Fat also gives texture and flavor to foods. It helps us feel full and satisfied after we eat. In addition, it protects our organs, aids in the development of cell membranes and hormones, and insulates our bodies. Excess fat in our bodies is linked to health problems such as hardening of the arteries and heart disease, to name just two. Throughout a day, a month, a year, and even a lifetime, the body's supply of and demand for fat changes.
Demand increases with activity and decreases in sedentary times.
We can modify our caloric intake to meet these changing conditions. We can also manage the body' s fat supply through exercise, which uses fat as fuel. So, to maintain a healthy balance in our bodies, we need to monitor our food intake and energy demands and add a daily dose of exercise. Down the hatch.
