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.
A sharp distinction between humans and “animals” is essential if we are to bend them to our will, make them work for us, wear them, eat them–without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeeling toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.
Vitamins are a group of substances that are needed for normal cell function, growth, and development. There are 13 essential vitamins:
Vitamin A (retinol, retinal, 4 carotenoids)
Vitamin C (ascorbic acid)
Vitamin D (D3 - Cholecalciferol, D2 - Ergocalciferol)
Vitamin E (tocopherols, tocotrienols)
Vitamin K (phylloquinone, menaquinones)
Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
Vitamin B5 (pantothenic acid)
Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine)
Vitamin B7 (biotin)
Vitamin B9 (folic acid)
Vitamin B12 (cyanocobalamin)
Fat-soluble vitamins are stored in the body's fatty tissue: vitamins A, D, E, K.
Water-soluble vitamins - the body must use almost all water-soluble vitamins right away - vitamins B1, B2, B3, B5, B6, B7, B9 and C. Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.
