What You'll Learn

Caloric deficit or surplus
Rest days are important for muscle recovery and growth, and your nutritional choices on these days are crucial. While you may not need as many calories on rest days compared to high-activity days, it is still important to fuel your body adequately. Significantly reducing calories on rest days can hinder muscle growth and recovery, as your body needs the energy to repair and prepare for the next training session.
It is recommended to keep your calorie intake relatively consistent on both training and rest days and to pay attention to your body's hunger cues. You can do this by journaling and logging your food intake and how it makes you feel. It is not uncommon to feel hungrier on rest days, as your body is telling you it needs fuel to recover.
On rest days, focus on nutrient-rich foods that promote recovery, such as protein, complex carbohydrates, and healthy fats. Protein is essential for muscle repair and growth, as it provides the amino acids your body needs to build new tissue. Aim for 20-30g of protein every 2-4 hours throughout the day. Good sources of protein include chicken, fish, lean meat, eggs, cottage cheese, and Greek yogurt.
In addition to protein, include complex carbohydrates in your rest day meals. Carbohydrates are stored as glycogen in your muscles and liver and are depleted during exercise. Examples of complex carbs include fruits, vegetables, and whole grains like quinoa, brown rice, and whole wheat bread.
Healthy fats should also be a part of your rest day nutrition. Healthy fats can help reduce inflammation caused by training and are found in foods like avocados, nuts, olive oil, and oily fish.
Lastly, staying hydrated is crucial on rest days. Your body is mostly made of water, and staying hydrated helps prevent muscle cramps and ensures proper nutrient transmission. It is recommended to drink at least 2 liters of water per day and more if you are losing fluids through sweat.

Muscle repair and growth
Rest days are an important part of muscle repair and growth. After exercising a specific muscle group, it is recommended to let it rest for one to two days. This gives your muscles a chance to repair and heal. During exercise, microscopic tears occur in the muscle tissue, and during rest, cells called fibroblasts repair this damage, resulting in stronger muscles and increased muscle mass.
To support muscle repair and growth on rest days, it is important to consume adequate protein and carbohydrates. Protein supports muscle protein synthesis by supplying amino acids that help heal recovering muscle tissue. It is recommended to consume 25-40 grams of protein every 3-4 hours to stay in a positive protein balance and stimulate muscle growth. Good sources of protein include animal-based products such as dairy, eggs, turkey bacon, chicken, beef, and fish.
In addition to protein, carbohydrates are important for muscle recovery. Carbohydrates help restore glycogen levels, which are broken down during exercise to fuel your workout. On rest days, you don't need as many carbohydrates as on active days, but it is still important to include them in your diet. A 1:1 ratio of protein to carbohydrates is recommended to minimize carbohydrate intake while still supporting muscle growth.
Vitamin D is another key nutrient for muscle recovery and growth. It has been shown to benefit muscle function and aid in reducing exercise-induced inflammation. Including vitamin D-rich foods such as eggs, mushrooms, sardines, and milk in your diet can support muscle recovery.
Finally, getting enough sleep is crucial for muscle repair and growth. Sleep plays a vital role in cellular repair, regeneration, and hormone regulation, all of which are important for muscle building. Growth hormones are highest when we sleep, further emphasizing the importance of adequate rest for muscle recovery and growth.

Nutrient-rich foods
Protein-rich foods are particularly important on rest days as they provide the amino acids needed to repair and build new lean tissue. Good sources of protein include chicken, beef, fish, eggs, cottage cheese, Greek yogurt, turkey, and dairy products. Plant-based sources of protein include tofu, tempeh, legumes (beans, peas, and lentils), nuts, and seeds. Aim to include a protein-containing food at each meal and snack, with protein making up at least a quarter of your plate.
In addition to protein, complex carbohydrates are also important on rest days. Carbohydrates are stored as glycogen in the muscles and liver and are depleted during exercise. Focus on choosing complex carbs such as fruits, vegetables, and whole grains like quinoa, brown rice, and 100% whole wheat pasta or bread. The International Society of Sports Nutrition recommends athletes aim for a 3:1 or 2:1 carbohydrate to protein ratio during recovery, depending on the intensity of their workouts.
Antioxidant-rich foods are also beneficial on rest days as they help to reduce inflammation that can occur after intense workouts. Fill your plate with dark-colored produce like beets, berries, and leafy greens, as well as other fruits and vegetables to boost your antioxidant intake. Staying hydrated is also key, as water helps prevent muscle cramps and transmits nutrients throughout your body. Aim for at least half your body weight in ounces of water per day.
While it may be tempting to treat rest days as "cheat days," filling up on junk food can leave you feeling fatigued and dehydrated. Instead, focus on choosing nutrient-dense foods that will support your body's recovery and help you return to your workouts feeling stronger and well-rested.

