The 21-day detox, from home

The 21-day detox is Dr. Roni DeLuz's at-home version of the Martha's Vineyard Diet Detox from her bestseller 21 Pounds in 21 Days. It is a 28-day pathway, 21 days of liquid nutrition followed by seven days of reintroducing food, using the 21lbs in 21 Days detox kit, with free access to the online detox community once your kit order is confirmed.

Where the 21-day detox comes from

Before she ever wrote a book, Dr. Roni noticed that guests on her detox retreats on Martha’s Vineyard were losing weight as well as feeling better. She wrote the method down in 21 Pounds in 21 Days: The Martha’s Vineyard Diet Detox, which became a New York Times bestseller. The online detox brings the same program into your own kitchen.

How the 28 days work

Days What you do
1 to 21 Liquid nutrition on a set daily schedule, combining the kit’s products with liquids such as vegetable juices, broths, herbal teas and water
22 to 28 Reintroduction: solid food comes back gradually, starting with the gentlest foods, so you can see how your body responds
Day 29 on PEVY eating (proteins, enzymes, essential fats and vegetables) as your everyday way of eating

The reintroduction week matters as much as the detox. It is where most people find out which foods leave them bloated, tired or foggy.

Doing it safely

A liquid-nutrition detox is a big change for your body. Expect hunger, tiredness or headaches in the first few days as your routine shifts. Talk to your doctor before starting if you are pregnant or breastfeeding, under 18, take medication for diabetes or blood pressure, have kidney or heart disease, or have a history of disordered eating. Never stop a prescribed medication without your doctor.

Questions people ask

What is the 21-day detox?

It is a 21-day liquid-nutrition detox followed by seven days of gradually reintroducing food, based on Dr. Roni's book 21 Pounds in 21 Days. You follow it at home with the detox kit and the online community.

Can you really lose 21 pounds in 21 days?

The book's title reflects what some people on Dr. Roni's retreats experienced. Results vary widely with your starting weight, health and how closely you follow the plan, and much of the early change is water. Focus on how you feel and on the habits you keep afterwards.
