Question-intent science hub
Peer-reviewed answers for the fitness questions people actually ask.
Each page starts with the answer, then shows the practical coaching move, claim guardrail, FAQ schema, and PubMed-backed source trail. This is the bridge between Geebs Instagram science posts and the evergreen search questions those posts create.
Traffic role
The library earns trust. The question pages earn discovery.
Broad study pages prove the source trail. These question pages are built for the exact prompts people search, ask in comments, and send to AI assistants: caffeine before bed, protein for recomp, creatine after 30, cravings, fasting, cardio, and healthy aging.
Current index
13 answer-first science pages.
Every card links to a canonical QAPage with FAQPage and source-list schema.
Sleep and cravings answer
Does poor sleep cause cravings?
Poor sleep does not guarantee cravings, but sleep restriction can make appetite, snack intake, training quality, and decisions harder to control. The useful coaching move is to audit the sleep pattern before treating late-night cravings like a character flaw.
Protein and recomp answer
How much protein do you need for body recomposition?
Protein is one of the most reliable supports for body recomposition, but it is not magic by itself. Training creates the adaptation signal; protein helps support satiety, recovery, and lean-mass retention while calories are managed.
Cardio and lifting answer
Does cardio hurt muscle growth?
Cardio does not automatically hurt muscle growth. The issue is dose, timing, modality, recovery, and whether cardio competes with the lifting stimulus. A good plan uses cardio for health and capacity while keeping strength training the priority.
Strength and aging answer
Does strength training help you age better?
Strength training is one of the most practical healthy-aging levers because it supports muscle, function, and physical capacity. The responsible claim is not that lifting reverses aging; it is that keeping strength and muscle makes aging more resilient.
Cravings and appetite answer
Do cravings mean you are deficient?
Cravings do not automatically mean you are deficient. That explanation is usually too simple. Sleep, protein, meal timing, stress, food cues, and the home food environment can all change the odds of overeating.
Caffeine and sleep answer
Does caffeine before bed hurt sleep?
Caffeine before bed can hurt sleep for enough people that it deserves a real audit, especially if late training, pre-workout, or afternoon coffee keeps showing up before bad sleep. The coaching move is not panic; it is testing timing, dose, and consistency.
Fasting and fat-loss answer
Is intermittent fasting better than calorie restriction?
Intermittent fasting can work, but the responsible claim is that it works when the eating window makes the calorie deficit easier to sustain. It is not automatically better than ordinary calorie restriction, especially if the shorter window makes protein harder to hit.
Creatine and aging answer
Should men over 30 take creatine?
Creatine is one of the more defensible supplements for trained adults, but it is still support, not the plan. The useful hierarchy is resistance training, protein, sleep, then creatine if it fits health context and consistency.
Food environment answer
Are ultra-processed foods bad for fat loss?
Ultra-processed foods are not morally bad, but they can make fat loss harder when they increase passive calorie intake, cravings, and repeated food-cue decisions. The coaching move is default design, not fear-mongering.
HIIT and steady cardio answer
Is HIIT better than steady cardio for fat loss?
HIIT is not automatically better than steady cardio for fat loss. If calorie burn is similar, body-composition changes can be similar too. The better choice is the one you recover from, repeat, and can place without hurting lifting performance.
Phone and sleep answer
Does using your phone in bed hurt sleep?
Phone use in bed is not neutral for many people. It can keep the brain engaged, expose you to light at the wrong time, and push sleep later. The useful coaching move is not a perfect evening routine; it is getting the phone out of the bed environment first.
Protein and hunger answer
Does protein help you stay full?
Protein can help many people feel fuller and make a fat-loss plan easier to repeat, but it is not a hunger off-switch. Its best coaching use is as a meal-structure anchor that protects lean mass and reduces the odds of random grazing.
Lifting and longevity answer
Is lifting enough for longevity?
Lifting belongs in the longevity conversation, but it should not be the only adult-health lever. Strength training supports muscle and function; cardio, steps, and movement variety support capacity and health in different ways.
