I found this very interesting article that I thought I might share. Science proving that all those pills and potions were never going to help me! Thank goodness for a fabulous surgeon! When we lose weight, where does it go? Ruben Meerman & Andrew Brown The world is obsessed with fad diets and weight loss, yet few of us know how a kilogram of fat actually vanishes off the scales. Even the 150 doctors, dietitians and personal trainers we surveyed shared this surprising gap in their health literacy. The most common misconception by far, was that fat is converted to energy. The problem with this theory is that it violates the law of conservation of matter, which all chemical reactions obey. Some respondents thought fat turns into muscle, which is impossible, and others assumed it escapes via the colon. Only three of our respondents gave the right answer, which means 98 per cent of the health professionals in our survey could not explain how weight loss works. So if not energy, muscles or the loo, where does fat go? The enlightening facts about fat metabolism The correct answer is that fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat. If you lose 10 kg of fat, precisely 8.4 kg comes out through your lungs and the remaining 1.6 kg turns into water. In other words, nearly all the weight we lose is exhaled. This surprises just about everyone, but actually, almost everything we eat comes back out via the lungs. Every carbohydrate you digest and nearly all the fats are converted to carbon dioxide and water. The same goes for alcohol. Protein shares the same fate, except for the small part that turns into urea and other solids, which you excrete as urine. The only thing in food that makes it to your colon undigested and intact is dietary fibre (think corn). Everything else you swallow is absorbed into your bloodstream and organs and, after that, it’s not going anywhere until you’ve vaporised it. Kilograms in versus kilograms out We all learn that “energy in equals energy out” in high school. But energy is a notoriously confusing concept, even among health professionals and scientists who study obesity. The reason we gain or lose weight is much less mysterious if we keep track of all the kilograms, too, not just those enigmatic kilojoules or calories. According to the latest government figures, Australians consume 3.5 kg of food and beverages every day. Of that, 415 grams is solid macronutrients, 23 grams is fibre and the remaining 3 kg is water. What’s not reported is that we inhale more than 600 grams worth of oxygen, too, and this figure is equally important for your waistline. If you put 3.5 kg of food and water into your body, plus 600 grams of oxygen, then 4.1 kg of stuff needs to come back out, or you’ll gain weight. If you’re hoping to shed some weight, more than 4.1 kg will have to go. So how do you make this happen? The 415 grams of carbohydrates, fats, protein and alcohol most Australians eat every day will produce exactly 740 grams of carbon dioxide plus 280 grams of water (about one cup) and about 35 grams of urea and other solids excreted as urine. An average 75 kg person’s resting metabolic rate (the rate at which the body uses energy when the person isn’t moving) produces about 590 grams of carbon dioxide per day. No pill or potion you can buy will increase that figure, despite the bold claims you might have heard. The good news is that you exhale 200 grams of carbon dioxide while you’re fast asleep every night, so you’ve already breathed out a quarter of your daily target before you even step out of bed. Eat less, exhale more So if fat turns into carbon dioxide, could simply breathing more make you lose weight? Unfortunately not. Huffing and puffing more than you need to is called hyperventilation and will only make you dizzy, or possibly faint. The only way you can consciously increase the amount of carbon dioxide your body is producing is by moving your muscles. But here’s some more good news. Simply standing up and getting dressed more than doubles your metabolic rate. In other words, if you simply tried on all your outfits for 24 hours, you’d exhale more than 1,200 grams of carbon dioxide. More realistically, going for a walk triples your metabolic rate, and so will cooking, vacuuming and sweeping. Metabolising 100 grams of fat consumes 290 grams of oxygen and produces 280 grams of carbon dioxide plus 110 grams of water. The food you eat can’t change these figures. Therefore, to lose 100 grams of fat, you have to exhale 280 grams of carbon dioxide on top of what you’ll produce by vaporising all your food, no matter what it is. Any diet that supplies less “fuel” than you burn will do the trick, but with so many misconceptions about how weight loss works, few of us know why.

Way to go! Congrats on finally getting somewhere with this one. Weight loss surgery was the best choice I have made in a bloody long time - no more hiding behind the camera, no more big, baggy clothes, no more wasted years!!
