Your Summer Reset, Part 2: Why Time-Restricted Eating Can Transform Your Metabolism
Summer is in full swing—and whether you’re traveling, soaking up the sun, or just looking for more energy to enjoy it all, it’s a great time to reset your metabolic rhythm. One of my favorite strategies to support energy, weight loss, and hormone balance?
Time-Restricted Eating (TRE).
Unlike traditional diets that focus on what you eat, TRE focuses on when you eat—and it can have a profound impact on your health and metabolism, especially when combined with snack elimination (see Part 1).
What Is Time-Restricted Eating?
Time-Restricted Eating is an eating pattern that confines your meals to a set window of time each day—typically between 6 and 12 hours—with fasting outside of that window. You’re not necessarily eating less, just eating within a defined period that aligns with your body’s natural circadian rhythm.
Popular TRE patterns include:
16:8 TRE: Eat during an 8-hour window (e.g., 10 AM–6 PM), fast for the other 16 hours
14:10 TRE: Eat within 10 hours, fast for 14.
12:12 TRE: Eat and fast for 12 hours each—great for beginners or maintenance.
TRE is simple, sustainable, and adaptable to your lifestyle, which makes it easy to maintain over time.
How Time-Restricted Eating Supports a Healthy Metabolism
1. Improves Insulin Sensitivity and Glucose Control
TRE helps regulate blood sugar by enhancing insulin function, especially when meals are consumed earlier in the day.
This lowers the risk for type 2 diabetes and supports more efficient fat burning.
2. Promotes Weight Loss and Reduces Belly Fat
TRE naturally limits late-night snacking and reduces overall calorie intake—without restriction.
It encourages the body to use stored fat for fuel, especially visceral (belly) fat, which is linked to hormonal imbalance and inflammation.
3. Aligns with Your Circadian Rhythm
Eating during daylight hours optimizes metabolism and hormone cycles (like cortisol, insulin and melatonin).
Late-night eating disrupts these rhythms, impairing glucose tolerance and fat metabolism.
4. Triggers Cellular Repair and Longevity Mechanisms
Fasting periods activate autophagy, the body’s natural cellular cleanup system.
This supports healthy aging, reduces inflammation, and enhances tissue repair—especially important during midlife hormonal transitions.
5. Boosts Hormonal and Mitochondrial Resilience
TRE supports a better balance of leptin, insulin, and growth hormone—key regulators of metabolism, hunger, and energy.
It also enhances mitochondrial function, improving energy levels and fat oxidation.
6. Improves Gut Health and Microbiome Diversity
TRE gives your digestive system time to rest between meals.
This improves microbiome diversity, reduces gut inflammation, and supports a stronger metabolic foundation.
7. Reduces Chronic Inflammation
TRE has been shown to reduce markers of systemic inflammation, including hs-CRP and inflammatory cytokines.
This is especially helpful for women, as inflammation plays a major role in weight gain and hormone disruption
How to Get Started
If you're new to TRE, I recommend starting with a 12:12 or 14:10 window for at least 1 to 2 weeks. As your body adjusts, you can experiment with a 16:8 window for faster results—but avoid doing this indefinitely. Once you've reached your goals, transition to a more moderate schedule to maintain balance and avoid depletion.
Pro Tip: An earlier eating window (like 8 AM–4 PM) provides the most metabolic benefit. Try to finish eating 2–3 hours before bedtime.
Important: If you’re pregnant, nursing, have adrenal issues, a history of eating disorders, or complex metabolic conditions, always consult your practitioner before trying TRE.
Pair It with Pro Tip #1
Combining Time-Restricted Eating with no snacking between meals (Summer Reset Part 1) is a powerful duo for restoring insulin sensitivity, promoting fat burning, and rebalancing hormones. These foundational shifts can dramatically improve how you feel in just a few weeks.
