In all seriousness though, it's not that hard. The motivation to keep it up is the hard part. Stop eating and drinking shit with a lot of sugar in it, eat smaller meals, walk everywhere, use the stairs instead of the elevator, etc. I'm going through this right now myself, and I've dropped 26 lbs in 4 weeks.
I was routinely killing 40+ ounces of Dr. Pepper A DAY. I'd buy a 2 liter and finish it before the day was over. I bloated up to 271 (at 6'2) and couldn't freaking stand it. First thing I did was find a replacement - just iced tea - for all the damned soda. I now have maybe one 32 oz. soda a week. Hope to completely get rid of sodas all together at some point, but in reality, it's not really THAT necessary. I walk to and from work 4 days a week, 3.1 miles each way, and when I say 'up hill both ways' I mean it lol. I live on one side of a massive hill, and I work on the other. It's basically 1.5 miles up hill, then 1.5 miles downhill in both directions. There's a Taco Bell next to my work, and I used to eat there all the time. I'd eat an entire Grande Combo (10 tacos/burritos) all to myself at least twice a week. Now, the most I've had is two bean burritos and a chicken soft taco. Normally it's just three chicken soft tacos and a water. I don't eat candy, so that wasn't anything I had to worry about. I also could eat an entire large/XL pizza in one sitting. Now I try to limit myself to 3 slices, 4 at the absolute most.
Yes, it was PAINFUL starting this. But I persevered, and it's starting to show. Friends I don't regularly see in real life are starting to notice I've gotten slimmer. Pants don't fit anymore. Belt is down 2 notches already. It's a great feeling, and seeing the results motivates me to keep going. I'm hoping to be down around 220 or LESS by X-mas, at which point I plan on starting to bulk up on muscle :-)
As far as Weight Watchers, et. al, I'd say stay the hell away from it. It's a massive waste of money. You don't need to pay anyone to lose weight. No-carb diets, no-fat diets, basically anything with DIET in it isn't going to work. It's all about balance, not extremes. Sure, if your family members learned portion control by using WW, fine. But if it took them spending hundreds of dollars to figure that out, that tells me there's more wrong with them than just watching what they eat >.> I think it's quite obvious. If you're killing an entire pizza, you might want to think about NOT killing an entire pizza. See? Portion control, and I don't have to buy individually frozen meals completely loaded with salt to do it.
