Crisps in the UK are not automatically bad for you. Like most snacks, it depends on how often you eat them, the portion size, and the ingredients used.
In reality, crisps can fit into your diet if you keep things balanced. However, eating them in large amounts can increase your intake of salt, fat, and calories, which may affect your health over time. In this guide, you will learn how crisps are made, how many calories they contain, and how to enjoy them sensibly.
If you enjoy trying different flavours, you can also explore a wide range of options in the snacks and crisps category, from classic potato crisps to bold imported varieties which are popular for their intense flavour.

What Are Crisps in the UK?
Crisps in the UK are usually thin slices of potatoes that are fried or baked until they get crispy and then flavoured. In the US, these are called “chips,” while what Americans call “chips” are known as “crisps” in the UK.
In simple terms, crisps are one of the most popular snack foods across the UK, available in a wide range of flavours and styles. You can find everything from classic salted crisps to hot flavour varieties with intense seasoning.
Key Things That Define Crisps in the UK
- Made from thinly sliced potatoes (or corn, root vegetables, or grains)
- Usually fried in oil, but some are baked
- Flavoured with salt, spices, or seasonings
- Sold in single packs, multipacks, or large sharing bags
Types of Crisps You'll Commonly Find
| Type | Description | Examples |

How Are Crisps Made?
Crisps are made by slicing potatoes thinly, frying or baking them, then seasoning and packaging them for sale.
This simple process is what gives crisps their signature crunch and flavour. The method used, especially frying, plays a big role in how many calories and fats the final product contains.
How Are Crisps Made Step-by-Step?
- 1Potatoes are washed and peeled to remove dirt and skin
- 2Thinly sliced into uniform pieces using industrial slicers
- 3Fried or baked until golden and crispy
- 4Seasoned with salt, spices, or flavourings
- 5Packaged to keep them fresh and crunchy
What Oils Are Used in Crisps?
Most crisps are cooked using oils such as sunflower oil, rapeseed oil, or vegetable oil. These oils help create the crispy texture, but they also add fat and calories, especially in fried crisps.
Kettle-Cooked vs Standard vs Baked Crisps
| Type | How They're Made | Texture | Calorie Impact |
|---|---|---|---|
| Standard Crisps | Fried quickly at a consistent temperature | Light & crispy | Moderate |
| Kettle-Cooked | Cooked in batches at lower temps | Thicker & crunchier | Slightly higher due to longer frying |
| Baked Crisps | Oven-baked instead of fried | Lighter | Lower fat & calories |
Are Crisps Bad for You?
Crisps are not inherently bad for you, but eating them in large quantities regularly can increase your intake of salt, fat, and calories in ways that affect your health over time.
In moderation, crisps can be part of a balanced diet. What matters most is how often you eat them and in what quantities. Here is a breakdown of the key health factors to be aware of.
1. Salt Content
Many crisps are high in salt, which can increase the risk of high blood pressure if consumed regularly. UK dietary guidelines on slat intake recommend that adults eat no more than 6g of salt per day, and a single packet of crisps can take up a noticeable portion of that limit.
Options like Takis Dragon Sweet Chilli can be a great occasional treat - just be mindful of portion size.
2. Fat & Cooking Method
Most crisps are fried, which adds fat and increases calorie content. Fried crisps absorb oil during cooking, raising their overall fat levels compared to baked versions. UK healthy eating guidance highlights that regularly consuming fried foods can increase your overall calorie intake and contribute to weight gain over time.
Classic options like Ruffles Regular are loved for their crunch and texture, satisfying in balanced quantities.
3. Additives and Flavourings
Flavoured crisps often include added ingredients to improve taste and extend shelf life. These are generally considered safe to consume, but having too many highly processed snacks regularly may not support a balanced diet. You can enjoy flavour-packed options like Takis Fuego Rolled Tortilla Corn Chips and Pringles Hot Honey as an occasional treat.
4. Ultra-Processed Foods
Most crisps are classed as ultra-processed foods, meaning they go through multiple stages of processing and contain added flavourings, oils, and stabilisers. General UK healthy eating guidance notes that eating too many ultra-processed foods can lead to a less balanced diet overall.
5. Frequency & Portion Size
The most important factor is how often and how much you eat. Having crisps occasionally in small portions is unlikely to cause harm - but eating large amounts regularly can quickly increase your daily calorie intake. Choosing portion-friendly options like Herr's Regular Crisps can help you manage intake while still enjoying them.
