Dr. Peter Attia is a longevity expert focused on data-driven strategies for enhancing lifespan and healthspan, emphasizing a holistic approach that includes smart eating, training, and lifestyle choices. Unlike fleeting diet trends, Attia's methods emphasize sustainable practices that improve metabolic health, muscle mass, and mental acuity. This guide explores the core principles of Attia's approach to weight loss and overall wellness, integrating his dietary recommendations with exercise and lifestyle adjustments.
Core Dietary Principles of the Peter Attia Diet
The Peter Attia diet has evolved from a traditional ketogenic diet and multi-day fasting to a more balanced approach focused on longevity and healthy living. In his book Outlive, Dr. Attia recommends a diet that focuses on several key principles:
- Optimizing muscle mass (maintaining or building)
- Reducing body fat
- Consuming about 1 gram of protein per pound of body weight daily
- Maintaining energy balance or restriction, depending on your goals
- Eliminating junk food (sugar-sweetened drinks, sweet treats, chips, refined grains, fried foods, pastries, etc.)
- Mindful eating
- Focusing on whole, nutrient-dense foods
- Time-restricted eating
- Choosing a healthy balance of proteins, fiber-rich carbs, and fats
- Monitoring glucose using a continuous glucose monitor (CGM), even if you're not diabetic
- Personalized nutritional approaches and meal planning
- Reducing or eliminating alcohol
- Tracking protein and calorie intake using the Carbon app (or a similar app)
Dr. Attia recommends shopping the outer areas of the grocery store, rather than the center aisles.
While there are no universal guidelines for following Peter Attia's diet, he personally consumes about 2,700-2,800 calories daily and 45-50 grams of protein four times per day. These values reflect Dr. Attia's approach and may not be appropriate for everyone. Continuous glucose monitors (CGMs) in non-diabetic individuals are emerging, and you should discuss them with your healthcare provider to determine if they're suitable for you.
Food Choices and Quality
Dr. Attia encourages nutritious, whole foods, emphasizing fiber-rich carbohydrates, protein, and heart-healthy fats. Protein-rich options include chicken, turkey, fish, seafood, legumes, eggs, nuts, and seeds. Avocados, fatty fish like salmon, olive oil, avocado oil, nuts, seeds, and nut butters are abundant in heart-healthy fats. Examples of nutritious whole carbohydrates include whole grains, fruits, vegetables, legumes, nuts, and seeds.

Foods to Limit or Avoid
Dr. Attia recommends limiting or avoiding (as much as possible) the following foods and drinks:
- Alcohol
- High fructose corn syrup
- Sugar-sweetened drinks
- Other added sugars
- Processed junk foods (candy, chips, pastries, etc.)
- Fried foods
- Refined carbohydrates (white bread, white rice, and others)
He also suggests avoiding foods you're allergic to, intolerant of, or sensitive to, such as gluten, dairy, or soy.
Macronutrient Ratios
Dr. Attia doesn't require specific macronutrient ratios in his diet plans. However, he recommends consuming about 1 gram of protein per pound of body weight daily to maximize muscle growth or maintenance, boost satiety, and reduce or minimize body fat. He encourages balancing protein with fiber-rich carbohydrates (fruits, vegetables, legumes, whole grains, etc.) and healthy fat sources like avocados, fatty fish, nut butter, and olive oil. Dr. Attia suggests you experiment with varying macronutrient ratios to find something that works best for your individualized needs.
Dietary Supplements
Dr. Attia encourages a personalized dietary supplement regimen under medical supervision based on your unique needs. His routine often consists of:
- When Fasting
- Methylated B vitamins
- Slow-absorbing magnesium
- Magnesium L-threonate
- Sodium via bouillon
- During Non-fasts
- Omega-3 fatty acids, EPA and DHA
- Creatine
- Vitamin D3
- B vitamins
- Protein shakes
- Electrolytes
- Probiotics
- Glycine
- Ashwagandha
- Rapymycin
However, Dr. Attia understands that his personalized supplement regimen may not be right for everyone and encourages his followers to only take dietary supplements under the guidance of a medical professional.

Intermittent Fasting Integration
While Dr. Attia used to complete multiple-day fasts, he no longer does so due to intrusiveness, side effects, and potential for poor workouts and lean muscle loss. Now, he focuses more on time-restricted eating when appropriate, flexibility, and listening to his body to optimize longevity. He ensures adequate calories and protein.
Dr. Attia encourages trying varying methods to lose weight or maintain a healthy body weight, including calorie restriction, time-restricted eating, and diet restriction (cutting out bad foods).
