Does my weightloss plan sound ok or does it need some tweaking? Personal Trainers?

I am a 5'10'' 225lb female looking to lose about 40 lbs within a year.

I just started back to the gym and eating better.

I go to the gym at 5:30am everyday during the week and around 9am on Saturday. Sundays are usually a rest day, but I do sometimes go to the gym on Sundays.

At the gym I always do 30 minutes on the elliptical or crosstrainer and my heart rate is right in the middle of the fat burn level and cardio level.

Then I stretch for 5 minutes and do about 100 crunches.

Next I do 20 minutes of light weights with high reps alternating each muscle group each day (arms, legs, and then shoulders/chest).

I do a small amount of ab workouts everyday.

For my food plan, I joined caloriecounter and record everything I eat. The website says to eat about 1700 calories a day which I usually achieve or go right under. I am eating more protein and carbs but staying away from sugar.

I also started drinking at least 64oz of water a day and taking a multivitamin everyday.

What do you think of my plan? Does anything need to be changed or added?

How long do you think it will take to lose the 40lbs?

Thanks ahead of time.
