I’ve introduced a weekly Sunday night to Tuesday lunch fast into my routine. Here’s what GROK thinks:
From Sunday 8:00 PM to Tuesday 1:23 PM is 41 hours and 23 minutes.Quick breakdown:Sunday 8:00 PM → Monday 8:00 PM = 24 hours
Monday 8:00 PM → Tuesday 8:00 PM = 24 hours
→ subtotal so far: 48 hours to Tuesday 8:00 PM
Then subtract the extra time from Tuesday 8:00 PM back to 1:23 PM
(8:00 PM – 1:23 PM = 6 hours and 37 minutes earlier)
So: 48 hours − 6 hours 37 minutes = 41 hours 23 minutesAlternatively (direct calculation): Sunday 8 PM to Tuesday 8 PM = 48 hours
Tuesday 8 PM to Tuesday 1:23 PM = go back 6 hours 37 minutes
→ 48 − 6:37 = 41 hours 23 minutes
Total: 41 hours and 23 minutes (or exactly 41.3833… hours if you want it in decimal form).
Health benefits of such a length water fast plus add 30sec dead hanging daily, 10lbs overhead ball bounce x30 daily, plus 6 miles on snow trails with crampons *30F
A 41-hour water fast (from Sunday 8 PM to Tuesday 1:23 PM) combined with your described daily activities—30 seconds of dead hanging, 30 overhead ball bounces (interpreting this as explosive medicine ball overhead throws or slams with a 10-lb ball), and 6 miles of snow trail walking in 30°F conditions—can offer several potential health benefits, primarily around metabolic health, fat loss, cellular repair, strength/mobility gains, and cardiovascular improvements.This routine blends short-term fasting with light-to-moderate exercise in a cold environment, which research suggests can enhance fat-burning and other adaptations. However, benefits are most pronounced in healthy individuals, and exercise during fasting (even short fasts like this) should be approached cautiously—stick to low-to-moderate intensity, listen to your body, and prioritize hydration/electrolytes (e.g., add a pinch of salt to water if needed). Strenuous activity isn’t ideal during fasting due to reduced glycogen and potential fatigue.Key Potential BenefitsEnhanced Fat Loss and Metabolic Shift
A ~41-hour fast depletes glycogen stores (typically after 12–24 hours), shifting your body to burn fat for fuel (ketosis begins). This promotes weight loss (mostly water/glycogen initially, then fat) and improves insulin sensitivity. Adding exercise amplifies this: the 6-mile cold walk increases calorie burn (cold exposure boosts energy expenditure to maintain body heat, potentially activating brown fat for extra calorie use), while the explosive ball work and hangs add metabolic demand. Overall, this combo can accelerate fat oxidation compared to fasting or exercise alone.
Autophagy and Cellular Repair
Fasting for 24–72 hours ramps up autophagy (cells recycling damaged parts), linked to reduced inflammation, better longevity, and lower chronic disease risk (e.g., heart disease, diabetes). Exercise (especially endurance like walking) may enhance this process mildly. Short fasts like yours show promise for these benefits without the risks of longer ones.
Cardiovascular and Blood Pressure Improvements
Short fasts can lower blood pressure, cholesterol/triglycerides, and improve heart metrics. The 6-mile snowy trail walk in cold weather adds cardio benefits: cold exposure may improve endurance, vascular health, and mood while burning more calories than in warm conditions. This low-impact activity supports heart health without over-stressing a fasted state.
Shoulder Mobility, Posture, and Grip Strength (from Dead Hangs)
Daily 30-second dead hangs decompress the spine, stretch shoulders/back, relieve tension, and build grip/forearm strength. They improve posture (countering slouching), enhance shoulder stability/mobility, and may reduce upper-body tightness. In a fasted state, this low-impact move is generally safe and feels great for recovery.
Explosive Power, Core Strength, and Full-Body Conditioning (from Overhead Ball Work)
30 reps of overhead ball bounces/throws/slams engage your full body explosively: core, shoulders, glutes, legs, and back. This builds power, boosts heart rate (HIIT-like effect for cardio health), improves coordination, and burns calories. It’s a great metabolic conditioner that complements fasting’s fat-burning mode.
Mental and Mood Benefits
Cold-weather walking in nature reduces stress, boosts endorphins, and enhances mental clarity/resilience. Fasting can increase BDNF (brain-derived neurotrophic factor) for better cognition/mood. Combined, this routine may leave you feeling energized and accomplished (many report mental sharpness during short fasts + light activity).
Overall Resilience and Immune Support
Cold exposure + moderate exercise + fasting may strengthen immune response (some studies link short fasts to better viral defense) and build mental toughness.
Important Caveats and Safety NotesEnergy and Performance: At 41 hours, you may feel fatigued, lightheaded, or weaker (glycogen depletion + cold stress). The walking is fine (encouraged as low-intensity), but scale back if dizzy. Dead hangs and ball work are short/low-volume, so they’re likely okay if you feel good—avoid pushing to failure.
