It’s official. Low energy total diet replacements work.
These are the very low calorie diets (VLCDs) where you replace all food for a short period of time with specially formulated soups, shakes and bars. Add in 750ml of skimmed milk, 2.25 litres of water or other low or no energy drinks and a fibre supplement and the total 810 kcal/day meets all your nutritional requirements.
These have been around some thirty years, I hear you say. Why the big fuss now?
Basically everyone’s talking about the results of the DROPLET trial (‘doctor referral of overweight people to low energy total diet replacement Treatment’), published in late September 2018 in the BMJ (1).
The study compared weight loss results from 278 overweight adults in Oxfordshire randomly trialling two methods. One group used a total diet replacement programme (TDR), the other used the ‘usual care’ offered by GP practices for people wanting to lose weight.
Both programmes included behavioural support, the first provided by the commercial company offering the TDRs, Cambridge Weight Plan UK, and the other provided by practice nurses.
The researchers not only found that people on the TDR lost more weight:
· The TDR group lost, on average, 10.7kg
· The ‘usual care’ group lost 3.1kg.
They also found they kept more of it off in the longer term. Twelve months on 10% or more weight had been lost by:
· 45% of the TDR group
· 15% of the ‘usual care’ group.
Now this doesn’t mean that people stayed on the TDR programme all that time. The TDR was only followed for 8 weeks, then normal food was reintroduced. From months 3 to 6 people were supported with weight maintenance.
One of the most interesting things about this trial and the report is that, not only is it reported in the BMJ, it very clearly indicates that all such diets offered are effective. If you’re not quite there yet, have a look at these direct quotes from the report:
“Referral to a total diet replacement programme with support provided by a commercial provider is an effective intervention for the routine treatment of obesity.”
“A TDR programme combining nutritionally complete formula food products with behavioural support seems to be acceptable, well tolerated, and leads to greater weight loss with larger improvements in cardiovascular risk than currently available weight loss programmes offered in primary care.”
