His name was Fleming, and he was a poor Scottish farmer. One day, while trying to eke（补充） out a living for his family, he heard a cry for help coming from a nearby bog (沼泽地). He dropped his tools and ran to the bog. There, mired（陷于泥坑）to his waist in black muck（淤泥） was a terrified boy, screaming and struggling to free himself. Farmer Fleming saved the lad from what could have been a slow and terrifying death.

The next day, a fancy carriage pulled up to the Scotsman's sparse(稀疏的) surroundings. An elegantly dressed nobleman stepped out and introduced himself as the father of the boy Farmer Fleming had saved.

"I want to repay you," said the nobleman. "You saved my son's life."

"No, " the Scottish farmer replied, waving off the offer. At that moment, the farmer's own son came to the door of the family hovel（茅舍）.

"Is that your son?" the nobleman asked. "Yes," the farmer replied proudly.

"I'll make you a deal. Let me take him and give him a good education. If the lad is anything like his father, he'll grow to a man you can be proud of."

And that he did. In time, Farmer Fleming's son graduated from St. Mary's Hospital Medical School in London, and went on to become known throughout the world as the noted Sir Alexander Fleming, the discoverer of Penicillin.

Obviously, most people who try to lose weight generally focus all or most of their attention on the food they eat. But what about their behavior? Are there habits they could be breaking that would also help them lose weight?

According to the Ohio State University Extension, which summarized the findings, the researchers learned people who routinely ate breakfasts, lunches, and dinners tended to have more success losing weight than people whose eating schedules were irregular. As a bonus, they were also more likely to eat a larger quantity of fruits and vegetables.

One activity that brought a disaster to people who wanted to lose weight was watching television, particularly if they ate while watching TV--especially if they ate while watching TV after 7 p.m. People who did these things, including simply watching a lot of television, tended to have a higher body mass index (BMI), as well as a higher intake of fat and sugars.

Those who ate out a lot also tended to take in more fat and sugars, while eating fewer fruits and vegetables. For the purposes of the study, eating away from home was defined not only as eating in restaurants but also eating food provided by an employer or colleagues at work, buying food at convenience stores or gas stations, or buying food for fund-raisers.

Finally, the best results were achieved by those motivated people who kept writing the track of the amount and type of exercise they did and how many calories they ate, who planned meals, and used meal replacements. Those who did these things the most generally lost more weight, ate less fat and sugars, ate more fruits and vegetables, and engaged in more physical activities.

So cutting out all those high-calorie snacks will help you lose weight. If so, apparently, will change some of your habits and behavior.
