CAN SUPPLEMENTS BURN AS MUCH FAT AS EXERCISE?
A blackcurrant-extract supplement can burn as much fat as four weeks of regular exercise, research suggested in May 2018.
When taken twice a day for just one week, the vitamin increases fat burning by an average of 27 per cent, with one study participant achieving a rise of 55 per cent.
Known as CurraNZ, the supplement is made from New Zealand blackcurrants and costs £21.75 for a pack of 30.
The berries contain nutrients, called polyphenols, which are thought to encourage fat burning during exercise by increasing blood flow, according to the researchers.
Study author Dr Sam Shepherd, from Liverpool John Moores University, said: 'Seven days is not a very long time to see such big changes.
'Anything above 20 per cent is typically what we expect to see with three-to-four weeks of regular endurance exercise training.'
This follows previous research that found the same supplement increases fat burning by around 21 per cent in active men.
Dr Shepherd said: 'It was positive to see that the effects of blackcurrants on fat burning extend to females, especially since women already have a greater reliance on fat as a fuel compared to men.'
The researchers believe their findings may also benefit people with obesity or type 2 diabetes.
Dr Shepherd said: 'Unhealthy people have a reduced capacity for fat burning compared to healthy people and therefore, in theory, the supplement could potentially exert at least a similar or greater effect in unhealthy individuals.'
