The US researchers studied the link between body fat and intelligence. They have found less muscle more body may affect how flexible human thinking gets with age, possibly due to alterations in parts of the immune system. The study covering a huge sample of 4000 middle aged to older UK Biobank participants - both men and women, published in the ''Journal Brain, Behavior and Immunity''. The team studied the measurements of lean muscle mass, abdominal fat and subcutaneous and how they were related to changes in fluid intelligence over six years. The discovered that those in their mid 40s and 50s with high amount of fat in their mid-section had worse fluid intelligence as they grew older.
Way back in the past the research, conducted by French scientists over a period of five years, covering more than 2,200 adults claimed to have found a link between obesity and a decline in a person's cognitive function (Journal of Neurology, October, 2006). The researcher concluded that people with a Body Mass Index (BMI)– a measure of body fat – of 20 or less could recall 56 per cent of words in a vocabulary test, while those who were obese, with a BMI of 30 or higher, could remember only 44 per cent.
Scientists say, ''The greater your weight, the lower your IQ''. Obesity causes intellectual decline in the first half of the life course and may persist after that period.
Regular physical exercise is a good bet to control weight problem. In the case of women who have less muscle mass than men, resistance training is a must, researchers concluded. As mush as possible avoid fast food, food loaded with fat. Say no no to carbonated drinks with high sugar content or artificial sweeteners available on the market. Do nor ever develop sedentary habits. While working take a break every one hour and walk briefly. Between meals, avoid munching snacks. More importantly eat less at night to avoid adding more calories to your body.
