It is no secret that obesity and overweight lead to serious diseases.. They increase the risk of coronary heart disease, type 2 diabetes, hypertension, cancer, stroke, sleep apnea, breathing problems and other diseases, reports Science World Report. However, not much is known about how a small weight gain (2-5 kilograms) affects the health.

A team of researchers from the American Heart Association found: healthy young people who have gained about two kilograms, increase blood pressure. Scientists have been watching people between the ages of 18 and 48 for 8 weeks. At the beginning of the study, participants were measured for blood pressure.. After 16 volunteers had to consume 400-1200 calories more than usual, so that their weight increased by 5%. The researchers then measured the blood pressure of the participants again and compared it with the pressure of 10 healthy people of normal weight.. The body weight of these people for 8 weeks did not change.

In volunteers who gained weight, systolic blood pressure increased from an average of 114 to 118 millimeters of mercury.. For participants whose body fat accumulated on their stomachs, the increase in blood pressure was most noticeable.. However, this weight gain did not affect cholesterol, insulin and blood sugar levels.. Researchers believe: people need to be warned of the dangers of a few extra pounds, because many are gaining weight during the holiday season or the first year of university.
