Diet-to-blood-marker bridges: which foods move which numbers
A blood test tells you where you are, not what to change. Misi builds a bridge from each dietary lever to the marker it drives — then tracks whether your numbers are actually moving the right way.
On a GLP-1? The muscle you must not lose
Semaglutide and tirzepatide strip weight fast — but a large share of it can be muscle, not just fat. Here is the protein-and-training protocol that protects lean mass, and how Misi tracks it.
Zone 2 vs intervals — the two speeds that build an aerobic engine
Zone 2 and high-intensity intervals are not rivals — they build different parts of the same engine. Here is what each does, how much you need, and how Misi targets both.
Creatine is not just for muscle — the brain, ageing and the women’s case
Creatine is the most-researched supplement in sport — and the evidence now reaches well beyond the gym, into cognition, healthy ageing and women’s health. Here is what holds up, and one lab quirk Misi accounts for.
The cholesterol number your standard panel hides — ApoB explained
Your LDL cholesterol can look fine while your real cardiovascular risk is high. The number that resolves the contradiction is ApoB — and most standard panels do not show it.
Menopause, muscle and bone — defending both with protein and lifting
The menopause transition accelerates the loss of muscle and bone — but the two most effective countermeasures are firmly within your control. Here is the protein-and-training case, and how Misi tracks it.
The 30-plants question — fibre, diversity and what your week is missing
Most people eat barely half the fibre they need, and far fewer different plants than their gut would like. Here is the evidence behind the targets — and how Misi shows the gap.
Ultra-processed food — why a curated database sidesteps the problem
The strongest evidence against ultra-processed food is not a scare story — it is a metabolic-ward experiment. Here is what it showed, the honest nuance, and why a whole-food meal database is a structural answer.
Glucose spikes and the CGM hype — what your fasting markers really tell you
Continuous glucose monitors have gone mainstream for people without diabetes. Here is what the spikes do and do not mean — and the validated markers that tell you more.
Strength is a vital sign — why your 1RM tracks your lifespan
Muscular strength is one of the most powerful predictors of how long you will live — rivalling blood pressure and smoking. Here is the evidence, and why Misi treats your strength as a longevity metric.
Sauna and cold — the evidence, and what your readiness score shows
Sauna has surprisingly strong longevity data; cold plunges are buzzier but more mixed — and timing one wrong can cost you gains. Here is what holds up, and how Misi tracks the effect on recovery.
How much protein actually builds muscle — and why leucine pulls the trigger
Building muscle comes down to two numbers most people never track: how much total protein you eat per kilogram of bodyweight, and how much leucine lands in each meal. Misi plots both against the evidence.
Protein, muscle and a longer life — why skeletal muscle is your retirement fund
Muscle is not just for the gym. It is metabolic reserve, fall protection and one of the strongest predictors of how well you age. And protecting it means raising your protein target as you get older, not lowering it.
Protein quality, not just quantity — why leucine decides if a meal counts
Two meals can have the same protein on the label and do completely different things to your muscle. The difference is amino-acid quality — and above all, leucine. Here is how to tell, and how Misi tracks it.
The daily macro problem — hitting your numbers without a spreadsheet
Real food does not arrive in round numbers. Most days you finish 20g of protein short or a little over on carbs — and fixing it by hand is fiddly. Misi turns it into a single dial.
How much training actually builds muscle — counting sets per muscle
Hypertrophy is dose-dependent, and the dose is weekly sets per muscle — not how hard a session felt. Misi counts it for you, splits direct and indirect work, and plots each muscle against its evidence-based target band.
PhenoAge explained — what your bloods say about your real age
PhenoAge turns nine standard blood markers into a single number: how old your body is actually functioning. Here is how it works and how to lower it.
VO2max is the strongest mortality predictor we have. Here is why.
A landmark 2018 Cleveland Clinic study found the mortality gap between low-fit and elite-fit is larger than between smokers and non-smokers. VO2max is the metric behind it.
The Sunday prep blueprint we generate for our users
Meal-plan abandonment usually happens at the cooking step, not the planning step. Here is the batch-prep system Misi generates automatically — with food-safety rules built in.
The honest 2026 list of MyFitnessPal alternatives
MyFitnessPal is a great food diary and a poor coach. If you have outgrown logging-only, here are the real alternatives compared honestly.
Why we plan from a curated meal database — not AI-invented recipes
Most "AI meal planners" hallucinate recipes with macros that do not add up. Misi does the opposite: it selects from a lab-checked database of real meals and portion-scales them to your exact targets.
Auto-regulation: how a 10-second tap test rewrites today’s workout
Training the same volume on three hours of sleep as on nine is how people get hurt and stall. A quick tap test reads your central nervous system each morning, and Misi scales the session before you start.
Your daily readiness score: five signals, one number, before you lift
Sleep, a CNS tap test, how you feel, your RPE trend and recent training load each tell you something about recovery. Misi fuses them into one readiness score so you know how hard to go today.
Physique Lab: why bodyweight is a terrible progress metric
The scale conflates muscle, fat, water and gut contents into one misleading number. Misi’s Physique Lab tracks what actually changed using body scans, progress photos and posture analysis.
The whole-person health dossier no other app produces
Your bloodwork lives in one app, your training in another, your photos in your camera roll. Misi’s Executive Clinical Report fuses all of it into one clinician-ready PDF.
Per-muscle weekly volume: the number that actually drives growth
Hypertrophy research keeps returning to one variable: weekly sets per muscle. Misi tracks it per muscle and tells you when you are under, in, or over the productive range.
