You can’t eat or sleep because your body is signaling distress - physical or mental. Chronic conditions like cancer cachexia disrupt appetite, while anxiety can cause sleep misperception, making you feel unrested. Start by tracking patterns and implementing small changes like hydrating with bone broth or practicing mindfulness before bed. If symptoms persist, it’s time to dig deeper.
Seek professional help if you’re eating fewer than five bites daily or sleeping less than three hours nightly for over ten days.
Unintentional weight loss of 10% in six months may indicate serious issues like organ failure or chronic illness.
Dark thoughts, yellow eyes, or a heart rate over 100 bpm also warrant immediate attention.
We’ll explore how hormones, nutritional deficiencies, and even your medications - like antidepressants suppressing appetite - could be at play. Let’s uncover actionable solutions to restore your sleep and appetite naturally.
Can’t eat or sleep? Your body’s waving a red flag. Let’s break down the top 5 culprits - physical and mental - and how they hijack your hunger and sleep.
1. Chronic inflammation (like cancer)
Tumors trigger systemic inflammation disrupting hunger signals in 66% of cancer patients, nuking appetite. Your brain literally stops recognizing “I’m hungry” cues. Bonus hell? This same inflammation rewires sleep-regulating brain regions, leaving you exhausted but wired.
2. Depression/anxiety loops
Depression messes with hunger hormones like ghrelin and leptin - ever feel “stomach-hungry” but “brain-not-interested”? That’s anhedonia. Anxiety then amplifies sleep misperception (“I didn’t sleep at all!”…when you actually did), trapping you in exhaustion.
3. Gut issues (GERD, IBS)
Chronic nausea from mitochondrial gut disorders or digestive pain pathways makes eating feel like a chore. Nighttime acid reflux? That’s your insomnia trigger right there - body can’t rest if it’s fighting digestion fires.
4. Thiamine deficiency
Common after bariatric surgery or extreme dieting, thiamine (B1) deficiency causes nausea + appetite loss while scrambling sleep-wake cycles. No B1 = brain can’t make energy, so you’re too fatigued to eat but too malnourished to sleep.
5. Kidney/COPD flare-ups
In kidney disease, protein-energy wasting syndrome tanks appetite. COPD’s labored breathing burns calories fast, making eating feel pointless - and oxygen dips at night jerk you awake repeatedly.
What now?
Track when symptoms hit hardest (morning nausea vs. midnight insomnia?). Small wins matter: sip bone broth if solids revolt, try 10-minute meditation before bed. If this resonates, jump to when to seek professional help or how hormones affect sleep and appetite. You’ve got this.
Seek professional help immediately if:
Don’t wait if you’re post-surgery/on meds: bariatric patients risk thiamine deficiency within weeks, and SSRIs/steroids can nuke appetite and sleep architecture (see Could your medications be the cause?).
Still unsure? Track symptoms for 72 hours. If food aversion persists past 3 days or sleep debt triggers microsleeps (head bobs, zoning out mid-convo), call a doctor. You’re not “overreacting” – 70% of chronic GI cases get diagnosed only after patients insist on deeper testing.
Act now if: You’ve tried 4 prevention tips and lifestyle changes with zero improvement, or relationships/job stability crumble from fatigue. Tomorrow’s too late.
Struggling to eat or sleep? Let’s fix that with four science-backed tweaks you can start tonight.
1. Hack your sleep environment
Keep your bedroom cool (65°F/18°C), pitch-black, and dead silent - use blackout curtains and white noise if needed. Stick to the same bedtime every. single. night, even weekends. Ditch screens 1 hour before bed - blue light butchers melatonin. Bonus: consistent bedtime routines improve sleep quality in children with leukemia works for adults too.
2. Eat to sleep (yes, really)
Load up on walnuts, salmon, or chia seeds - their omega-3-rich diets boosted sleep duration in UK children. Avoid eating within 3 hours of bedtime - heavy late-night meals worsen sleep apnea risks. Struggling with appetite? Try 5-6 tiny meals instead of 3 big ones (more in 5 nutritional deficiencies that cause sleep issues-5).
3. Move strategically
30-minute walks before noon regulate circadian rhythms better than evening workouts. 30-minute daily workouts reduced sleep debt in teens - you’re never too old. Can’t gym? Do 10 air squats every time you pee. Even aerobic exercise eased insomnia in fibromyalgia patients.
4. Crush stress before it crushes you
Try the “4-7-8” breath: inhale 4 sec, hold 7, exhale 8. Repeat 4x. mindfulness programs reduced nighttime awakenings by 30% in high schoolers - works for adults. Still wired? Write tomorrow’s to-do list 2 hours before bed - relaxation exercises helped cancer patients fall asleep faster.
