It looks like you are on the right track. You are right about cutting out the sweets and drinking more water but you are a little confused about eating less. The simple fact is, the less cals you consume, the slower your metabolism becomes. The simple way to solve this is eat every 2-3 hours. Every meal should include a good protein source, such as chicken, lean beef, eggs, whey, etc. Aim for around 35-40 grams of protein per meal. Also something else you need to include in your diet is healthy fats. THEY DO NOT MAKE YOU FAT! They have actually been shown to help you loose fat while saving muscle. Good sources of healthy fats are, natural peanut butter, notice I said natural, olive oil, olives, nuts, etc. Try getting a good size portion of complex carbs in the morning mixed with some simple carbs to give you a nice kick for the day. Have some simple carbs before you hit the gym, and then after you leave. A fat burner such as Xenadrine would also be good to take. You should be getting in about 6-7 meals a day. Do cardio 4-5 days a week, 35 min a time. You will loose weight by not eating, but I guarentee you will not like the results. If you follow the guidelines I set for you, you will improve dramaticlly. You might even gain some muscle!