Beyond PhenoAge: the longevity panel Misi reads from your bloods
One blood panel contains far more than a cholesterol number. Misi extracts cardiovascular, kidney, metabolic and inflammatory risk signals and forecasts where they are heading.
The shopping list that merges, strips and scales your whole week
A meal plan is useless if the grocery shop is a mess. Misi’s Provision Vault turns seven days of meals into one clean, de-duplicated, correctly-scaled list.
An AI coach is only as good as what it knows about you
Generic chatbots give generic advice because they know nothing about you. The Misi AI Coach answers with your bloods, your lifts and your last week of meals in context.
Training VO₂max on purpose: the HIIT and cardio engines
VO₂max is the strongest fitness-based mortality predictor we have — and it is trainable. Misi builds the interval and steady-state work that actually moves it.
Low-FODMAP without the misery: planning meals that calm your gut
A low-FODMAP diet is one of the most effective tools for IBS — and one of the hardest to do alone. Here is how Misi takes the guesswork out of planning gut-friendly meals.
Beyond calories: how Misi tracks your macros and micronutrients
Hitting your protein target says nothing about whether you got enough potassium, magnesium or vitamin D. Misi tracks the full picture — macros and micros — and shows you the gaps.
"Is my heart heading for trouble?" Reading your 10-year ASCVD risk
Heart disease rarely announces itself until it is advanced. Your 10-year ASCVD risk score turns routine bloods into an early-warning number — and Misi calculates and tracks it for you.
"Am I becoming insulin resistant?" HOMA-IR and TyG, explained
Insulin resistance builds for years before fasting glucose ever looks abnormal. Two simple indices — HOMA-IR and TyG — catch it early, and Misi computes both from your bloods.
"Which of my habits is actually working?" Mapping habits to bloods
You changed five things at once and your numbers improved — but which change did the work? Misi correlates the habits you log with the biomarkers that move.
"Am I aging faster than the calendar?" Your Fitness Age Trajectory
Two people the same age can have bodies a decade apart in function. Misi turns your fitness data into a Fitness Age — and, more importantly, shows which direction it is moving.
"How many good years do I have left?" The composite longevity score
No single marker captures healthspan. Misi blends your biomarkers, fitness and trends into one composite longevity score — and a trajectory horizon you can actually influence.
"What if my bloods flag something serious?" Critical biomarker alerts
A genuinely alarming lab value should never get lost in a PDF. Misi scans your uploaded bloods and surfaces critical readings so you can act — and talk to a doctor — fast.
"App or human coach?" Why Bio-Elite means you do not have to choose
Software scales; humans bring judgement and accountability. Misi’s coach portal lets a real coach work inside the same app that builds your plans — so you get both.
"Why am I always flat in the gym?" Iron and hormones may be the answer
Persistent fatigue and stalled progress are often blamed on programming when the real cause is in your bloods. Misi tracks iron and hormonal panels that training apps ignore.
The daily habits that actually move the needle on longevity
The science on lifespan keeps pointing back to a short list of unglamorous daily habits. Here is what the evidence supports — and how Misi helps you make them stick.
Hydration done properly: training days, rest days, fasting — and sauna
Most people treat hydration as one flat number. Your body does not. Here is how fluid needs shift across training, rest, fasting and heat exposure — and how Misi calculates each.
Training with your cycle, not against it
Most training plans were built on male physiology and run the same all month. For half the population, hormones move in a predictable rhythm — and your programming can move with them.
Why you stopped getting stronger — and how to spot it early
A plateau rarely announces itself. By the time you feel stuck, you have usually been stuck for weeks. Here is how to catch it in the data before it costs you a month.
When to rack the bar: autoregulation without a sensor
Grinding extra reps when bar speed has collapsed builds fatigue, not strength. You do not need a £300 velocity device to know when to stop — you need the right cues.
Meals that fit your bloodwork, not just your macros
Two meals can hit identical macros and have opposite effects on your lipids, inflammation and glucose. Misi scores meals against your actual blood results.
Eating out without derailing your goals
Restaurants are where good intentions quietly fall apart. You do not need to skip the meal out — you need a plan for the menu in front of you.
Is your cardio actually building fitness — or just burning time?
Most recreational cardio lives in a grey middle zone: too hard to build an aerobic base, too easy to drive real adaptation. Your heart-rate distribution tells the truth.
Training around a niggle without making it worse
A sore shoulder does not have to cost you a month. The mistake is usually all-or-nothing: train through it and aggravate it, or stop entirely and lose momentum.
Why meal plans break — and how Misi bends instead
Every meal plan looks perfect on paper. Then real life happens: a last-minute dinner out, a rushed work morning, or simply not fancying the meal you scheduled. That is where most plans quietly die.
What goes into a genuinely bespoke training plan
A real training plan is not a template with your name on it. Here is what Misi actually weighs up — from your goal and equipment to your injuries and bloods — to build a programme around you.
Your supplement stack: forms, pairings and why less is more
The supplement aisle sells confusion. Misi builds a tight, evidence-based stack around your goals, your wellbeing and — where available — your blood work, with the forms and pairings that actually matter.
The data behind your bespoke nutrition protocol
Your macro targets are not plucked from a calculator widget. Here is the chain of data — from energy expenditure to your blood work — that Misi uses to build a nutrition protocol that fits you.
New bloods in, whole new plan out
Most apps let you log a blood test and then do nothing with it. In Misi, new biomarker results can regenerate your entire plan — training, nutrition and supplements — around what your body just told you.
