The diet is split into three phases, each with different foods and physical activities
The Fast Metabolism Diet is a 28-day nutrition program that claims to help you lose weight by speeding up your metabolism. The diet is split into three distinct phases, each with its own recommended foods and physical activities. Each phase lasts for a week and is repeated three times over four weeks.
Phase 1, "Unwind Stress", focuses on reducing stress and calming the adrenal glands. Dieters are advised to eat a high-glycemic, carb-rich diet with moderate amounts of protein and low fat. Vigorous cardio exercises are recommended during this phase.
Phase 2, "Unlock Fat Stores", aims to accelerate metabolism and promote fat burning. This phase involves increasing protein and non-starchy vegetable intake while reducing carbohydrates and fats. Dieters are encouraged to incorporate strength training and weight-lifting sessions during this phase.
Phase 3, "Unleash the Burn", introduces healthy fats back into the diet while still encouraging moderate consumption of carbohydrates and proteins. Stress-reducing exercises such as yoga, meditation, and massage are recommended during this final phase.
It is important to note that while the diet promotes healthy eating, there are no studies proving its efficacy. Additionally, rapid weight loss may not be sustainable or healthy, and consulting a registered dietitian is advised to ensure nutritional needs are met.

The creator, Haylie Pomroy, recommends eating three meals and two snacks per day
The Fast Metabolism Diet is a 28-day nutrition program that promises to help you lose up to 20 pounds in 28 days. It was created by celebrity nutritionist and wellness consultant Haylie Pomroy, who has a background in animal science. The diet claims that eating particular foods at certain times tricks your metabolism into speeding up, resulting in weight loss.
The diet is broken down into three phases, each with its own focus and distinct food lists. The phases are designed to be repeated on a weekly basis for a total of four weeks. Each phase emphasizes different foods and provides recommendations for various physical activities. For example, during Phase 1, you should eat a high-glycemic, carb-rich diet with moderate amounts of protein and low fat. Fats should be avoided during this phase to reduce stress and anxiety and encourage the body to stop storing fat. Phase 2 involves eating a very high-protein, high-vegetable, low-carbohydrate, and low-fat diet, along with strength training. In Phase 3, healthy fats are reintroduced, while still encouraging moderate consumption of carbs and lean proteins.
In addition to the diet, Pomroy recommends engaging in exercise 2 to 3 times per week. Light-intensity exercises such as yoga, stretching, or meditation are advised, as well as at least one day of aerobic exercise or strength training.

The diet aims to boost metabolism and burn fat
The Fast Metabolism Diet, created by celebrity nutritionist and wellness consultant Haylie Pomroy, is a 28-day nutrition program that claims to boost metabolism and burn fat. The diet is based on the idea that eating certain foods at specific times can trick the body into speeding up its metabolism, resulting in increased fat burning and weight loss.
The diet is divided into three distinct phases, each with its own recommended foods and physical activities. These phases are repeated weekly for a total of four weeks. Here's a breakdown of each phase:
Phase 1: Unwind Stress
In the first phase, the focus is on unwinding stress and calming the adrenal glands. Dieters are advised to consume a high-glycemic, carb-rich diet with moderate amounts of protein while avoiding fats. This phase also includes vigorous cardio exercises and aims to reduce stress and prepare the body for weight loss.
Phase 2: Unlock Fat Stores/Build Muscle
The second phase focuses on unlocking stored fat and building muscle. The diet during this phase is very high in protein and vegetables while being low in carbohydrates and fats. Strength training and weight-lifting are recommended to help build muscle and accelerate metabolism.
Phase 3: Unleash the Burn
In the final phase, healthy fats are reintroduced into the diet, while carbohydrates and lean proteins are consumed in moderation. This phase aims to kick the metabolism into high gear and includes stress-reducing exercises such as yoga, meditation, or massage.
While the diet claims to boost metabolism and burn fat, it's important to note that there are no studies proving its efficacy. Additionally, some experts warn that the rapid weight loss promoted by the program may not be sustainable or healthy, and the strict rules may trigger disordered eating behaviours.

The diet has additional rules, such as drinking half your body weight in ounces of water each day
The Fast Metabolism Diet is a 28-day nutrition program that promises to help you lose weight. It was created by celebrity nutritionist and wellness consultant Haylie Pomroy, who has a background in animal science. The diet is based on the idea that eating particular foods at certain times can speed up your metabolism and increase fat burning, resulting in weight loss.
The diet is split into three phases, each with its own focus and recommended physical activities. Phase one is about unwinding stress and calming the adrenals, with a diet that includes high-glycemic fruit, moderate protein, and low fat, along with vigorous cardio. Phase two focuses on unlocking stored fat and building muscle, with a very high-protein, high-vegetable, low-carbohydrate, and low-fat diet, as well as strength training. Phase three is about unleashing the burn and includes healthy fats, moderate carbohydrates, moderate protein, low-glycemic fruit, and stress-reducing activities like yoga and meditation.
In addition to the diet and physical activity guidelines for each phase, the Fast Metabolism Diet includes a few additional rules. One of these rules is to drink half of your body weight in ounces of water each day. This means that if you weigh 150 pounds, you should aim to drink 75 ounces of water per day. Staying hydrated is important for overall health and can also help with weight loss, as it can reduce hunger and increase your metabolism.
Other additional rules of the Fast Metabolism Diet include eating five times per day, eating every 3-4 hours except when sleeping, eating within 30 minutes of waking up, following the phases in order, sticking to the allowed foods in each phase, and exercising according to the phase. It is also recommended to avoid certain foods, such as wheat, corn, soy, dairy, dried fruit, fruit juices, refined sugar, artificial sweeteners, caffeine, alcohol, and fat-free diet foods. While the diet promotes healthy eating, there are no studies proving its efficacy, and some experts warn that the rapid weight loss promoted by the program may not be sustainable or healthy.
