Man loses 250 pounds with keto and intermittent fasting


Robert’s wake-up call came when he couldn’t enjoy a family trip to Universal Studios because of his weight, 500 lbs (227 kg) at the time. But it took eight months before he took action and began a keto diet, intermittent fasting and also started tracking his food.

Once he got started, however, the 250 pound (113 kg) weight loss was apparently easy:

When I reflect on my weight loss and where I came from, I think of a movie line from Apollo 13. It’s when Tom Hanks is talking to Kathleen Quinlan after their party looking at the moon, and what it took to get there: ‘It’s not a miracle. We just decided to go.’ I just decided to go.

Men’s Health: This guy was 500 pounds. Then he cut calories and lost half his body weight.

    Congratulations! I wish my weight would come off with Keto. I feel great otherwise.

    Great job. I myself lost 70lbs in 3 months. That was 10 years ago this September. Will never go back.

    Do Keto. You add healthy fats to your diet and cut out carbs and sugar. I have so much more energy than I ever used to, I sleep better and I'm not hungry on this diet! Bacon and eggs every day for breakfast!! I love it.

    Jeff- all diets work while you do them. I would talk to your doctor first because keto is great but it's not for everyone. For example, it's rough on your kidneys so someone with kidney disease would be advised to try another method. Good luck with whatever you choose!

    Low carb is not hard on your Kidneys that's a myth. If you are finding it hard to lose weight lower your carb intake to less than 10 grames. I have begun to lose weight after being unsuccessful on the average low carb Keto diet. I feel wonderful and my excess weight is coming off a little every day, it's so exciting. I am 59 and my skin has never looked better. Good on you Robert what an inspiration!

    I took the challenge with my daughters, who really didn’t have the same problem as their father, but took the challenge anyway. I have been on Keto, with intermittent fasting, (72 hours each week for the last 3 weeks) for 8 weeks and have lost 30.2 lbs. so far. I’m 73 yrs. old and by next year, this time, I hope to reach my goal! The Fasting isn’t easy, but it is doable. I was 366.2 (8weeks ago) in the beginning and strive to be 250 or less next year! Anyone who is really serious about having a better life, should take-up the challenge of a lifetime.

    Good for you!!!

    I am really discouraged these days, I have gained weight and now have read an article on the problems with Keto with those who have had their gall bladder removed. It sounds like I may not be able to be on a Keto diet any more. I feel good while on it but really discouraged now. Can anyone enlighten me on this problem.

    I'm pretty sure they do that on purpose. No reason to promote low carb - there's no money to be made in people eating and getting healthy.

    Doing Keto is not rough on your kidneys - that is a myth. After reading all the science behind this diet on THIS website, I am surprised you would even leave a comment like that. Research and embrace the truth.

  15. Tera

    One bad article vs hundreds of articles and success stories of people eating a Keto diet is really bad math. Eating Keto does not mean you won't ever gain weight; losing a gall bladder is pretty extreme. You should take a closer look at the foods that you are eating - your problems with eating Keto probably start right on your plate.

    Laura, I had my gallbladder removed in 1986. I have been doing Keto since Oct 5, 2017 and have lost 90 pounds so far (have another 70 to go). I feel so much better. I personally have not had any problems doing Keto without a gallbladder. I am 60 years old. Best wishes.
  17. Laura
    Thank you very much. I will take a look at what I am eating. My daughter in law says that because I lost the gall bladder I should not eat animal fats. I appreciate your comments and will keep trying.

    Laura, please don't get discouraged! I had my gallbladder removed when I was only fourteen. I'm now 55 years old and started Keto in January 2018, I have lost 77 pounds and still full of energy to lose another 40😊Time goes by fast, so get started and good luck!

    Laura I also don’t have a gallbladder and am doing Keto! I lost over 85 lbs in 9 months. Go to YouTube and check out videos by Dr. Eric Berg on Keto without a gallbladder. It was really helpful with my Keto journey. I take digestive enzymes and it really helps me.
    Good luck and don’t give up just do research from credible people. I also read a lot of books on Keto and LCHF.

    Great job! I was wondering about the excess skin

    Laura, I've also lost my gallbladder and have no problem eating fats. I have read that a low fat diet my have more to do with gallbladder stones because there is too little fat to trigger the gallbladder o fully expel it contents. The bile then turns to sludge and cholesterol stones starts to form. It's sounds plausible to me, but I don't know for sure. I personally think my problems were from my undiagnosed gluten intolerance, but that's another topic. My naturopathic doctor told me the gallbladder is just a sec to hold bile. The liver still produces bile, it will just trickle out over time instead of large ejections at one time. She said if I'm not having issues it's fine to eat fat. Good luck!

