Greenlane Diet

 By Mizpah Matus B.Hlth.Sc(Hons)

The Greenlane Diet is a poor fad diet that has been circulating for many years.

Please note no medical association or hospital (Greenlane Hospital in Auckland) has nothing to do with this diet whatsoever.

The diet has circulated in the form of a one page sheet that claims you can lose 10 pounds in 3 days. The diet has been popular in the UK – but it’s exact origins are unknown.

Interestingly, the diet bears a striking resemblance to the Scarsdale diet – also written in the 1970s.

Greenlane Diet Plan

The Greenlane diet is a very low calorie diet – a typical day’s eating culminates in only 700 calories. This is a crash diet – a sudden and severe reduction in calories that results in primarily fluid loss.

The diet should never be undertaken for more than 3 days, any longer and your body will immediately slow down metabolism and place you on target for yo-yo dieting (and subsequent weight gain).

The Greenlane Hospital diet contains a small selection of foods; Dry toast, fruit, tuna, ‘snax’ biscuits. Snax biscuits are a cracker made by the food brand Griffins in New Zealand indicating that this diet may have originated from this part of the world (which does have a Greenlane hospital in Auckland). However this cannot be verified.

Fad Diets Never Work Long-term

VLCD diets like the Greenlane Diet never produce long-term results unless people begin a calorie reduced, long-term eating plan after the 3 day diet has finished.

Also these diet tend to promote unhealthy eating patterns and can result in eating disorders. We advise dieters to find plans that are sensible, healthy, and nutritionally adequate with slow and steady weight loss as a goal.
