Weight loss for women

How women's bodies, hormones and life stages affect weight, and how to lose weight sensibly, including after pregnancy and around menopause.

The basics of weight loss are the same for women and men: eat a little less energy than you use, and keep it up over time. But women's bodies differ in ways that affect both how weight is gained and how realistic goals should be set, and several life stages bring changes of their own.

Set realistic goals

Women naturally carry a higher percentage of body fat than men. That is healthy and normal, and it is needed for hormones and reproduction. Very low body fat, whether from extreme dieting or intense training, can stop menstrual periods and weaken bones. So the goal is a healthy weight, not the lowest possible number.

Women also tend to need fewer calories than men, because they are usually smaller and have less muscle. That means the same meal or snack makes up a bigger share of the day's needs. You can estimate your own resting needs with our basal metabolic rate calculator, and aim to lose about 1 to 2 pounds a week, the pace the US Centers for Disease Control and Prevention (CDC) suggests.

Your cycle and cravings

Many women notice more hunger and cravings, especially for sweet or rich foods, in the days before a period, and weight can rise by a pound or two from water retention. This is temporary. Regular meals with protein and fiber, from foods such as beans, oats, whole grains, vegetables and fruit, can help keep hunger steadier. There is more about this in our article on food cravings.

After pregnancy

Some of the weight gained in pregnancy is lost at birth, and more in the weeks that follow as the body sheds extra fluid. The rest usually comes off gradually over months, and that is fine. Celebrity "bounce-back" stories set unrealistic expectations.

If you are breastfeeding, your body needs extra energy: the CDC suggests about 330 to 400 more calories a day than before pregnancy for well-nourished mothers. This is not the time for strict dieting. Focus on nourishing meals, drink to thirst, and add gentle activity, such as walking, when your doctor or midwife says it is safe. Weight usually comes down gradually with time and activity.

Around menopause

Many women find it easier to gain weight, and harder to lose it, in their late forties and fifties. Falling estrogen levels shift where fat is stored, toward the abdomen, and loss of muscle with age lowers the calories burned. Fat around the waist is linked with a higher risk of heart disease and type 2 diabetes; the US National Heart, Lung, and Blood Institute considers a waist of more than 35 inches a sign of higher risk for women.

What helps at this stage:

  • Strength training at least twice a week, to protect muscle and bones, along with regular aerobic activity.
  • Protein at every meal, which helps you feel full and preserve muscle.
  • Plenty of vegetables, fruit, whole grains and beans, and fewer refined snacks and sugary drinks.
  • Watching alcohol, which adds calories and can disturb sleep.
  • Enough calcium and vitamin D for bone health, from food first.
  • Sleep. Hot flashes and night sweats can disturb it, and poor sleep makes cravings worse. If symptoms are troubling, talk to your doctor about treatment.

Medical factors

Some conditions that are more common in women, such as an underactive thyroid and polycystic ovary syndrome (PCOS), can make weight harder to manage, and so can some medications. If you are struggling to lose weight despite real changes, or your weight changes without explanation, see your doctor.
