Weight loss is most simply put burning more calories than your body takes in during a day. So unless the process by which it happens involves a great deal of movement and sweating, probably not.
There is no any problem or abnormality for a 5'6 male to weigh 160 pounds.
You're within a healthy weight range, so you don't need to lose any more, but in order to maintain a healthy weight, don't fall below a weight of 112 pounds.
112 pounds is a good weight for a 5' 6" 18-year old male. They should not lose much more weight than this.
a 75 years old man is like a concrete block, once its set , there is no lose ends.(calories)
This depends on what your weight is now. But, it is important to have body fat. Women have more fat than male. Losing weight isn't always good, it is important you are only losing the fat.
It is unhealthy for any person to try to lose 30 pounds in one month. They can try to lose weight by eating healthier foods, restricting their calorie intake, drinking more water and exercising more often.
That depends on the age of the male, whether they are a child or an adult, and whether they need to lose weight, maintain weight, or gain weight. For in-depth information and examples, see the page link, listed in the Related Questions section, further down this page.
