Why Engage Groups Work
Many people don’t struggle because they lack information. They struggle because change is hard to sustain alone.
Engage 2.0 combines the science of iDiet with the structure and accountability of a live group experience — creating optimal conditions to succeed.
Engage 2.0 Helps You:
- Stay consistent week to week
- Apply the material to real life
- Get questions answered as they arise
- Learn from others facing similar challenges
- Maintain accountability
- Solidify your new healthy lifestyle, based on best-in-class science
How It Works
1. Learn the iDiet™ Method
You’ll follow the full iDiet curriculum, grounded in research on hunger control, food preferences, and sustainable weight management.
2. Meet Weekly in a Live Small Group
Each week, you’ll join a live group session to:
- Review key concepts
- Ask practical questions
- Work through common challenges
- Stay accountable and engaged
Group size is intentionally limited so sessions remain interactive and supportive.
3. Apply What You Learn
Between sessions, you’ll use the iDiet tools, meal plans, custom website, help library, and guidance to build habits that reduce hunger and support steady progress.
4. Maintain for Life
Your newly retrained brain will help you make better choices — if you continue to apply iDiet principles.
And you get lifetime access to everything.

It Doesn’t Feel Like A Diet
As our iDieters will tell you, the iDiet is a new way of eating for life, a program that you stay with because it makes sense… and makes you feel so good!
“I’ve lost weight I’ve had almost my entire life and I’ve become the person I thought I might be, and the iDiet really enabled that.”
— Dave, lost 50 pounds at midlife
“I ended up losing 45 lbs! I never thought that I’d see that number again on the scale. I was hoping to lose 20 to 30 lbs. And you know, at 30 pounds I said: ‘I think I can do more.’ And so I just continued on, and it works.”
— Nicole, lost 45 pounds at midlife
“I have the ability to manage my life and manage my lifestyle and manage my weight. What a release…what a great gift the iDiet program gave me.”
— Aleks, lost 30 pounds in her late 20’s

As Seen In
The top 12 questions we receive:
1. Is this plan safe and sustainable for me? The iDiet is designed to work with our biology and the challenges of the modern food environment, making it tailored for long-term sustainability. It aims for a safe and sustainable approach to weight loss without resorting to extreme or harmful side gimmicks.
2. Does this plan take into account my individual needs and hormones? The iDiet acknowledges that everyone experiences hunger differently due to your unique neurobiology and history, and your hunger signaling hormones. The program aims to help individuals manage these sensations and signals effectively through real food and smart meal composition. The program is shown to be equally effective for women past menopause vs younger women, and men.
3. Will I be able to lose weight and keep it off in the long term? The iDiet focuses on controlling hunger through strategic snacking, balancing the right amounts and types of nutrients, and eating the right foods to stay full on fewer calories. By recommending specific, calorie-controlled snacks, following our EasyPlans and using Free Foods when hungry, the program aims to keep hunger at bay, which can aid in long-term weight management. The emphasis is on understanding and managing hunger and metabolism for sustainable weight loss through healthy eating. Once you learn to “control the controls” and to prefer weight-friendly foods, then weight management becomes second nature.
4. Is this plan affordable and realistic for my lifestyle? The iDiet emphasizes the importance of realistic expectations and avoiding gimmicks and fad foods. We use real foods, we do not sell prepackaged shakes and bars or require specific manufactured foods. We do help you find the foods best for weight management. Our EasyPlans also promote good planning which virtually eliminates food waste, while simplifying shopping and planning.
5. Does this plan offer support and accountability? The iDiet offers guidance on all aspects of dieting, from snacking to meal planning. Dieters receive more than just recipes; they get assistance in unraveling a lifetime of food habits and intentionally constructing a new healthier relationship with food.
6. What are the potential side effects of this plan? The iDiet cautions against starvation diets and extreme dietary practices, which can have harmful effects. It aims to provide weight loss without resorting to harmful behaviors, taking a moderate approach based in responsible scientific research — not fads. The only expected side effects are better health, more energy, and good weight management without excessive hunger.
7. How much weight can I expect to lose per week or month? Dr. Roberts shows that responsible research has found that 1% of bodyweight per week — about a maximum of two pounds of adipose tissue per week — is the maximum sustainable weight loss one can expect or hope for. Diets promising more than this are likely making false claims as well as setting you up for metabolic problems.
8. What foods will I be able to eat on this plan? The iDiet emphasizes high fiber foods, moderately high protein meals, low GI carbs (slow carbs), and high-volume foods. Whole grain or high-fiber carbohydrates, such as beans, whole fruit (not juices), nuts, seeds, and whole grains, are encouraged, as well as lean proteins, low-fat or non-fat dairy, and a wide variety of vegetables.
9. What foods will I need to avoid? The program teaches about the negative impact of sugary and hyper-processed foods of low nutritional value, which increase inflammation and metabolic dysfunction. Liquid calories, like juice, are avoided as not being hunger-satisfying and should also not be included in a weight-management diet. We also discourage alcohol for the first 6-8 weeks.
10. How much exercise will I need to do? While exercise is beneficial, the iDiet emphasizes that it’s not enough on its own for significant weight loss, and can even increase hunger. Our focus should be more on food. Once you feel more energetic and a bit lighter, most iDieters find that they naturally wish to increase their activity.
11. Is this plan flexible enough to accommodate my dietary restrictions and preferences? The iDiet offers flexibility in its approach, focusing on controlling hunger through various heathy foods. We have EasyPlan options for vegetarians, vegans, and those who must avoid wheat.
12. Does this plan have a good track record of success? The iDiet is the only weight loss program with randomized controlled trials showing exceptional results, with 6x the average weight loss of other programs clinically studied.
