If you really set on losing weight then I would first suggest watching this:

YouTube - ‪How To Lose Weight - How to Start - Healthy Weight Loss - Losing Weight The Hard Way Antishay Q&A‬‏

This I feel is the most important part of losing weight, watch it and commit to the plan, don't give up, don't give in, don't think "I will do it tomorrow" or "its to late to do it now, its night time, I will just do it in the morning" because the fact is, it is night time (or not) but who says that work outs can't be done at night, if I am honest every time I have worked out this past week, it has been done after everyone in my house has gone to bed, so when I am doing my squat jumps in the living room I don't have to worry about people coming in while I'm topless and sweaty, cause if I am honest, I am no slim jim, but once I have gotten down to a decent weight maybe I will do it during the day or who knows, I may do it at night AND day.

After you have watched this the proceed to watch this:

YouTube - ‪How To Lose Weight Fast Home Workout - Quick Belly Fat Burning Exercises - Under 15 Minutes‬‏

I have committed to lose weight for my sisters wedding, for my personal health and to stop the endless jokes about my weight, I have been only doing it for about a week and if I am honest, this is the first time I have ever spoken to anyone about this, I just decided to do it off of my own back, I do the workout in the second video every day and so far even though its only been a week I find myself feeling really positive in my decision and (most importantly) I am working towards the goal of feeling good about myself again.
