The normal range of body fat rate for normal adult women is between 16% and 27%, so 30% body fat rate for women means that it exceeds the normal range of body fat rate and belongs to the state of higher body fat rate. Body fat rate is an important indicator to judge obesity, if the body fat is too high and the weight exceeds the normal value (body fat rate of 20%), it can be regarded as obese. A body fat rate of 30% is slightly higher than the normal range, and it is easy to lose shape and also increases the risk of atherosclerosis, coronary heart disease, diabetes, hypertension, hyperlipidemia and other diseases. It is recommended that you keep your body fat percentage in the normal range and avoid having a body fat percentage that is too high or too low. With a body fat percentage of 30%, it is recommended to adjust the diet structure and change lifestyle habits. You should consume more fresh vegetables and fruits and avoid foods that contain more calories, sugar and fat, such as fried chicken, chocolate, milk tea and barbecue. Also perform proper exercise to promote metabolism and help reduce body fat rate. If obesity is caused by endocrine diseases and a body fat rate of 30% occurs, the primary disease should be treated under the guidance of a professional doctor. After treating the primary disease, then adjust the diet and carry out appropriate exercise to make the body fat rate decrease.
