The first pillar
Eating window
Eating within the same hours every day. The body learns when to expect food and regulates insulin accordingly.
The second pillar
More protein
Spreading protein across the three meals. Fullness comes sooner and lasts longer, with no willpower decisions.
The third pillar
Regular sleep
Going to bed and waking up at the same times. When sleep is steady, the hunger hormones settle down.
The fourth pillar
Movement
A ten-minute walk after lunch and dinner. It helps muscles use glucose instead of leaving it in the blood.

clinical studies behind it

You've tried everything.
Nothing lasted. Here's why.

Almost every diet attacks the symptom: calories. But your body doesn't respond to numbers — it responds to signals. If you don't fix those first, nothing holds. Here are the four most common reasons it didn't work.

🍬
The problem isn't willpower
The hunger you feel after a diet isn't weakness. It's your body reacting: when you cut calories without fixing insulin, the hunger hormones rise and the fullness hormones fall. That was a battle you couldn't win.
😴
Diets always skip sleep
One week of bad sleep raises hunger by 28% and worsens how the body uses sugar. No diet works on top of broken sleep.
🏃
Intense exercise doesn't work the way you think
Hard training feels "productive", but real weight loss needs a different kind of movement. The studies are clear: easy, regular walking rebuilds the engine that burns fat. Almost no one does it the right way.
📋
When the plan is too much, it all collapses
In diet studies, after two weeks fewer than one person in five sticks with it when the plan is complicated. The problem isn't you. It's the plan. You need a well-built sequence that adds one habit at a time.

This protocol is built
for some people, not everyone.

The Metabolic Reset works when it's followed by the right person. Read the two lists below. If you fall into one of the categories on the right, talk to your own doctor first.

It's built for you if

You're an adult in generally good health

  • You want to lose weight without restrictive diets or counting calories.
  • You've tried calorie counting, the gym, "eat less", and the results didn't last.
  • You want to sleep better, have steady energy through the day, trim your waistline.
  • You're willing to follow four habits every day for 30 days.
  • You want a method grounded in clinical studies, written by a doctor.
It's not built for you if

You fall into one of these categories

  • You have type 1 diabetes or diabetes treated with insulin.
  • You're pregnant or breastfeeding.
  • You have a thyroid condition under active treatment.
  • You have (or have had) an eating disorder.
  • You have a heart condition or a cancer under treatment.
  • You've had bariatric surgery.
  • You're under 18.
In these cases, talk to your own doctor first. The Metabolic Reset is an educational program; it doesn't replace a personalized clinical evaluation or any treatment you're on.

Four things got stuck.
The protocol unsticks them, one at a time.

In overweight but healthy adults, the metabolism doesn't break because of anything they did wrong. It's four mechanisms in the body that have jammed and reinforce each other. This protocol doesn't tell you to eat less. It helps you unstick the four mechanisms. When they return to their normal ranges, hunger eases and meals self-regulate, because the fullness hormones start working the way they should again.

Problem 01
Insulin is always high
When you eat often, and when you eat bread, pasta, refined sweets, the insulin in your blood never comes down. And while it's high, your body can't burn fat. Literally. No matter how little you eat.
Eating within a 10-hour window (Wilkinson 2020)
Problem 02
The body no longer knows how to burn fat
A "jammed" metabolism uses only sugar as fuel, never fat. That's why after meals you get energy dips, sugar cravings, and tire easily. Even a little exercise feels brutal.
Easy walking (45 minutes × 3 times a week)
Problem 03
Stress never comes down
Everyday stress and poor sleep keep cortisol (the stress hormone) high well beyond its natural morning peak. High cortisol drives belly-fat storage and makes the body insensitive to insulin — regardless of what you eat.
Sleep protocol (8 hours, same times, Tasali 2022)
Problem 04
Hunger is out of control
If you eat little protein and sleep badly, the hormones that regulate hunger and fullness go haywire. You don't overeat because you lack willpower. You overeat because your body no longer gets the right signals.
More protein: ~1.8 g per kg of body weight per day
"The protocol doesn't ask you to eat less. It fixes the reason your body won't let you eat less on its own. When you unstick the four mechanisms together, eating less happens by itself — no hunger, no weighing food, no counting anything."

Everything you need.
Nothing more.

01
The full protocol, day by day
30 days split into 4 phases. Each day has a clear goal. You don't have to invent anything or decide anything — just follow it.
02
The 4 habits, explained properly
When to eat, how much protein, how much to walk, how to sleep. For each: the minimum that works, the most common mistakes, and how to know if you're doing it right.
03
The daily blueprint
A model day to follow without thinking. What to do in the morning, when to eat, when to move, how to close the evening. All in order, every day.
04
The 30-day journal
Each day you log 5 simple things you can measure at home. No tests. No devices. The grid shows you, day by day, how you're doing.
05
The supplements that make sense
Three molecules (not brands) with real scientific evidence: which dose, when to take them, and why. You buy them wherever you like. They're not mandatory.
06
What to do from Day 31
At the end of the 30 days you'll have your own data. I explain what to keep, what to add, and how to tell if you're ready for the next step.

What happens in the body
week after week.

In clinical studies on the protocol's pillars (time-restricted eating, regular sleep, distributed protein, movement after meals), progressive changes in metabolic markers are observed. What you read below describes the documented mechanisms. Individual results vary with age, metabolic starting point, adherence to the protocol, and genetic factors.

