To lose fat effectively, you first need to increase your protein intake and decrease carbs and then jog or run on the tread mile every morning at a constant speed. Try drinking 1 to 2 glasses of lime or lemon water every day, and perform light weight training. Find out more details on http://www.ehow.com/how_2047971_lose-fat-fast.html.
First, you need to know that realistically, you should only lose 2 pounds a week with a healthy program. Second, from what I've heard, men love women. Period. Some like thin, some like curvy. Some like tan, others like pale. Be yourself.
Crash dieting is okay if it is ONLY for a week. Just know your limits because I did that and now I have an eating disorder. (the only reason why I am promotin a crash diet is because my friends did that for prom and stuff, but they stopped and know their limits, so of you are a person who likes to stick to rituals, don't do it!)