Implementing the Peter Attia Diet
Getting Started
Make small dietary changes, a little bit at a time, to transition from a standard American diet to the Peter Attia longevity meal plan. Slowly eliminate junk foods, reduce your total calorie intake (by 500-1,000 daily) if your goal is weight loss, and ensure you're eating 1 pound of protein per pound of your body weight. Track your protein and calorie intake using an app, such as Carbon. Consider total calorie restriction, junk food restriction, time-restricted eating, or multiple strategies based on your goals.
Meal Planning and Preparation
A sample menu based on what Dr. Attia eats in a day includes:
- Breakfast: scrambled whole eggs combined with egg whites and spinach, oatmeal or fruit, and avocado slices or walnuts
- Snack: protein shake made with plant milk, protein powder, and fruit
- Lunch: grilled chicken mixed with leafy greens and freshly sliced vegetables, topped with extra virgin olive oil, lemon juice, and seasonings, OR a ground turkey bowl with cauliflower rice, grilled or sautéed vegetables, and sliced avocados
- Dinner: salmon or shrimp sautéed in extra virgin olive oil, brown rice or quinoa, and steamed vegetables
Dr. Attia typically eats 2,700-2,800 calories daily and 45-50 grams of protein four times per day. Individuals' daily calorie needs will vary based on their weight, gender, age, metabolism, and goals. These meal examples should be appropriately tailored with guidance from a qualified professional.

Recipes and Cooking Tips
Nutritious recipes to consider when following Dr. Attia's diet include:
- High-protein omelet (omit the cheese if necessary)
- Mediterranean ground beef stir fry (you can substitute ground turkey for beef)
- Protein shakes
- Chicken fajitas
- Salmon avocado salad
- Shrimp fajitas
The bottom line is to choose high-protein food, fiber-rich carbohydrates, and healthy fats during meals and snacks.
Monitoring Progress
Monitoring your progress after beginning the Peter Attia diet consists of regularly weighing yourself, tracking your protein and calories, and using a continuous glucose monitor to monitor your blood sugar levels. With the help of your healthcare provider, you can also track other health indicators, such as waist circumference, blood pressure, and cholesterol levels.
Benefits of the Peter Attia Diet
Examples of the potential benefits of the Peter Attia diet based on its core principles include:
- Healthy weight management
- Improved metabolic health
- Enhanced cognitive function
- Potential longevity effects
- Athletic performance optimization
- Muscle growth and maintenance
- Enhanced mental clarity
- Improved biomarkers
Research shows that consuming more protein than the recommended dietary allowance (currently 0.8 grams per kilogram or 0.36 grams per pound) benefits weight loss, improved body composition, and avoiding weight regain. It also helps prevent muscle loss.
Potential Risks and Considerations
When followed correctly, Peter Attia's current dietary advice has few risks. However, nutrient deficiencies may be a concern if you eat too few calories in the long term. Always check in with your healthcare provider if you have a medical condition to determine which specific diet plan best suits your needs. Avoid fasting (unless directed to by your doctor) if you take insulin for diabetes or are pregnant or breastfeeding.
Combining the Peter Attia Diet with Other Lifestyle Factors
To optimize your physical and mental well-being, combine the Peter Attia diet with other healthy lifestyle habits, including:
- Regular exercise: regularly participate in aerobic exercise and resistance training
- Stress management: yoga, tai chi, light walking meditation, or massage
- Sleep optimization: establish a regular schedule that includes 7-9 hours of sleep
- Dietary supplements: only under the supervision of a healthcare professional
Personalize your diet and exercise regimens based on what works best for your unique needs, schedule, food preferences, medical history, and weight and health goals.
Exercise Recommendations
Dr. Peter Attia has a pretty intense exercise regimen himself, but he doesn’t expect you to do what he’s doing. As he says, “I feel so strongly that everybody exercise, that I just think we have to find a way to make sure it becomes natural. So, if you’re someone who hates exercise, but wants to lose weight or live a healthier life, Dr. Peter isn’t going to throw you into his workout plan. Every client is different, so every client needs something different. But, Dr. For many clients, he recommends about four hours a week. This is often called HIIT, or high intensity interval training. Dr. Peter recommends that these intervals be between 3-8 minutes each. Most often, he recommends 4 minutes on, 4 minutes off. These intervals are typically used with cardio exercises, and Dr.
Success Stories and Case Studies
Dr. Attia himself is a success story. After creating and following his own diet, he maintained muscle mass, a healthy weight, exceptional workouts, mental clarity, optimal biomarker numbers, and enhanced mental well-being. Researchers have confirmed the benefits of many of the principles in Dr. Attia's diet plan, including protein-rich diets abundant in whole foods (but lacking in junk foods) and time-restricted eating.
