Even if the mother is malnourished, Dr. Simeons noticed that the mother would still give birth to a healthy baby. That is how he discovered and developed this diet. After delivery, the mother continues to have some hCG in her body. The levels drop off quickly, but I think some hCG hangs around longer than some people realize.
After my very first round when I lost 45 pounds in 2007, I went to eating according to Atkin’s because I still had another 50 pounds to lose and I was surprised that I couldn’t lose like I had in the past for a period of weeks. I think I still had enough hCG in my body that it interfered.
One other thing to note. One of my daughters had a miscarriage. She had to have weekly blood tests to make sure her levels of hCG were going down or else she needed a D&C to make sure nothing like a part of the placenta was left inside. It’s just one more way I think hCG hangs around longer than people realize.
Doing maintenance is a very crucial part of the diet. It’s a stage that resets the body to the new weight and it’s so important. Some do the diet right to the date of some special event and I totally understand. I have done that. Sometimes you can make up for it with doing a “steak day” or two. But it’s really very important to do at least 3 weeks of “maintenance” as described in Pounds and Inches and then stabilization. If you don’t, you can gain weight.
