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)!
Hi,
I really would like to lose about 25 pounds and look good in shorts and a swim suit by the summer. After being on the diet for 3 to 5 days can fruit and veggies be added along with having oatmel or a boiled egg for breakfast?
I also have thyroid problems, will that effect my progress?
Tyson makes a can of chicken chunks with pretty much the exact nutrition facts, but with more protein..If I do the diet with the chicken, will it be the same as the tuna diet…If so, could I eat both of them? You also say fruit doesnt hurt and eat as much as you want, what about veggies?..Can I eat any with this diet?
I am 22 years old, and while my fiancee moved out of state I stayed with my mom until he got us our place. I didn’t like most of what she ate, so I pretty much LIVED off tuna sandwiches and water for 8 months. It’s very hard for me to lost weight, and without even knowing about this ‘tuna diet’ or exercising, or trying at ALL, I lost 25 lbs!!! Slowly people were telling me how skinny I was and I had no idea why I was losing weight. I know the diet says you aren’t supposed to eat bread because it counteracts what the tuna is doing… So why did I lose that much weight eating tuna sandwiches? Since I moved back in with my fiance I haven’t been eating those and have gained it ALL back!!! (I just sent him to the store to get more tuna!)
OK, here goes. I attempted this diet yesterday. However I feel super starved in the morning before the gym, so I have a cup of nonfat plain yogurt. Following the day with Tuna, while on the go Low carb Protien Bars (2) then Tuna and another Cup of Yogurt in eveing. Today I feel super tired. lighter over all. I plan to eat more tuna and only one bar a day. plus one cup only of yogurt. i do not like the idea of straving. This way I feel light but not straved throught the day. What do you think of this plan. Am I wasting my time??
Probably because you changed your diet and your caloires were in the very low range over all.It would og happened if you ate only ice cream too. After all eatting low cal will keep you losing weight,till your body says enough and starts to store fat to protect you. You accidentaly become a YoYo dieter,too low calories followed by eatting normal or more then normal equals fat gain and fast. Your body clearly went into strave mode. You can’t live off only tuna sandwichs. There is not enough vitamins etc…Try to eat balanced. You will get back on track. I lose 15 lbs in 1 month or so from cutting out sugar, excerising like mad. I gained it all back lus some and have found it difficult too lose. The body is not always our friend. More like a parent.
I am going to do this tuna diet for 15 days straight but I am also going to use a supplement shake as well that I bought from Arbonne called Figure 8 so I can make sure I get my vitamins! If I feel I have to have a snack I plan to eat raw fruit!
I will let you all know how it works for me I am starting it April 1st & ending April 15th!
I am 5’3 and 155 pounds. I really want to lose weight, thats why am going to start this diet on monday 7th. Am going to do it for a week. I wish i lose 10 pounds at least! i dont know if i could do exercise because i guess i will feel tired and with little energy…well i will type my final results on april 14.. wish me luck!

hi if i start on may 1st and follow it for the whole month is that recommended because this is the only diet that has ever worked for me i really want to get lean fast and keep off the weight i am 225 and 6ft. any help or advise would be appreciated thank you
Guys, read the warnings above! When they say do not follow this diet for more than 5 days max they mean it! This is not a diet you can, or should, consider for long term use. This diet originally came from bodybuilders in the 50′s as a way to deplete their bodies of sodium to make their skin look tighter and more vascular. Yes, you will loose some fat but most of the weight you loose will be water. This can be very dangerous, especially in the summer when temps are high.
If you want to do this for 2 days before a photo shoot then fine, do it. But if you need to loose 15 pounds in 2 weeks to look good at the pool you’re out of luck. You should have started 7 weeks ago to meet your goal.
Once again. Listen to the advice of the publisher and only follow this diet for 2-3 days.
