Women's breasts are mainly made up of fat. When you do a lot of exercise, you will burn fat in your body, and fat burning is a systemic change (so there is no such thing as local fat burning), which naturally includes burning fat in your chest.
Is there a contradiction between weight loss and breast preservation?
Keeping the intake and consumption of calories in a balanced state can keep the chest from shrinking at all, but after the calories are balanced, your fat-reducing effect will be greatly reduced. Therefore, there is indeed a certain contradiction between "breast preservation" and "full fat reduction".
Is there any way to save the chest?
Do strength training! The breast is attached to the pectoral muscle, which changes the sagging and ugly chest shape and gives strong support to the chest.
Practicing the pectoral muscles in the lower part of the breast will naturally raise the chest and make the chest more compact and beautiful. It will look better than a huge but drooping chest.
Judging from the body fat rate, you don't have to worry too much about losing some fat, but your chest is getting tighter.
Body fat content has not dropped, why is the chest small?
Chest sagging is also the reason why the chest becomes smaller. If the fitness frequency is intense, the chest is easy to get hurt.
Take running for example. The violent swing of the chest will damage the elastic fiber tissue of the chest, leading to contraction, sagging and deformation of the chest. When doing this kind of exercise, you must take measures to protect your chest and choose a sports bra with good breathability and strong fixation.
To sum up, strength training is the key to prevent chest contraction. Girls, try it!
