THE VANISHING HUNGER ▶ 0:00

THE VANISHING HUNGER — On a GLP-1, hunger goes quiet

Something odd happens on a GLP-1 medicine. The nine o'clock rumble, the fridge magnetism at midnight — it just stops. For some people that's a relief. For others it's a problem nobody warned them about: how do you eat well when you don't want to eat at all? This film isn't about the jab. It's about what goes on the fork afterwards — protein first, small plates, and the foods people say actually sit.

ACT ONE · THE SWITCH ▶ 0:34

ACT ONE · THE SWITCH — What these medicines actually do

These medicines belong to a class called GLP-1 receptor agonists — they copy a gut hormone your body already makes after eating. That hormone does two things: it tells your pancreas to manage blood sugar, and it tells your brain, quite firmly, that you've had enough. It also slows how fast your stomach empties. The result is real, physical fullness, arriving on much less food than before. That's the mechanism — everything else in this film follows from it.

THE EARLY FULL SIGNAL ▶ 1:00

THE EARLY FULL SIGNAL — Full after four bites, not forty

Because the stomach empties slowly, fullness now arrives early — sometimes four or five bites in. A plate that used to take twenty minutes might feel finished at five. This isn't willpower. It's mechanical. The stretch receptors in your stomach fire sooner, and the brain gets the memo faster. Understanding that it's physiology, not virtue, matters — because the next challenge is making those few bites actually count.

THE HIDDEN RISK ▶ 1:24

THE HIDDEN RISK — Losing weight, but from where?

Here's the part that gets less airtime. When you eat less overall, you don't just lose fat — you can lose muscle too, if the diet quality isn't there. Research on rapid weight loss consistently shows lean muscle can make up a meaningful share of it. Muscle is what keeps your metabolism ticking over and your body strong as you age. So the goal on a GLP-1 isn't just eating less. It's making the little you do eat count, protein-wise, every time.

MYTH VERSUS EVIDENCE ▶ 1:50

MYTH VERSUS EVIDENCE — 'Whatever fits' isn't a strategy

A common myth: since appetite is so small, it doesn't matter what fills it. The evidence says otherwise. If your only room each day goes to crackers and toast because they're easy, you can end up under-fed on protein even while losing weight steadily. Dietitians who work with GLP-1 patients see this pattern often — small appetite, but the wrong foods filling it first. The fix isn't more food. It's smarter order.

ACT TWO: PROTEIN FIRST ▶ 2:13

ACT TWO: PROTEIN FIRST — Why protein goes on the fork first

Protein does three jobs at once here. It preserves muscle while you lose fat. It keeps you fuller for longer, gram for gram, than carbs or fat. And because your total appetite is small, whatever you eat first tends to be whatever you actually finish. So the practical rule dietitians suggest: protein goes on the fork first, every meal, before the vegetables, before the carbs — while there's still appetite left to spend on it.

THE PLATE, IN ORDER ▶ 2:37

THE PLATE, IN ORDER — A worked example: one small meal

Picture a typical small plate: two eggs, a few spoons of vegetables, a small potato. Eaten protein-first, it might look like this — the eggs disappear first, fully, while appetite is strongest. Then vegetables, for fibre and volume. The potato, if there's room, comes last, and it's fine if it doesn't get finished. Nothing wrong with a plate that goes home half-eaten, as long as the protein went in first.

THE PALM RULE ▶ 2:59

THE PALM RULE — How much protein actually fits

A simple visual: a portion roughly the size and thickness of your palm is a reasonable protein target per meal on a reduced appetite. That's around twenty to thirty grams for many people — not a huge plate, but enough to matter. It won't always be finished, and that's fine. The aim across a full day is steady small protein hits, not one heroic meal.

SMALL PLATE, BIG VALUE ▶ 3:19

SMALL PLATE, BIG VALUE — When there's little room, make it count

With appetite this limited, nutrient density becomes the whole game. A small bowl of Greek yoghurt with nuts carries far more protein, calcium and healthy fat than the same-sized bowl of cereal. The question worth asking before each small meal isn't 'what do I fancy' — it's 'what's doing the most work in this tiny amount of room.' That single question reshapes most food choices on a GLP-1.

