Changes in appetite, taste and smell are par for the course for people who have undergone Roux-en-Y gastric bypass surgery during which one’s stomach is made smaller and small intestines shortened.
These sensory changes are not all negative, and could lead to more weight loss among patients, says Lisa Graham, lead author of a study by researchers from Leicester Royal Infirmary in the UK.
Their findings, published in Springer’s journal Obesity Surgery showed that after gastric bypass surgery, patients frequently report sensory changes.
Graham and her colleagues say their day-to-day experience with patients who have undergone gastric bypass surgery suggested these changes, but surprisingly little has yet been written about it in scientific literature.
To this end, questionnaires were sent out to patients who had undergone the procedure at the University Hospitals of Leicester between 2000 and 2011. In total, 103 patients answered the 33 questions about appetite, taste and smell set to them. Of the respondents, almost all (97 percent) reported changes to their appetite after having the surgery.
Their experiences varied, with subjects reporting that their sense of smell and taste were either unchanged, heightened or reduced.
Forty-two percent of respondents said their sense of smell changed. Seventy-three percent of patients noted change in the way food tasted, and especially in their sweet and sour palate. Respondents especially noted a change in the taste of chicken, beef, pork, roast meat, lamb or sausages, while fish, fast foods, chocolate, greasy foods, pasta and rice were also high on the list.
Three out of every four (73 percent) patients noted that they had developed an aversion to specific foods after the surgery. Meat products topped the list, with one in every three patients steering away from chicken, minced beef, beef steak, sausages, lamb, ham or bacon.
Starches such as pasta, rice, bread and pastry and dairy products such as cream, ice cream, cheese and eggs were a no-no for almost 12 percent of respondents. Only 4 percent of respondents reported having an aversion for vegetables, 3 percent for fruit, and 1 percent for tinned fish.
Interestingly, patients who experienced food aversions enjoyed significantly more postoperative weight loss and reduction in their body mass index (BMI) compared to their counterparts without such dislikes. They typically experienced weight loss of around 8 kilograms and a loss of BMI of 3 kg/m2 greater than their counterparts.
It is still unclear what the role is that perceptual changes in the taste and smell of food play to influence calorie intake, meal composition and subsequent weight loss following bariatric surgery. However, Graham believes the sensory changes are due to a combination of gut hormone and central nervous system effects.
“This study indicates that subjective changes in appetite, taste and smell are very common after Roux-en-Y gastric bypass,” Graham summarizes the findings of the study, which are in line with that of other ones done. Patients are

<p>Question by World Dominator M: Question to people bodybuilding?
For about a year, I have had fatloss in focus. Now, I want to try gain some muscles. I have been training with weights for my fatloss too, but my diets have not been very big. Im looking at some articles on BodyBuilding.com now on suggested diets for their workouts, and they are HUGE! I will probably end up eating ‘almost’ twice as much as I eat today. Im a bit scared of having this turning the wrong way, and end up with just gaining fat weight again due to too many calories. My weight training have almost stopped though, its hard to lift any heavier than what I do today. And if I push myself, Im extra exhausted the next day and have to decrease even lower – keeping myself on the same stage day after day.
I cant be the first person in this situation. Any tips? My weight is 80kg, or about 176 lbs.
Thanks to both 🙂 I guess Ill have to research mostly myself, as I get more and more confused the more I ask… But Ill start easily and then see how it goes 🙂

The best tip I can give you is to stay away from bodybuilding.com and other websites like it. Don’t study bodybuilding and don’t get information from those who do.
Don’t use bodybuilding.com. It’s a scam-site for the purposes of selling supplements and is full of bad information. They recently paid a $ 7 million fine for selling illegal drugs. Check out this list of over 60 dangerous supplement products sold with bogus advertising claims which scam-site bodybuilding.com was forced to recall and take off the market here –> http://www.usrecallnews.com/2009/11/bodybuilding-com-supplements-recalled-may-contain-steroids.html and here –> http://www.fda.gov/ICECI/CriminalInvestigations/ucm305494.htm . More here –> http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAlertsforHumanMedicalProducts/ucm188957.htm?nav=rss and still more here –> http://www.youtube.com/watch?v=oE0qAd-8d2Y&feature=plcp and here –> http://www.druginjuriesfirm.com/Blog/2012/May/Bodybuilding-com-Pays-7-million-Fine-for-Food-an.aspx . Their information is bad because they don’t screen it so they have a ton of information to attract the suckers.
Bodybuilders all have different stories, different techniques, and different information. The reason for that is none of them have any science to keep them on the same page…saying the same thing. They just pass along whatever myths and nonsense they picked up at the gym or from reading bad information in muscle magazines (which exists to sell supplements and equipment) or websites which are just as bad. If you want to build muscle, study exercise physiology.
Your body has no choice but to follow your brain. So, you should feed your brain a steady diet of good information if you want to be all you can be. It’s YOUR body and it has to last a lifetime so it’s worth the investment. Don’t ask questions of random strangers with no credibility in this or other online forums. Use high quality resources for information instead. The basic principles of health, fitness, and nutrition are not that difficult or hard to understand.
Avoid the internet unless you’re using trusted sites in dot gov or dot edu domains. The dot coms are usually driven by profit motive and you’ll find bad information in most websties including WebMD, Livestrong, Bobybuilding.com, etc. and especially in this forum and others like it.
Use books, especially late edition text books. You can find excellent information resources at your local public or Uni library or for sale cheap online at Amazon.com and Ebay.com.
Always follow the science. Use critical thinking. Be skeptical and do not believe anything without cross checking it with trusted sources. Grow your personal knowledge base and everything else will follow with relative ease.
Here are two excellent books —> http://www.bodybyscience.net/home.html/?page_id=18 . You might be able to find copies cheap on Amazon or Ebay.
Good luck and good health!!

Hearing his voice or watching him lift = preworkout like no other
Fantastic advice from a fantastic man.
Oh so this video is an advertisement for BodyBuilding.com/s supplements.
Once Arnold started talking about how you can’t get all the protein you
need from regular meals, I realized it was just a plug for the website’s
sale of protein powder. Don’t be duped, folks. And Arnold’s an awesome guy,
but I know when someone is trying to sell me something. I’m not falling for
it, nor should you. Peace :)

It’s tough to add muscle while losing weight. However, if you’ve reached your goal and aren’t trying to lose more bodyweight, you can start to build up. First of all, you weigh 176. You don’t need to start eating like a superheavyweight powerlifter or a strongest man in the world competitor. I’ll bet you are already eating a fairly healthy diet. Add a little protein. You want to gain weight SLOWLY, so you don’t pack the fat back on. If you’re doing tons of cardio everyday for weight control, you need to cut back. Too much cardio will kill muscle gains. Experiment to find a balance. Take your time and be smart. You’re in this for the long haul.
Your lifting program should be a basic beginner workout even though you’ve been doing some lifting as part of your weightloss. Try this: bench press, lat pulldown, squat, deadlift and barbell curls. Do one light warmup set of 15 reps followed by 1-2 heavy sets of 8-10 reps. You can add more exercises after you get acclimated and build a foundation, say in a few months. Lift twice per week. Do ab work and cardio on off days. Your cardio should be walking, jogging, swimming, biking, etc., NOT high rep calisthenics. I suggest you take a week off from whatever lifting or tough calisthenics you’re doing atm before you begin your new lifting workouts.
I know you’ve probably been doing frequent marathon style workouts and this new program doesn’t seem like enough work, but give it a try. Building muscle and getting stronger if different than working to lose a lot of fat. Best of luck and stick with it.
