What is the Fast 800?
Understanding the Fast 800: Potential Benefits and Considerations
The Fast 800 diet has gained attention as a rapid weight loss approach. But what does it entail, and is it effective, safe, and sustainable?
The Fast 800 are "a group of doctors, nutritionists and lifestyle specialists who grew frustrated with the increasing gap between what has long been widely accepted as “healthy eating”, and the latest evidence on what actually works." They have created a website that sells shakes, a book, an online program, articles, recipes and more. It looks like a miracle diet, but how effective is it? And can it work for everyone? Maybe, maybe not. Let's break it down with our free and impartial advice.
The Core Idea of Fast 800
The Fast 800 approach centres around three key elements:
Calorie Restriction: The diet involves consuming around 800 calories per day during certain phases. This creates a significant calorie deficit, designed to trigger weight loss.
Time-Restricted Eating: In some phases, your calorie intake is restricted to specific time windows of eating within the day, potentially offering additional metabolic benefits.
Mediterranean-Style Diet: The emphasis is on whole, unprocessed foods typical of the Mediterranean region – fruits, vegetables, legumes, whole grains, fish, and healthy fats like olive oil.
Phases of Fast 800
The program can be broken down into general phases, with varying levels of intensity:
Very Rapid Weight Loss: This initial phase may involve a very low-calorie diet (800 calories per day) for several weeks, aiming for fast weight loss.
Transition (New 5:2): After the initial phase, you might transition to a 5:2 pattern, where you eat 800 calories on 2 days of the week and follow a healthy Mediterranean-style diet for the rest.
Maintenance: The final phase focuses on maintaining your weight loss with a continued emphasis on a healthy, Mediterranean-style eating pattern.
Potential Benefits
Weight Loss: Due to the calorie restriction, the Fast 800 plan can lead to weight loss. For some, the structured approach could be beneficial.
Improved Blood Sugar Control: Some studies suggest the Fast 800 approach may improve insulin sensitivity and potentially benefit those with prediabetes or type 2 diabetes.
Possible Additional Health Benefits: Initial research hints at potential benefits for blood pressure regulation and reducing certain inflammatory markers.
Considerations and Concerns
Sustainability: The highly restrictive nature of the diet can be difficult to maintain long-term, increasing the risk of weight regain.
Rapid Weight Loss: While appealing, very rapid weight loss can also lead to muscle loss and nutritional deficiencies if not properly supervised.
Not for Everyone: The Fast 800 is not suitable for individuals with certain health conditions, those with eating disorders, or pregnant or breastfeeding women.
Professional Guidance: Consulting a doctor or registered dietitian is essential before starting, especially if you have underlying health issues.
In a Nutshell
The Fast 800 approach might offer short-term weight loss benefits for some. However, it's vital to weigh the potential risks against the benefits. Here's the bottom line:
Take a Balanced Approach: Focus on creating a sustainable, healthier eating pattern that fits your lifestyle.
Individual Guidance is Key: There is no one-size-fits-all solution, and seeking professional advice tailored to your specific needs is crucial.
Sustainable Habits Matter Most: Long-term healthy weight management hinges on lasting lifestyle changes that include nutritious eating habits and regular exercise.
Remember, rapid weight loss programs can be tempting, but they rarely offer a long-term solution for health and well-being. Focus on building a balanced, enjoyable lifestyle approach for achieving and maintaining your health goals.
How does it work for weight loss?
The Fast 800 diet works for weight loss primarily through calorie restriction and, to some extent, the metabolic effects of time-restricted eating. Here's a breakdown of how these core elements function:
Calorie Deficit: The Heart of the Matter
The 800-calorie limit on certain days (or phases) creates a significant calorie deficit. This means you're consuming far fewer calories than your body typically burns daily.
To compensate for this energy shortage, your body turns to stored fat as a fuel source, leading to weight loss.
Time-Restricted Eating: Potential Supporting Player
Confining your eating to a specific time window each day (sometimes incorporated in the Fast 800) creates extended fasting periods between meals.
This fasting period may offer additional benefits like boosting your metabolism, improving insulin sensitivity, and aiding in fat burning.
The Role of the Mediterranean-Style Diet
The emphasis on whole, unprocessed foods like fruits, vegetables, legumes, whole grains, and healthy fats contributes to a lower overall calorie intake.
This diet pattern is naturally higher in fibre and nutrient density, promoting a feeling of fullness while supplying essential vitamins and minerals.
How These Elements Interact
The Fast 800 uses a combination of these principles to drive weight loss:
Fast Weight Loss Phase: The initial calorie restriction and potential time-restricted eating creates an aggressive calorie deficit, promoting weight loss.
Transition and Maintenance: The focus shifts to healthier eating patterns with intermittent periods of calorie restriction, aiming to sustain weight loss and prevent rebound.
Important Considerations:
Sustainability: Maintaining a very low-calorie diet long-term can be difficult, increasing the risk of weight regain.
Individual Variation: Results can vary significantly based on starting weight, metabolism, and adherence to the plan.
Medical Supervision: It's crucial to consult a doctor before undertaking the Fast 800, especially if you have underlying health conditions.
While the calorie restriction at the core of Fast 800 is the primary driver of weight loss, the emphasis on a Mediterranean-style diet and potential metabolic benefits of time-restricted eating might offer additional support in the weight loss journey.
