That 1,200 calorie day is sorta dangerous if I am not mistaken.
Even for me with my metabolism I stand at 5'11" and weigh in around 160-164...not to sure on the weight as I haven't weighed for a few weeks now.
But for me 1,200 calories is a good sized meal for me.
If I take in 1,200 in a single meal it'll last me about 2-3.5 hours before I start feeling hungry.
I know that I burn at least 300-calories standing still due to how I've built my metabolism. If you figure I could burn 200/hour on average throughout the day that's nearly 5 thousand calories.
With the training you are talking about you should be taking at least 2,500 to 3,000.
If you don't have more than 2 thousand you are going to start having issues with starving the body.
Throughout life there are bumps along the way some may be painful...others not...who gives a damn in the end you'll still die
