The government is cracking down on another diet-pill. The FDA, has told the manufacturer of what is called "Herbal Fen Phen" to either change the name, or face government seizure of the product. Ed Yeates joins us now. What is the concern, Ed?

It's probably obvious. There are a lot of products out there which come very close to the name but have nothing to do with the original prescription fen phen.

The FDA claims there is no evidence this product which is actually called herbal fen phen even works. And though it is a natural product, it too can bring on high blood pressure and heart problems. The manufacturer says it's done nothing illegal, but the government says abide with the name change or face the consequences. Today's action does not help Utah dieters who are still searching, still trying to cope with what we call "Life After Fen Phen."

In fact for Kathy Schneider, life after fen phen - is STILL fen phen. She had a couple of months worth of Pondimin in inventory before the product was pulled, and since then her friends have given her even more...

((KATHY SCHNEIDER: "THEN I HAD PEOPLE WHO DECIDED THEY WERE NOT GOING TO TAKE IT ANYMORE, A LITTLE NERVOUS ABOUT IT AND THEY VOLUNTEERED TO GIVE IT TO ME."))

She once weighed 305 pounds. Bad knees made it almost impossible to exercise. In fact, she could hardly walk from her car to the office. But then fen phen came along.

(("I LOST 138 POUNDS IN A YEAR."))

The weight peeled off at the rate of two pounds per week - and for the first time it stayed off.

(("I GO FROM EARLY MORNING UNTIL LATE AT NIGHT AND I DO THINGS I NEVER EVEN DREAMED OF DOING OR FEELING AS GOOD AFTER I HAD DONE THEM."))

Kathy is taking reduced dosages of Pondimin, and has regained about 10 pounds. The left over supply will eventually run out, and that makes her angry. She has a genetic problem with obesity and says she needs that partnerhip with medication to keep the weight off. Kathy joins a host of other consumers desperately searching for a replacement that is as good as the fen phen cocktail.

Pharmaceutial companies actually have two new drugs holding in the wings. In fact they would have hit the market by now had it not been for the fen phen withdrawal.

((DAVID JACK M.D., S.L. PHYSICIAN: "BOTH OF THOSE AGENTS WERE ANTICIPATED EARLIER THIS YEAR AND BOTH HAVE BEEN DELAYED AGAIN TO THE BEST OF OUR KNOWLEDGE UNTIL EARLY NEXT YEAR."))

One is a genetically engineered fat blocker called Orlistat, which prevents absorption of over one third of the fat you eat.

((GEORGE VAN KOMEN M.D., SALT LAKE PHYSICIAN: "IT'S BEEN STUDIED FOR OVER TEN YEARS. IT'S VERY SUCCESSFUL, VERY FEW SIDE EFFECTS."))

(("THESE PEOPLE SEEM TO LOSE ON THE AVERAGE - ABOUT TEN PERCENT OF THEIR WEIGHT."))

The second one waiting backstage is called Meridia. This is a classic fen phen replacement since it raises both chemicals the cocktail regulated before, but via a different mechanism and with fewer side effects.

Even though these products will have FDA approval, consumers may be a bit gun shy to use them.

Tomorrow night, a look at some other herb and food supplement products claiming to pull the weight off - and those folks who've simply returned to the old fashioned way of losing weight.
