Intermittent fasting (IF) works by alternating fasting and eating periods which prompt the body’s metabolism. Due to the growing success, research on IF and supportive apps are constantly evolving. Convenient IF apps like Fastic enhance the user's experience by tracking their progress and helping them stick to their fasting schedule.

With its growing presence and numerous benefits, why not give it a try? Well, while intermittent fasting has already proven effective for many, does it offer the same results for women over 50? 

What Happens to Women’s Bodies After 50?

Around the age of 50, women’s bodies undergo a series of changes due to menopause. The natural decrease in estrogen and progesterone production levels triggers alterations throughout the body.

Hormonal Fluctuations

A decrease in estrogen and progesterone levels subjects women to emotional roller coasters, from mood swings and hot flashes to alteration of usual sleep patterns.

Shifts in Metabolic Activity

Muscle protein synthesis and breakdown are also affected, resulting in muscle withering. A decrease in muscle mass leads to less burning of calories and a noticeable change in fat distribution.

Bone Density Loss

Estrogen is a key hormone in maintaining bone health. A drop in it leads to increased bone density loss, elevating the risk of developing osteoporosis or arthritis and making women more vulnerable to fractures.

Susceptibility to Heart Disease

Cholesterol and blood vessel function are also influenced. Estrogen promotes vasodilation and has antioxidant and anti-inflammatory effects. Less of this hormone leads to a downfall in cardiovascular health. 

Health Benefits of Fasting for Women Over 50

Intermittent fasting did not gain renown solely by word of mouth, research on IF also shows health benefits. It has proven to help with:

Weight Loss

IF gained significant popularity among women over 50, mainly due to showing effective results when it comes to weight loss. It works by encouraging the body to use stored energy as a resource since there is less calorie consumption.

Cellular Repair

Promotes cellular renewal, known as autophagy, by removing damaged parts to maintain healthy cells. 

Reduce the Risk of Cancer

On cellular repair, autophagy can help reduce inflammation and restrain tumor growth.

Insulin Sensitivity

Improvement in insulin sensitivity helps regulate blood glucose levels which helps prevent type 2 diabetes.

Mental Health 

Improves neuroplasticity, the brain’s ability to create new neural connections. It enhances brain function, improves mood, diminishes oxidative stress, and has been shown to also help with depression.

How To Do Intermittent Fasting for Women Over 50?

There are plenty of fasting methods available to pick from. Ultimately, the one you choose will depend on your day-to-day routine, eating habits, and which one you feel the most comfortable with. 

5:2 Diet

Works by eating a series of healthy meals for 5 days and then consuming only 500 to 600 calories for 2 days. The days can be any day of the week, however, there must always be a non-fasting day in between them. You have the freedom to decide how and when you eat the allowed daily calories. If you don't want to deal with the hassle, some smartphone apps even set up a daily diet for you.

16/8 Method

Also known as time-restricted eating, it allows eating during an 8-hour window and fasting for 16 hours. There are more variations, like 18/6 or 12/12. Ultimately, you can choose whichever approach best adapts to your everyday routine and eating habits. 

Alternate-Day Fasting

Alternate-day fasting allows you to eat as you normally would one day and entirely fast the next. If you feel like you aren’t ready to undergo a complete fasting day, opt for significantly reducing your calorie intake instead. It is recommended to reduce it to 25% of your regular consumption. Once you feel confident, try fasting entirely.

Circadian Rhythm Fasting

It encourages aligning eating patterns with your body’s internal clock by allowing you to eat during daylight hours and avoiding eating at night. Time-restricted eating during the night aligns with the body’s sleep-wake cycle. The body’s metabolic process peaks during daylight, thus allowing for optimal digestion.

How Many Hours Should a Woman Do Intermittent Fasting?

There isn’t a specific amount of hours women should follow. Your IF schedule will depend on various factors, such as eating habits, existing medical conditions, and your level of commitment. 

Altering your eating times can be a bit confusing. Fortunately, some apps help keep track of your fasting schedule. The Fastic app tailors a fasting schedule specifically for you and sends you helpful reminders throughout the day to ensure you stay on track with your regimen.

Is Intermittent Fasting Good for Women Over 50?

Trying new ways to better your body’s overall health is always encouraged. When done under correct health indications, IF can give you the boost your health needs at 50. And, just like there are advantages, it may also have disadvantages, such as nutrient deficiencies and hormonal imbalances. 

It is advised you consult with your healthcare professional before you start IF. Existing health conditions like diabetes or taking treatment medication may prevent you from practicing IF.

Is It OK to Do Intermittent Fasting During Menopause?

Studies show that IF can positively impact a woman’s health even during menopause. IF can be ideal for some women, but unsuitable for others. No two bodies are the same, and the way a woman’s body reacts to fasting during menopause can be vastly different. Through personalized medical guidance, your doctor will know the safest way for you to do IF during menopause.

Can Intermittent Fasting Cause Early Menopause?

Although IF does influence hormone production levels, it is not known to cause early menopause. Menopause is a natural biological process, so whether you practice IF or not, your body will eventually go through its natural process.

You Want to Give Intermittent Fasting a Go, What Next?

It's never too late to achieve your ideal body and maintain a healthy lifestyle once over 50. So, how do you start? Adapting your new IF routine to your lifestyle can be smooth sailing when you have an intermittent fasting app to assist you. With the right tools, you can successfully find the IF method that best adapts to you.
