Is it possible to loss 5 pounds in a week without going on a, "extreme oh my god , I'm about to pass out diet".? If so, does anyone know how to do it?

It is not uncommon for severely over weight people to lose 5 pounds or more a week for a while before the weight loss slows down. But if you don't fall in that section..there is no healthy way to lose 5 pounds of fat a week...

Dependent on several factors, yes this is possible.

For example: If one's body is accustomed to a rather HIGH calorie intake and no exercising (weight training regularly, cardio, etc), and then suddenly drops the calories to a reasonable deficit AND includes a 3X or more training per week, the body can react rather strongly to this new environment.

However it is possible to lose 4 pounds of fat and gain 1lb of muscle in this example, but the scale will show a loss of 4 pounds. Most new persons miss this important element when they first start out and get frustrated when the scale is moving down slowly when they are getting a DUAL benefit.

Also, I think drastic changes in diet can cause your body to unload excess waste (gross yes, but I've heard you can hold some extra poundage in your intestines), and also your body will release a lot of water weight once you start drinking the appropriate amount of water.

But, I think impossible to lose 5 pounds of pure fat in one week.

Just take more time, do it right, eat right, lift, do runs/biking/HIIT, and you will be much happier with the results.

Imagine a guy who weighs 160 pounds and has 8% body fat. Total fat = 12.8 lbs. He's in pretty good shape. If he aims to drop 5 lbs of all fat in 1 week, then he'll be at 155 lbs, fat weight of 7.8, and his body fat % would drop to 5%.

The question that I'd ask, though, is what type of calorie deficit would he need to lose those 5 lbs in that week? He'd need a deficit of roughly 3500 calories per lb, or in other words, 5 x 3500 = 17,500.

What is his maintenance level? If he's very active (but not competing in the Tour de France), it's probably in the ballpark of 3000 to 4000 calories total. Even assuming it is the high end of that range, that means that his total weekly calorie needs are 4000 x 7 = 28,000.

Our hypothetical guy would have to cut his calories down to 10,500 for the week, which averages out to 1500 calories per day. And his body would have to be able to continue working at its current activity level to keep the deficit that high and also be tailored to maintain all his muscle too (to make sure that only fat is lost).

Is this doable in one week? Of course. Would I recommend it? Of course not. Would I even want to go anywhere near someone attempting this? Hell no. He'll be hungry, irritable, frustrated at watching his performance drop, and tired as anything.

You can play with the math to see how other people would be affected, but note that the key comes from that very large deficit you have to create. Someone who manages to consume far more than they need could swing the 5 lb of fat/week plan. Anyone else, no matter how much they weigh, probably can't.

And when you see obese people lose a lot of weight in one week, they are not necessarily dropping pure fat. There is a lot of water fluctuation going on.
