This makes sense: if there are less fat cells full of stored fat, and less of them to fill after weight loss, then it is intuitive that there will be fewer circulating triglycerides.
Some of us have wondered whether those fat cells, when emptied after weight loss by dieting, cry out to be filled. (or send out hormones or hormone-like signals) to increase calorie intake.
The research doesn’t definitively prove that liposuction caused levels to drop, however, and an outside researcher questioned the value of the study.
The study looked at 270 women and 52 men who underwent either liposuction, a tummy tuck (known as an abdominoplasty), or both. On average, the patients were slightly overweight, although they ranged from nearly underweight to morbidly obese.
The patients underwent fasting blood tests before surgery, one month afterward, and again three months afterward. At three months after surgery, triglyceride levels dropped from an average of 151.8 milligrams per deciliter (mg/dL) to 112.8 mg/dL in patients who underwent liposuction alone, representing a decrease of 25.7 percent; they fell by 43 percent in those with levels considered to be “at risk” — that is, 150 mg/dL or more.
Levels of white blood cells also dipped after liposuction and in patients who had both procedures. (High white blood cell counts are linked with an increased level of inflammation within the body and have been associated with coronary heart disease, high blood pressure and diabetes.) Levels of cholesterol and blood sugar didn’t change significantly.
Commenting on the study, University of Colorado researcher Rachael Van Pelt, who has studied the after-effects of liposuction, said the findings are “virtually meaningless” because triglyceride levels vary from day to day, and the researchers didn’t include a control group.