I am only 16 weeks post op and have plateaued a few times. It is frustrating but I remind myself that I haven't put the weight on - it is still coming off! Sometimes very slowly BUT the numbers on the scales are definitely going down. Exactly as Denzel says "Be kind to yourself." The numbers will take care of themselves. If I had been able to lose 1-2kgs a week, I would never have had to embark on surgery in the first place. Start to work on the inner journey to find acceptance and love of yourself. I personally have found this the hardest piece. Congratulations on your weightloss to date, there's more to come
I have to admit that I "cheated" on the puree stage. I had made myself one lot of pureed food and did not enjoy it. I ended up buying little jars of baby food, and they were perfect! I stuck with the 6 months and under group, and found that they were also the perfect size. I had also stocked up on pre-made jelly, which all ended up in the bin because I could not stand the taste! Scrambled eggs were always a great fallback. (Actually, just one egg scrambled - anymore was too much!) Just be aware that your taste buds may change and your tolerances to certain foods may alter.
My GP would not sign my forms either, despite referring me to a bariatric surgeon. Fortunately, I had gone through Supercare - happy to pay the $780 so I didn't have to deal with the bureaucracy. Supercare put me onto an online GP who was given all of my information and the wheels started rolling again. Don't despair. There are ways to get to the end result.
Hi LouisA I too was sooo sick after surgery. Vomiting for 2 days, wondering if anyone got the number of the bus that had hit me. I also sincerely wondered "What the hell have I done?!" Obviously get the medical professionals to check you over, but please believe me when I say that it gets better day by day. In those first two days I was convinced I had made a massive mistake. By day 3 I was able to keep small sips of fluid down. I still had bouts of nausea but nothing like the first two days. Hope today you're feeling better than yesterday, and tomorrow even better still.
Love reading the posts on here. Good and bad. I was "sleeved" in November 2017. My start weight was 118kg (I'm 5'11"). After the pre-op Optifast, I was at 114kg. 3 months and 2 days later, I am LOVING my decision!! I'm down to 90kg - a loss of 28kg (with 13kg more to go until my target). The Pros, for me, are; Not having to be consumed with the multi billion dollar diet industry fads any more. A hard one to admit, but I tried hundreds of different "diets" only to fail time and time again.Having a "Full" or "Stop" button on my food consumption. Was so sick of hearing people tell me to just stop eating when I was full. I was never full - so I never stopped!The reduced pressure on my joints - ankles, knees, hips, and spine. I no longer feel like an 80 year old invalid (I'm 49)The additional energy levels.A wardrobe that I am liking more and more!The Cons (if you want to call them that) Tastebuds that have changed. I used to looooove a McLaren Vale Shiraz, but these days far too heavy for me. In fact, my alcohol consumption is probably down to about 2 glasses a week, as opposed to 3 bottles a week! (No idea why I was such a heavy beast )Ordering a meal out and only getting 3 - 4 mouthfuls in before I pass it over to my husband or son-in-law. It is like eating a couple of chips in front of seagulls...It has just begun for me, but from all accounts, I am pretty confident that this is one of the best decisions I have ever made.
Sure did! If I could have stuck to the pre-op diet for two weeks, I would have been able to stick to a better diet full stop! Fortunately, it did not affect my surgery. My liver was in great shape, so I got lucky. I can only say to those that fall off the pre-op wagon, don't fret too hard. Get back on as quickly as possible and try your absolute, and honest, best to stick to it. Speak with your medical/nutritional team and get their feedback.
AJS78 - Please keep updating as I would love to follow your progress. I was sleeved on the 20th of November, and I think it would be interesting to see how the comparison goes. Don't get me wrong, I realise it is an individual path and everyone's results will vary.
I'm guessing I made an error of judgement. 17 days post op and on the mushy food. I was craving something sweet so blended a banana, half a mango, and a third of a tin of coconut cream. I ate three tablespoons of my concoction about 5 hours ago, and have been nauseous or sitting on the toilet ever since. This is going to be an interesting ride, understanding what my new stomach will and won't accept!
