Intermittent Fasting for Seniors

As we age, our body’s needs change, requiring us to adapt care routines and modify lifelong habits. Can intermittent fasting be an option to maintain good health? 

Intermittent fasting is renowned for its health benefits both internally and externally. Scientific research and numerous personal accounts have demonstrated its effectiveness, not only in enhancing health but also as a potential treatment for neurodegenerative diseases. With all this promising information, can fasting offer the same benefits to seniors?

Let’s explore how intermittent fasting can improve your health as a senior and the key considerations to keep in mind if you decide to adopt this practice at this stage of your life.

How Does Intermittent Fasting Work?

Intermittent fasting consists of alternating eating and fasting periods throughout the day. During fasting periods, you can consume only zero-calorie beverages, while during eating windows, you eat whatever you want. 

Types of intermittent fasting methods:

• Time-restricted eating: Limit food intake during specific periods during the day, such as the 16:8 method, where you fast for 16 hours and eat during an 8-hour window.

• 5:2 diet: Eat as you normally would for five days and restrict calorie intake to 500-600 calories on two non-consecutive days. 

• Alternate-day fasting: Alternate between days of normal eating and days of fasting, where you must fast for the entire 24 hours of a day.

• Extended fasting: No food intake for 24 hours or more. During this time, you can only drink zero-calorie beverages, such as water, fruit-infused water, sugar-free herbal teas, and any other zero-sugar electrolyte drink.

What Are the Benefits of Intermittent Fasting for Seniors?

Intermittent fasting offers numerous health benefits for seniors. A scientific analysis found that fasting for 7 to 21 days can efficiently control rheumatic diseases, chronic pain syndromes, hypertension, and metabolic syndromes. 

Additional benefits of intermittent fasting for seniors include:

• Improved insulin sensitivity

• Boosted digestion and metabolism

• Promotion of better quality sleep

• Enhanced cognitive function and memory

• Reduced risk of heart diseases

• Stabilized blood sugar levels and reduced risk of type 2 diabetes

• Assistance in weight management

• Improved bone health

• Promotion of longevity and autophagy, and reduction of inflammation

A review on intermittent fasting stated that physiological alterations linked with fasting have profound implications for pathological mechanisms associated with dementia, particularly, Alzheimer’s disease. This points to the hypothesis that fasting over the years will potentially reverse or delay the pathological process of Alzheimer’s disease.

Moreover, an investigation on the effects of Ramadan fasting on serum bone profile demonstrated that fasting could boost bone health by influencing the secretion of parathyroid hormone (PTH). PTH plays a vital role in calcium and phosphate metabolism and the bone remodeling process.

Intermittent Fasting for Seniors Over 70

When contemplating intermittent fasting for seniors over 70, unique nutritional needs and existing medical conditions must be considered. Seniors should prioritize adequate nutrient intake during eating windows to support overall health. Moreover, consulting with a healthcare provider for safe indications and considerations is essential, particularly when taking medications that may be impacted by fasting.

Intermittent Fasting for Senior Women

A six-week intermittent fasting intervention on women over 60 years of age resulted in positive changes in body composition. Following a 16:8 fast, subjects reported an average body fat loss of about 4.5 pounds.

How to Start and Maintain an Intermittent Fasting Routine?

Tips on how to start intermittent fasting and successfully integrate it into your lifestyle.

Gradual integration of the fasting routine

Be gentle on your body as it adjusts to the changes. Slowly introduce fasting with long eating windows and gradually lengthen the fasting periods.

Stay hydrated and balanced nutrient intake

Proper hydration levels ensure healthy fasting. Your body needs more water than usual to compensate for water not obtained from food. Follow a nutrient-rich diet with fruits, vegetables, whole grains, and lean proteins to provide sufficient energy during fasting hours. See a nutritionist to tailor a diet plan that meets your unique nutritional needs. Keep track of your hydration levels at all times with the Fastic app. Its useful fluid tacker tool lets you know if you are giving your body the fluids it needs during fasting.

Monitor energy levels and regular health check-ups

Make sure you are on top of your body’s reaction to fasting. Take note of unusual reactions and consult with your doctor frequently to guarantee an effective and safe fast.

Physical activity and mindful practices

Low-intensity exercises are ideal to promote the effects of fasting. Practicing yoga, walking, and swimming are excellent ways to stay active. Mindful practices such as meditation and deep breathing are great to lessen the stress fasting may cause on your body. 

16:8 Intermittent Fasting for Seniors

The 16:8 intermittent fasting method is the most popular, particularly among senior individuals. This fasting method adapts well to an everyday routine. Both the duration of the eating window and the fasting period is long enough to foster fasting effects and simultaneously, allow enough time during the day to have a regular eating schedule. 

16:8 Intermittent Fasting for Seniors Schedule

There is no best intermittent fasting regimen for seniors; while there are intermittent fasting charts based on age, their reliability is uncertain. We recommend a 16:8 intermittent fasting for seniors. Here is an example of how a 16:8 fast schedule can be structured for seniors.

• 9:00 AM: Break your fast with a zero-calorie beverage.

• 10:00 AM Eat a nutrient-dense breakfast.

• 12:00 PM: Have a light snack.

• 2:00 PM: Eat a light snack.

• 4:00 PM: Enjoy an abundant meal to prepare for the fasting period.

• 5:00 PM: Begin fasting.

Remember! You can adjust it to fit your hunger cues and daily responsibilities, with the number of snacks and meals entirely up to your preference. 

Possible Risks of Intermittent Fasting for Seniors Over 70

Nutrient deficiencies

Limited eating hours may lead to nutrient deficiencies, especially if diet modifications (when necessary) are not made. As the body’s ability to absorb nutrients decreases with age, ensuring adequate nutrient intake during eating windows is imperative. Insufficient vitamins and minerals may weaken the immune system, and lead to bone health issues. Ask your doctor if supplements are a good option for you.

Blood sugar fluctuations

Fasting may lead to blood sugar fluctuations, especially in those with diabetes or prediabetes. Seniors must monitor their blood sugar levels frequently and be able to identify blood sugar imbalance symptoms. Include complex carbohydrates, proteins, and healthy fats to sustain stable blood sugar levels.

Muscle loss

As humans age, it is normal to lose muscle mass, and fasting can encourage this even more if protein intake is insufficient. Maintaining healthy muscle mass is needed for balance, mobility, and overall strength. Intermittent fasting in men over 40 is common, as it helps preserve muscle mass. Besides eating adequate protein, doing low-intensity exercises is also recommended. Regular strength-training exercises help preserve muscle mass during fasting.
