A client asked me something I could not answer.
She was 43. She had done everything we had talked about for eight months. The food was clean, the walking was consistent, the sleep was, by her account, better than it had been in a decade. And she was still hungry at 4pm in a way that felt almost chemical. Not emotional, she said. Not boredom. Her exact words were: "It is not in my head. It is in my blood."
I have been a registered dietitian for eleven years. I do not usually know what to say when someone describes hunger that way. The textbook answers about protein timing and fibre load are not wrong, but they are not the right shape of answer either. I told her I would look into it and get back to her.
What I found, reading for a few weeks, was a line of research I had been loosely aware of but had not taken seriously. It involves GLP-1 and leptin, the two hormones that tell your body whether food was enough. And it suggests, more clearly than I expected, that the signalling between gut and brain gets noisier in the years after 35. Not broken. Noisier. The food lands, but the "I am full now" message does not always arrive on time.
That is the mechanism underneath what my client described. And it is what I wanted to test on myself before I said anything more about it to her, or to anyone else.
I am 41. I was not the control group.
Here is the part I want to be honest about. I did not start this as a neutral experiment. I had been noticing my own thing for about a year. Afternoons that felt different than they used to. A kind of dull restlessness around food that I had no language for and that my own advice did not seem to touch. It is easy, as a nutritionist, to assume that you are the exception to whatever you are writing about for other people. I was not.
So when I decided to run this test, the premise was simple. Ninety days, one product, one variable. I kept my food the same as I could. I kept my walks, my sleep, my coffee. I did not join a gym or change a single other thing. The one change was a small dropper, once a day, first thing in the morning before coffee. And a notebook. I wrote three sentences every morning and three sentences every evening. Nothing fancy. Hunger. Energy. Anything I noticed that did not fit a pattern.
"What I was actually testing was whether the afternoon feeling had a physical source. If it was real, something that addressed the mechanism should move it. If it was not, nothing would."
— Noa Berglund, RDN · April 2026The product I picked was Gelatine Sculpt. Not because it was the most advertised — it was not. It showed up in two different academic reading threads I was following, the gelatine/glycine satiety literature and a smaller body of work on African mango seed and leptin receptor sensitivity. The formula combined both. The format was liquid, which, if you care about absorption of things like berberine, matters more than most people realise. And the company had a real refund window, which I take as a proxy for whether they expect their product to survive a direct test.
Ninety mornings, roughly summarised.
I am not going to reproduce the whole notebook here. Most of it is dull, which is the point. You want a test like this to be dull. But these are the entries that mark the places where something changed, and they are, if you read them in order, the honest shape of what happened.
First dropper. Tastes a little bitter, a little green. Not unpleasant. In water, you barely notice it. No effect expected. Noting baseline: woke up hungry at 7, mild headache, usual 4pm dip expected.
Nothing dramatic yet. But I notice I ate less at dinner last night without planning to. I had half my plate and I was actually done. I remember thinking that was weird. Writing it down because it might be nothing.
The 4pm thing is quieter. I want to be careful with this because I have placebo-ed myself before. But the quality of the afternoon is different. I am not ignoring hunger. The hunger is just not showing up in the same way. I noticed around 5 that I hadn't thought about food, and normally by 5 I have thought about food several times.
Weighed this morning. Five pounds down. Without trying, really. I have not changed the food. I have changed how much of the food I want. Told my husband, who said, "Yeah, I noticed you have been eating less." Apparently this was obvious to someone paying attention from the outside. I was not paying attention from the outside.
Had a stressful week. Normally that is the moment the snacking comes back. It did not. The stress was still there, but it did not turn into food the way it usually does. I am starting to think the afternoon change is not about food at all. It is about whatever signal was mis-firing upstream of it.
Eleven pounds down. Clothes fit differently in a specific place, which is the mid-abdomen — the area where cortisol and insulin tend to show up after 40. That matches the mechanism. Energy has been steadier than usual. Sleep has been the same, maybe slightly better. I do not want to over-claim; I am reporting what is in the notebook.
Final entry of the test. Thirteen pounds down. The afternoon dip is still quieter than it was in December. I stopped needing to think about food between meals. I am, as of tonight, a person who is writing up this experiment instead of running it. I will keep taking it for another month just to see whether the trajectory continues. Then I will decide what to tell my client.
Why it might have worked on me, in plain English.
