Very low calorie diets do not produce greater long-term weight loss

Very-low-calorie diets produce greater short-term weight loss, but do not produce greater long-term weight loss than low-calorie diets according to an analysis from researchers from the University of Pennsylvania School of Medicine in Philadelphia, Pennsylvania. Short-Term Weight Loss
Short-term weight loss: 16% vs 10%
Very-low-calorie diets produced an average short-term weight loss of 16.1 percent compared to 9.7 percent with a low-calorie diet.
Long-Term Weight Loss
Long-term weight loss: 6% vs 5%
However, long-term weight loss was similar between the two, with very-low-calorie diets causing an average long-term weight loss of 6.3 percent compared to 5 percent for low-calorie diets.
They also noted that the drop-out rates was similar for the two types of diets.
Meal Replacement Shakes
Meal Replacement Shakes instead of very-low-calorie diets
Also of interest, they note that “the use of liquid meal replacements as part of a 1000 to 1500 [calorie per day] diet may provide an effective and less expensive alternative to [very-low-calorie diets].”
The research does show that meal replacement shakes are very effective.
A couple of weight loss doctors have told me that they find them very helpful for helping patients break through weight plauteaus.
