Snacking is eating outside of meals, triggered not by physiological hunger but by an urge to eat that is emotional, hormonal or simply automatic. It mostly involves fatty and sugary foods, and its mechanism is not a matter of willpower: it rests on identifiable signals — unstable blood sugar, too little protein at breakfast, raised cortisol, an established ritual. In this article, Arnaud, pharmacist and pharmacy owner, explains why these urges appear, how to tell hunger apart from an urge, and sets out the 12 most useful natural anti-snacking tips to space out and then eliminate eating between meals.
Why do we snack when we are not really hungry?
Four main mechanisms combine in most people affected.
- Reactive hypoglycaemia: a meal rich in rapidly digested carbohydrates causes a blood sugar spike, followed by a large release of insulin, then a drop that reawakens the urge to eat two to three hours later.
- A meal that does not satisfy: protein and fibre are the two components that keep you feeling full the longest. A sugary breakfast without protein mechanically sets up the 10 or 11 a.m. slump.
- Stress and cortisol: cortisol, released during prolonged tension, increases the appeal of fatty and sugary foods. This is the mechanism behind so-called comfort snacking.
- Automatic behaviour: the gesture becomes tied to a context (opening the cupboard on arriving home, the screen in the evening). The trigger becomes the context itself, regardless of hunger.
In the pharmacy, we notice that most people who come in looking for an appetite suppressant do not in fact have a hunger problem, but a breakfast too low in protein and an evening meal eaten too late. Correcting those two points is very often enough for the request for a supplement to disappear.
How can you tell real hunger from the urge to snack?
This sorting step is the highest-value habit in the whole article, because it stops you treating with food what actually belongs to emotion or habit. Three questions are enough, at the moment the urge appears:
- How long has it been there? An urge that appeared in a few seconds is not hunger.
- Would any food do? If only chocolate will do, this is not hunger.
- What happened just before? A tense meeting, a difficult call, boredom: the trigger is almost always identifiable.
A non-food urge generally fades within ten to fifteen minutes if you fill the gap differently: drink a glass of water or an unsweetened hot drink, step outside, call someone. That interval is what you are trying to win, not a battle of willpower.
What part does the glycaemic index play in cravings?
The reference classification distinguishes three levels: low GI up to 55, medium GI from 56 to 69, high GI from 70 upwards. Two factors shift this value considerably: cooking (quick-cook rice sits around 85, basmati rice around 50) and the presence of fibre, protein or fat in the same meal, which slows carbohydrate absorption.
| Food | Indicative GI | Level | Practical consequence |
|---|---|---|---|
| Chips (French fries) | 95 | High | Marked blood sugar spike, rapid slump |
| Quick-cook rice | 85 | High | Choose basmati or cook al dente |
| White bread | 70 | High | Frequent mid-morning craving |
| Ripe banana | 60 | Medium | Pair with nuts or a dairy food |
| Multigrain bread | 45 | Low | Keeps you going longer than white bread |
| Green beans | 30 | Low | Volume and fibre, best at the start of a meal |
| Dark chocolate 70 % | 25 | Low | Two squares beat a sugary biscuit |
| Oat bran | 15 | Low | Rich in beta-glucans, useful at breakfast |

Which eating habits really keep you full until the next meal?
These are the first six tips, and the most decisive. They act on the cause rather than the symptom.
- 1. A breakfast with protein. After eight to ten hours of overnight fasting, a purely sugary breakfast sets up the mid-morning slump. Egg, fromage blanc, lean ham, nuts or cheese change the shape of the morning completely. Breakfast should cover roughly 20 to 25 % of the day’s energy intake.
- 2. Meals at regular times. A body used to stable timings anticipates its digestive and hormonal secretions better. Shifted or skipped meals are one of the leading causes of late-afternoon snacking.
- 3. A planned snack, not an improvised one. Cutting out the afternoon snack is not a good strategy: it simply moves the problem to pre-dinner drinks and the evening meal. A snack chosen in advance — a piece of fruit and a handful of almonds, a plain yoghurt — is a meal, not snacking.