Hey I have been doing the Dave Draper tuna and water diet for 2 days now 1.5 grams of protein for every pound of body weight I have to eat 9 cans every day but it is working magnificently I have not weighed myself but am already seeing definition and such this works great I am doing this for 9 days it really helps to add metamusil though. =P
I Think Sparky Died
Lol, Tornado. I have laughed my a** off on this one! =) I’m alive as never before. Good diet combined with excellent anabolic/aerobic exercises do the trick. Yo guys ever tried spinning? Yo should! It’s so fun and addicting! And it burns those michelins in no-time. I should write a post about it sometime as soon as I get few minutes free…
i have been eating carton eggs that have 30 calories per serving ( am eating 2-3 servings) with fat free cottage cheese 1 serving for breakfast Both have very little carbs . Then eating strictly tuna after for the rest of the meals. IS the breakfast alright?
Can’t figure out the formula.
How many cans of tuna a day??
hi guys, i am 5’6 and i weight 190lbs…how much tins of tuna wud i have to eat per day..some one please help me out….i am too fat and it has to go
Rori,
From what I have read, you should get 190 to 300 grams divided in 6 servings per day of Tuna. And drink as much water as you want.
I plan on starting this diet tomorrow. However, I’d like to incorporate some baby spinach in mine during Lunch time.
Good luck.
And oh, don’t forget your vitamins and some metamucil in the evening.
hey i just read this today and im really interested in trying this out
i shall start first thing in the morning tomorrow!
hi sparky, i am a little confused but some of your previous comments with regards to the amounts of each serving. i’m just finishing off day 2 of this diet, but something tells me i could be eating too much tuna!
currently i’m eating 6 cans per day, (alot i know!) but according to forumal:
“You will need at least 1 to 1,5 grams of protein per pound of your weight (aroung 3 gram per kilogram).
For kilogram calculation: (bodyweight * 3 * 100) / (6 * 26) = bodyweight * 300? / 156 = 1 tuna serving (in gram)
found in the introductions i’m suppose to take in about this amount. please can you elaborate on this? my weight is roughly 90kg…
(after 2 days with exercise its around 88kg)
thanks
I really whant to loos weith ok but my worry is that I will gaine weith by eathing tuna I think that i can do it i just dont whant to gain the way ok

Tuna for breakfast, tuna for lunch, 3 days of tuna..But I munched a piece of red peppers down with it, and I mixed mustard in the tuna. Not to bad actually. Ill let you all know how it works…Im bad with water,but…you have all inspired me to do this. When do I weigh myself? Three days, next week?…lol I figured I am suppose to be eating 4 oz of tuna 6 times a day? Did I calculate it right? Anyways, hope to be 20 pounds down SOON….real soon, headin to VEGAS!..
RAYZA…..congrats….I want to be just like you. 12 pounds in 4 days…lord have mercy..that is great…and it was just tuna and how much water really? Can you tell me exactly how you did it? PLZ….I am counting on you all for your inspiring comments..

HEY..SPARKY..I do not think I am the only one who needs help with this..I am TOTALLY not understand the point of workin out how much tuna I eat. I figured out 4 oz, but gee…readin others notes? Im banging my head. Can you please help us out with this?
OK…I figured it out…Ok whoever is tryin to fig this one out…I have the solution…go to google, and get the charts converting (kg to pounds), (grams to oz) and (grams to pounds)….IT SO helped me…I am 223, and I am to take in 3.5 to 4 oz of tuna per serving. WOW….that was brainer work…lol…
im about 180, and i am eating 1 oz per serving is this right?… this would mean 1 can per day right??… also can i eat lettuce and diet soft drinks?… thanksss
OK GUYS….THE HUGE NEWS….I doubted this, cause nothing works for me. THIS DID…I was 223 to 225 3 days ago….I AM 218.2, with 37.2 body fat now….YOU have NO idea how happy I AM ….IT IS AMAZING. I AM SO EXCITED…AND THIS IS DAY 3….Im doing it for 4 days, Ill let you know wjat happends…I would be delighted to loose 20 pounds by OCT….
