The Renaissance Periodization (RP) diet is a scientifically formulated approach designed to help individuals achieve their health, fitness, and performance goals. Developed by Dr. Mike Israetel and his team, this evidence-based system translates complex sports science into actionable nutrition and training plans suitable for everyone from first-time lifters to world-class athletes. The diet is grounded in peer-reviewed research and data from over 175,000 app users, ensuring its recommendations are constantly refined and effective.
Understanding the RP Diet
The RP diet involves calculating daily calorie, protein, carbohydrate, and fat needs based on an individual’s unique requirements and goals. It is a comprehensive program that provides a structured, evidence-based approach to nutrition. The RP diet aims to optimize body composition, athletic performance, and overall health by focusing on nutrient-dense foods and proper macronutrient intake.

Setting Realistic Expectations
One of the most important aspects of starting the RP diet is setting realistic expectations. Many people are often too hard on themselves in terms of the results they expect to see. For example, if you and a friend start the diet at the same time, your friend might lose weight faster initially. However, this could be due to factors like water weight loss from a previous cheat weekend. It's crucial to focus on your own progress and not compare yourself to others, as you can only control your own outcome.
The recommended rate of weight loss is about 1-2 lbs per week. For very small females, this might be 0.5-1.5 lbs per week (7-15 lbs per 3 months), while for individuals over 225 lbs, it could be 1.5-2 lbs per week. Slower weight loss is generally preferred because it is more sustainable and less likely to negatively impact performance and strength.
Starting with the Base Diet
It is always recommended to start with the base diet to allow your body to acclimate to the new structure. The goal of the base diet is to help you get used to the diet, especially if you are coming from a non-structured approach, and to establish a baseline caloric intake. The idea is to eat as much as possible while losing weight and as little as possible when looking to gain weight. There are no bonus points for dieting harder than you need to.
Whether you lose weight on the base diet depends on your starting point. If you had a strict diet before starting, you might not lose weight, and that’s perfectly fine. The base diet's primary goal isn't necessarily weight loss, but it’s entirely possible to lose weight during this phase.

Addressing Hunger and Cravings
Hunger is often a significant challenge when dieting. Unfortunately, if you're trying to get leaner than where your body naturally wants to sit, hunger is part of the process. While there's no way to completely eliminate hunger, there are strategies to curb it.
Tips to Curb Hunger
Drink Lots of Fluids: Sparkling ice, diet soda, and plenty of water can help satisfy oral fixation and create a feeling of fullness.
Eat Extra Veggies: High-volume, low-calorie foods like vegetables can help you feel more satiated.
Use Breath Mints: Sucking on breath mints can help distract from hunger pangs.
Choose High-Volume Foods: Opt for foods like butternut squash or sweet potatoes, which tend to be more filling than rice or pasta.

