I started my exercise program 2 weeks ago and it has been successful, but I am concerned that I lost 10 lbs in 2 weeks! (200lbs -->190lbs)

Age 21
Sex Male

Here is my nutrition plan:

Multivitamin

Breakfast:
* Bowl of Honey Nut Cheerios w/ skim milk
OR
* 2 egg whites with 1 slice of cinnamon raisin toast

Lunch:
* small Turkey sub with lettuce, onions, and american cheese on wheat bread
* Water

Snack:
Honey Nut Cheerios (no milk)

Dinner:
varies a lot

*Pasta, chicken, fish
* Water


The main thing about the diet is I really pay attention to portions and it seems to help a lot. Whenever I eat I am hungry but not starving. Before I use to eat 2-3 times more each day and ate a lot of pizza. (I am in college)


My exercise plan is pretty intense and have increased in intensity as my fitness has improved, it involves 2/3 cardio and 1/3 lifting 6 days a week.
(I take Fridays off)

* Stretch
* Run on a track 1.5 miles-3 miles (usually 2-3 miles now)
* Lift arms or legs depending on the day (I alternate each day)
* Bike for 15-20 minutes
** Cardio is sometimes substituted for an intense match of tennis.


I have noticed my muscles are starting to become defined on my arms and legs and my endurance has improved a ton, I am just concerned about the weight loss. (The amount)

I have a lot of energy and fall asleep really early. (10:30pm)

Any recommendations/ideas?

are you keepingtradk o calories in a program like FitDay - Free Weight Loss and Diet Journal or something similar?

Your fiber is awfully low, I'd dump the cheerios and switch to a higher fiber cereal...

do read the stickied threads around the forum, and you'll get a lot of info on improving your workout...

Thank you.

I am at 152lbs and just completed my first marathon!
