix mustard in with the tuna since it has no calories, carbs or fat? Can I have diet soda instead of black coffee? Is it ok to switch up the tuna with chicken?
Hi everyone, my name is John and I’m currently deployed in Iraq and been here for 3months, anyhow that’s neither here or there. So I’ve been trying “A tuna diet” for 3weeks, not anything specific to this diet and it has been working out pretty well. When I started the diet I weighed 185lbs and now I weigh 172Lbs. (could be a combination of the diet + the constant exposure to 115~Temp + working out) Not everyone has this capability to do what I have set in stone for my diet but it might be something you could consider and tweaking to your life style… I’ve pretty much been trying to get this down to a science… so here goes..
My Daily: BMR = 2752(Basal Metabolic Rate calculated by doing my weight times 16 is just a rough estimate on your daily allowance with your body just burning calories throughout the day), Calorie intake = 1600 plus or minus 100~ calories, protein intake 188g~, fiber intake 4g~, and a 1 a day multi-vitamin. (breakfast consists of 1 Protein shake, 2boiled eggs, 2 slice of sausage, a cup of whole grain Oatmeal or Coco Krispies Cereal with milk *I have to have my cheating happen somewhere lol* water and a banana) 1hr exercise morning, (Lunch consists of One and a half can of Tuna, protein shake, and water) 1hr exercise afternoon, (Dinner consists of One and a half can of tuna with a fresh green filled salad *olive oil and vinegar*, some fruit, and water) 1hr work out evening.
One Can of Tuna consists of 100-120Calories
One Protein Shake consists of 270 Calories
2 Boiled Eggs 140~Calories
Coco Krispies Cereal with Milk 160~ Calories
Misc fruits – fills in the gaps lol
@Sparky
i lost 114 lbs in about 7 months by eating nothing but tuna straight out of the can. i wont lie it is very disgusting after a while. i used lighte tuna and it has 100 cals per can. all i ate was5 cans of tuna a day and drank diet soda. 114 pounds in 7 months. its hard to acheive that with surgery. just exercise as much as you can and you will have results quickly i promise. for my whole story email me at drewsnider04@verizon .net

If there is any other advice you would like to give me please feel free. Thank you all for your time and cooperation!!!

@Keith @ My Body Fat

Hey everyone!! currently this is all i been eating for the past month, this(salmon too) and basic vegetables and whole grains. Not to mention i also been drinking tons of water. As a result i am getting really lean and strong(140lbs from 155, very lean)..eating fish to get lean is pretty logical…..do you see any fat on fish??? start eating it and you’ll see it happen.. peace
