Eating Fast Makes You Fat

Just out from the British Medical Journal; Eating until you feel full and eating fast are associated with being overweight.

Obesity has become a worldwide problem in developed countries and the highest selling books are cookbooks and diet books. Obesity is an important risk factor for cancer, cardiovascular diseases and diabetes. This study gives us more evidence on how we can help people with weight control.

The researchers studied 4140 Japanese adults and measured their body mass index. They used a validated survey to assess speed of eating (very slow, slow, medium, fast, very fast) and they also asked about eating until full.

They found that for both sexes, those that reported eating until full and eating quickly had the highest age adjusted values for weight, body mass index and total energy intake. They further adjusted for total fibre intake, alcohol, smoking and physical activity and still found that eating quickly made you fatter. For patients who both ate quickly and ate until full there was a "supra-additive" effect on being overweight.

With all of the diets around and advice given to help people lose weight, just having them chew their food more slowly would help. Remember what grandma used to say "Quit gobbling your food. Sit there and chew". She was right. Grandma also said " Stop gorging. You're not a pig" Well, right again.

Grandma's wisdom and the British Medical Journal have the last word: Portion size and small plates are known to be effective weight controls.

Hmmm. Perhaps for some it means they should eat food they really don't like. They might eat it slower. I know when I eat something delicious I must resist the urge to snaffle it down.

I always believe in moderation when it comes to anything especially eating.

There is a 20 minute delay in the brain telling the body that the stomach is full. As food journalist Michael Pollan once pointed out, Europeans engage in "relaxing" meal conversations so they end up eating less while their American counterparts are always in hurry, gorging lots of foods down their throats that by the time their brains tell them that they are full, they don't realize they've overeaten.

I have seen a lot of slow eating French, Italian , Spanish people having a long conversation while eating and they were as fat as the one I find here in the US . Some eat like horses and stay slim , others eat like birds and gain weight.
One good thing about this article , it may change the habit of stuffing the food and minutes later wondering what was it what we had for dinner .....

Hmm very interesting read. I am very guilty of eating too quickly, especially lately. Hopefully I don't begin to see the results.

The Potential Results Of Obesity

Obesity has been defined as when excess body fat accumulates in one to where their physical overgrowth makes the person unhealthy to varying degrees. Obesity is different than being overweight, as others determine obesity to be of a more serious concern. While obesity is not a disease, it is a serious health risk for one who has this risk.
As measured by one’s body mass index (BMI), one’s BMI of 25 to 30 kg/m is considered overweight. If their BMI is 30 to 35 kg/m, they are class I obese, 35 to 40 BMI would be class II obese, and any BMI above 40 is class III obesity.
Presently, with obesity affecting children progressively more, the issue of obesity has become a serious public health concern. In the United States, greater than one third of all citizens are obese, and this number continues to progress.
Approximately half of all children under the age of 12 are either obese are overweight. About twenty percent of children ages 2 to 5 years old are either obese are overweight. The consequences of these stats on our children are very concerning, considering the health issues they may or likely experience as they get older.
Worldwide, nearly one and a half billion people are either obese or overweight. In the United States, about one third of adults are either obese or overweight.
Women of low socioeconomic status are likely to be twice as obese compared with those who are not at this status. It is now predicted that, for the first time in about 150 years, our life expectancy is suppose to decline because primarily of this obesity problem.
Morbid obesity is defined as one who has a body mass index of 30 kg/m or greater, and this surgery, along with the three other types of surgery for morbid obesity, should be considered a last resort after all other methods to reduce the patient’s weight have chronically failed.
Morbid obesity greatly affects the health of the patient in a very negative way. It has about 10 co-morbidities that can develop if the situation is not corrected. Some if not most of these co-morbidities are life-threatening.
One solution beneficial in many cases of morbid obesity if one’s obesity is not eventually controlled or corrected is what is known as gastric bypass surgery. This is a type of bariatric surgery that essentially reduces the volume of the human stomach in order to correct and treat morbid obesity by surgical re-construction of the stomach and small intestine.
Patients for such surgeries are those with a BMI of greater than 40, or a BMI greater than 35 if the patient has co-morbidities aside from obesity. This surgery should be considered for the severely obese when other treatment options have failed. The standard of care illustrating as to whether this surgery is reasonable and necessary should be clarified.
There are three surgical variations of gastric bypass surgery, and one is chosen by the surgeon based on their experience and success from the variation they will utilize. Generally, these surgeries are procedures related to gastric restrictive operations or mal-absorptive operations.
Over 200,000 gastric bypass surgeries are performed each year, and this surgery being performed continues to progress as a suitable option for the morbidly obese. There is evidence that this surgery is particularly beneficial for those obese patients that have non-insulin dependent Diabetes Mellitus as well.
It is believed that the results of this surgery to correct morbid obesity greatly limits or prevents such co-morbidities associated with those who are obese. Yet about two percent of those who undergo this surgery die as a result from about a half a dozen complications that could occur. However, the surgery reduces the overall mortality of the patient by 40 percent or so, yet this percentage is debatable due to conflicting clinical studies at times.
Age of the patient should be taken into consideration, as to whether or not the risks of this surgery outweigh any potential benefits for the patient who may have existing co-morbidities that have already caused physiological damage to the patient. Also what should be determined by the surgeon is the amount of safety, effectiveness, and rationale for a particular patient regarding those patients who are elderly, for example.
Many feel bariatric surgery such as this should be considered as a last resort when exercise and diet have failed for a great length of time.
If a person or a doctor is considering this type of surgery, there is a website dedicated to bariatric surgery, which is:,

I've been reading this blog and I think you are posting an important issue because traditional diets vary with availability of local resources, such as fish in coastal towns, eels and eggs in estuary settlements, or squash, corn and beans in farming towns, as well as with cultural and religious customs and taboos.
