BCAAs may be beneficial when cutting, as they can help preserve muscle mass while you are in a calorie deficit. When you are cutting, you are consuming fewer calories than your body needs, which can cause your body to break down muscle tissue for energy. By supplementing with BCAAs, you can provide your body with the essential amino acids it needs to prevent muscle breakdown and support muscle growth.
It is recommended to take BCAAs before or during your workout while cutting to help support muscle growth and recovery. However, it is important to note that while BCAAs can be helpful, they are not a magic solution for fat loss. In order to lose fat, you need to be in a calorie deficit and follow a balanced diet and exercise routine.