Studies suggest that time-restricted eating helps optimize body weight, glucose tolerance, metabolic flexibility, blood pressure, lipids, gut function, and overall cardiometabolic health. Because Dr. Attia's diet isn't super restrictive, it's usually easy to follow long-term, especially compared to his previous meal plans, which included keto dieting and multiple-day fasts.
Criticisms and Controversies
Criticisms and controversies surrounding Peter Attia's diet plans may have stemmed from his earlier approach to recommending very low-carb diets and multi-day fasting. However, he no longer adheres to these diet principles. There aren't any research studies examining the effects of Dr. Attia's current diet, though the protein-rich, whole-food, calorie-controlled principles he currently uses are backed by science.
The Importance of Managing Weight for Longevity
Managing weight is essential for longevity because it helps prevent chronic diseases such as heart disease, diabetes, and cancer by reducing excess body fat and associated inflammation. Additionally, maintaining a healthy weight promotes overall metabolic health, ensuring efficient functioning of bodily processes and improving quality of life.
Calorie Restriction
The concept of calorie restriction is simple yet powerful-reduce your overall calorie intake. This strategy doesn’t hinge on eliminating specific food groups but rather emphasizes a reduction in the quantity of food consumed. Achieving a caloric deficit is essential for weight loss, encouraging the body to use stored fat for energy, thus promoting weight management effectively.
Dietary Restriction
Dietary restriction involves strategically eliminating specific food groups to reduce overall food intake. This approach can include cutting out dairy, gluten, or significantly reducing carbohydrates, such as in the Keto diet. The underlying logic is that by removing entire categories of food, one naturally eats less.
Time-Restricted Feeding
Time-restricted feeding, a form of intermittent fasting, involves consuming all daily meals within a specific time window, such as eight to ten hours. This method can help limit overall food intake and align eating patterns with the body’s internal clock, optimizing metabolism. Research suggests that TRF can also support cellular repair processes like autophagy, which plays a role in preventing diseases and extending lifespan.
Key Factors for Sustainable Weight Management
It is important to note that no single dieting strategy has been consistently found to be more effective than the others for weight loss and longevity. Research indicates that the most crucial factor across different diets is adherence. The ability to maintain a chosen dietary approach over the long term is the key to success, as consistent adherence ensures sustained benefits and prevents the common issue of diet relapse. The goal of dietary restriction, as well as other dietary strategies, is to find a sustainable eating pattern that promotes health and is easy to maintain long-term. This often means focusing on nutrient-dense, whole foods while ensuring adequate protein intake to preserve muscle mass, especially during weight loss.
Understanding Body Composition
Many of us use body weight or BMI (body mass index) for a quick approximation of our health status. Yet the utility of these metrics is limited because they provide little information about a far more relevant parameter: body composition - and in particular, body fat and its distribution. Body weight and BMI alone do not discriminate between muscle mass (which we want to maintain or increase to promote longevity) and fat mass (which we generally want to keep relatively low). Losing fat mass isn’t necessarily easy, but unfortunately, that struggle pales in comparison to the challenge of keeping it off. This is caused in large part by a hormone called leptin, which is secreted by fat cells and plays a critical role in numerous endocrine pathways and functions, including the regulation of energy homeostasis. Leptin is secreted at levels proportional to body fat and acts as a “satiety hormone” in the brain, causing a reduction in food intake.
Addressing Alcohol Consumption
According to Attia the less alcohol the better. “It’s especially disruptive for people who are overnourished for three reasons: it’s an “empty” calorie source that offers zero nutritional value; the oxidation of ethanol delays fat oxidation, which is the exact opposite of what we want if we’re trying to lose fat mass; and drinking alcohol very often leads to mindless eating,” he says. Some studies suggest moderate levels of alcohol consumption can be beneficial in reducing cardiovascular disease (7). But heavier drinking tends to reverse these effects (8). However, Attia-who enjoys a quality sip of wine or tequila from time to time-has some practical advice. “If you drink, try to be mindful about it. You’ll enjoy it more and suffer fewer consequences,” he says. According to Dr. Peter, there are two really big ways that alcohol can cause immediate damage. First, you don’t want it to keep you from getting a good night’s sleep. Second, you want to make sure it’s not lowering your inhibitions around foods you don’t want to be eating.
Concerns About Weight Loss Drugs
This is one of the reasons to be cautious of weight loss drugs. While weight loss drugs can be a powerful tool to lose weight, they may not be safe or sustainable long term. But, we want to make sure you’re aware of all of the potential benefits and risks. Dr. Peter told us that sometimes, these drugs suppress appetite in a way that makes you less interested in protein-heavy meals. Additionally, since weight loss drugs work as an appetite suppressant, sometimes your appetite comes back with force once you’re off them. If you want to lose weight and keep it off, you may need a more sustainable long-term plan.
