You are important to yourself, therefore, it is essential that you take time to look after your health and physical body. Eat correctly and set sufficient time aside each week, for physical exercise and relaxation. As you will require time to alter your life; your physical body will also continue to alter during this period.
Slow change is good change and is of greater benefit to you, in the long term. This is especially true for an individual that is overweight, as sudden weight loss creates more harm than good.