Consider Sugar-Free Options: Sugar-free jello can be a low-calorie way to satisfy sweet cravings.
It's important to remember that these strategies are about endurance and are often a short-term solution. Most people can't sustain extreme leanness in the long haul, so finding a balance is key.
Monitoring Progress and Adjustments
Your weight will fluctuate regardless of your diet compliance. It's recommended to weigh yourself only twice a week in the morning, following a similar routine, to get weekly trends. There are many reasons for bodyweight to increase due to water weight fluctuations, so it’s not a good idea to weigh yourself every day or more than once per day. Focus on weekly trends rather than daily fluctuations.
For females, it's sometimes better to skip weighing in around your monthly cycle or to record the data to understand what to expect each month. The goal is to avoid getting caught up on weight fluctuations that are outside of your control.
If you’re not seeing the desired results, it might be time to diet harder. This means adjusting your calorie and macronutrient intake based on your RP diet template.
RP Diet and Training
The Renaissance Periodization diet is designed to be used in conjunction with an exercise program. Cardiovascular exercise can also be incorporated, focusing on moderate-intensity steady-state (MISS) and high-intensity interval training (HIIT) for optimal results.
Integrating Physique Training
For individuals who want to incorporate more physique training, it’s often best to focus on a balanced approach that combines strength training with targeted exercises for specific muscle groups.
Example:
For a female client who wants to improve her physique, particularly her stomach, hips, quads, and glutes, a basic 4-day split can be effective. This could include:
- Day 1: Upper Body Strength (e.g., bench press, overhead press, rows)
- Day 2: Lower Body Strength (e.g., squats, deadlifts)
- Day 3: Upper Body Hypertrophy (e.g., bicep curls, tricep extensions, lateral raises)
- Day 4: Lower Body Hypertrophy (e.g., lunges, glute bridges, hamstring curls)
Adding "fluff" exercises can help target specific areas. The physique changes will come as long as the weight comes off.
Example Meal Plan
Here is an example of a meal plan incorporating RP principles:
- Breakfast: Oatmeal with protein powder and berries
- Lunch: Grilled chicken salad with mixed greens, vegetables, and a light vinaigrette
- Dinner: Turkey and sweet potato chili
- Snacks: Greek yogurt with fruit, a handful of almonds
RP Diet Templates: Original vs. Simplified
Renaissance Periodization offers both original and simplified diet templates to cater to different needs and preferences.
Original RP Diet Templates
- Meal Number: 6 meals per day, including a workout shake.
- Meal Variation: Meals vary based on workouts.
- Diet Phases: 3 calorie-reduction phases: Fat Loss 1, 2, and 3.
- Measuring: Specifies the number of grams of proteins, carbs, and fats to eat in every main food group for each meal, requiring some math.
- Macros: Tailored to athletes, allowing for fat loss while optimizing sport performance.
Simplified RP Diet Templates
- Meal Number: 3 main meals per day, no workout shake, and an optional snack.
- Meal Variation: Meals do not vary based on workouts.
- Diet Phases: 2 phases: Weight Loss 1 and 2, making them less precise but easier to get through.
- Measuring: Features a diagram for each diet phase that shows the relative amount of food from each food group allotted during that phase.
- Macros: Altered macros to simplify the diet while still promoting fat loss.
The simplified templates were designed to bring the effectiveness of the originals to more people by making the process simpler with fewer meals, simpler foods, and basic measurement instructions without the need for math.
Potential Health Risks and Considerations
While the RP diet is generally healthy, it’s essential to follow it properly to avoid potential health risks. Adequate protein intake is emphasized to support muscle growth and repair, but it’s crucial to ensure a balanced diet with sufficient nutrients. Individuals with pre-existing kidney conditions should consult with a healthcare provider before starting the diet.
Rapid Weight Loss Diets
It’s important to distinguish the RP diet from rapid weight loss diets, which involve losing more than 2 pounds (1 kg) per week over several weeks. Rapid weight loss diets often require eating very few calories and are generally not recommended for long-term use.
Types of Rapid Weight Loss Diets:
Very-Low-Calorie Diets (VLCDs): These diets use meal replacements like formulas, soups, shakes, and bars instead of regular meals. A VLCD is only recommended for adults with obesity who need to lose weight for health reasons and should be supervised by a healthcare provider.
Low-Calorie Diets (LCDs): These diets usually allow about 1,200 to 1,500 calories a day for women and 1,500 to 1,800 calories a day for men. An LCD may use a mix of meal replacements and regular food and should also be supervised by a healthcare provider.
Time-Restricted Eating: This involves limiting the number of hours per day that you can eat, such as the 16:8 method where you eat all your meals during an 8-hour period.
Fasting: This involves periods of not eating, such as the 5:2 system with 2 days a week of fasting or VLCD and 5 days a week of eating your normal diet.
Risks of Rapid Weight Loss:
- Loss of muscle, water, and bone density
- Gallstones
- Gout
- Fatigue
- Constipation
- Diarrhea
- Nausea
People who lose weight quickly are also more likely to regain the weight quickly, leading to other health problems. In general, a rapid weight loss diet is not safe for children, teens, pregnant women, or older adults unless recommended by a healthcare provider.
