Sleeve to Bypass
Since being referred for WLS in January of this year, I started to read as much research as I could, and came across the excellent: http://www.drsharma.ca/
Below I offer a summary of Dr Sharma's findings (this is combined from about 3 or 4 different articles of his, the original links of which I will post below).
A person who only needs to lose 3 stone will only need to cut their calorific requirements (post weight loss) by 20% to keep their new lower weight.
However, for an ex super morbidly obese person who uses diet and exercise to diet down from 300+ lbs to 150 lbs the homeostatic thermometer will be reduced by over 50%. The ex obese person becomes *more* fuel efficient, and needs fewer calories than a NEVER obese person of 150 lbs.
For an ex super morbidly obese (over 300 lbs) person who reaches 150 lbs they are likely to need to survive on a new reduced calorie intake, at least 25% or 30% lower than a NEVER obese 150 lb person.
i.e. an ex obese person will have to survive on 1400 calories a day to maintain their new lean size
This is extremely difficult, if not impossible, for all but the most dedicated, with a football sized stomach and an appetite that was previously used to consuming around 3000 cals per day.
It becomes possible with the aid of bariatric surgery, when the stomach is reduced to the size of an egg cup, and hunger and desire is significantly reduced for post bypass patients to survive on less than 2000 cals a day.
Dr Sharma states that the average post bypass patient does actually live on only 1400 – 1500 cals a day and due to not being able to eat so much has to make better food choices to get all the protein and nutrients they need within their limited calorie / small stomach budget.
