This comparison does not assign a generated winner or score.
- Morning (6–8 a.m. fasted)
- Severe hunger 8 a.m.–12 p.m., high carb cravings
- GH pulse 9–10 a.m. (overlaps with natural cortisol peak. Wasted synergy)
- Minimal. High insulin from breakfast blocks FFA oxidation
- No disruption
- Low. Appetite spike makes fasting or controlled intake nearly impossible
- Midday (12–2 p.m. with lunch)
- Moderate hunger 2–6 p.m., evening snacking likely
- GH pulse 2–3 p.m. (suboptimal. Insulin elevated from meal)
- Low. Postprandial insulin prevents lipolysis for 4–6 hours
- Moderate. Manageable but suboptimal metabolic alignment
- Evening (8–9 p.m., 2–3 hrs post-dinner)
- Mild hunger 9–10 p.m., clears before bed
- GH pulse 9:30–10:30 p.m. (aligns with natural nocturnal GH secretion)
- Peak 2–6 a.m. during fasted sleep. Maximum FFA oxidation
- Minimal disruption if dosed 90+ min before sleep
- High. Best balance of hunger management, lipolysis, and circadian rhythm
- Immediately before bed (10–11 p.m.)
- Severe hunger 11 p.m.–1 a.m., frequent night waking
- GH pulse midnight–1 a.m. (overlaps with natural pulse but hunger disrupts sleep)
- Moderate. Lipolysis occurs but sleep disruption reduces net benefit
- Moderate to severe disruption. Ghrelin-induced waking common
- Low. Sleep quality loss outweighs lipolytic benefit
- Professional Assessment
- Evening dosing 2–3 hours post-meal is the only timing that sustains adherence, maximizes nocturnal lipolysis, and preserves sleep architecture. Morning and pre-bed dosing both fail on practical adherence. You can't maintain a protocol you can't tolerate daily for 16+ weeks.
