What is a low-carb diet and how does it work?

A low-carb diet reduces carbohydrate intake and increases protein and fat ratios in the diet. It typically means 50-150 grams of carbs daily, which is much less than the average 200-300 grams. Moderate low-carb diets contain 100-150 grams of carbs, while stricter versions are between 20-50 grams. The ketogenic diet is the most extreme version, where you eat less than 20-50 grams of carbs to enter ketosis. It's important to understand that low-carb diets are just a tool for calorie restriction, not a magical fat-burning mechanism.

Does the low-carb diet help with weight loss?

Low-carb diets can help with weight loss, but only if they create a calorie deficit, not because you're eating fewer carbs. Reducing carbs often automatically reduces calorie intake because you eliminate bread, pasta, sweets, and other calorie-dense foods. During the first 1-2 weeks, rapid water loss occurs because carbs store glycogen and water in muscles, but this isn't fat loss. Low-carb diets can stabilize blood sugar and reduce hunger, making deficit maintenance easier. If you eat the same calories on a low-carb diet as with high carbs, you won't lose weight faster.

What can I eat and what should I avoid on a low-carb diet?

Eat plenty of: meats, fish, eggs, cheese, vegetables (especially leafy greens), nuts, seeds, and healthy fats. Whole grains in small amounts are allowed on moderate low-carb diets, but should be avoided on strict versions. Avoid: sugar, sweets, sodas, white bread, pasta, rice, potatoes, and processed foods with high carb content. Fruits are moderate in carbs, berries (strawberries, raspberries) fit better in low-carb diets than bananas or grapes. Dairy varies, Greek yogurt and cheese are good, but milk and sweetened yogurt are higher in carbs.

What side effects can the low-carb diet have?

During the first 3-7 days, "low-carb flu" can occur: headaches, fatigue, irritability, and concentration difficulties. This is temporary while your body adapts to fewer carbs and switches to fat burning. Constipation is common due to reduced fiber content, so it's important to eat lots of vegetables and drink plenty of water. Some people experience performance decline during intense workouts, especially in the first weeks. Long-term strict low-carb diets are hard to sustain and can exclude nutrient-dense foods, leading to micronutrient deficiencies.

Who is the low-carb diet recommended for and who should avoid it?

Low-carb diets work well for insulin-resistant, prediabetic, or type 2 diabetic people because they stabilize blood sugar. They can also help those who are constantly hungry on high carbs and feel better with fewer carbs. Not recommended for type 1 diabetics without medical supervision, as it can cause dangerous ketoacidosis. Not optimal for performance athletes or those doing intense training, as carbs are necessary for peak performance. If you love carbs and a high-carb diet works well for you, there's no need for a low-carb diet to lose weight.

Low-Carb Diet: Complete Guide for Weight Loss and Health

A low-carb diet restricts carbohydrate intake typically to below 50-150 grams daily, increasing protein and fat ratios. Reducing carbs alone doesn't cause weight loss, calorie deficit is still necessary for fat loss. The diet can help stabilize blood sugar, reduce hunger, and make maintaining a deficit easier, but it's not required for weight loss. Low-carb diets can work for many people, but aren't necessary for everyone, and sustainability is more important than perfect macro ratios.
