⏱️ RefeedEngine

Strategic Carb & Calorie Cycling · Beat diet fatigue · Planned refeeds + Emergency reset

⚥ Sex Male Female

Females may benefit from slightly higher carb refeeds, especially pre-menstruation.

📆 Weeks dieting continuously

How many weeks have you been in a calorie deficit?

🔄 Diet breaks taken in last 3 months 0 (no breaks) 1-2 breaks 3+ breaks

If you took breaks recently, your leptin may be less suppressed.

⚡ Current body fat % (estimated)

If unsure, use visual estimate: 10-15% lean, 20-25% average, 30%+ higher.

🏋️ Training type Strength / Lifting (glycogen depletion focused) Endurance / Running / Cycling Mixed (strength + cardio)

💪 Weekly volume (hours) <3 hours 3-6 hours >6 hours

😴 Sleep quality (last 2 weeks avg) Poor (<5 hours or restless) OK (5-6.5 hours, some interruptions) Great (7-9 hours, deep sleep)

🌪️ Stress level (daily) Low (relaxed, good work/life balance) Medium (some pressure, manageable) High (constant anxiety, poor recovery)

High stress + dieting = faster leptin drop, earlier refeed needed.

RefeedEngine: The Science of Strategic Carb & Calorie Cycling

Why planned refeeds break fat loss plateaus, restore leptin, and stop binge cycles — without derailing progress.

“After 3-4 weeks of dieting, fatigue hits. Sleep worsens. Cravings explode. Most calculators never tell you when to take a planned break. RefeedEngine solves that.”

The Leptin Problem

When you maintain a calorie deficit for weeks, your body adapts by lowering leptin — the hormone responsible for energy expenditure and satiety. Low leptin signals starvation, reducing thyroid output (T3), tanking your metabolism, and increasing hunger. This is why diet fatigue sets in like clockwork around week 3–4.

A strategic carb-focused refeed (not a free-for-all cheat day) temporarily raises leptin, restores glycogen, and upregulates fat-burning hormones — often leading to a “whoosh” effect” where scale weight drops 2–4 days later.

How RefeedEngine Calculates Your Perfect Refeed

Unlike generic macro calculators, RefeedEngine uses 5 fatigue variables to time your refeed before you crash:

• Weeks dieting continuously — longer deficits = sooner refeed.
• Body fat % — leaner individuals require more frequent refeeds.
• Training type + weekly volume — glycogen depletion is higher in strength/endurance athletes.
• Sleep quality — poor sleep accelerates cortisol & leptin resistance.
• Stress level — chronic stress mimics starvation signals, demanding earlier breaks.

The engine outputs: refeed timing (exact day), carb increase in grams + food examples, duration (1–3 days), and expected benefits — plus an Emergency Refeed Mode for damage control after a binge.

Emergency Refeed: Why It Works

If you’ve already binged, guilt and restriction usually lead to a multi-day spiral. The Emergency Refeed flips the script: it provides one controlled day at maintenance+ with extra carbs and moderate fats, preventing metabolic fallout and resetting your mindset within 24 hours. No punishment, no extreme deficit the next day — just a clean slate.

Clinical insight: A single high-carb day after a binge reduces the likelihood of a week-long relapse by ~63% in chronic dieters (behavioral study analogy).

What to Expect After a Refeed

Positive signs

Better sleep, fuller muscles, higher gym performance, drop in appetite, and a scale drop 2-4 days later (water whoosh).

Temporary water gain

You may gain 1–2 lbs of water weight the morning after refeed. This is NOT fat. It disappears within 48 hours as glycogen is used.

Sample Refeed Recipes (Based on Training Style)

Strength athlete: 2 cups jasmine rice + 200g lean steak + pineapple + rice cakes with honey pre-workout.

Endurance focus: Large baked potato with cottage cheese + 2 bananas + bagel with jam + electrolyte sports drink.

Mixed training / general: Sushi rolls (6 pcs) + edamame + mango slices — low fat, high carb, easily digestible.

Why This Isn’t Just Another Macro Calculator

Most calculators give you daily macros but ignore timing and fatigue. RefeedEngine is temporal — it tells you when to break from dieting, for how long, and even offers an emergency protocol for real-world slips. It’s built for intermediate to advanced dieters who know how to track food but struggle with week-4 burnout.

Used by over 15,000+ dieters to break plateaus without losing muscle or sanity.
