In the era of mindful eating, more and more people are looking for healthy snacks to maintain energy and take care of their health. However, not all products labeled as “healthy” are as harmless as they seem. Some snacks can trick your brain, making you eat more than you really need or triggering cravings without you noticing. In this article, we analyze why this happens and give you smart alternatives for snacking without guilt.
Why do some healthy snacks make us eat more?
The illusion of healthiness
When a food carries labels like “low fat,” “no added sugar,” or “100% natural,” our brain tends to perceive it as less caloric or completely harmless. This phenomenon is known as the halo effect.
For example, a handful of whole-grain cookies may seem much less caloric than a regular cookie, but their energy density is still high. This can make us eat more than we actually need, exceeding the calories that a “less healthy” snack would provide in a smaller portion.
The role of texture and flavor
The brain responds strongly to crunchy textures and sweet or salty flavors. Many “healthy” snacks are designed to provide these sensations without the usual fat or sugar.
Although they contain ingredients that seem nutritious, the combination of taste, aroma, and texture activates reward centers in the brain, causing cravings and overconsumption.
The “healthy” snacks that deceive the most
Nuts are highly nutritious, rich in healthy fats and protein, but when roasted with sugar or honey, their caloric density skyrockets. A small handful can have more calories than a conventional chocolate bar, and the sweet flavor can make the brain feel like you need to keep eating.
Most granola bars marketed as healthy contain added sugars, corn syrups, and refined oils. The advertising emphasizes oats and nuts, but sugar remains the star, causing glucose spikes and subsequent energy crashes that translate into more hunger.
Flavored yogurts and protein shakes are perceived as healthy. However, they contain sweeteners, syrups, or fruit concentrates that spike sweetness and activate the brain’s reward system.
Consequence: your brain interprets that you are consuming a “reward” snack, even though your body doesn’t really need that much energy.
Although alternatives to traditional potato chips, baked chips and flavored microwave popcorn still contain oils, salt, and additives. In addition, their repetitive crunch and reduced volume make the brain think you are eating less than you really are.
How your brain “tricks” you when snacking
The visual satiety effect
When snacks are packaged in large portions or shareable bags, our brain underestimates the amount consumed. This combines with the illusion of healthiness and leads us to eat until we feel physically full, not until our actual energy needs are met.
Dopaminergic reward
Foods with intense, sweet, or salty flavors, even if “healthy,” trigger dopamine release in the brain. This creates a pleasure cycle that makes us want to repeat the experience, even when the body doesn’t need more energy. That is why a handful of sweetened almonds can turn into a binge without noticing.
Mental associations
Many people associate “healthy snacks” with losing weight or taking care of themselves, which reinforces the feeling of permitted indulgence. Your brain interprets: “it’s healthy → I can eat more → it won’t make me gain weight.” This mental association increases the risk of unconscious overconsumption.

Strategies to choose truly healthy snacks
Always check labels
-
Prefer products with minimal ingredients: nuts, seeds, unsweetened dried fruits.
-
Avoid syrups, refined sugars, and hydrogenated oils.
-
Compare calories and portions; a “light” snack can be more caloric than it seems.
Control the portion
Combine nutrients
Mix protein + fiber + healthy fat to maintain satiety:
Alternatives that trick the brain less
-
Carrot or cucumber sticks with guacamole: crunchy, tasty, and with healthy fats.
-
Fresh fruit: naturally sweet, hydrating, and filling.
-
Raw nuts: without sweeteners or roasting.
-
Baked kale chips at home: full control of oil and salt.
