(I realize we're at over half a thousand posts in this thread, and surely this has been covered before... but because this is a recent piece of discussion...)
No, dinners alone aren't over 2000 calories.
1. Shrimp fried rice (huge portions, maybe 4-5 cups?) 1,605 calories
2. 2 Whoppers & large fries 1,864 calories
3. 2 Neoguri ramen and eggs 1,274 calories
4. Denny's steak omelette with bread & potatoes ~1,200 calories
5. Yoshinoya 2 large beef bowls 1,920 calories
6. El Pollo Loco 2 shrimp bowls 1,420 calories
SO, no, I'm not pulling your legs, they're not over 2,000 calories.
Thanks for the clarification.
Okay. So....
If you're really ONLY eating these individual meals each day (as in, you ONLY eat #6 on Friday, as an example)...
... and you're running 8-10 miles each day...
You are
undereating by around a thousand calories. Or more.
(for now, let's set aside how terrible those food choices are, too)
What you're doing is starving yourself. Your #4 -- Denny's omelette at ~1200 calories -- is already a few hundred calories below the daily needs of a
sedentary individual. You ran and burned a thousand calories, so that's almost your entire meal spent on the workout, leaving only a couple hundred remaining to operate your heart, lungs, brain, and everything else in your body.
What BoneDaddy is getting at is 100% correct. You're telling your body to shut down and put all your food intake into reserves commonly known as "fat".
I lost 5 pounds a month, like clockwork, eating between 1800-2800 calories per day, with the higher amounts on workout days. I also didn't
solely run (in fact, I hardly ran at all), but I did a big variety of workouts, everything from weights to kickboxing to yoga to soccer. I didn't work out every single day, but instead had one or two off days each week.
And, I didn't work out on a full stomach, either. I still had breakfast (at around 0630), and I still had lunch -- but I'd work out either first thing in the morning or just before lunch.
I went from almost being forced to shop at Casual Male XL to picking my shirts at Express. I could see the "Jesus lines" in my upper hip/lower abdomen area. I still couldn't manage a six-pack because I've got plenty of loose skin and would need a
very focused nutrition regimen, but still, the first spring day when I went for a run in a compression shirt, I almost didn't recognize my own shadow -- my torso had become less of a potato and more of a "V" shape.
