What You'll Learn

Intermittent fasting is a diet planner, not a diet
The 75 Hard challenge, created by Andy Frisella, is a separate concept that incorporates intermittent fasting as one of its components. It is a 75-day rigorous challenge that focuses on mental toughness, discipline, and lifestyle changes. The challenge includes following a diet of choice, such as keto, paleo, or intermittent fasting, without any cheat meals or alcohol. Additionally, it involves daily tasks such as two 45-minute workouts (one outdoors), reading 10 pages of a non-fiction book, taking progress photos, and drinking a gallon of water.
The challenge emphasizes consistency and commitment, with participants required to restart from day one if they break any of the rules. While it provides a structure for diet and exercise, it does not prescribe a specific diet plan or meal choices. The diet chosen by participants can vary based on their goals and preferences but must be adhered to strictly for the entire 75-day period.
Intermittent fasting, in the context of the 75 Hard challenge, serves as a tool to help individuals structure their meal timings and create a disciplined approach to their diet. It is not a diet in itself, as it does not provide guidelines on what foods to consume or restrict. Instead, it is a planning method that can be incorporated into various diets to help individuals achieve their health and fitness goals.
The effectiveness of intermittent fasting as a diet planner is supported by personal testimonies and experiences shared online. Many individuals find that the structured approach of intermittent fasting helps them stay disciplined and focused on their dietary choices. It provides a framework for meal timings, allowing individuals to plan their meals and snacks within the designated eating window. This structure can be particularly beneficial for those who struggle with impulsive eating habits or those who want a simplified approach to meal planning.

75 Hard is a mental toughness program
The rules of the program include:
- Following a diet with zero alcohol and no cheat meals. The diet itself can vary depending on the participant's goals and can include intermittent fasting, keto, plant-based, or paleo options.
- Completing two 45-minute workouts a day, one of which must be outside.
- Reading 10 pages of a non-fiction or self-help book each day.
- Drinking a gallon of water every day.
- Taking a progress picture every day.
The program is designed to be challenging, and if a participant misses a day or any of the rules, they must start over from day one. This strict rule is intended to prevent participants from compromising the rules, which can lead to quitting the program. While the program has gained popularity on social media, there is limited evidence regarding its safety and sustainability.
Intermittent fasting is a popular diet choice for participants of the 75 Hard program. It involves reducing the number of hours one consumes food during the day. Some individuals choose to do a 16/8, 18/6, or 20/4 fast, depending on what is achievable for them. It is important to note that intermittent fasting does not specify what to eat during the eating window, and individuals must define a diet plan that works for them.
Overall, the 75 Hard program is a mental toughness challenge that aims to build discipline and transform participants' lives by encouraging healthy eating and fitness habits.

Intermittent fasting can be combined with the 75 Hard challenge
The challenge consists of six non-negotiable rules:
- Follow a diet with zero alcohol and no cheat meals. The diet itself is up to the participant and can vary depending on their goals. This can include intermittent fasting, keto, plant-based, or paleo diets.
- Complete two 45-minute workouts a day, one of which must be outside.
- Read 10 pages of a non-fiction/self-help book. Audiobooks do not count.
- Take a progress picture every day.
- Drink a gallon of water every day.
Intermittent fasting involves reducing the number of hours that one takes food during the day. Some people find that a 20/4 or 18/6 fasting schedule works well for them, while others prefer a more achievable 16/8 schedule. It is important to define a diet and then follow it for 75 days straight. If a more extended fasting period is not realistic for you, it is better to choose a shorter fasting window that you can stick to for the entire challenge.
Combining intermittent fasting with the 75 Hard challenge can be challenging due to the two daily workouts and the need to feed after a workout. However, some people have successfully combined the two by focusing on keeping their protein intake high during their eating window.

Intermittent fasting is not sufficient for the 75 Hard challenge
Intermittent fasting (IF) is a popular dieting approach that involves eating within a specific time frame each day. While it can be an effective tool for weight loss and improved health, it may not be sufficient for the 75 Hard challenge. The 75 Hard challenge is an intense wellness program that aims to bring about transformational changes in mental toughness, discipline, and overall lifestyle. It consists of several strict rules that must be followed for 75 days without any breaks, and failing to adhere to even one rule means starting the challenge over.
One of the rules of the 75 Hard challenge is to follow a diet of your choice, which can include intermittent fasting. However, intermittent fasting alone does not address all the aspects of the challenge. While it provides a structure for meal timing, it does not specify what foods to eat during the eating window. The 75 Hard challenge emphasizes the importance of healthy eating, and participants are expected to follow a strict meal plan for 75 days. Therefore, combining intermittent fasting with a nutritious and well-planned diet that aligns with one's goals is crucial for success in the challenge.
Additionally, the 75 Hard challenge involves completing two 45-minute workouts per day, one of which must be done outdoors. This rigorous exercise regimen demands proper nutrition to support muscle retention and recovery. As such, participants must carefully consider their dietary choices to ensure they are consuming adequate calories and nutrients to fuel their workouts. Intermittent fasting may not provide sufficient flexibility to accommodate the nutritional needs of individuals engaging in such intense physical activity.
Furthermore, the 75 Hard challenge is not solely focused on diet and exercise. It also includes other rules such as reading 10 pages of a non-fiction or self-help book daily, taking progress pictures, and drinking a gallon of water every day. These additional tasks contribute to the overall goal of fostering mental toughness and discipline. Intermittent fasting, while a useful dietary tool, does not inherently incorporate these essential elements of the challenge.
In conclusion, while intermittent fasting can be a valuable component of one's dietary strategy during the 75 Hard challenge, it is not sufficient on its own. Participants should combine intermittent fasting with a well-planned diet that supports their nutritional needs, workout regimen, and overall health goals. Additionally, they must incorporate the other rules of the challenge, such as daily reading and progress tracking, to achieve the desired transformational changes in mental toughness and discipline.

Intermittent fasting is a popular diet trend
One of the key appeals of intermittent fasting is its flexibility. Unlike traditional diets that dictate specific foods or meal plans, intermittent fasting focuses solely on the timing of meals. This means that individuals can choose the dietary approach that suits their preferences and goals within their designated eating window. For example, some may opt for a keto, plant-based, or paleo diet during their eating window, depending on their personal choices.
The popularity of intermittent fasting has led to its integration into various lifestyle and fitness challenges, such as the 75 Hard Challenge. This challenge, created by Andy Frisella, is a 75-day program that combines elements of nutrition, fitness, and self-improvement. It includes rules such as working out twice a day for 45 minutes, reading 10 pages of a non-fiction book, taking daily progress pictures, and, most notably, sticking to a chosen diet with zero cheats.
Participants in the 75 Hard Challenge are allowed to pick their diet, and intermittent fasting has been a popular choice. Many individuals have shared their experiences combining the challenge with intermittent fasting protocols, such as 16/8, 18/6, or 20/4 fasting schedules. This involves aligning their fasting and eating windows with their workout routines to optimize results.
While intermittent fasting may offer flexibility and health benefits, it is important to approach it with caution. As with any dietary change, it is advisable to consult with a healthcare professional or registered dietitian to ensure it is safe and suitable for your individual needs. Additionally, it is worth noting that extreme, short-term lifestyle changes like the 75 Hard Challenge can be challenging to maintain, and relapsing into old habits afterward is common. Therefore, it is essential to consider one's physical and mental well-being when undertaking such rigorous challenges.
