How weight loss can affect your body

Losing weight may lead to changes in your body because everyone's body responds differently. Consider the information below as part of your weight-loss journey.

Understanding bone density and weight loss

As we age, we naturally lose bone density, but weight loss can speed up the process and bones can become frail.

Bone loss can affect men and women differently

In premenopausal women, across weight-loss studies, significant weight loss has been associated with bone density loss up of to 1.8%.

In postmenopausal women, across weight-loss studies, significant weight loss may lead to a 1%-4% loss of bone density.

Although these percentages seem small, this can lead to a higher risk of fractures and an increased chance of osteoporosis.

Men also experience bone loss. Starting in their 30s, they may begin to experience declines in bone mass that add up over time, which can increase the risk of osteoporosis later in life.

This is why it's important to think about your bone health on your weight-management journey. When talking to your health care provider, make sure you're asking about how to support your bones while losing weight.

Fatigue

You may feel tired during weight loss, especially if you’re not eating enough nutrients and calories or drinking enough fluids.

Hair loss

Some people may notice increased hair loss during significant or rapid weight loss. This is often temporary and related to not getting enough protein and nutrients in the diet.

Gallstone formation

Gallstones are hard, pebble-like pieces that form in the gallbladder. There are 2 main types: cholesterol stones (made mostly of hardened cholesterol) and pigment stones (made from extra bilirubin, a substance made when red blood cells break down). During rapid weight loss, bile (the digestive juice your liver makes to help break down fat) can change, and the gallbladder may empty more slowly. This can lead to gallstones.

Even though healthy eating and physical activity can support your health during weight loss, bone density needs a different strategy.
