A body budget is our body/mind/brain capacity to cope. Building a healthy body budget includes common sense practices such as eating well, maintaining a healthy weight and fitness level and taking time for relaxation. Body budgeting will lead to the regulation of personal affect, better understanding and control of emotion concepts, and improvement of emotional literacy and granularity.
Historically, I have body budgeted without knowing the actual term and it has led to an exceptional understanding of my current state of being in which I am hyper aware of (and at peace with) any interoception going on.