ACT THREE · WHAT SITS ▶ 3:42

ACT THREE · WHAT SITS — The foods people say sit best

People on GLP-1 medicines commonly report that soft, plain, protein-rich foods sit most comfortably — Greek yoghurt, scrambled eggs, poached fish, cottage cheese, a smooth soup with beans blended through it. The common thread: soft texture, moderate fat, not too rich, not too fast. None of this is a rule written in stone — everybody's tolerance differs — but these are the foods that turn up again and again in people's own accounts.

WHAT COMMONLY DOESN'T ▶ 4:09

WHAT COMMONLY DOESN'T — The foods people say fight back

On the other side, heavy, greasy, or very rich foods are commonly reported as harder going — fried food, thick creamy sauces, large amounts of red meat in one sitting. It's thought to be linked to that slower stomach emptying: fat sits there longer, and on top of an already-full stomach, it can tip into nausea. Again, this varies person to person, but it's a pattern worth knowing before you order.

TEXTURE OVER TASTE ▶ 4:32

TEXTURE OVER TASTE — Why soft and cool often wins

Texture often matters more than flavour here. Cool or room-temperature food, soft rather than chewy, tends to be reported as easier than hot, dense, or fibrous meals eaten quickly. Eating slowly matters too — the fullness signal has a lag, so a rushed plate can feel fine at minute two and uncomfortable at minute six. Slowing down isn't just pleasant. On a GLP-1, it's practical.

THE HYDRATION GAP ▶ 4:56

THE HYDRATION GAP — Why drinking enough gets forgotten

Appetite for food drops — but so, often, does appetite for drink. And with less food overall, you're also getting less fluid from meals than before. Dehydration is commonly reported alongside these medicines, and it can make nausea feel worse, not better. Sipping water steadily through the day, rather than waiting to feel thirsty, is one of the simplest things people say makes the biggest difference.

SIPPING, NOT GULPING ▶ 5:19

SIPPING, NOT GULPING — A worked example for a hard day

On days appetite disappears completely, a warm mug of stock or bouillon can do double duty — fluid and a little sodium, sipped slowly rather than a large glass necked in one go. Small and frequent beats big and occasional, for drink just as much as food. It's a low-effort habit that supports the harder ones around it.

A DAY, WORKED THROUGH ▶ 5:38

A DAY, WORKED THROUGH — What tiny nourishing actually looks like

A realistic day on reduced appetite might look like this: morning, a small pot of yoghurt with a spoon of nuts. Midday, two eggs and a few bites of avocado. Evening, a small portion of fish with soft vegetables. None of it looks like a normal meal by old standards. Added up, though, it can land somewhere close to sixty or seventy grams of protein — enough to genuinely protect muscle, spread across a day appetite actually allows.

WHEN TO CHECK IN ▶ 6:02

WHEN TO CHECK IN — The line between normal and worth flagging

Reduced appetite is expected. Being unable to keep fluids down, persistent vomiting, or not eating almost anything for days is not something to just wait out. Commonly reported side effects like nausea usually settle, but if eating or drinking becomes genuinely impossible, that's a conversation for your GP or pharmacist, not something to self-manage. This film covers food, not medical decisions — those sit with the people who know your case.

FILLING THE GAPS ▶ 6:29

FILLING THE GAPS — Does a multivitamin make sense here?

With such small food volumes, some people wonder about a general multivitamin as insurance against gaps — iron, B12, vitamin D are the ones most commonly discussed. It's not a replacement for real food, and it's not something this film can advise on personally. But it's a sensible question to raise with a GP or pharmacist, alongside how the eating itself is going.

ONE HABIT THAT STICKS ▶ 6:50

ONE HABIT THAT STICKS — If you remember only one thing

If everything else in this film slips your mind, keep this: protein first, on every small plate, every time. Not because more is always better — appetite here has its own rules — but because when there's only room for a little, that little should work as hard as possible for you. Small plate. Big value. That's the whole method.
