Developed by nutritionist Barbara Rolls in 2000, Volumetrics advocates eating more, not less. The idea is that foods with high water content, such as soup and salad, make you feel fuller and less deprived.
The Daily Beast found the plan most effective for both short and long-term weight-loss, heart health and diabetes control.
Eat more, not less: The Volumetrics regime, which prescribes plenty of foods with high water content such as soup, salad and low-starch vegetables, has topped a major ranking of diets
The hugely-popular WeightWatchers and Jenny Craig diets came in second and third place respectively, with the vegan diet and low-carb Atkins regime also placing high.
Also on the list, possibly indicating a comeback, was the Slim Fast plan, which last saw its popularity peak in the Nineties.
The 'shake for breakfast, shake for lunch, and a sensible dinner' concept, first launched in the late Seventies, delivers on its weight-loss promise, The Daily Beast found, and is good for diabetes control, though data was 'inconclusive' as far as heart health is concerned.
Surprise entry: Could Nineties favorite Slim Fast be due a revival?
'We ranked diets based on the most recent published clinical data on long-term and short-term weight loss (as evidenced by 6-month and 12-month weight loss),' The Daily Beast's Lauren Streib wrote.
'This year we also included a 5-point scale for promoting cardiovascular health and controlling diabetes based on available published research, which affected the rankings.'
Diets at the lower end of the scale fell short on heart health and diabetes control.
The Paleolithic diet, for example, which mimics the meat, nut and vegetable-heavy diet of cavemen, cuts all processed food including grains and dairy.
But while it may be the most effective for maintained weight-loss, the research indicates that it is not the best option for heart health or diabetics.
It is a similar story with the Glycemic Index and Atkins diets, which can be effective for weight-loss but not for heart health.
As Streib says of the GI diet: 'Foods that are composed of nearly all protein and fat aren’t really addressed in the diet, since they have no GI value, so the plan can be a hard to follow and assess nutritionally.'
