change of calories

My sports nutrition coach is making some changes to my diet. On workout days I used to eat 390 grams of carbohydrates. On non-workout days I'd eat 190 carbohydrates. Now things are changing a bit. I'm going to be eating 250 carbs 6 days a week. Once a week, the day of my choosing,  I'm scheduled to eat 410 carbs.

Today I had a really hard workout. 2 hours and 20 minutes of %60-%90 of max. I needed the fuel to get through a workout that intensive. Before training i had two cups of white rice mixed with 1/2 cup of skim milk,  coffee with 2 TBSP half n half. During the workout i drank 2 servings of Gatorade and a half scoop of whey protein. Post workout i drank a shake with 1 cup skim milk,  1 scoop protein, 1 banana, 2 TBSP peanut butter, BCA's, & glutamine. The rest of the day I only had 70 grams of carbohydrates left to eat. I had enough protein and fat to keep me from getting hungry, but eating only 70 carbs the rest of the day made me grumpy. I'm not sure if it was my bodies blood sugar levels dropping or what, but i turned into an a-hole the rest of the day. As long as I don't lose my strength and speed gains I'll be really happy continuing to lose weight,  get thinner, become faster, & feel better about myself. Today I keep trying to remind myself that my nutrition coach is the bomb, plus he's a serious weightlifter too. So I know he understands what it takes to lose weight without losing performance. But I'm like an old grumpy man. I freak out about changes. I'm trying really hard not to freak out,  because like i said, my nutrition coach has a life time of eating healthy and competing seriously in athletics to base his reasoning on. I've even seen it first hand the last month. I've lost 14 pounds while recovering faster and making greater gains than I ever have before. Both my weightlifting coach and nutrition coach are ALWAYS having to remind me, "trust the program Cody". So right now I'm doing my best to simply focus on trusting the program and ignoring my fears.
