What Is a Low-Carb Diet?

A low-carb diet is exactly what it sounds like — a way of eating that limits carbohydrate intake, focusing instead on proteins, healthy fats, and non-starchy vegetables.

Carbohydrates include sugar, bread, rice, pasta, potatoes, sweets, and many packaged foods. While carbs are an important energy source, excess intake — especially refined carbs — can lead to weight gain, insulin resistance, and other metabolic issues.

There are different levels of low-carb eating:

• Moderate low-carb: 100–150g of carbs/day

• Low-carb: 50–100g of carbs/day

• Very low-carb or keto: under 50g of carbs/day

How Does It Help With Weight Loss?

Here’s how a low-carb diet supports weight loss:

1. Reduces Hunger
Protein and fat are more filling than carbs. By focusing on these, you feel full longer and naturally eat less without counting calories.

2. Lowers Insulin Levels
Carbs raise insulin, a hormone that helps store fat. When you eat fewer carbs, insulin levels drop, which can make it easier for your body to burn stored fat for fuel.

3. Encourages Fat Burning
With fewer carbs, your body switches from using glucose (sugar) as its primary energy source to burning stored fat. This process is called ketosis (in very low-carb diets) or fat adaptation in moderate ones.

4. Reduces Water Retention
Carbs cause the body to retain water. Cutting carbs often leads to rapid water weight loss in the first week, giving you a quick motivational boost.