Are Crisps Fattening?
Crisps can lead to weight gain if eaten in large amounts or too often. Weight gain happens when you regularly consume more calories than your body needs — not from crisps alone.
Why Crisps Can Contribute to Weight Gain
- Calories add up quickly: Most small packets contain around 120–150 calories, which multiplies fast across multiple packs a day
- High fat content: Fried crisps are calorie-dense, meaning even small portions are relatively high in calories
- Mindless snacking: Eating crisps while watching multiplyTV or working - without paying attention to quantities - is one of the main reasons they get linked to weight gain
How to Enjoy Crisps Without Gaining Weight?
Stick to small packs
Choose 25g single-serve packs rather than large sharing bags to keep portions in check automatically.
Balance your meals
If you have crisps as a snack, balance it with lighter, nutrient-rich meals throughout the day.
Avoid distracted eating
Pay attention when snacking. Mindless eating from large bags is the fastest route to overconsumption.
Limit frequency
Treat crisps as an occasional snack rather than a daily habit to keep your overall diet balanced.
How Many Calories in a Crisp?
A single crisp contains roughly 8- 10 calories, depending on the type and how it is cooked. However, most people do not eat just one crisp, so it is more useful to look at full packet sizes.
Calories in Crisps: Full Comparison Table
| Serving Size | Standard (Fried) | Baked Crisps | Kettle-Cooked |
|---|---|---|---|
| 1 single crisp | 8 - 10 kcal | 6 - 8 kcal | 9 - 11 kcal |
| 25g small packet | 120 - 130 kcal | 90 - 110 kcal | 125 - 135 kcal |
| 40g standard packet | 190 - 210 kcal | 145 - 170 kcal | 195 - 215 kcal |
| Sharing bag (80–100g) | 400 - 500 kcal | 300 - 380 kcal | 420 - 520 kcal |
Calorie Impact at a Glance
What Makes Some Crisps Higher in Calories?
- Cooking method: Fried crisps absorb oil and are more calorie-dense than baked versions
- Portion size: Bigger packs mean more calories - a sharing bag can easily double your intake in one sitting
- Ingredients: Crisps with cheese, cream, or strong flavourings may have slightly more calories than plain salted varieties
Are Vegetable Crisps Healthy?
Vegetable crisps can contain similar calories and fat as regular potato crisps because they are often fried in oil.
While vegetable crisps sound like a healthier alternative, the reality depends entirely on how they are made and what goes into them.
What to Know About Vegetable Crisps?
- Often still fried: Many vegetable crisps are cooked in oil, just like regular crisps, so fat and calorie levels can be similar
- Sometimes higher in sugar: Vegetables like beetroot or sweet potato naturally contain sugar, which can increase after frying
- Not always lower in calories: Even if made from vegetables, they are still processed snacks and can match regular crisps calorie for calorie
- Baked options can be better: Baked vegetable crisps use less oil and are typically lower in fat
How Many Packets of Crisps Can You Have a Day Without Gaining Weight?
Most people can enjoy 1 small packet of crisps a day without gaining weight, as long as it fits within their total daily calorie intake.
Weight gain depends on your overall calorie intake, not on a single food in isolation. Crisps only become an issue when they push you into a consistent calorie surplus. UK guidance on calorie management confirms that managing your weight comes down to balancing how many calories you eat with how many you burn.
Understanding Your Daily Calorie Needs
| Person | Approx. Daily Maintenance | 1 Packet (25g) as % of Intake |
|---|---|---|
| Average UK woman | ~2,000 kcal/day | ~6% |
| Average UK man | ~2,500 kcal/day | ~5% |
Crisps & Weight: Practical Overview
| Daily Intake | Approx. Extra Calories | Weight Impact |
|---|---|---|
| 1 small packet (25g) | ~125 kcal | Unlikely to cause gain |
| 2 packets daily | ~250 kcal extra | May lead to gain over time |
| 3+ packets daily | 375+ kcal extra | Higher risk of excess intake |
Practical Tips to Keep Your Snacking in Check
- Stick to one small packet (25g) per day as a general guideline
- Avoid eating directly from large sharing bags
- Combine crisps with balanced, nutritious meals
- Do not snack out of boredom or habit, eat when you are actually hungry
- Be mindful of how often crisps feature in your weekly diet
