Body weight - person's mass or weight. Body weight is measured in kilograms, pounds, or stones and pounds. Body weight is the measurement of weight without items located on the person.
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health.
People are generally considered obese when their body mass index (BMI) is over 30 kg/m2, with the range 25–30 kg/m2 - overweight.
BMI, body mass index - a measurement obtained by dividing a person's weight by the square of the person's height.
Obesity increases the likelihood of diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
Obesity is most commonly caused by a combination of excessive food intake, low levels of physical activity, and genetic susceptibility. A few cases are caused primarily by genes, endocrine disorders, medications, or mental illness. Evidence to support the view that obese people eat little yet gain weight due to a slow metabolism is not generally supported.
On average, obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass.
Fructose and glucose are simple sugars, monosaccharides, with the general formula C6H12O6.
Fructose, or fruit sugar, occurs naturally in fruits, some root vegetables, cane sugar and honey and is the sweetest of the sugars.
Glucose, dextrose or grape sugar, occurs naturally in fruits and plant juices and is the primary product of photosynthesis. Most ingested carbohydrates are converted into glucose during digestion and it is the form of sugar that is transported around the bodies of animals in the bloodstream.
Sucrose is a compound sugar, disaccharide, with the general formula C12H22O11. Sucrose is found in the stems of sugarcane and roots of sugar beet. It also occurs naturally alongside fructose and glucose in other plants, in particular fruits and some roots (carrots). A molecule of sucrose is formed by the combination of a molecule of glucose with a molecule of fructose, and it is split into these parts during digestion.
The different proportions of sugars found in plant foods determines their sweetness.
