Calorie free refers to a products with less than five calories per serving. A low calorie food has no more than 40 calories per serving.
Reduced calorie foods as having less calorie must have 25% fewer calories in the given amount than the food to which it is being compared.
Around 1930s, Dr. Kenneth Pelletier, did his longevity research and found that the cultures that highest longevity and created the healthiest people, such as in the Vilcabamban region in Ecuador, the Hunzas of West Pakistan, the Tarahumara Indians of Mexico and the Russian people of Abkhazian region. They ate significantly less total calories about 50% less than the typical American diet.
Scientists found signs according to which reducing calories may lead to a longer life. The study said cutting calories lowered insulin and mentioned that further studies were needed to confirm the findings.
Research indicates that people who eat less calorie food actually consume fewer calories throughout the entire day.
A lot of evidence already exists to suggest that calorie restriction increases maximum life span in several animal species. However, there hasn't been any proof of it being the case in humans. This is the first step toward looking at the beneficial effects of calorie restriction in humans.
Lower blood levels of insulin and a lower body temperature were also noticed at patients with a restricted calorie regime.
There are some studies in the literature that show that fat replacers pride health benefits to the public such as weight loss, reduction in cholesterol and lower incidence of cardiovascular disease.
It was reported that subjects consuming olestra (one of the fat replacers) had significantly reduced total serum cholesterol levels compared with subjects without consuming olestra.
Body temperature and blood insulin levels are markers of longevity like gray hair or wrinkles can be.
It has been shown both in animals and humans that those with lower body temperature tend to live longer, and so do those with lower fasting insulin levels.
