It sounds like something out of a sci-fi movie or at least a far-out biology class. The idea behind Ultrametabolism: The Simple Plan for Automatic Weight Loss by Mark Hyman, MD, is that your diet can reprogram your genes.
The theory is that when you eat healthy foods, your genes ramp up your metabolism, helping you lose weight. The idea is part of a new field called nutrigenomics.
The concept is pretty basic: Eat healthy, low-fat food. Eating this way generally can help you lose weight, depending on how many calories you take in and how many you burn off.
Exactly how your food and your genes interact, and whether that affects weight loss, isn't clear yet.
What You Can Eat and What You Can't
Expect lots of fruits and vegetables, nuts, beans, whole grains, fatty fish, and lean poultry.
This diet ramps up over 8 weeks. Here's how it works:
- Week 1: You get rid of processed food, sugar, refined carbs, alcohol, and caffeine.
- Weeks 2 to 4: You also cut out wheat, dairy, and eggs. The diet plan claims that here you can lose 6 to 11 pounds.
- Weeks 5 to 8: From now on, you'll follow a long-term healthy eating plan, high in healthy fats, fiber, plant proteins, and a small amount of lean meat. You can start adding back some alcohol and caffeine. How much? Less than three glasses of wine per week and no more than one cup of coffee a day. You'll also take supplements, including calcium, magnesium with vitamin D, and omega-3 fatty acids.
Level of Effort: High
This diet is very limited, especially the first 4 weeks.
Limitations: It will take some effort to avoid unprocessed foods, as well as wheat, eggs, and dairy. You also have to remember to take a lot of supplements. And you may miss coffee and wine.
Cooking and shopping: You can shop and cook like you normally would. Just skip processed and sugary foods.
Packaged foods or meals: No.
In-person meetings: No.
