Atkins 20, Phase 1: Induction

Atkins 20® Phase 1, also known as Induction, is designed to jumpstart your weight loss. An all-too-common misconception is that Phase 1 of Atkins is the whole program. In reality, it's the key to kick starting your fat burning metabolism. As you move through the diet, you'll find the maximum grams of net carbs you can consume while continuing to lose weight, keep your appetite under control, and stay alert and energized. This is called your personal carb balance.

Phase 1 is all about changing the way your body uses nutrients, so these first few weeks will be essential to your weight loss journey. See details below on Induction and how to get started with your low carb diet.

How Long Does Phase 1 Last?

The length of the Induction phase depends on your weight loss goals. For some, Phase 1 may only last two weeks. However, you may safely follow it for much longer if you have a lot of weight to lose or prefer to lose most of your excess pounds relatively quickly. You'll stay in this phase until you're 15 pounds from goal weight, so Induction may not be necessary for those looking to lose less.

Purpose of Induction

It is important to kick start your weight loss during the first few weeks of a low carb diet. That’s why Atkins Phase 1 works by significantly shifting what you eat before settling in to a more sustainable lifestyle. Sticking to the list of acceptable foods during Phase 1 will help your body shift from burning primarily carbs to burning primarily fat. 

Goal of Phase One

During Induction, it is important to significantly drop your daily net carb intake to an average of 20 grams (no less than 18 and no more than 22). At this intake level, almost anyone begins to burn fat as their primary energy source. The goal is to get your body adjusted to the fat-burning  process so you’ll be able to slowly add more carbs into your diet later on.
