text: how long will it take to lose 40 pounds? i've started biking about 6 miles at least four times a week. i don't eat really healthy. my parents usually order out, like chinese or pizza, but i want to change that, so does anyone know any diets or sites with low fat recipes? thanks. try checking out your local library for some fitness info.  the web can be something of a challenge.  you might find a fitness magazine you like & see if they have a web-site.  you can safely use about 1-2 pounds a week, but really need to fix the diet issue.  you don't talk about what you drink - so, no soda, no sugary drinks.  drink plenty of water to stay hydrated.  ditch the chinese (sauces can be really bad) and use the pizza as an occassional treat (1-2 pieces only).  do eat as many veggies & fruits as you can.  whole grain breads.  lean meats, like chicken (no skin, not deep fried).  read labels!  know what's in your food!  good luck!
