Going for my first 36 hours. Any tips — what do certified weight loss coaches recommend?

Preparing Mentally and Physically for Your First 36-Hour Fast

As a certified weight loss coach with over 15 years helping midlife adults, I know the first 36-hour fast can feel intimidating—especially when hormonal changes and past diet failures make you skeptical. In my book The Metabolic Reset Protocol, I emphasize starting with a clear plan. Begin your fast after dinner on day one and aim to eat again at breakfast on day three. This gives your body time to shift into fat-burning mode while keeping it manageable for beginners.

Focus on hydration from the start. Drink at least 3 liters of water daily, adding a pinch of high-quality sea salt or using an electrolyte packet with 500-1000mg sodium, 200-400mg potassium, and 50-100mg magnesium. These numbers prevent the headaches and fatigue common in early fasting, particularly when managing blood pressure or diabetes alongside weight loss.

Managing Hunger, Energy, and Joint Pain During the Fast

Hunger peaks usually hit between hours 12-18 and again around hour 30. When this happens, sip bone broth (under 50 calories) or black coffee with a teaspoon of MCT oil. These keep insulin low without breaking the fast. For joint pain that makes movement tough, gentle walks of 10-15 minutes or stretching help release stored energy without strain. Most clients report joint discomfort eases after 24 hours as inflammation drops.

Expect possible fatigue or irritability. Rest more than usual—no intense workouts. Track blood sugar if you have diabetes; many see stabilization after the initial adjustment. In The Metabolic Reset Protocol, I outline how consistent shorter fasts build tolerance before attempting 36 hours.

Breaking Your Fast Safely and What to Eat After

Breaking the fast is critical. Start with easily digestible foods like a small avocado, bone broth, or steamed vegetables with olive oil. Avoid heavy carbs or large portions that can cause digestive distress. A sample first meal: two eggs scrambled in butter with spinach. This supports stable blood sugar and prevents rebound hunger.

Over the following 24 hours, ease back into normal portions using a high-protein, moderate-fat approach. This prevents the metabolic backlash many experience after past failed diets.

Long-Term Strategy and When to Seek Guidance

Use this first 36-hour fast as data, not a test of willpower. Note energy, mood, and weight changes. Repeat every 1-2 weeks while building sustainable habits like time-restricted eating. If you take medications for blood pressure or diabetes, consult your physician before starting. Certified coaches recommend pairing fasting with stress management and sleep optimization for hormonal balance in your 40s and 50s.

Remember, consistency beats perfection. Thousands have reversed midlife weight gain using these methods without expensive programs insurance won't cover.

💬 What the Community Says

In online forums and support groups, first-time 36-hour fasters often express a mix of excitement and anxiety. Many beginners in their late 40s and early 50s report struggling most with headaches and boredom in the second half, but say proper electrolytes made a noticeable difference. A common theme is surprise at how joint pain and inflammation seemed to improve by hour 24, though some with diabetes shared they monitored glucose closely and adjusted meds with their doctor. The community is split on adding bone broth—some call it essential for beginners while others insist strict water-only is better. Lived experiences highlight that breaking the fast gently prevents the bloating and regret many felt after their first attempt. Overall, participants encourage starting with shorter fasts first, noting that after 2-3 tries the process gets much easier despite initial skepticism from repeated diet failures.
