10,000 steps a day not enough! “Researcher Anders Raustorp from the University of Kalmar added that the key to successful weight control was to set goals, keep a journal, and increase activity by 27% over a four-month period. The group recommends: Women aged 18-40 should do 12,000 steps per day and women 40-60 should aim for 11,000 steps per day. Women over 60 should do 8,000 per day. Men 18-50 years should do 12 000 steps per day, and men over 50 should aim for 11,000 steps per day”
Exercise Reduces Hunger for Some Women “In animals, leptin curbs appetite when body fat increases. When the levels of leptin rise, the hormone seems to shut off appetite and motivate physical activity. However, as obese people become fatter and their leptin levels rise, they become resistant to how the hormone works. … “Obesity interferes with leptin’s detection of exercise energy expenditure and with appetite suppression,” lead author Katarina Borer, Ph.D., University of Michigan, was quoted as saying. “Obese women perhaps need to consciously watch their calories because some of the hormonal satiety [fullness] signals don’t seem to work as well.” “
Hour's exercise 'to lose weight' “Women who want to lose weight - and keep it off - need to be exercising for almost an hour, five days a week, according to US experts. The University of Pittsburgh study found the 55-minute regime was the minimum needed to maintain a 10% drop in weight. Only a quarter of the 200 women in the study managed to lose this amount. A UK expert said it was clear that regular moderate exercise was the way to lose weight, and keep it off. … They were all told to eat between 1,200 and 1,500 calories a day, and split into four different exercise programmes, varying the intensity and amount of exercise carried out. After six months, women in all four groups had lost up to 10% of their body weight - but most could not keep this going. The women who did maintain the 10% loss were those who reported doing more exercise, on average 275 minutes per week. “
Intense exercise best for whittling down fat “While any type of exercise can do a body good, people who want to reshape their figures may need to boost the intensity of their workouts, a small study suggests. The study, which followed 27 middle-aged obese women, found that those who exercised at a high intensity for four months successfully shed fat from their midsections. Women who exercised at a low intensity, however, showed no such changes in body fat.”

Effect of diet and exercise on body composition, energy intake and leptin levels in overweight women and men. (J Am Coll Nutr. 2008) “CONCLUSION: A combination of diet and exercise resulted in a significant decrease in body weight in women and men; but this decrease was not maintained at one year follow-up. Serum leptin concentrations showed significant within-group decreases, but were not different among groups. A supervised diet and exercise program is effective for weight loss; however, once intensive participant-investigator and participant-participant contact is discontinued, weight regain ensures.”
