hCG diet leaves some hungry for less
The controversial, ultra-low calorie hCG diet is back in vogue, thanks in part to easy online access to the pregnancy hormone it depends on

The 53-year-old Catonsville nurse went on the hCG diet, named for human chorionic gonadotropin, a hormone that is produced naturally in pregnant women and often used in fertility treatments to trigger ovulation.
Promoters of the diet say hCG suppresses the appetite, making it easy to stick to a diet of just 500 calories a day. They also say it helps the body burn fat while retaining muscle. Patterson said the plan helped her lose 58 pounds in just four months.
"I'm probably the smallest I ever remember being," said Patterson, who dropped from a size 20 to a 12. "You want to go shopping again for clothes. That part's just really great. You just have to keep thinking about that when you want that big old dessert."
While Patterson is entirely sold on the benefits of hCG, many medical experts doubt that the hormone is helpful. And they worry that 500 calories a day amounts to a starvation diet, which can cause heart damage and other health problems. The potential health risks could be higher in Maryland and other states, where telemedicine laws allow doctors to prescribe the drug, derived from the urine of pregnant women, with just a telephone consultation, experts warn.
The diet was developed in the mid-1950s by Dr. A.T.W. Simeons, a British physician. It has come in and out of vogue since then, with its current comeback fueled by the availability of hCG online.
While the number of people on the hCG diet is not known, the American Society of Bariatric Physicians reported a surge in its popularity last year, when the society also took a formal position against it on the grounds that it was not effective and did not provide sufficient protein.
"I think it is something that is not well-founded in science," said Dr. Larry Cheskin, medical director and founder of the Johns Hopkins Weight Management Center at the Bloomberg School of Public Health. "Anyone who goes on a 500-calorie diet will, of course, lose a lot of weight quickly, although probably not safely."
Even with a patient under medical supervision, Cheskin said, he would rarely recommend a diet of less than 800 calories a day. About 1,200 calories would be more typical, he said.
Cheskin also doubts that the hormone, which some dieters inject themselves with and others take orally, has any effect on appetite.
"Is the injection working, or is it a placebo effect?" he said. "I've seen people who have tried it, [but] maybe this is a biased sample. If they're coming to me, it didn't work."
Patterson decided to give the diet a try after a friend had success with it. She had put on about 40 pounds over a four- to five-year period when she was busy working and caring for her ailing mother, who died about a year ago.
"I was caring for Mom. I would eat fast food a lot and didn't care," said Patterson, the mother of three grown daughters.
In early January, she started taking the hormone orally twice a day, adhering to a 500-calorie diet.
"The first week or so I was [hungry]," she said. "It was hard to adjust." But eventually, she said, she wasn't battling hunger so much as ennui.
"It's a very boring diet," she said.
In the morning, she had only water and coffee. Lunch and dinner were always the same: 31/2 ounces of lean protein (steak, chicken or white fish), one cup of a vegetable, a single piece of Melba toast and a serving of fruit, which could be a whole apple or orange, a cup of strawberries or half of a grapefruit.
Dull as it was, she said, the diet allowed her to drop pounds. Patterson used to consume "probably 3,000 calories a day, maybe 3,500," mostly in the form of fast food. She doubts she could have slashed that to 500 calories without the hormone.
"I've probably been on every diet known to mankind, and this one just works for me," she said.
