5 Best Intermittent Fasting Methods for Women Over 40

THÙY DƯƠNG (THEO HEALTHSHOTS) |

According to Healthshots, women over 40 years old can still lose weight well if they properly apply the 5 intermittent fasting (IF) methods below.

Method 12:12

In this method, you will fast for 12 hours and eat within the next 12 hours. This is a gentle fasting method that is ideal for beginners and people with hormonal imbalances.

For example, you would start eating between 8am and 8pm and fast overnight.

Method 14:10

In this method, you need to fast for 14 hours and eat within 10 hours. This method will be more advanced than 12:12, which helps to increase insulin sensitivity better.

For example, you will start eating at 10am and finish your meals at 8pm.

16:8 Method

In this method, you need to fast for 16 hours and eat within 8 hours. This is the most popular IF method, helping to lose fat and increase metabolic flexibility.

For example, in the 16:8 method, you would start eating from 12 noon to 8 pm. This intermittent fasting method is great for people who are used to fasting.

Crescendo fasting

For women over 40, crescendo fasting is the best intermittent fasting method to use. In this method, you will fast for 12-16 hours a few days a week. This flexible eating method is ideal for women who are older and experiencing hormonal changes.

For example, you can fast for 12–16 hours every other day instead of fasting every day.

Method 5:2

On this method, you eat normally for 5 days and restrict your calories to 500-600 for 2 days. This method is effective for weight loss and insulin resistance, but may not be suitable for people who are sensitive to calorie deficits.

Who should not do intermittent fasting after 40?

While intermittent fasting is safe for women over 40, there are some people who should not do it.

People with diabetes or hypoglycemia: IF can cause blood sugar fluctuations, which can be dangerous for people with diabetes or those prone to hypoglycemia.

People with eating disorders or a history of eating disorders: Fasting can worsen unhealthy eating behaviors such as binge eating or obsessive eating about food.

Women with adrenal disease or chronic stress problems: Fasting can increase cortisol (the stress hormone), making fatigue and stress-related symptoms worse.

Women who are underweight or have nutrient deficiencies: IF may lead to more weight loss and make deficiencies worse.

Pregnant or breastfeeding women: Nutritional needs are higher during these periods, making fasting unsuitable.
