No lectures from this quarter at all - many of us, myself included, have needed to lose a lot fast. My pitfall was eating too little; after a great first week, I was eating only about 800 cal/day and my body thought I was starving, so it clung desperately to every morsel I ate and wouldn't shed more than a pound a week.
What worked the best for me was totally avoiding the BRPPs - bread, rice, potatoes and pasta. Complex carbs had to go. When I ate just lean protein (fish, chicken, turkey; no beef at all 'cuz of cholesterol concerns), vegetables, yogurt (for calcium) and low-glycemic fruits, I lost 4 pounds a week. I also greatly reduced my sodium intake. I guess my average daily intake was about 1200 calories total. But I didn't count calories - just measured portions. My husband did the same (about 1600 cal/day), and last year he lost 70 pounds and I lost 94.
We were also exercising 5 days/week, taking a daily multivitamin, drinking 8-10 glasses of water daily and didn't fast at all (to avoid that "body thinks we're starving" problem). We worked out this routine with a nutritionist and got lab tests (blood, cholesterol, etc.) every 3 months, so we knew we were healthy. And because we ate a variety of fruits/veggies/meats, we didn't go nuts from diet monotony. We ate like this for about 3 months, then gradually starting adding back small amounts of the BRPPs.
Of course, I realize you're not looking for a long-term plan like we were; I just wanted to let you know about the no-BRPP method. For us, shedding starchy carbs was definitely the key to kicking our metabolisms into high gear, so something similar might help you, too.
Remember also to vary your exercises and cardio work. Once your muscles get used to a routine, they don't work as hard. Realize, too, that a lot depends on what you weigh now - if you don't have a lot to lose, you just won't lose a lot. Good luck!
