P90X and diet for 155lbs/5'7"/28yo

Hi I'm just wondering if anyone can tell me if I am consuming enough calories for the P90X program. I'm a 28 year old male, 5 foot 7 and 155 pounds and MFP is telling me to consume 1760/day if I want to lose 1.5 pounds a week. Im trying to get down to 135-140 pounds and be cut with rounder shoulders. I get between 7 to 8.5 hours of sleep a night and eat pretty healthy (I think). An example of a day usually consists of something like this.

Breakfast: -vector protein bar
-greek yogurt (1container) with chia/buckwheat (1tbsp)

Lunch: salad (tomato, cucumber, avocado, black beans or lentils with zesty light dressing)
-can of sardines or 3 eggs or can of tuna

Snack: can of tuna or oatmeal with almond milk (unsweetened)

Dinner: chicken soup (chayotte, carrots, peas, chicken thigh, onion) sometimes with side salad

Snack: carrots with salad dressing

Sometimes I don't even hit 1500-1600 Cal mark is this too low if I'm doing 90 mins of workout 6 days a week? What's missing in my diet?

Thanks for your help!