If you are going to keep taking something, you should know why. I will try to write the mechanism the way I would write it in a client note, which is the way I think about it when I am not performing expertise for anyone.
Your body has two main "I am full" signals. One is GLP-1, which the gut releases after food. The other is leptin, which fat cells release to tell the brain there is enough energy stored. Both of these travel along pathways that degrade with age and with chronic low-level inflammation. The signals are still being sent. The brain is just less sensitive to receiving them. You eat, the signal fires, the brain does not pick up the call, and you find yourself hungry an hour later when you should not be.
The ingredients in Gelatine Sculpt are aimed at this two-part problem. Hydrolyzed gelatine delivers glycine, which is one of the amino acids with the strongest evidence for supporting GLP-1 release. Berberine improves insulin sensitivity, which reduces the background inflammation that blunts leptin response. African mango seed extract has a small but real body of research on leptin receptor sensitivity. Curcumin reduces adipose tissue inflammation, which is the mechanism by which fat cells become harder to mobilise. Green tea extract supports thermogenesis at a level that is not enough to notice as jitter but is enough to matter over months. Chromium stabilises post-meal glucose, which removes the physical driver behind afternoon sweet cravings.
What you get when these work together is a return of a signal that should have been working in the first place. It is not appetite suppression in the old-fashioned stimulant sense. It is a quieter version of something that was always there. Which is what my notebook describes.
The six compounds, and what each one does.
Delivers glycine and alanine, the two amino acids with the best-studied link to satiety hormone release. For people over 40, the secondary benefit matters as much: it protects lean muscle during a period of slight calorie reduction, which protects resting metabolic rate. Most of the weight people lose and regain comes from the failure to protect this one thing.
The most studied natural compound for insulin sensitivity. Activates AMPK, the cellular energy-balance switch that gets sluggish with age. The liquid format matters here. Berberine in capsule form has notoriously low absorption, and a sublingual delivery genuinely changes the bioavailability profile.
The ingredient I was most interested in before I started. A small but consistent body of research shows improved leptin receptor response. This is the compound most likely to be doing work on the specific "hunger that does not match what you ate" pattern that my client described.
Chronic low-grade inflammation in fat cells locks them in place. You can eat in a calorie deficit for weeks and see very little change because the fat is not mobilising. Curcumin addresses that background inflammation. The effect is slow and unglamorous, which is why it does not get talked about the way it should.
Modest, sustained thermogenic effect. Not caffeine-like. Not the kind of thing you feel in the first hour. The kind of thing that adds up over months, which is the timescale this product is really designed for.
The ingredient that targets the 4pm sweet craving most directly. Stabilises the post-meal glucose curve, which takes the physiological driver out of afternoon snacking. You might still want a snack. You will not feel like you need one the way you did before.
The ritual, unexciting and on purpose.
If you want this to work, it has to be boring. The people who get results from a supplement like this are the ones who forget they are taking it because it has become part of the first ten minutes of their day. Here is the exact rhythm I settled into after about week two.
One full dropper in a small glass of water, first thing after I get up. Before coffee. The only non-negotiable is that it happens before you introduce any other variable to your morning.
Most of what I noticed first arrived between days 14 and 24. Not day 3. Not day 7. If you are the kind of person who gives up on things at day 10, this is not going to be for you, and I would rather you know that now.
The first thing that changes is how food feels. That is the signal the formula is doing its job. Weight follows. If you are only watching the scale, you will miss the thing that tells you it is working.
Other women who ran a version of this test.
After I wrote the first draft of this piece, I sent it to three women I have stayed in touch with from my practice who had been testing the formula on their own, independently, before I started. They agreed to share what their last few months looked like. I have kept their words close to what they said to me.
"I turned 46 in October and had been quietly losing the plot about my body for about three years. I was sceptical. I am still sceptical of most things that come in a dropper. But the afternoon is quiet now and I weigh what I weighed at 40. I do not know how else to describe it."
"I am a pharmacist. I read the label before I read the marketing. The formula is honest. The liquid format for berberine absorption is a real advantage that most people will not notice. I have been using it since December and the change in my appetite is the most surprising thing about my year."
"The thing I keep telling friends is that I did not start eating less on purpose. I started eating less because food stopped being the thing I thought about in the afternoon. The weight came off after. Not the other way around. That is the detail that matters."
These accounts reflect individual experiences. They are not guarantees of identical outcomes. Results will differ based on biology, routine, and baseline health.
