Need suggestions for healthiest way to lose weight quickly!

So you really only need to lose 6 lbs? Eat less. Move more.

Advocare 24 day challenge! I've lost 9 pounds in 11 days! But it's 200 dollars so it really doesn't help lol.

I'll spare you the theatrical self-righteous posting, because I'm not perfect either. And sometimes a good loss in the beginning is a way to get motivated, and stay motivated, especially if you are providing your body with the proper nutrients.

At your height and weight (I'm the same height), it's especially difficult when it's a small loss. My doctor (yes, my real physician) recommended the 17 Day Diet as a kick start to weight loss, and told me it wasn't bad, especially if I ate the vegetables. Lean protein (a LOT of it in the first 17 days, which is all you need), vegetables anytime. Think tuna fish on a bed of spinach and tomatoes, that kind of stuff you can eat until you can't hold anymore. But it has to be lean protein, no red meat, no sausage, no lunch meats--just real chicken, turkey and fish. Almost any veggies you can think of except corn, and squash and then you can have fruit until 2pm in the afternoon. Apples, pears, berries of any kind, citrus - no bananas or pineapple as they are higher glycemic and up your blood sugar. Two yogurts or probiotics a day, low fat hard cheese like parmesan, and green tea. Of course 8 glasses of water a day and no alcohol (which really sucked for me!). Also no, sugars, which also sucked. But it was only for 17 days, and once I lost and went on to the other phases that included more carbs, sugars, and alcohol, I didn't gain back.

Amlased. Its like drinking a protien shake 3 times a day for 3 days with vegetable broth in between then 2 shakes one meal then 1 shake two meals.
Its a healthier version of a protein shake or slim fast and I found that it makes me feel great.
I will be using a supplement forever :-)

find a very light weight dress and light shoes to wear on weigh-in day

This was going to be my suggestion.

If you find that eating healthy doesn't get you where you want, I honestly would probably do a fast/apple fast or some such thing. I did a 3 day apple fast and lost like 8 pounds one time. It all comes back sure but I don't think it would hurt you long run and it might get you to your money goal.

I would have planned ahead of time and not left it to the last moment. Crash diets are not good for you.

Can you provide any evidence that a short term "crash diet" such as the OP proposes (10 lbs in 30 days) is "not goof for you" when "you" is a person wtih a BMI above the healthy range?

Excuse me..are we butthurt? Oh and 10 lbs in 30 days is not BAD..I'm saying the "Crash dieting" is not good for you.

I'm saying with KNOWING ahead of time (OP said this goes on every year). ..that a good "healthy" lifestyle change could have accomplished the 10 lbs without having to put stress on your body by "crash dieting". I have tried many a diets and I would rather go the long road of changing my eating habits then downing shakes or taking diet pills. I myself think any crash diet is bad for you..you may get results but you are going to gain back the weight and maybe more. But that is my opinion.

My butt is fine, thanks for asking. What evidence do you have that losing 10 lbs in 30 days would put stress on the OP's body? Your personal preferences aside.