Risks: Dehydration (fasting + cold/dry air), electrolyte imbalance, or low blood sugar could occur. Refeed carefully post-fast (start light). Not suitable if you have conditions like diabetes, eating disorders, or are pregnant/underweight.
Individual Variation: Benefits are evidence-based for short fasts + moderate exercise, but results vary. Consult a doctor before combining fasting with activity, especially if new to either.
This is a solid, challenging routine for metabolic reset and functional fitness in winter—stay hydrated, monitor how you feel, and enjoy the process! If you notice any adverse effects (e.g., extreme fatigue, dizziness), break the fast early.

How about breaking the fast with 3 dates, and a handful of macadamia nuts followed an hour later with raw yogurt, berries and toasted walnuts
Breaking a 41-hour water fast (a moderate extended fast) with your proposed sequence—3 dates + a handful of macadamia nuts first, then raw yogurt with berries and toasted walnuts about an hour later—is a solid, nutrient-dense approach overall. It’s far gentler and more thoughtful than jumping into a big meal, aligning well with common recommendations for short-to-moderate fasts (under 72 hours). Refeeding syndrome risk is very low here (it’s mostly a concern for much longer fasts or severe malnutrition), but the key is still easing digestion, stabilizing blood sugar, and replenishing electrolytes/nutrients without overwhelming your gut.Why This Works Well (Benefits)Dates as the opener: Traditionally excellent for breaking fasts (e.g., in many cultural/religious practices like Ramadan). They provide quick natural sugars (fructose/glucose) for gentle energy restoration, plus potassium, magnesium, and fiber to help with electrolyte balance and mild rehydration. 3 dates (~60–75 calories, 15–20g carbs) give a controlled, not overwhelming, blood sugar bump—much better than a sugary processed item.
Handful of macadamia nuts: Great follow-up. Macadamias are very low-carb (2g net per oz), high in healthy monounsaturated fats (heart-healthy, anti-inflammatory), and provide sustained energy without spiking insulin much. They add electrolytes (magnesium, potassium), support satiety, and are often recommended by fasting experts (e.g., Dr. Jason Fung suggests a few macadamias or similar nuts to break fasts). A small handful (1 oz/28g, ~200 calories) is digestible for most and pairs nicely with dates’ sweetness to blunt any minor glucose rise.
Delayed yogurt + berries + toasted walnuts (1 hour later): Smart timing—gives your digestive system ~60 minutes to “wake up” after the initial solids. Raw yogurt (assuming full-fat, live cultures) introduces probiotics for gut health, easy-to-digest protein, and calcium. Berries add antioxidants, low-glycemic carbs, fiber, and vitamins (e.g., vitamin C) without excess sugar. Toasted walnuts bring omega-3s (anti-inflammatory), more healthy fats, and crunch/texture. This combo creates a balanced mini-meal: protein + fat + fiber + moderate carbs, which supports stable energy, muscle repair, and continued metabolic benefits from the fast.
Overall perks of this refeed:Nutrient replenishment: Covers quick carbs, healthy fats, protein, fiber, probiotics, electrolytes, and micronutrients.
Blood sugar control: Low-GI elements (fats/fiber from nuts/yogurt) moderate the dates’ natural sugars.
Gut-friendly: Starts small/simple, then adds fermented/digestible foods—reduces bloating, cramps, or nausea risk.
Maintains fasting momentum: Keeps things low-processed, whole-food focused, preserving insulin sensitivity gains.
Potential Drawbacks and Tips to OptimizeDigestion notes: Nuts (especially macadamias) are fatty and can be slower to digest for some after fasting—rarely cause issues in small amounts, but if you’ve had trouble with high-fat foods before, start with fewer (e.g., 5–10 nuts). Dates’ fiber might cause mild bloating if you’re sensitive.
Portion awareness: Keep the handful small (1 oz max) to avoid overdoing calories/fats right away. Total first bite: ~300–400 calories; second: similar—perfect for easing in.
Hydration/electrolytes: Sip water (or add a pinch of sea salt) before/during. If you felt low-energy during the fast, consider bone broth or electrolyte drops earlier if needed.
Listen to your body: Eat slowly, chew well. If you feel full, nauseous, or off, stop and wait longer. Most people feel great with this style after 40-ish hours.
Next steps post-refeed: Proceed to normal meals gradually—add steamed veggies, lean proteins, etc., over the next 12–24 hours. Avoid heavy/processed foods initially.
This is a thoughtful, effective way to transition—many fasters report feeling energized and clear-headed with similar fruit + nuts + dairy/fermented combos. If you have any digestive sensitivities or health conditions, check with a doctor, but for a healthy person, this looks spot-on. How did the fast feel overall?
