I'm going to use drastic measures to lose weight.
What kind of drastic measures are you willing to take
I'm going to diet very aggressively.
Dieting is good, but dieting aggressively can be dangerous. There are no shortcuts to losing weight, it just takes time.
What are you a doctor?
I am not a doctor, but I know about weight loss. Diets take time to show results, trying to get them fast will end up with you messing up your body somehow.
