Understanding popular eating styles

There are many different diets today. Some focus on weight loss or maintenance, others support specific health needs, and some are shaped by ethical or environmental values. Among the most common approaches, you’ll find:

• Calorie-counting diets. This traditional approach focuses on managing daily energy intake by tracking calories. People following this diet often choose lower-fat foods and monitor portion sizes to stay within a set calorie target.
• Low-carb diets. Designed to reduce carbohydrate intake, these diets place more emphasis on protein and fats. They are often used for weight management or blood sugar control, though food choices can feel more restricted.
• Plant-based diets. Vegetarian and vegan diets limit or exclude animal products such as meat, dairy and eggs. Many people choose this approach for ethical, environmental or health reasons, and meals often centre around vegetables, grains, legumes and plant proteins.
• High-protein diets. These diets prioritise protein-rich foods to support muscle maintenance and satiety. They are popular with active individuals and gymgoers, as protein plays a key role in recovery and strength development.

Food-focused diet guidance

No matter what kind of diet you're following, it's important to understand something about macronutrients. In a nutshell, all foods can be broken down into protein, fat and carbohydrates. Different diets require you to balance your intake of these three groups in a variety of ways.

In general, you'll find protein in meat and fish, as well as tofu, beans, lentils and pulses. Carbohydrates can be found in rice, pasta, bread, potatoes and other starchy foods, while high-fat ingredients include butter, oil and certain cuts of meat.

As part of your diet, you may want to focus on more specific areas. For example, a sugar-free diet cuts out the white stuff. A high-fibre diet can help keep you regular, while low-fibre meals can fight against bouts of diarrhoea and other digestive problems.

Flexible and alternative diet approaches

Starting a diet is easy, but maintaining it can be a real challenge. Very strict diets, like meat-eating carnivore diets, are almost impossible to follow over a long period of time. It's better to choose something with more flexibility, like these popular diets explained below:

Plant-based and vegetarian eating styles

Choose your own level of vegetarianism, based on your personal preferences. Vegetarians eat eggs and dairy, while vegans shun all animal-based products. A plant-forward diet, also called flexitarian, prioritises plant-based foods, but may still include some meat and fish from time to time.

If you're taking steps toward a plant-based diet, you might want to start with a flexitarian approach. This lets you dip your toe in the waters and get a feel for plant-based eating, without very strict rules. Focus on high-protein veggies and ingredients like legumes and tofu, which will keep you feeling fuller for longer. Exciting ingredients can also help you stick to the diet. For instance, choose exotic sweet potato recipes over regular potatoes.

Lower-carb, higher-protein and structured approaches

Traditionally, a low-carb diet involves carefully counting the exact number of grams of carbohydrates you consume each day. The classic Atkins diet, popular in the 00s, requires dieters to eat no more than 20g of carbohydrates, an extremely low amount. That means cutting out almost all forms of fruit, which is definitely difficult to keep up with.

A more flexible approach involves focusing on high-protein recipes without obsessively counting grams of carbs. You can gently cut down on carbohydrates like potatoes, rice, pasta and bread, while still enjoying generous portions of veggies and snacking on your favourite fruits. Keep it flexible, and you'll find it easier to follow the diet over time.

Making diet guides work for everyday meals

Choose a diet that seems like it will fit well into your lifestyle. It's easiest to start by making small changes, rather than suddenly adopting a completely different way of eating. Gradually changing habits is usually a recipe for success. Each week, pick a fresh diet goal to incorporate into your lifestyle.

Experiment with different recipes to avoid boredom. If you're eating the same meal every day, you'll soon lose interest. A food subscription box can be a powerful tool in your arsenal, giving you interesting recipes to try and providing you with the exact ingredients you need.

Building confidence using diet guides at home

The best diet guides are just that: guidelines, rather than rules. Use them as inspiration, rather than taking them as gospel. Remember, flexibility is key. If you're following a diet that means you can't enjoy a slice of birthday cake or the odd cocktail, you may well end up feeling miserable and falling off the wagon.

You'll be surprised by the impact of small lifestyle changes, like replacing starchy food with leafy veg. Often, a few of these small changes are enough to make you lose weight, increase energy, and feel better — and that can help keep you on track for success in the long run.

Diet guide FAQs

What is a diet guide?

A diet guide tells you what you should eat (and, in some cases, when). The best diet guides give you some flexibility and wiggle room. You're more likely to fall off the wagon if you try a strict diet.

What are the most common types of diets?

The most common types of diet include calorie-counting low-fat diets, low-carb and high-fat diets, and clean-eating diets. There are also diets that are less about weight and more about ethics, like veganism, vegetarianism and religious diets.

Can diet guides help with everyday meal planning?

Yes. A good diet guide gives you a clear outline of what to eat and may also include some recipe ideas. Look for simple, quick-to-prepare meals that you can enjoy on weekday evenings.

Are diet guides suitable for families and shared meals?

They can be, depending on the diet. Growing children have different nutritional needs from adults, so meals may need small adaptations. This allows adults to follow a diet plan while children continue to eat balanced, age-appropriate food.

How do diet guides support long-term meal planning?

Diet guides often provide meal ideas that can be batch-cooked or prepared in advance. Over time, following a guide can also make it easier to plan meals independently and adapt recipes to suit your routine.
