I've been involved in Martial Arts since I was 5.  I'm now 19 and have a Black belt in Kenpo.  I have lifted on and off throughout my teen years but 2 weeks ago, I decided that I have enough mass and want get a very lean and toned body.   I lift for two days and take every third day off.  But I still jog 3-4 miles daily and attend 2 1-hour Karate classes per week.   I am 6'3" and weigh 172 lbs.   My question revolves around my diet.  Is it possible that I am not eating enough even though I am cutting?  I am definitely noticing some change in my physique but I often feel tired and dizzy after my workouts.   I am a full time college student who also holds down 2 jobs so I need to be able to stay on my feet and get my studying done and perform well in the workplace.   Up at school, I am only able to eat twice during the day because of the kitchen schedule.  I normally eat the same thing every meal.  I eat at 12:30 PM and around 5 PM   My meals usually include about 1 cup of steamed greens (spinach, broccolli, green beans), 1/2 cup of rice, 2 egg whites, 8 oz. of tuna, 6 tomato slices, 1/4 cup of raw shredded carrots and sometimes 1/4 cup of chickpeas.  I usually drink a glass of water and maybe a small glass of cranberry juice.  I have been following this die religiously for the past 2 weeks.   Is my fatigue due to my diet or is there something else missing?   BTW I do not take any supplements or steroids.
