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.
