What is the best way to keep track of your calorie intake? I have no idea how many calories are in a tuna sandwhich.
 
And how many calories should I be eating a day? Or actually how many should I NOT be eating?

Weigh yourself regularly. If you are careful not to do any exercise, you'll be able to compute the calories you consumed from the weight gain.

Well it is pretty complicated. Put the food in a metal cup submerged in water and measure temperature in °C. This is T initial. You have to burn the sandwich in a metal cup to get T final. Measure the mass of the water in grams, multiplied by 4.18 Joules/g°C, multiplied by delta T. To summarize:

q=Masswater x specific heatwater x ΔTwater

(q=Heat in calories or joules) (T=temperature) (ΔTwater=Tfinal-Tinitial) (spefic heat of water= 4.18 J/g °C)

(Masswater = Mass of water in box - mass of box w/o water)
(joules to calore conversion 1 calorie=4.184 Joules)

So make sure you burn the whole sandwich first, then you'll know everything. :O

By tuna sandwich he means his wife laying in the middle of himself and BeerBoy.
 
Seriously, though, check out MyFitnessPal.com. It'll set you up with a great way to track all the food you eat, how many calories are in that food, how many calories you need to cut to lose weight, etc.
 
Thanks! I feel you on falling off the wagon. I ate 1 and a half medium Dominos pizzas on Saturday night. It was pathetic. Seemed like I crapped about 40 times the next day. Each trip to the can just drove home the shame.

If you have problems falling off the wagon, maybe try doing the Seinfeld Calendar. Basically put up a year calendar on a wall and put an X on every day you exercise or eat below a certain number of calories. The goal becomes not breaking the chain of X days for as long as you can. Jerry Seinfeld developed it for writing, but it works well with weight loss, from what I hear.

I'm just starting it now because I've found myself getting a little lax lately and I think a good visual reminder might help.

Honestly, I think the real key to long-term weight loss is to just switch up systems every so often. And remember that it's 80% diet, 20% exercise.

Thats actually great advice! Thanks for that and repped! Oh and also yes myfitness pal is AWESOME I have that on my Iphone and it breaks everything down for you. And tells you how many calories you have left etc. Keep up the good work Mook!