7
Week 1
  • Deeper sleep, falling asleep faster
  • Less of an afternoon energy crash
  • Nervous snacking between meals eases
  • The body adapts to the new rhythm
14
Week 2
  • Insulin sensitivity improves
  • The waistline starts to respond
  • More stable energy through the day
  • Post-meal walks become a habit
21
Week 3
  • The body burns fat even at rest
  • Smaller post-meal glucose spike
  • More stable resting heart rate
  • Hunger is back to normal
30
Week 4
  • The four habits are automatic
  • Improved metabolic markers
  • Changed body composition
  • Food choices come naturally to you

You're probably wondering...

I've already tried everything. What's different here?
What's different is that almost every plan asks you to fix one thing: calories, or exercise, or sleep. Here we fix four together, in the right order. The studies show that changing just one while the other three stay broken doesn't work. It's the combination that makes the difference.
Does it work if I'm in peri-menopause or menopause?
Yes, but I'll tell you the truth about what to expect. After 45, the drop in estrogen really does change things: fat settles more around the belly, sleep gets worse, and the body becomes more insulin-resistant. This protocol isn't a cure for menopause — but the four habits (meal timing, protein, walking, sleep) are exactly the most-studied levers for this stage of life. Real results, a bit slower than average, and a very clear benefit especially on sleep and energy.
How long until I see changes?
The first signs are usually on sleep and energy, in the first 7-10 days. Nervous snacking eases by the second week. On the body, the metabolic mechanisms take a few weeks to re-settle. The speed depends a lot on individual factors: age, starting point, consistency, sleep, baseline activity. Don't judge weight day by day — look at the weekly average and how you feel. The most important thing isn't how much changes in 30 days, it's what you've learned to do and will keep doing afterward.
Is it just another diet?
No. You don't count calories. You don't weigh food. You don't cut out entire food groups. The protocol fixes your body's hormonal environment: when that's back in order, eating less happens by itself, because hunger normalizes. Most people, after two weeks, eat less without even trying.
Do I have to buy supplements or equipment?
No equipment. The three recommended molecules (magnesium glycinate, vitamin D3, omega-3) are optional: the protocol works without them. You can find them easily at a pharmacy or online for little money. For walking, all you need is a comfortable pair of shoes.
Is it safe? Should I check with my doctor first?
The protocol is built for generally healthy adults, with no diagnosed metabolic disease. If you have type 2 diabetes, thyroid issues, are pregnant or breastfeeding, or take medication that must be timed precisely around meals, talk to your doctor first. Inside the protocol there's a dedicated page on "what to watch" and the signals to pay attention to.
What if I've had problems with food in the past?
This protocol is not suitable for anyone who has had or has an eating disorder — such as anorexia, bulimia, or binge eating. The eating-window structure, counting protein, and measuring yourself can be triggers, and this protocol doesn't include the specialist supervision that's needed in those cases. If you have this history, I ask you to talk to a qualified specialist first. If you bought the protocol without noticing this point, we'll refund you.
Does it work with a Mediterranean diet?
Yes — the protocol doesn't prescribe specific foods. You decide what to eat; the protocol decides when and in what macro proportions. In fact a Mediterranean-style diet is an ideal base: rich in vegetables, fish, extra-virgin olive oil, whole grains, legumes. It fits in with no forcing.
If I have intolerances (gluten, lactose, FODMAP), does it work?
Yes. The protocol describes macronutrients and timing, not lists of foods. You adapt everything to your normal way of eating. Protein comes from meat, fish, eggs, legumes, dairy or plant alternatives depending on what you can eat.
Can I also do intense sport or the gym during the protocol?
Yes. Pillar 4 (movement after meals) doesn't replace sport, it sits alongside it. If you're a recreational athlete, tell your trainer you're testing an eating window: some very intense sessions might need small adjustments to meal timing.
I'm vegetarian or vegan. What about protein?
The protein pillar applies to animal and plant sources alike. For vegans the target is slightly higher, to make up for the lower digestibility of some plant proteins. The protocol gives examples of equivalent portions with legumes, tofu, tempeh, seitan, nuts.
How much time does it take each day?
The four habits fit into your normal day; they don't add hours. Choosing the eating window, distributing protein, regulating sleep, walking ten minutes after meals: zero extra minutes compared to what you already do. The time you need is for the initial read of the protocol, about an hour.
What happens after the 30 days?
The protocol is designed as a reset, not an open-ended diet. After 30 days you have two options: keep the habits if they did you good, or use what you've learned as a flexible base to adjust over the following months. There's a section dedicated to "what to do from Day 31" inside the protocol.
Can I follow it if I take medication?
It depends on the medication. Blood-pressure drugs, statins, levothyroxine: generally compatible but must be taken at the times your doctor prescribed, regardless of the eating window. Insulin, oral glucose-lowering drugs, anticoagulants, psychiatric medication: talk to your doctor before starting. The protocol changes the blood-sugar curve and this may require dose adjustments. When in doubt, a call to your doctor is always the safer choice.

Ten years of family medicine in Italy, a year on a hospital ward during Covid, the rest in the clinic. The things that really change a patient's health are sleep, meals, the daily routine, the habits. They're also the things there's almost never time to explain in a ten-minute appointment. That's what you'll find in this guide.

Most of the patients I saw didn't fail out of laziness. They failed because no one had put things in the right order. Almost every plan started with the diet and forgot about sleep, which is actually the base everything else rests on. I've seen eighty-year-old patients lose real weight by adding one walk a day. I've seen patients about to have bariatric surgery not need it anymore, just because we changed their day.

Today I consult only online, from Dubai. I work on prevention, habits, longevity. This guide is the first thing I hand to anyone who asks me where to start.
