  1. Re measurement of obesity accuracy.  Waist-to-height ratio

    Calculating a patient’s waist-to-height ratio is the most accurate and efficient way of identifying whether or not they are at risk of obesity, a new study shows.

    The research, published in PLOS One, examined the whole-body fat percentage and visceral adipose tissue mass of a group of 81 men and women.

    The British authors discovered that 36.5% more adults would be classified as obese using whole-body fat data (one in two participants) rather than BMI (around one in seven participants, or 13.5%).

    To conduct their study, they gathered accurate whole-body and abdominal fat data using a total body dual energy X-ray absorptiometry (DXA) scanner — a highly accurate way of measuring body composition and fat content.

    They then calculated five predictors of whole-body fat and visceral adipose tissue that could be easily replicated in a GP’s office, and compared the results with those of the DXA scan to determine which simple predictor of obesity was the most accurate.

    The five predictors tested were: BMI, waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and waist-to-height ratio0.5 (WHtR0.5).

    Lead researcher Dr Michelle Swainson, senior lecturer in exercise physiology at Leeds Beckett University, says although there are benefits to the conventional BMI method, there is concern that it is a misleading measurement.

    “This is most definitely the case when people have a 'normal’ BMI but high abdominal fat that is often dismissed,” Dr Swainson says.

    The results from the study show the best predictor of whole-body fat percentage and visceral adipose tissue in both men and women is WHtR.

    This simple method of waist circumference divided by height measurement is not a new obesity classification but, despite evidence supporting its use, it is still not routinely measured in clinical settings, the authors note.

    Cut-points for predicting whole body obesity were 0.53 in men and 0.54 in women. The cut-point for predicting abdominal obesity was 0.59 in both sexes

    ive indication of obesity, it appears that height/waist circumference is a better measure. 

  2. Hi @rumplebear

    Pre-op  my dietitians long term weight goal for me was 53 kg (+/-3 kg) - She arrived at this by using the formula:  your height in cm - 100 +/- 3 kg e.g. for me height 153.5 cm - 100 = 53.5 kg +/- 3 kg.  She asked me what I would like to be, and I hesitantly said 50 kg - never imagining that I'd reach that magical number!  I actually got down a lot lower - BMI 17.5, weight 41.3 kg - my GP was very concerned -  in the first year (due to sickness).    Then I slowly regained weight, and got up to 50 and wasn't happy when I saw some photos taken of me at that weight.  So slowly lost, aimed on 46 kg (didn't get back to there).

    I found my "happy" weight around 47 kg, so that is my goal long term weight, hence it's a personal goal weight.

    Following 7 months of hideousness - Cymbalta withdrawal and POTS I put on 8 kg,  bringing me up to 54.8 kg and an increase in 2 clothes sizes! Most of which I had earlier ditched lol!  I simply could not stop eating.  I think that my body was screaming out for energy.

    So, once I started feeling better - back on Cymbalta for Fibromyalgia + it has the wonderful side effect for me of decreasing my appetite - I have been slowly losing weight - nearly back at my original goal of 50 kg, but then of course, my next goal is to get back to 47 kg.

    What are your thoughts? Should I have a goal weight?

    This has to be an individual decision.  But for me - and others - it gives us something to aim for in the initial weight loss stages, and in maintenance (for the rest of our lives!) - helps to stop complacency and being aware when we are regaining weight and therecore can put a curb on it.

  4. @Bigm666 You will see a Bariatric Specialist Dietitian pre-op - go for whatever they recommend for the first, say 3, months.  Chewable/sublingual - these don't put strain on your new tiny tummy - takes 10 weeks for the incision (stomach) to heal.  Then after that, IMHO, then brands such as Swisse are fine.  And eat healthy, nutritious food that gives you bang for your buck nutrition wise.

    Hi All, with a preoperative diet can you have any fat and if so, how much?




    Hi, sorry I can't answer that.  Thankfully I didn't have to do a pre-operative diet!

    I can thoroughly recommend that you see a Dietitian specialising in Bariatric Surgery for support and guidance during every stage pre and post-op diet wise.

    All the best!

    Denzel, I just shake my head every time I read about your weight. You are such a dainty person at 51kg - I'd be worried about you blowing away in a strong gust of wind.


    I am short - really short! :wacko: I have the height of an average 12 year old.

    Thankfully my weight now is in proportion  to my height. When I was 82.5 kg I was in shape all right - round! (I don't have any photos of then, but do of when I was around 76 kg.  Hideous. No wonder folk don't recognise me now lol!)