    This is the most forgiving lifestyle I’ve ever journeyed on. I have lost a total of 80 pounds with 40 to go. I fall off the wagon sometimes but I don’t punish myself with negative thoughts of thinking I’m a failure. I either fast a few days or just jump right back into doing my keto plan. I am getting to the point now that falling off feels foreign. As of late it seems my body and mind reject sweets so that trip that use to take me down a long road is now very short. I love Diet Doctor because it is my go to place for all I need to know about the keto diet. I have tried “virtually” ever diet plan out there, I think, and just gained ever pound I lost back But, not this one. I feel free and vibrate after 10 years of excess pounds. 1 year keto and counting!

    I had a gastric bypass in 2013 who almost cost me me life. I lost some weight but not match and most weightloss was caused by infections after surgery.
    The gastric bypass is only a very temperary help. I schould never do it again. Now i'm busy with the ketogenic diet and for the first time in my life i have something to feight back to nu body. For the first time in my life i can loss weight and go to a normal weight. I still have a lot to go butt just as Robert "I dicided to go" because it works. I dont lissen to other people who knows always better. I will complete my Keto mission.

    I came from 180 kg and that is very much to carry....

    They said high protein intake was hard on your kidneys, not low carbs.
  25. Peter
    high protein intake is not hard on your kidneys. I know, I have bad kidneys, and so does my brother (who has had to have kidney surgery), we both lost weight on a keto diet without issues. 54 lbs of fat gone in 17 weeks 5 years ago, and it is still off. I felt so good I upped my workouts and started hiking and mountain climbing again at 56, I gained 4 lbs of muscle mass, and my body fat has stayed below 20 percent. I am in as good a shape now at 59 as I was in collage, I am more fit than most collage students now! Before I lost weight I had insulin resistance, leaky gut syndrome, sleep apnea, got regular and painful kidney stones, and a lot of other problems related to being over weight. Conventional medicine had no solutions, I was always feeling sick and tired, I could never get a good night's rest. Now, all of that is gone after loosing weight. I do drink a lot of water and green tea daily, which appears to help kidney function (I dissolved three kidney stones, as shown on a sonogram, by drinking 8 plus cups of plain green tea with lemon daily). My body is more efficient, lean, my skin texture improved, I take no prescription meds, my mind is clear and I am as productive as I have ever been in my business. Quality protein and essential fats are some of the most important macro-nutrients you can consume. A healthy diet should not ever cause health problems.

    You people inspire me. I'm coming off a binge-fest bender full of all sorts of sugary no-no's. I felt that I was bouncing up and down the same 20 lbs on Keto and grew discouraged, thus the bender. I was getting recipes from this site and that site and eating too many cheesecakes and no-sugar fat bombs, I think. I counted every trackable, journaled every bite, graphed my losses and gains, I've ballparked the carbs only and it was still up and down the same 20 lbs. I never experienced the rapid weight loss that you guys seem to have achieved. I looked at that long trip to the moon and felt I couldn't do it. It was just too hard. But I feel so horrible, so brain fogged with carbs that I just can't NOT eat Keto.

    So I've decided to go, too. I'm back on the first 7 day challenge and will try sticking with Diet Doctor exclusively to see if that does it. I am uncertain what to eat otherwise. I'm 62 and 324 lbs. I want this so bad it hurts.

    My Journey started 65 days ago just Keto no fasting and I lost 33lbs, it will be a long journey with many lbs to go.
    I am 61 and still 350 lbs but know if I don't do it now I won't make it to retirement age.
    Thanks to all who inspire me.

    Do you have to eat 800 calories on the high fat low carb diet? Sounded like that’s how the guy lost weight not a regular keto. I thought you just kept track of carbs Please advise.

    What was the result after 2 weeks?
  30. Joanna
    I’ve been following strick Keto since July 2018 - down 83lbs, no more palpations, brilliant blood pressure and other levels were fantastic. Only problem is my cholesterol (which has never been a problem before) bad level is 3x the ‘norm’ and good is twice the ‘norm’. Will this reduce as I carry on or should I replace butter on food with virgin olive oil and cut out egg yokes? Any suggestions and advice greatly appreciated.

    Laura, I have my gall bladder removed and am doing just fine on Keto/carnivore diet for over a year now. Try Ox bile that I use occasionally. And I do a lot of bacon, heavy cream, MCT oil. I am 71 now.
