【BBC News】科学家发现,每天吃两顿饭(仅早餐和午餐,富含蔬菜、水果和纤维)的2型糖尿病患者,在血糖控制水平上优于少量多餐者(每天6顿饭)。此研究可能也适用于无糖尿病的想减肥者。不过仍需大型和随访时间更长的临床研究证实,不好随便套用哦。这项研究一共54人参加,分成两组,每组各27人,历时三个月(12个星期)。
 

Two meals a day 'effective' to treat type 2 diabetes

Only eating breakfast and lunch may be more effective at managing type 2 diabetes than eating smaller, more regular meals, scientists say.

Researchers in Prague fed two groups of 27 people the same calorie diet spread over two or six meals a day.

They found volunteers who ate two meals a day lost more weight than those who ate six, and their blood sugar dropped.

Experts said the study supported "existing evidence" that fewer, larger meals were the way forward.

Only eating breakfast and lunch may be more effective at managing type 2 diabetes than eating smaller, more regular meals, scientists say.

Researchers in Prague fed two groups of 27 people the same calorie diet spread over two or six meals a day.

They found volunteers who ate two meals a day lost more weight than those who ate six, and their blood sugar dropped.

Experts said the study supported "existing evidence" that fewer, larger meals were the way forward.

Timing important?

Type 2 diabetes occurs when the body does not produce enough of the hormone insulin to function properly, or the body's cells don't react to insulin.

Since insulin controls the amount of sugar in the blood, this means blood sugar levels become too high.

If untreated, it can lead to heart disease and stroke, nerve damage, light-sensitive eyes and kidney disease.

About 2.9 million people in the UK are affected by diabetes, 90% of whom have the type 2 form of the disease.

Current advice in the UK recommends three meals a day, with healthy snacks.

Scientists at the Institute for Clinical and Experimental Medicine in Prague divided a group of 54 volunteers aged 30 to 70 with type 2 diabetes into two groups of 27 people.

Volunteers were then given either a six-meal-a-day diet (A6) for 12 weeks followed by a two-meal day diet (B2), or vice versa.

The study compared two meals with six meals - as the latter accorded with current practice advice in the Czech Republic, researchers said.

Each diet contained on average 1,700 calories a day.

'Very pleasing' result

The B2 group ate between 06:00 and 10:00 and then between 12:00 and 16:00, and the A6 group ate their food throughout the day.

Weight loss for the B2 group averaged 1.4kg (3lb) more than A6, and they lost about 4cm (1.5in) more from their waistlines.

Lead scientist Dr Hana Kahleova, at the Institute for Clinical and Experimental Medicine, said the results were "very pleasing".

She said: "The patients were really afraid they would get hungry in the evening but feelings of hunger were lower as the patients ate until they were satisfied.

"But when they ate six times a day the meals were not leaving them feeling satisfied. It was quite surprising."

'Larger studies needed'

Dr Kahleova said the study could apply to people without diabetes who were trying to lose weight.

Dr Richard Elliott, research communications officer at Diabetes UK, said the study added to evidence that eating fewer, larger meals a day could be more effective than smaller, frequent meals at helping people manage their condition.

He added: "However, larger studies over longer periods of time will be needed to back up these findings before we would make changes to the dietary advice given to people with type 2 diabetes."

Dr Elliot said eating a healthy, balanced diet, being active and maintaining a healthy weight, alongside taking any medication was "vital" to effectively manage the condition.
