Eat before? Or after?

I've heard that you should eat after exercising, even if you're hungry before/during your workout. That way your body isn't having to combat any extra calories you just added. But I've also heard that you should eat before you exercise so that you have fuel.

Any idea on which is right?

I'm not an expert but I think you can do which ever works best for you.  The book I am currently reading advocates a protein shake after each workout, but gives the option of a preworkout shake if you prefer.

Lot of trial and error and listening to other folks until I found what works for me.

When I'm doing weights, I eat breakfast after but I make a 1 1/2 serving of protein (I mix with water) and sip that a little during with water as well.  I usually do about half when I'm working out and half after.

If I'm doing my HIIT I just drink water during and have a 1/2 serving of protein after.

My plan is changing again, decided I'm not doing enough and I'm adding tabata back in.  I will regret that tomorrow!  So I've eaten my 2 hard boiled eggs and I'll work out in around another hour (I like those 2-3 hours prior)....water during...something carb for dinner, like pasta with steamed veggies and a little chicken.  Otherwise I'm useless the next day and recovery is really hard.  It's how I learned tabata and the few times I deviated I really paid for it.

okay, still a little new to this...what exactly is HIIT and tabata?

oopsies!  SORRY!  I'm so bad at not translating acronyms sometimes.

HIIT is High Intensity Interval Training.  I've heard it called sprint intervals as well and basically for that you alternate jog and run.  Jog should be at around 60% effort at a minimum...and run is 90+% effort. (for me sprint is 110% so literally everything I have so I push really hard)  You do 30 second intervals... So jog, run, jog, run, jog, run....etc.

For someone starting out you do 4 minutes on session 1 and 2 (1 day rest between sessions) and then on session 3, you add 1 min so 1 jog extra, 1 run.  So sessions 4 & 5 you do 5 minutes, then on session 6 you add 1 min. etc.  That's it.

*side note* when I started I did 2 weeks of power walk/jog to ease back in.

Tabata...is rough.  You do intervals of exercise at 20 seconds on (full effort) 10 seconds off, repeat.  8 sets total so each exercise block is 4 minutes.  I know some folks that do the same exercise, and others switch it up.  There's actually 2 great vid's over on youtube...can get the other one in the "video answer" area.

I don't do the chin ups and pull ups (no bar) so I added in burpees, and I usually do curtsy lunges as well (good example videos on youtube of those too in the kim kardashian (which I probably butchered spelling) butt workout) and then for the other 3 intervals (that had a pull up or chin up) I just double another exercise like hamstring curls or whatever I feel like that day.  So I more or less go similar to what Arnel is doing on his videos I linked above.  I push a little harder since I'm not wasted after 1 round, so I do 2...for 8 mins total. 

Tomorrow I'll be hurting places I forgot had muscles.  But it's a good hurt and will knock off this excess body fat.  Actually measured today and calculated and yikes.  Worse then I thought.
