(obviously, my comment is a humorous approach)

I started on Jan 14, 2013 and I've lost 23.4 pounds as of this week. That's 2 lbs a week over the last 12. It's hard, but it can be done. You need to be disciplined, eat CLEAN (no processed junk, more fruits and veggies, limit alcohol and sugary soda, etc), and most importantly, track everything you put in your mouth. I have a friend who said she stops tracking after she's hit her calorie limit. That's won't help you because when you don't track completely, every day, you're not living in reality (not you, but whoever doesn't track consistently). I also got a reality check on what a true portion is. When I first started, I measured everything because often, what we "think" is a cup, or we "think" is 10 chips, or we "think" is 3 ounces, is really more. I also walk 3x a week, moderate pace, on our treadmill. I had a few weeks where I gained half a pound, often happens during that time of the month, but if you gain a bit, don't beat yourself up. Just keep sticking with the plan and the weight will slowly melt off, which is the safe way to do it. I too have read and am following the Eat to Live book by Dr. Joel Furhman like the poster before me (Jan). Good luck!

Work your *kitten* off when you workout. don't stop when you get tired, go the extra mile. It'll work.

I started on Jan 21, 2013 and have lost 28 lbs so far...If I can do it, anyone can...seriously. You just have to be dedicated and motivated...work out on days when you don't want too. Pass up on the monthly birthday cake at work and the candy bar calling your name in the vending machine.

If you want it bad enough, you will do it.

Good Luck

I like Dr. Oz. Maybe that is just me lol.

I see people do it and if I lose 2 pounds a week that's 24 pounds in three months but hooow? Just eating in my macros and working out? Will that really work? How do I stick to it?

Anyway, you haven't responded yet but I will try to answer some of your questions.

It depends on how much you weigh. If you only have 20 lbs to lose, say you are 140 and want to get to 120, it may be harder than you think. At your age though, it may be easier. It all depends on your dedication (in your control) and your body chemistry (out of your control).

Your best bet would be to eat A LOT of veggies (leafy greens especially) and some fruit, try to limit your animal products too. Don't eat meat at every meal and limit your dairy to a few times a week or switch to something like almond milk. Eat some nuts as snacks, take a multivitamin, drink a lot of water, no soda or diet soda, eat beans to replace some of that protein you won't be getting from all the meat (kidney beans, black beans, lima beans... etc. if you get them canned make sure to rinse and drain them), and some whole grains here and there such as brown rice, quinoa, etc.

Exercise at least 2-3 times a week with cardio and mix up some weight training in there. Remember muscles help burn fat!

Sticking to it isn't the easy part, it is the hardest IMO. If you are dedicated and ready, you can do it. I suggest reading "Eat to Live" by Dr. Joel Fuhrman. Watch documentaries such as "Fat, Sick, and Nearly Dead" and "Forks over Knives".

Adjust your taste buds to get away from the processed sugar and crap. Choose exercises that you like and switch them up (as your body will get used to them and you will get bored).

Most of all remember this quote... "Whether you think you can or think you can't, you're right".

it will also depend on where that 20 lbs are... I was certain when I started losing that I would lose 20 lbs quickly... I'm down 23 lbs now in something like 7 weeks... if I didn't have 50 to go at the beginning, that would actually be considered a concern! If it's your last 20 lbs, or you aren't overweight, then it's a little harder to get lbs off... especially if you sculpt your body in the process.
I had to join weight watchers and quit the gym for my last 10 lbs last time (bad move, ultimately my skinny closet's demise) because a clean diet and exercise just weren't cutting it

Why was WW and quitting the gym bad, did you gain?