- 4. Twenty minutes at the table, minimum. Satiety signals take about twenty minutes to reach the brain. Eating seated, without a screen, putting your fork down between mouthfuls, lets those signals arrive before the meal ends.
- 5. Fibre at the start of the meal. Starting with raw or cooked vegetables takes up stomach volume and slows the absorption of the carbohydrates that follow. Lamb’s lettuce, apple, aubergine and pulses are particularly useful here.
- 6. Hydration spread out. EFSA sets reference total water intakes of 2 litres a day for women and 2.5 litres for men, food and drink combined, which corresponds to roughly 1.5 litres of fluids. Sipping throughout the day rather than drinking a litre at once is more effective and better tolerated. A green tea, a herbal tea or an unsweetened infusion is a useful replacement for the 5 p.m. snacking ritual — the gesture matters as much as the drink.
How do you break the stress and comfort-snacking loop?
Cortisol, released in response to prolonged tension, increases the appeal of fat and sugar. No supplement replaces reducing the source of stress, but two levers help.
- 7. Name the trigger and plan the substitute. Noting the time, the context and the emotion attached to each episode for one week makes the pattern visible. Each identified trigger is then paired with a ten-minute action that does not involve food.
- 8. Cover your magnesium and vitamin B6 needs. Under Regulation (EU) No 432/2012, magnesium contributes to the normal functioning of the nervous system and to the reduction of tiredness, and vitamin B6 contributes to normal energy-yielding metabolism. They are found in pulses, nuts, wholegrain cereals and dark chocolate; supplementation should be discussed with your pharmacist. Our vitamins and minerals range offers the forms best tolerated by the digestive system.
Where the link between psychological tension and eating becomes central, our article on the role of stress in eating disorders explores the subject further.
Which fibres and plants can genuinely claim an effect?
This is where the market talks the most and the regulation is strictest, so it is worth being clear about what is demonstrated and what is not. Mucilaginous fibres absorb water and increase the volume of the stomach contents; they are therefore taken 15 to 20 minutes before the meal, with a large glass of water — without water they serve no purpose.
- 9. Glucomannan (konjac). Extracted from the Amorphophallus konjac tuber, it absorbs a very large amount of water. It is the only active in this field with a claim authorised by Regulation (EU) No 432/2012: glucomannan contributes to weight loss in the context of an energy-restricted diet, under precise conditions of use of 3 g a day in three doses of 1 g, with 1 to 2 glasses of water, before meals. It has, on the other hand, no demonstrated effect on cravings for sugar or fat. Our pharmacists supply it notably as konjac capsules.
- 10. Beta-glucans from oat bran. Two authorised claims apply: consuming oat beta-glucans as part of a meal contributes to reducing the rise in blood glucose after that meal, and an intake of 3 g a day contributes to the maintenance of normal blood cholesterol levels. With a GI of 15, oat bran is the most coherent ingredient for an anti-craving breakfast. Usual recommended intake does not exceed 3 tablespoons a day.
- 11. Guar gum. Rich in galactomannans, it forms a gel on contact with water and slows gastric emptying. Its authorised claim concerns cholesterol — guar gum contributes to the maintenance of normal blood cholesterol levels, at 10 g a day — and not appetite. It is valued for its regulating effect on transit.
- 12. The other mucilages: carob, sterculia, apple pectin, agar-agar. These are soluble fibres that swell on contact with water and increase stomach volume, without being digested or absorbed. No satiety or weight-loss claim is authorised for them to date: they are used as mechanical support and as an aid to transit, not as a treatment. apple pectin is one simple form to use.
