TL;DR
No effects of frequent dieting or exercise on basal and stimulated lipolytic activity were observed and significant differences in weight loss and fat loss were revealed between D and DE groups but not between yo-yo and non-yo-yo dieters.
Abstract
Body composition, maximal aerobic power (VO2 max), resting metabolic rate (RMR), and lipolytic activity of abdominal adipocytes were measured in 20 women (body mass index [BMI] = 33.5) during 14 wk of exercise training (4 h/wk at 60% of VO2 max) and dietary restriction (840 kcal/d). Frequent dieters (yo-yo) and women without a dietary history (non-yo-yo) were matched into the following groups: diet-exercise yo-yo (DE-Y), diet-exercise non-yo-yo (DE-NY), and diet-non-yo-yo group (D-NY). After 14 wk significant differences in weight loss and fat loss were revealed between D and DE groups but not between yo-yo and non-yo-yo dieters. RMR decreased in all groups but there was a significantly smaller decline after 14 wk for the diet-exercise groups. No effects of frequent dieting or exercise on basal and stimulated lipolytic activity were observed.

The LancetEFFECT OF CALORIC RESTRICTION ON ENERGY EXPENDITURE IN OBESE PATIENTS
209 Citations1969GeorgeA Bray
The energy expenditure of fourteen grossly obese patients was investigated during periods of high and low caloric intake and a fall in the activity of the two enzymes in the glycerophosphate cycle seems to support the concept that the body can adapt to caloric restriction by decreasing its energy needs and by becoming metabolically more efficient.
MetabolismMetabolism of mammary, abdominal, and femoral adipocytes in women before and after menopause

Menopause in women seemed to be associated with a diminution of not only the increased lipoprotein lipase activity of femoral adipocytes, but also of the high lipolytic response in abdominal and mammary adipose tissue, and it is suggested that female sex steroid hormones exert regionally specific effects.

For both groups, aerobic exercise did not have a prolonged stimulatory effect on metabolic rate after the exercise had finished and Mild exercise was more effective than aerobic exercise in increasing daily metabolic rate.

Adult male Sprague-Dawley rats were fasted for 65 h and then refed ad libitum for 8 days, during which time body weight and body composition returned to the levels of nonfasting controls, suggesting that starvation-induced energy conservation processes seem to persist during refeeding.
