I was looking on the net and found this report about the efficacy and long term success of VLCDs.
Should say right now that it was funded by a VLCD provider, but most research (or meta research, as in this case) is. It seems well-referenced and without too much bias. I haven't done any science since GCSE, but I found it fairly easy to follow, so i recommend you have a look if you like to back up your actions with the facts (as far as they are known).
Key findings for me:
Statistically there is no difference in weightloss between a 400 cal VLCD, and one of 800cals. There should be a difference of 0.4 kg/week, so it's likely that this is due to people on 800cals being more likely to stick to it.
Weightloss on any VLCD is likely to be around 2kg/week for the first six weeks (nearly 4.5lbs) and then only 0.8kgs / week (2lbs) thereafter. again, this may be due in part to people not sticking to the diet.
any and all VLCDs will result in about 25% of lean muscle mass being lost. so every kg down is 250g muscle, 750g fat. This is percieved as being acceptable. Exercise has minimal impact in stopping this happening.
Most people who lose weight on any diet will regain it, but the data is flawed and incomplete. what the data does suggest is that a VLCD in combination with a follow-up programme of behavioural therapy, nutritional education and physical activity actually ranks quite highly in terms of long-term maintenance. Higher than some conventional diets.
Anyway - found it interesting and thought i'd share.
