FROM NEW YORK TIMES BESTSELLING AUTHOR DR. JASON FUNG: The landmark book that is helping millions around the world achieve natural weight loss. The Obesity Code is a groundbreaking, science-based guide to lasting weight loss that goes beyond "calories in, calories out." Instead of blaming lack of willpower, practicing physician Dr. Fung explains how hormones--especially insulin--drive weight gain, cravings, and stubborn belly fat. If you've tried countless diets and always regain the weight, this book shows you why, and what to do differently. Drawing on clinical research and real patient success stories, The Obesity Code reveals how insulin resistance and constantly elevated insulin levels lock your body into fat-storage mode. Traditional low-fat diets, frequent snacking, and severe calorie restriction can actually make things worse, slowing your metabolism and increasing hunger. Dr. Fung shows you how to work with your biology instead of against it, so you can lose weight naturally and improve your metabolic health. Dr. Fung is often cited as the founder of intermittent fasting for weight loss. Rather than another restrictive fad, intermittent fasting is a flexible, practical tool you can adapt to your lifestyle. You'll learn:
- How intermittent fasting helps lower insulin and unlock stored fat
- Different fasting methods (including 16:8, 24-hour fasts, and more)
- How to start safely and manage hunger, social events, and busy days
In addition to when you eat, Dr. Fung explains what to eat for sustainable, natural weight loss. The Obesity Code emphasizes:
- Whole, unprocessed foods instead of ultra-processed snacks
- Minimizing sugar and refined carbohydrates that spike insulin
- Including healthy fats, quality protein, and fiber-rich vegetables
- A realistic, adaptable approach rather than a rigid, one-size-fits-all diet
Whether your goal is to lose weight, reduce belly fat, reverse pre-diabetes or type 2 diabetes, or simply improve overall health and wellness, The Obesity Code provides clear explanations and actionable steps. It's ideal for readers who want to:
- Lose weight naturally
- Learn how to intermittent fast for weight loss
- Reverse insulin resistance
- Gain science-backed weight loss information
If you're tired of yo-yo dieting, conflicting diet advice, and short-term fixes, The Obesity Code offers a clear, evidence-based roadmap to lasting change. Learn how to rebalance your hormones, use intermittent fasting effectively, and finally achieve the healthy, sustainable weight loss you've been looking for.

Better than most!
Size: 1 add-on extender, Configuration: without eero Plus
I found that this extender works better than most in that it seamlessly boosts the signal without having to switch networks. The set up was super simple and easy, just plug and play basically. Does exactly as advertised, only about a 30% reduction in speed.

Almost perfect...
Size: 1 router + 2 extenders, Configuration: without eero Plus
I needed to extend my wireless reception for my home office. This was recommended by the cable guy and was easy to install. Instead of just picking up a signal and patching it through, it creates a web in my home and extends the wi-fi not only to my office, but upstairs as well.
It works with my Comcast modem and provides much greater speed and coverage in my home. It's not perfect as I still get occasional freezing when on video calls, but unless I want to move my office to the dining room this will have to do.
I don't know how much this should cost, but I had a little bonus money so I spent it on this upgrade. It seems to be worth it.

Super Easy Setup & Great Coverage
Size: 1 add-on extender, Configuration: without eero Plus
This was incredibly easy to set up. The app walked me through everything step by step and within just a few minutes the extender was connected and working. I’m not super techy, so I really appreciated how simple and straightforward the process was.
I added this to help improve Wi-Fi coverage in parts of the house that normally had weaker signal, and it made a noticeable difference right away. Everything feels faster and more reliable now, especially when streaming or using multiple devices at once.
Definitely a great option if you want to extend your coverage without dealing with a complicated setup process.

Works with Eero 7 router and easy setup
Size: 1 add-on extender, Configuration: without eero Plus
Fabulous!!
Fortunately I read many reviews and learned a few things before buying this excellent product. I have a recently installed Eero Pro 7, and this works great.
One review I read mentioned it might take a bit of time for your device to recognize use the signal from the extender instead of the router. That was true for me. Give it 30 minutes or so and you will be happy.
Another review talked about having the same Eero router I have, so I knew it would work for me.
And finally, remember this… extenders do not increase speed per se, they improve the strength of the signal. It is improved signal strength that is allowing your device to operate better. Weak signal, slower speed. String signal, faster speed.
Plug it in, open the app, tap to add a device and follow the very, very simple instructions and voila, connected.
Rather than pay the extra $21/mo the IP wanted for me to rent the nodes, for the price of 3 months rental I own the extender.
Excellent product

Easy-to-add hub to for an existing Eero system
Size: 1 add-on extender, Configuration: without eero Plus
Ok, so I am NOT tech-y at all—but fortunately Eero caters to my ilk!
I installed an Eero wireless "mesh" system when we moved into our home and it came with three hubs to extend the coverage of the wifi throughout the home. That system was very easy to set up and control with an app, even for those without high-tech capacity like myself.
Now, the good thing about a Midcentury home is that it is built insanely well—but the same thing that makes it soundproof and sturdy is also the thing that makes it a little troublesome when it comes to wifi coverage. I made my son a "kid-cave" out of the outdoor shed, which is about 15 feet away from the house. And as good as the Eero was inside the home, it was not able to deliver a consistent signal through the solid concrete walls to the shed.
After much grumping from my 13-year-old gamer, I ordered one more extender hub to solve the issue. It arrived in a timely manner, and I brought it into the shed and plugged it into the wall. Fortunately for me, it was super easy to add this new hub to the existing system. All it took was one click in the app, and in less than a minute, the shed had full, high-speed wifi coverage like the rest of the home.
I cannot recommend Eero enough - it is sleek, small and powerful, and the system is easily extended to suit all your wifi needs.