HEY CARLOS….you are suppose to have 110 grams of TUNA 6 times a day….that means in oz, you are to have 3.5 oz 6 times a day…What I find easier is, to get down tat tuna…and you will get your water down at the same time…eat a fork full and take a drink to get it down right away…I have not had anything else…Just the tuna and the water…I did add mustard as well, and it was not all that bad…and then another day I added hot peppers, to give it a little taste…THE THING IS NO CARBS…check the carbs and 0 cals…I am not a perfectionist on this, but heck its workin for me…SO….LET me know how you are doing too….we all can support each other…
HAPPY FAST WEIGHT LOSS…..
CRASH!
YOUR prob wondering..well how is that possible cause I weigh more….Well, if you do the pounds equasion you will come up with a differnt number then me, YOU ARE 110, and I Am 135….the grams and oz conversion chart that I got off og google, goes by hundreds…you are closer to that 100 more then I am and it says 3.5. I am eating 4….SO…yes…you are 3.5 oz per serving. 6 times a DAY….Im not eatin all that though…I have not been hungry…BUT AFTER 7 8pm…I find that I Am starting too….snack on some carrots…or red pepper….
Is it safe to use this diet every week?
Deidra, if you complete your diet with vitamins (i.e. a lot of fruits and veggies) I suppose, it would not hurt. However, I wouldn’t do this kind of a diet more than twice a month.
Funny I left a post here more than 2 years ago! I know how good the tuna diet is buttt I can’t get myself to eat tuna anymore… I’m starting tom… I currently weigh 72kgs need to reach 58kgs in just about 6 weeks.. I’m doing
Sparkyyyy can I achieve that goal?
What sort of work out should I follow? I don’t wanna sag
The tuna diet works!! i lost 10 in 3 days and feel great.
Good Luck Everyone.
hey,
i would like to INCREASE my body weight by gaining muscle, and i would like to know if tuna is suitable for gaining weight due to the high protien. should i add tuna to a healthy diet instead of replacing the carbs? are thier any other foods that any one can recommend?
thankyou!
hey Sparky, read pretty much most of the comments and this sounds good, i have 2 weeks to go back to uni, and i want to lose atleast minimum 10lbs, thats possble with this tuna and water diet right?
and so if i do tuna and water for 4 days and the next 3 days of the week add in fruit and veg will that be good enough? and then the 2nd week repeat it all again?!
altogether, i want to lose 14lb-21lb depending on how i feel after ive lost some, but for these 2 weeks kickstarting 10lb would be just what i need.
BTW HOW MUCH WATER WEIGHT ISIT?
please do reply… i know you get alot of msg’s so it must be quite hard replying yo everyone….
tc

started the diet today…. had 2 cans of tuna and black coffee with one spoon sweetner…….. but i didnt get chance to eat anything until the evning at 7pm… is that bad?
so i had my main meal… meaning anything which went past my mouth at 7pm 2 small cans of tuna..and i am stuffed for some reason..
another question. exercise? i dont feel like doing any today as im too tired but if i workout for the next 3 days and not do anything for the first day of the diet is that ok or do i have to workout everyday?
Aliyah,
you feel tired because you’re either stressed at work or have an unbalanced diet. That’s why it’s important to have 5-6 SMALL meals throughout the day. Keeps your energy levels constant without any insulin spikes.
I guess at least half an hour of exercise is a must. Even if you don’t feel like it. Jeeez, it’s only 3 days! Clinch your teeth together and JUST DO IT!
And don’t forget those fruits and veggies!
Hope that helps and good luck! Post your results here when you finish
lol yeh true i went to the gym for half hour…. well these 3 days i will jus have water and tuna and black coffee and then add fruit and veg after the first 3 days right?
im hoping to lose minimum 7lbs in 2 weeks is that possible?
4 days of this and then add veg and fruit and workout half hour everyday?
thanks for the reply spiky
