It may help in fighting fat.


Scientists have revealed that exercising right after eating a meal high in fat content may help people keep in shape. Max Lafontan and his team examined how fat breaks down in both lean and obese individuals who exercised after either fasting or eating a high-fat diet. They found that when either a lean person or an obese individual exercises after having a meal of high fat content, their fats break down and get oxidised in the skeletal muscle, which makes them healthier.

Work that meal out

The researchers observed that fats break down both in lean and obese individuals, after eating a high-fat diet. Whereas, under fasting conditions, the breakdown was more prominent in the lean subjects, but the high fat meal improved lipolysis, a process in which fat is broken down inside fat cells to generate energy, in the obese subjects.

For the first time, these results show how stimulation of the breakdown of fats occurs after having a high fat diet and exercise. They may also help design ways to reduce excessive fat in the body. After the process of lipolysis, the resulting fatty acids get released into the bloodstream and are carried to tissues that require energy. In obese individuals, accumulation of fat is too much, compromising lipolysis, but how this happens are still not well understood. Also, such individuals show altered responsiveness to the stress hormones epinephrine and norepinephrine in their subcutaneous fat.

The scientists also studied the effects on cultured fat cells by long-chain fatty acids (LCFAs). They observed that LCFAs cause an increase in lipolysis when induced by one of the hormones known to stimulate lipolysis, epinephrine. The researchers concluded that by showing the affects of a high fat diet and LCFAs on hormone-induced lipolysis in fat cells, the study lays the foundation for further research on the role played by various fatty acids on the metabolism of muscle and blood vessel cells.

The Wonders of Olive Oil!

Myriad benefits of Olive oil.
Moderate amounts of olive oil will also reduce abdominal fat

An olive-oil-rich diet is not only a good alternative in the treatment of diabetes, but also helps in preventing or delaying the onset of the disease.

Obesity and abdominal fat:
Olive oil is high in calories like any other fats and oils, but the research states that, there is less obesity amongst the Mediterranean peoples, who consume the most of olive oil. Olive-oil- rich diet helps in greater and long lasting weight loss than a low- fat- diet. Moderate amounts of olive oil will also reduce abdominal fat, if eaten as part of a diet high in plant foods.

Olive oil plays a key role in foetal development during pregnancy. If women consume olive oil during pregnancy, they give birth to children better in terms of height, weight behaviour and psychomotor reflexes.

Olive oil plays an important role in the prevention of continuous oxidation, one of the processes that influences the development of certain types of skin cancer.

Natural painkiller:
Good quality olive oil contains a natural chemical that acts like a painkiller. 50g of extra-virgin olive oil was equivalent to about a tenth of a dose of ibuprofen.

A mono unsaturated fatty acid called Oleic acid has significant protective effects against cancer. It has the ability to reduce the affect of an oncogene, a gene that will turn a host cell into a cancer cell. It can even help to fight breast cancer.

Other benefits:
It maintains metabolism and contributes to the development of the brain and bones in children. It is also recommended as a source of vitamin E for older people.

Olive oil also acts like a natural anti-oxidant, that slows down the natural aging process. It also slows down acid overproduction in the digestive system thereby diminishing the potential for ulcers and other gastrointestinal problems.
