Low-Carb Diet: A Complete Beginner’s Guide

Low-carb diets have become increasingly popular for weight loss, improving energy, and reducing the risk of chronic disease. But starting one can feel overwhelming. This complete beginner’s guide will walk you through everything you need to know—from what to eat, what to avoid, meal planning, and the science behind it all.

What Is a Low-Carb Diet?

A low-carb diet restricts the intake of carbohydrates, primarily found in sugary foods, pasta, and bread. Instead, you eat whole foods including protein, healthy fats, and vegetables. While carb intake varies, most low-carb diets aim for less than 100–150 grams of carbs per day, with some going as low as 20–50 grams per day for ketosis.

Health Benefits of Low-Carb Diets

Weight Loss: Low-carb diets reduce insulin levels, helping your body burn stored fat for energy.
Improved Blood Sugar Control: Reduces blood glucose and insulin spikes, beneficial for people with diabetes or insulin resistance.
Heart Health: Can reduce triglycerides, increase HDL cholesterol, and lower blood pressure.
Reduced Cravings: Stabilized blood sugar helps reduce cravings and emotional eating.