Alcohol consumption
Impact on Workout Recovery and Performance
Alcohol can hinder muscle recovery and performance. When you consume alcohol, your body prioritizes processing it over repairing muscles, potentially wasting the efforts of your workout. Additionally, alcohol disrupts sleep patterns, affecting your REM cycle and resulting in groggy mornings, which can further hinder your gym performance. Therefore, it is advisable to avoid drinking heavily before an intense workout day.
Recommendations for Rest Days
Some individuals prefer to schedule their rest days to coincide with days when they anticipate being hungover. This strategy ensures that the negative impact of alcohol consumption on sleep and recovery primarily occurs on a day without intense physical activity. However, it is essential to maintain proper nutrition even on rest days. Alcohol provides empty calories, and drinking can lead to poor diet decisions, such as craving saltier snacks due to dehydration.
Strategies for Reducing Alcohol Intake
If you aim to reduce your alcohol consumption, several strategies can help. Firstly, you can opt for lower-alcohol beverages, such as lighter beers (under 4% ABV) or choose no- or low-alcohol alternatives. Additionally, spreading your drinking over several days and incorporating drink-free days into your week can help lower your overall consumption. It is also beneficial to track your units or utilize apps like the NHS Drink Free Days app to monitor your intake and set weekly targets.
Health Benefits of Reducing Alcohol Intake
Taking a break from alcohol or reducing your intake can lead to various health benefits. You may experience improved sleep, increased energy, and weight loss. Additionally, you could notice positive changes in your relationships and finances. Most importantly, lowering your alcohol consumption reduces your risk of serious health issues, including liver disease, high blood pressure, and certain types of cancer.
In conclusion, while enjoying an occasional drink on a rest day is not necessarily detrimental, excessive alcohol consumption can hinder your fitness progress and negatively impact your health. Finding a balance between social enjoyment and a healthy lifestyle is essential. If you struggle with alcohol dependence, it is crucial to seek professional help to support you in reducing or stopping your alcohol intake.

Carbohydrates and protein
On rest days, it is important to consume adequate amounts of carbohydrates and protein to support muscle recovery and growth. While the body doesn't require as many carbohydrates on rest days compared to active days, they still play a vital role in providing energy and ensuring that protein can be used for its essential functions. Carbohydrates are stored as glycogen in the muscles and liver, which can be broken down during sleep and exercise to maintain blood sugar levels. Therefore, including some carbohydrates on rest days is recommended.
Protein, being the building block of muscles, is essential to consume on rest days to support muscle repair and growth. Research suggests consuming 25-30 grams of protein every 3-4 hours to stimulate muscle protein synthesis effectively. This can be achieved through whole food sources such as chicken, beef, fish, tofu, legumes, nuts, and seeds, or through protein powders and shakes.
It is worth noting that significantly reducing calories on rest days can hinder muscle growth and recovery. Instead, focus on choosing nutrient-dense foods that support muscle recovery and promote hydration, such as fruits and vegetables, which are high in antioxidants and help reduce inflammation.
Additionally, vitamin D-rich foods on rest days can enhance recovery and lean mass maintenance. Examples of vitamin D-rich foods include salmon, herring, sardines, eggs, and fortified milk. Overall, a balanced approach to nutrition on rest days, including adequate carbohydrate and protein intake, is recommended to support optimal muscle function and recovery.
