What Is Intermittent Fasting?

Intermittent fasting isn’t a “diet” in the traditional sense—it’s a structured eating pattern that alternates between periods of eating and fasting. Instead of focusing on what you eat, IF focuses on when you eat.

From a scientific perspective, fasting triggers changes in your body at the cellular level. During a fast, insulin levels drop and your body shifts from using glucose (sugar) as its main fuel source to burning stored fat. This process supports weight management, reduces inflammation, and may even promote longevity.

Popular methods include:

• 16/8 schedule: Fast for 16 hours, eat within an 8-hour window (often noon–8 p.m.).
• 14/10 schedule: Fast for 14-hours, eat within a 10-hour window.
• 5:2 method: Eat normally for five days, then reduce calories (around 500–600) for two days.
• Alternate-day fasting: Fast every other day.
• Eat-Stop-Eat: A full 24-hour fast once or twice per week.

Each plan has pros and cons, and the best option depends on your body, goals, and lifestyle.

The Benefits of Intermittent Fasting

Research supports several benefits of intermittent fasting for both metabolic health and longevity.

1. Supports Weight Loss

By limiting eating windows, IF naturally reduces calorie intake and encourages the body to burn fat for fuel. Multiple studies show adults can lose 3–8% of body weight in just 3–6 months through consistent fasting routines.

2. Improves Insulin Sensitivity

Fasting helps lower blood sugar and insulin levels—some studies suggest by as much as 30%—which supports metabolic health and may reduce the risk of type 2 diabetes.

3. Enhances Heart and Brain Health

Regular fasting can improve cholesterol levels and reduce markers of inflammation. Many patients also report improved focus and mental clarity during fasting periods.

So, does intermittent fasting really work? Yes—scientific evidence and patient experiences both support its effectiveness when done safely and consistently.

Intermittent Fasting for Weight Loss

Unlike strict calorie-counting diets, intermittent fasting helps regulate hunger hormones naturally. By shortening the eating window, people often eat less without feeling deprived.

A 2020 review of over a dozen clinical trials found IF to be as effective as continuous calorie restriction for weight loss—and easier to maintain long term. However, results vary. A steady, realistic goal is to lose 1–2 pounds per week with proper hydration, balanced nutrition, and consistency.

At Carolina Pharmacy, our pharmacists can guide you in choosing an IF plan that complements your medications and lifestyle.

Intermittent Fasting for Women

Women may respond differently to fasting due to hormonal variations. Extended fasting can sometimes affect menstrual cycles or energy levels. Research suggests women may benefit from gentler schedules like the 14/10 schedule (14-hour fast, 10-hour eating window).

If you’re a woman exploring intermittent fasting, start gradually and listen to your body. Carolina Pharmacy’s care team can help ensure your approach supports—not disrupts—your hormonal and nutritional needs.

How to Fast Safely

Here are practical steps for fasting the healthy way:

• Start slowly: Begin with shorter fasting windows and extend as your body adjusts.
• Stay hydrated: Drink water, herbal tea, or black coffee during fasting hours.
• Break your fast gently: Start with nutrient-rich foods like fruit, protein, or soup.
• Avoid overcompensating: Don’t binge during eating windows.
• Consult your pharmacist or provider: Especially if you take medications for diabetes, blood pressure, or thyroid health.

If you experience fatigue, dizziness, or mood changes, it may be time to pause or adjust your plan. Everyone’s body responds differently.
