Ginger – can it increase satiety?
This evidence formed the impetus for a 2012 pilot study published in the journal Metabolism that assessed the effects of a hot ginger beverage on energy expenditure, feelings of appetite and satiety and metabolic risk factors in overweight men.
The study showed that overweight men who incorporated a ginger drink into their morning meals had a lower prospective food intake later in the day and reduced hunger. The findings suggest ginger may play a potential role in overall weight management by increasing satiety without any adverse side effects.
Scientists from Columbia University and the New York Obesity Research Centre gave 10 overweight but otherwise healthy men a standard breakfast accompanied by a ginger “tea” containing 2 grams of dried ginger powder (about 1 teaspoon) or the same breakfast with plain hot water on two separate days. Researchers documented feelings of hunger before and hourly after breakfast consumption, the calories burned after eating (thermic effect of food) as well as other measures.
They found approximately 43 more calories were burned after eating but total resting energy expenditure and respiratory quotient were not significantly affected. There were also no ginger-related effects on blood glucose, insulin, triglycerides or a variety of other metabolic parameters.
The results, showing enhanced thermogenesis and reduced feelings of hunger with ginger consumption, suggest a potential role of ginger in weight management. Additional studies are necessary to confirm these findings.
While more research is needed to understand the role of ginger in weight management, the researchers concluded that by including powdered ginger in the diet it could have a small but significant effect on how food is processed in the body and “influence feelings of satiety without any adverse side effects.”
