Ask an Agebreaker: Intermittent Fasting

Top Community Questions Answered

Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating, without prescribing specific foods but focusing on when you eat them . Studies suggest IF can aid weight loss, improve insulin sensitivity, reduce inflammation, and support heart and brain health . Common methods include the 16:8 approach—fasting for 16 hours and eating within an 8-hour window—and the 5:2 plan, which involves two non-consecutive 24-hour fasts each week . Research shows starting gradually—beginning with a 12-hour fast and slowly increasing your fasting window—helps your body adapt comfortably. Below are the top three questions from our community, with simple, actionable advice to help you succeed.

1. How do I start intermittent fasting safely?

Action Steps:

▶ Begin with a 12:12 schedule. Start by fasting from 7 pm to 7 am, most of which overlaps with sleep, then gradually extend your fast by 1–2 hours each week until you reach 16:8 (U-M School of Public Health).

▶ Pick the right IF method for your lifestyle. If daily fasting feels too strict, try alternate-day fasting or a 5:2 plan, which may offer similar benefits without daily time constraints (Healthline).

▶ Plan your meals. Schedule your eating window around your social and work commitments to ensure consistency and reduce temptation (Verywell Health).

▶ Listen to your body. If you feel dizzy or excessively tired, shorten your fast or add light snacks until you adapt (Hopkins Medicine).

2. What should I eat during my eating window?

Action Steps:

▶ Focus on nutrient-dense foods. Prioritize lean proteins (eggs, fish), high-fibre vegetables, healthy fats (avocado, nuts), and whole grains to stay full longer and support muscle maintenance (Medical News Today).

▶ Balance macros at each meal. Aim for a plate with one-third protein, one-third starch or grain, and one-third vegetables to stabilize blood sugar and energy levels (Health).

▶ Avoid empty calories. Limit sugary snacks, processed foods, and soft drinks, which can spike insulin and undermine fasting benefits (Harvard Health).

▶ Stay flexible. If you have a social event, adjust your window rather than skipping meals, keeping overall weekly fasting hours consistent (Dietitians Australia).

3. How do I manage hunger and stay hydrated?

Action Steps:

▶ Hydrate constantly. Drink water, herbal tea, or black coffee during fasting periods to curb hunger pangs and maintain electrolyte balance (Medical News Today).

▶ Use distractions. Engage in light activities—reading, walking, or gentle yoga—to take your mind off food (Medical News Today).

▶ Rest when needed. Avoid strenuous exercise during early fasting days; light movement only until your energy stabilizes (Medical News Today).

▶ Track your progress. Use a simple fasting app or journal to note how you feel, which helps identify the best routine for your body.