Start with one change tonight. Pair sleep hygiene fixes with stress breathing, or swap late snacks for omega-3s. These aren’t quick fixes - they’re lifelong upgrades. Still stuck? How hormones affect sleep and appetite-4 explains why your biology might be fighting you.
How Hormones Hijack Your Sleep and Hunger
Your hormones are the puppet masters of sleep and appetite - mess with them, and everything falls apart. Here’s exactly how they work (and wreck your nights and cravings):
Fix It Fast:
- Reset circadian rhythms (dim lights by 9 PM, sunlight at dawn).
- Protein-rich breakfasts blunt ghrelin spikes (try eggs or Greek yogurt).
- Walk after meals - even 10 minutes boosts leptin sensitivity.
Struggling with stubborn insomnia or appetite swings? It might tie to nutritional deficiencies (see section 5) or medication side effects (section 6). If cortisol feels permanently stuck on "high," check out natural solutions in section 9.
Bottom line: Hormones don’t play fair. Small tweaks to sleep and meals can rebalance them - start tonight.
5 Nutritional Deficiencies Sabotaging Your Sleep (And How to Fix Them)
If you’re tossing all night, your diet might be missing key nutrients. Let’s break down the deficiencies wrecking your sleep and how to fix them - fast.
Quick fixes: Get bloodwork done (especially iron/B12), tweak meals with the foods above, and check out our hormones section if fatigue persists. Small diet shifts can reboot your sleep *tonight*.
Could your meds be why you can’t eat or sleep? Absolutely. ADHD stimulants, antidepressants, and antipsychotics top the list. Let’s break it down:
1. ADHD meds (like Adderall):
2. Antidepressants (SSRIs/SNRIs):
3. Antipsychotics (olanzapine, quetiapine):
Check your labels for these culprits. Notice changes after starting a new script? Track symptoms for 72 hours. Bring this log to your doctor – dose adjustments reverse side effects in 68% of cases. Not sure? We’ve got your back in when to seek professional help.
Why Food Timing Affects Sleep
Your body runs on a 24-hour clock (circadian rhythm) that tells you when to eat, sleep, and digest. Eat too late? You’re fighting biology.
1. Late meals confuse your internal clock
Eating close to bedtime disrupts glucose tolerance and melatonin production, making it harder to fall asleep. Shift workers and night owls face higher risks - studies show late-night eaters take 40% longer to fall asleep.
2. Digestion vs. rest mode
Your gut needs 3-4 hours to settle. Heavy meals (greasy, spicy, high-protein) before bed spike metabolism, raising core temperature - the opposite of what you need for sleep. Slow-digesting meals eaten late increase nighttime awakenings by 30%.
3. Blood sugar rollercoasters
High-sugar snacks before bed? They crash your blood sugar at 3 AM, jolting you awake. Low-glycemic meals 3 hours before bed improve sleep depth by 15%.

Your body loves routine - align meals with daylight, and sleep tight.
“If I just power through, my appetite will sort itself out, right?” Nope - let’s bust three stubborn myths about sleep and hunger that might be sabotaging you.
Myth 1: “Losing sleep doesn’t make you hungrier”
Truth: Skipping sleep directly hijacks hunger hormones. Even one night of poor sleep raises ghrelin (your “eat now!” hormone) by 15% and drops leptin (your “I’m full” hormone) by 18% short sleep spikes ghrelin by 15% and drops leptin by 18%. This combo makes you crave carbs and sweets - studies show sleep-deprived people eat 300+ extra calories/day sleep loss adds 300+ daily calories via cravings.
Fix: Prioritize 7-9 hours. Struggling? We’ve got 6 effective natural solutions later.
Myth 2: “Eating more fixes sleep problems”
Truth: Overeating (especially junk food) backfires. Sleep loss dulls your brain’s decision-making, making you 30% more likely to grab chips over veggies sleep-deprived brains crave 30% more junk food. Worse, late-night meals disrupt deep sleep, trapping you in a cycle of fatigue and cravings late eating reduces restorative sleep by 40%.
Fix: Eat protein-rich snacks before 8 PM (like Greek yogurt).
Myth 3: “All sleep is equal for appetite control”
Truth: Broken sleep = ravenous days. If you’re waking up 3+ times nightly, your body pumps out cortisol, spiking hunger even if you technically “slept 8 hours” interrupted sleep increases next-day hunger by 25%. Depth matters too - poor REM sleep blunts insulin sensitivity, making you store more fat weak REM sleep hikes diabetes risk 37%.
Fix: Block blue light 90 mins pre-bed (try amber glasses) and keep your room below 68°F.
Bottom line: Sleep isn’t just “downtime” - it’s your hunger thermostat. Fix your sleep first, and cravings often fade naturally. Still stuck? Check how hormones affect sleep and appetite for deeper fixes.
