|Obesity is a medical situation in which excess body fat has stored to the extent that it may have a negative effect on health, leading to reduced life expectancy and/or increased health problems. In Western countries, people are measured obese when their body mass index (BMI), a dimension obtained by splitting a person's weight by the square of the person's height, exceeds 30 kg/m2, with the range 25-30 kg/m2 defined as overweight. Some East Asian countries use stricter criteria.
Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