Side effects of the Fast 800
Beyond the Weight Loss: Potential Side Effects of the Fast 800 Diet
The Fast 800 diet promises rapid weight loss, but it's essential to be aware of the potential side effects that can accompany such drastic calorie restriction. Here's what you need to know:
Short-Term Side Effects
Hunger and Cravings: Initial adjustment to the 800-calorie limit can trigger intense hunger, cravings, and irritability, especially in the very rapid weight loss phase.
Fatigue and Weakness: A very low-calorie diet can lead to feelings of fatigue, weakness, and difficulty concentrating.
Headaches: Headaches are a common side effect, especially in the initial stages as your body adjusts.
Digestive Issues: Sudden dietary changes, particularly a rapid increase in fiber intake, can cause digestive problems like constipation, diarrhea, or bloating.
Dehydration Risk: Failing to maintain sufficient hydration during the diet can worsen symptoms like headaches and fatigue.
Potential Long-Term Risks
Nutritional Deficiencies: Prolonged severe calorie restriction increases the risk of deficiencies in essential vitamins and minerals.
Gallstones: Rapid weight loss can increase the likelihood of developing gallstones.
Muscle Loss: Along with fat, you may lose muscle mass during rapid weight loss phases, especially if not incorporating sufficient protein and exercise.
Disordered Eating Patterns: For some individuals, restrictive diets can fuel disordered eating patterns or exacerbate existing ones.
Who Should Be Especially Cautious
The Fast 800 diet is NOT suitable for everyone. High-risk groups include:
Those with Eating Disorders: Extreme calorie restriction could be triggering for those who have struggled with eating disorders.
Pregnant or Breastfeeding Women: Adequate nutrition during these stages is crucial, and the Fast 800 is not safe or appropriate.
Individuals with Certain Health Conditions: If you have diabetes, kidney disease, or other chronic health issues, consult your doctor before attempting this diet.
Those on Medications: Very low-calorie diets can interact with certain medications. Physician supervision is essential.
Mitigating Risks
If considering the Fast 800, take steps to minimise potential side effects:
Focus on Nutrient-Dense Foods: When consuming limited calories, prioritize nutrient-rich foods like fruits, vegetables, lean protein sources, and whole grains.
Stay Hydrated: Drink enough fluids throughout the day to prevent dehydration.
Consider a Supplement: Under the guidance of your doctor, a multivitamin might help prevent nutritional deficiencies.
Listen to Your Body: If you experience severe or persistent side effects, stop the diet and seek medical advice.
The Takeaway
While the Fast 800 might result in short-term weight loss, it's crucial to weigh the potential side effects against the benefits. Always keep a sustainable approach to weight management focused on:
Balanced Diet: Eat whole, nutritious foods for long-term health.
Regular Exercise: A vital component for weight loss and overall well-being.
Professional Guidance: Consult a doctor or registered dietitian for individual weight loss advice, especially if you have underlying health concerns.
Remember, weight loss is important, but your overall health and well-being is more important. Always aim to lead a healthy lifestyle and get exercise, either on the fast 800 or not. regular intermittent fasting isn't for everyone, there are alternatives if you want to lose weight.

The Benefits of Intermittent Fasting:
Exploring Intermittent Fasting: Potential Benefits Beyond Weight Loss
Intermittent fasting (IF) has become a popular approach for weight loss and overall health. It involves cycling between periods of eating and fasting. Let's delve into the potential benefits of IF, looking beyond its well-known role in weight management.
How Intermittent Fasting Works
IF comes in various forms. Here are some common approaches:
Time-restricted Eating: Limiting food intake to specific hours of the day (e.g., only eating between 12pm and 8pm).
5:2 Method: Eating normally for 5 days of the week and significantly restricting calories on 2 days.
Alternate-Day Fasting: Alternating between days of regular food intake and days of fasting or severe calorie restriction.
Potential Benefits of Intermittent Fasting
Weight Management: During fasting periods, your body shifts to using stored fat as energy, facilitating weight loss.
Improved Insulin Sensitivity: IF can increase the body's responsiveness to insulin, helping regulate blood sugar levels. This could offer benefits for those with prediabetes or type 2 diabetes.
Cellular Repair: Fasting periods may trigger autophagy, a process where the body clears damaged cells and regenerates healthier ones.
Reduced Inflammation: Some studies suggest IF might lessen chronic inflammation, linked to various health conditions.
Potential Heart Health Benefits: IF may modestly improve blood pressure, cholesterol levels, and other markers of cardiovascular health.
Brain Boost: Animal studies hint at potential benefits for cognitive function and protection against neurodegenerative diseases, although more research in humans is needed.
Important Considerations
Not a Magic Bullet: While IF offers potential benefits, it's not a one-size-fits-all solution and requires careful consideration.
A 1x1
Approach is Key: Consulting a doctor or registered dietician is crucial, particularly if you have underlying health conditions.
Diet Quality Matters: Focus on a balanced, nutritious diet during eating periods for optimal health.
Potential Side Effects: IF may cause temporary side effects like hunger, irritability, or fatigue, particularly during the initial adjustment.
In Summary
Intermittent fasting could be a valuable tool in your wellness arsenal. While its weight loss benefits are well-documented, its potential extends beyond the scale. From cellular health to heart health, IF may offer diverse advantages. Remember, it's essential to take a sustainable approach alongside a balanced diet and seek professional guidance for the best results. Steady weight loss is always best - and remember, speak with your healthcare provider or GP if you are thinking of any diet or weight loss program.
