Eat This, Not That? The World’s Most Popular Diets

🌍 Why So Many Diets?

Are carbs the enemy?

Is fat your friend?

Should you eat like a caveman—or a rabbit?

In today’s health-obsessed world, diets aren’t just about losing weight—they’re about identity, ethics, performance, and power. Whether you're fasting, counting macros, or following your blood type, what you eat says something about you.

In this English lesson, we explore the world’s most popular diets, the vocabulary of eating well (or not), and how to use quantifiers and determiners correctly in context.

Let’s dig in. (Get the pun?)

🥗 The Diet Dish: What’s on the Menu?

🔹 1. Vegan & Plant-Based Diets

Veganism avoids all animal products—including meat, dairy, and eggs. Instead, people eat vegetables, fruits, legumes, grains, nuts, and seeds.

Popular among athletes and environmentalists, this diet is linked to lower cholesterol and improved heart health. But it requires planning to avoid nutrient deficiencies—especially B12, iron, and calcium.

🔹 2. Keto Diet

Short for ketogenic, this diet is high in fat, moderate in protein, and very low in carbs. It pushes your body into ketosis, a state where you burn fat instead of sugar for energy.

Many followers report quick weight loss and increased mental clarity—but it’s not easy to sustain and might not work for everyone.

🔹 3. Mediterranean Diet

This flexible, heart-healthy diet includes olive oil, fish, whole grains, fresh vegetables, legumes, and red wine in moderation. It’s based on traditional eating habits in Greece and Italy.

It’s often ranked as one of the healthiest diets in the world—and it’s easy to stick to.

🔹 4. Intermittent Fasting

This isn’t about what you eat but when. The most popular version is 16:8—fasting for 16 hours, eating during an 8-hour window.

People say it helps with fat loss, blood sugar control, and mental focus. But it’s not recommended for everyone, especially those with medical conditions.

🔹 5. Paleo Diet

Also known as the Caveman Diet, Paleo cuts out processed foods, grains, legumes, and dairy—focusing on foods humans ate during the Stone Age: meat, fish, nuts, fruits, and veggies.

Critics say it ignores the benefits of modern agriculture, but fans praise it for cutting sugar and eating more whole foods.

🔹 6. Carnivore Diet 🥩

Think keto, but stricter. This diet allows only animal products: meat, eggs, and animal fats. No fruits, vegetables, grains, or sugar.

Advocates say it reduces inflammation and improves mental clarity. Critics worry about long-term risks and lack of fiber.

It’s the complete opposite of veganism—making it one of the most extreme modern diets.

🔹7. Intuitive Eating
Forget dieting rules. This approach says you should eat when you’re hungry and stop when you’re full—no fasting, no restriction, and no guilt. The goal is to break the binge-diet cycle and respect your body’s natural hunger cues.

🩸 8. Blood Group Dieting – What’s Your Type?

This controversial diet suggests eating based on your blood type (A, B, AB, or O):

• O = more meat (like Paleo or Carnivore)

• A = mostly plant-based

• B = balanced diet

• AB = hybrid of A and B
  There’s limited science to support it, but some followers say it’s helped with digestion and weight. It’s another sign that personalized nutrition is growing in popularity.

🌿 A New Vision of Veganism

It’s no secret that many people have been singing the praises of plant-based diets. There are documentaries, podcasts, and influencers promoting the benefits.

Scientific evidence shows that eating a diet rich in fiber—fruits, vegetables, whole grains, legumes—improves gut health and prevents harmful bacteria.

On the flip side, eating too many sugary drinks and processed fatty foods is linked to obesity, diabetes, and even mental health issues like anxiety.

But is veganism perfect? Not necessarily. Some vegans live on chips, soda, and fake meat. And others fear “too many carbs.”

Still, a well-planned plant-based diet may lower blood pout quality, not just the label.

🧠 Grammar Focus: Quantifiers and Determiners

Quantifiers and determiners are words we use before nouns to show how much or how many of something we are talking about. They help us express quantity, whether we’re talking about healthy snacks, cheat meals, or portion sizes.

Here are some key rules and examples:

• Some is used in positive sentences: I eat some fruit every day.

• Any is used in questions and negatives: Do you eat any snacks? / I don’t have any sugar at home.

• Much is used with uncountable nouns: There isn’t much soda in my diet.

• Many is used with countable nouns: How many diets have you tried?

• A lot of and plenty of can be used with both countable and uncountable nouns:
  I drink a lot of water. / There are plenty of healthy options.

We often use a few and a little to show a small amount. Be careful—few and little without “a” can sound negative:

• I have a few healthy recipes. (positive – enough)

• I have few healthy recipes. (negative – not enough)

Words like each, every, all, both, half, and none help describe total or partial quantities:

• Each person has a different diet plan.

• All of the diets I tried were hard to follow.

• Both versions of the app have great features.

• None of the snacks were healthy.

• Half of the class is trying intermittent fasting.

You can also use phrases like:

• A good deal of (for uncountables): A good deal of research supports this diet.

• A large number of (for countables): A large number of people prefer the Mediterranean diet.

Important tip: With most quantifiers, using “of the” makes it specific.

• I drank some juice. (general)

• I drank some of the juice you gave me. (specific)

Finally, some quantifiers are always singular (like much, each, neither) and others are always plural (like many, few, several). Words like some, all, any, and none can be singular or plural, depending on what follows.

This grammar is especially helpful when discussing nutrition, amounts, and diet plans—so practice it when describing your meals or discussing food habits!