| Active | Mechanism | Authorised claim (EU 432/2012) | Precautions |
|---|---|---|---|
| Glucomannan (konjac) | Water absorption, stomach volume effect | Yes: weight loss in the context of an energy-restricted diet, 3 g/day in 3 doses | Always with 1 to 2 glasses of water. Avoid in case of swallowing difficulties or digestive stricture |
| Oat beta-glucans | Slower carbohydrate absorption | Yes: post-meal blood glucose and normal blood cholesterol | Introduce gradually, bloating possible |
| Guar gum | Viscous gel, slower gastric emptying | Yes, on blood cholesterol only (10 g/day) | Leave 2 hours between this and medicines |
| Carob, sterculia, pectin, agar-agar | Soluble fibres, stomach volume | No | Adequate fluid intake essential |
| Fucus vesiculosus | Brown seaweed rich in mucilage | No | Very rich in iodine: contraindicated in thyroid disorders or iodine allergy. Pharmacist advice essential |
Two important warnings. First, doubling the dose does not increase the effect and exposes you to digestive upset (bloating, diarrhoea, stomach pain) as well as reduced absorption of any medicine taken at the same time: always leave two hours between them. Second, fucus, often found in so-called slimming formulas, is a brown seaweed very rich in iodine; it must not be used without pharmacist advice if you have a thyroid disorder, as our article on the thyroid and the endocrine glands sets out.
Finally, plants that act on mood and sugar cravings — griffonia, sage — follow a different logic from fibres: they are covered in our article on slimming down with medicinal plants.
When should you talk to a doctor or pharmacist?
Occasional snacking is part of normal life: a slice of cake or a square of chocolate needs no correction. What justifies professional advice is repetition and loss of control.
See your doctor in the following situations:
- Eating episodes experienced as uncontrollable, followed by guilt, shame or compensatory behaviours — these are signs that should raise the possibility of an eating disorder, and effective treatment exists.
- Unusual intense hunger, excessive thirst, frequent urination, marked fatigue: a blood glucose assessment is warranted.
- Rapid, unexplained weight gain or loss, or a known thyroid disorder.
- Snacking that started with a new medicine (corticosteroids, some psychotropic treatments): never stop a treatment on your own, speak to your doctor.
- Pregnancy, breastfeeding, children, adolescents, older adults: no appetite-suppressant supplement should be taken without medical advice in these situations.
Your pharmacist is the first person to check whether a fibre or a plant is compatible with your current treatments, to adjust the timing of doses and to spot what needs medical attention. For structured support, our article on the benefit of weight management in a pharmacy explains how follow-up works.
Our pharmacists’ advice on where to start
An effective natural anti-snacking approach follows a clear order. This is the one we give over the counter:
- Weeks 1 and 2: protein breakfast, stable timings, planned snack. Nothing else.
- Week 3: keep the emotional trigger diary and correct magnesium intake if needed.
- From week 4: if the urges persist, try a mucilaginous fibre before the two most exposed meals, with a large glass of water.
For that last step, browse the full selection put together by our pharmacists in our appetite suppressants and satiety fibres department, along with our dietetic snacks to structure the afternoon break. The whole range is available in our weight-management food supplements category, and delivery is free from 59 € of purchases.

Frequently asked questions about snacking
What is the best natural appetite suppressant?
There is no miracle natural appetite suppressant. The only active with an authorised claim in the European Union is glucomannan from konjac, at 3 g a day with a large glass of water, as part of an energy-restricted diet. A breakfast rich in protein is nevertheless more effective than any supplement at reducing how often cravings occur.
Why do I mainly want to snack in the evening?
Evening snacking combines three factors: a lunch that was too light or too sugary, the drop in alertness at the end of the day which lifts inhibition mechanisms, and the soothing role attached to food after a tense day. Increasing protein and fibre at lunch, then planning a snack around 5 p.m., changes the picture within a few days.
Does green tea make you lose weight?
No, no weight-loss claim is authorised for green tea in the European Union. It remains useful against snacking for another reason: an unsweetened hot drink replaces the gesture and fills the ten to fifteen minutes during which the urge fades.
Should you cut out the afternoon snack to stop snacking?
No, that is usually counterproductive. Removing the afternoon snack most often leads to larger pre-dinner drinks and a larger evening meal. A snack chosen and planned — a piece of fruit with a handful of nuts, or a plain yoghurt — is a structured meal, not snacking.
When should you see a doctor or pharmacist about snacking?
See someone if episodes become uncontrollable, if they are followed by significant guilt or compensatory behaviours, or if they come with unusual hunger and thirst, marked fatigue or an unexplained change in weight. Also ask your pharmacist’s advice before taking any fibre or plant if you are on a treatment, pregnant or breastfeeding.
