Intermittent Fasting: Is It Right for You?

I’ve had a few patients come to me asking about intermittent fasting and whether it can help with weight loss. After trying countless diet fads and struggling to see lasting results, many feel discouraged and see intermittent fasting as a new source of hope. 

In this article, I aim to provide both them, and you, with a clear understanding of what intermittent fasting is and whether it’s a suitable option based on individual health needs and goals.

Intermittent Fasting Is Not A Quick Fix

The reality is, intermittent fasting is not an overnight solution, and it affects each person differently. What you should take away from this is that intermittent fasting (often called IF) might work wonders for one person but may not be the best fit for someone else. Key factors to consider when deciding if intermittent fasting is right for you include your lifestyle, medical history, and overall health.

In this article, I discuss how intermittent fasting may fit into a personalised health approach – which Optimal Health can help you with – who might benefit from IF, who should avoid it, what to expect in terms of results, and what you should consider eating during fasting periods.

What Is Intermittent Fasting?

At its core, intermittent fasting is all about assigning specific times when you either completely or partially skip meals. Unlike traditional diets that focus on counting calories, intermittent fasting is more about when you eat rather than what you eat.

Here are some intermittent fasting examples:

  • 12-Hour Fast: This fasting approach often includes your sleep time. So, if you stop eating at 7 p.m. and have breakfast at 7 a.m., you’re naturally fasting for 12 hours.
  • 16/8 Method: This involves fasting for 16 hours and eating during an 8-hour window. Many people find it manageable by skipping breakfast and eating between 12 p.m. and 8 p.m.
  • 5:2 Diet: With this method, you eat normally for five days a week and limit your calorie intake to around 500-600 on two non-consecutive days.
  • Alternate-Day Fasting: You alternate between regular eating days and either full fasting or significantly cutting calories on fasting days.
  • 24-Hour Fast (Eat-Stop-Eat): This involves fasting for a full 24 hours once or twice a week.
  • The Warrior Diet: A more restrictive approach where you fast for around 20 hours and eat all your daily calories within a 4-hour window.

Who Should Not Do Intermittent Fasting?

While intermittent fasting can have benefits for some, it’s not recommended for everyone. In particular, intermittent fasting may not be suitable for:

  • Young children and teenagers
  • Pregnant or breastfeeding women
  • Those with a history of eating disorders
  • Individuals taking medications that require regular food intake

If any of these apply to you, please consult a healthcare professional before considering intermittent fasting. At Optimal Health, we take an individualised approach to ensure that any dietary changes support – not compromise – your well-being.

How Long Does It Take to See IF Results?

Results from intermittent fasting often vary from person to person. You may notice changes in energy levels, mental clarity, and mild weight loss within four to eight weeks. However, more significant improvements in your metabolic health can take several months of consistency.

At Optimal Health, we take an evidence-based approach, closely monitoring progress through personalised assessments and blood tests to determine whether fasting is working for you and making adjustments where necessary.

The impact of intermittent fasting depends on individual health goals. Research suggests that fasting may contribute to:

How to Do Intermittent Fasting Safely

If you’re considering intermittent fasting, here are some tips to ensure you do it in a way that supports your health:

  • Begin with a 12-hour fast and slowly increase your fasting window over time.
  • Drink plenty of water and non-caloric beverages during fasting periods.
  • During your eating window, prioritise whole, balanced meals with lean proteins, healthy fats, and fibre-rich foods.
  • If you experience dizziness, extreme fatigue, or any concerning symptoms, consult a health professional. The key is to listen to your body.
  • Everyone responds differently to intermittent fasting. At Optimal Health, we assess your unique needs and guide you towards a plan that aligns with your overall well-being.

What Foods Can You Eat During Intermittent Fasting?

For the best results with intermittent fasting, focus on whole, nutrient-rich foods during your eating windows. 

A well-balanced diet can help stabilise energy levels and keep you feeling full longer. In particular, prioritising protein and fibre can help maintain satiety, support energy levels, and reduce hunger during fasting hours. Here’s what to prioritise:

  • Fruits & Vegetables: Apples, berries, oranges, leafy greens, broccoli, and cucumbers
  • Whole Grains: Quinoa, rice, oats, barley, and buckwheat
  • Healthy Fats: Olive oil, avocados, nuts, and seeds
  • Proteins: Eggs, fish, poultry, legumes, and lean meats
  • Fibre: Lentils, chickpeas, oats, chia seeds, and a variety of vegetables
  • Beverages: Water, unsweetened tea, and black coffee (helps curb hunger and keeps you hydrated)

Try to limit ultra-processed foods like sugary drinks, deep-fried snacks, and pre-packaged meals, as they can cause energy crashes and make fasting more challenging.

Are There Risks to Intermittent Fasting?

Intermittent fasting isn’t for everyone, and it should be approached with caution. Some people may experience:

  • Increased hunger and irritability, especially in the early stages
  • Disrupted sleep patterns
  • Nutrient deficiencies, if not balanced properly

And most importantly, if you have a history of heart disease, metabolic conditions, or take medications that require food intake, it’s critical that you undergo a full assessment with us prior to making any dietary changes.
