A cup of coffee a day could help to shed the pounds, study suggests

Drinking a cup of coffee a day could help beat obesity, according to the first major human trials.

Scientists have found that coffee can stimulate “brown fat” - which plays a key role in how quickly calories are burned off.

Brown adipose tissue, also known as brown fat, is one of two types of fat found in humans and other mammals.

Its main function is to generate body heat by burning calories - unlike white fat, which is a result of storing excess calories.

People with a lower body mass index tend to have a higher amount of brown fat, experts say.

The study by Nottingham University researchers, published in the journal Scientific Reports, follows a series of studies which have found such a link in animals.

Study co-director Professor Michael Symonds said: "Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold.

"Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss.

"However, until now, no one has found an acceptable way to stimulate its activity in humans.

"This is the first study in humans to show that something like a cup of coffee can have a direct effect on our brown fat functions.

"The potential implications of our results are pretty big, as obesity is a major health concern for society and we also have a growing diabetes epidemic and brown fat could potentially be part of the solution in tackling them."

The research team started with a series of stem cell studies to see if caffeine would stimulate brown fat.

Once they had found the right dose, they then moved on to humans to see if the results were similar.

The team used a thermal imaging technique, which they'd previously pioneered, to trace the body's brown fat reserves. The non-invasive technique helps the team to locate brown fat and assess its capacity to produce heat.

Prof Symonds added: "From our previous work, we knew that brown fat is mainly located in the neck region, so we were able to image someone straight after they had a drink to see if the brown fat got hotter.

"The results were positive and we now need to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there's another component helping with the activation of brown fat.
"We are currently looking at caffeine supplements to test whether the effect is similar.

"Once we have confirmed which component is responsible for this, it could potentially be used as part of a weight management regime or as part of glucose regulation programme to help prevent diabetes."

I hope it is the caffiene, because I don't drink much coffee (maybe once a month), but I drink vast quantities of black tea! :-)

Having long been a 1 to 2 cups/day morning coffee-drinker, I too hope they're on to something but...

So subjects drink coffee (most likely HOT coffee) and their neck regions get warmer and researchers immediately ascribe that effect as something in the coffee up-regulated the brown fat in subjects' necks???
Gotta wonder, was it the coffee or simply the heat from the warm drink? Hope they at least ran the experiment using a plain old hot water drink as a comparison control.

Caffeine antidote for blood sugar control and increased calorie burning due to metabolic responses is a nice, simple thought. Wim Hof has been researching and demonstrating methods to activate brown fat with positive metabolic responses for years. The caffeine approach for sedentary people or those who are physically limited to being sedentary bears further research; however, those who can move and are active have different options for increasing metabolism and improving health:

After baseline imaging, participants consumed either a caffeinated beverage (Nescafe© Original 1.8 g sachet ~65 mg caffeine dissolved in 200 ml water at 22 °C; n = 9) or water alone at 22 °C (n = 9), remained seated for 30 minutes (to allow time for caffeine absorption33) and then underwent further thermal imaging.


Yup. Hot water was the control.

Thanks Teaser, I didn't track down the original report, just read the Telegraph article. Good to know they ran the obvious control. There's hope for research science yet!

One of the benefits of eating keto for me is how I can have coffee again. It makes me feel good in the morning, pushes my first meal of the day into brunch/lunch territory, and yet I sleep okay at night.
