HIFU is being studied in men with prostate cancer. In 2015 the FDA authorized two HIFU devices for the ablation of prostate tissue. The treatment is administered through a transrectal probe and uses heat generated by focusing ultrasound waves to kill cancerous cells in the prostate.
How Many Calories for Breakfast. Many women who are trying to lose weight, consume about 1,200 to 1,400 calories per day. Men often consume 1,600 to 1,800 calories per day. Many people simply divide their calories evenly between three daily meals to keep their breakfast, lunch and dinner calories simple.
Dividing those numbers by three, the average woman should eat about 565 calories per meal, while the average man should eat about 735 calories per meal. If you eat more snacks, have smaller meals, and vice versa. These numbers work for weight maintenance; if you eat more calories than you burn, you'll gain weight.
