Fat turns into flab 3 hours after big meal
May 14th, 2012 - 5:39 pm ICT by IANSLondon, May 14 (IANS) An average person can virtually add two to three teaspoons of fat to his or her waistline in a matter of hours after eating. Fat from meals eaten later in the day is more likely to be stored around the middle.
The finding that it is possible to ‘become fat’ within three hours contradicts the widely-held belief that weight gain is gradual. It had been thought that fat from food was transported from the gut into the blood, where it could be used by the muscles as needed.
Any excess was thought to be slowly removed and stored in the fatty, or adipose, tissue around the waist, hips and legs. However, the Oxford University research suggests a more complex - and rapid - process, the Daily Mail reports.
In the experiments, volunteers ate fat which could be traced around the body. This was found to take around an hour to be broken down in the gut and then enter the bloodstream as tiny droplets.
The droplets are then whisked around the body - but not for long - before they are ‘caught’ and stored. “The process is very fast,” said Fredrik Karpe, professor of metabolic medicine at Oxford. “The cells in the adipose tissue around the waist catch the fat droplets as the blood carries them and incorporates them into the cells for storage.”
Only a small amount of the fat found in breakfast takes this route. But, by dinner, the amount rises to half. This is due to hormonal changes that occur later in the day which make it easier for the stores in the waistline to trap passing fat droplets. In a dinner with 0 grams of fat, two to three teaspoons will quickly gather around the waist.
The good news is the storage system is temporary, with the fat deposited quickly drawn on, or mobilised, to feed our muscles. But when we overeat, it is a different story, Karpe warns.
“If you eat too much, you don’t get into this phase of starting to mobilise it,” he said. ‘There will just be constant accumulation and you will start to put on weight,” concluded Karpe.
