I've been passively giving myself a little extra caloric burn. I'm talking about maybe 30 jumping jacks, or intervals of 5 push-ups and 30 jumping jacks in 5 and 4 sets, three mornings per week; two pull-ups now and then (maybe 2-5 times per day); perhaps one or two sets of 3 lifts of a 35 pound kettle bell and 10 reps of curling a 10 pounder; and a few intervals of walking--walking, damn you--around outside for 15 minutes, a total 4-5 miles.

It's not a lot of activity. It's not all at once; the most intense training session is five minutes of doing like 25 push-ups in total.

My Fitbit reports 2700-3000kcal burn total, including my base metabolism.

Now my food sources sometimes go as low as sushi and edamame--350kcal-- for lunch, but frequently include chocolate almond milk (two cups, with four tablespoons ovaltine) and a breakfast sandwich (250kcal english muffin with egg, gouda cheese, and mushrooms on it--a good 300kcal itself), something like a BK whopper for dinner, and a two-piece chicken meal from Popeye's--which is friggin' 1000kcal in one meal. I get a surprising number of calories from tea (two teaspoons of honey or some sugar cubes makes like 120-180kcal in one glass) or chocolate milk, similar to what someone gets from soda--in fact, often I can get a 40oz soda from a fast food joint without inflating my calorie intake.

Despite that, I come in between 500 and 1800kcal under every day. That means some days I eat 600kcal for breakfast, over 1000kcal at lunch, and some 800kcal or so at dinner, and still come in 1000kcal under. I've had 1500kcal intake days--sushi and black beans are surprisingly filling for little intake--but if I've moved around a bit more than usual, I'm usually more inclined to eat an enormous hoagie with a ton of mayonnaise and cheese on it.

I lost five pounds in 4 days with my digestive system slowed to its original state (18-27 days of travel).

More importantly, I just feel...worn out. Sometimes my body aches, sometimes my muscles ache a bit; I'm not sore and broken--when I used to half kill myself bicycling to work every day while immensely out of shape, to the point that my heart would stop for a few beats, I'd feel outright wrecked--just a little... nauseated?

If I'm eating 2200kcal and coming in 1000 under anyway, should I be shoving another burger down my throat? Something just feels like maybe I'm not getting enough food. I was eating 2000kcal breakfasts fried in lard and butter when I was biking everywhere every day. Losing more than a pound a day average just seems wrong, even if my diet is fried chicken, fast food burgers, and half a dozen boiled eggs at once.
