Mechanical tension refers to the force exerted on muscles during resistance training, while metabolic stress is the accumulation of byproducts, such as lactate, that occurs during exercise.
These two factors primarily drive muscle growth by signaling the body to adapt, resulting in increased muscle size and strength (1).
However, nutrition is equally important in creating an internal environment conducive to hypertrophy.
The proper nutrition for gaining muscle involves:
While protein often takes center stage in discussions about muscle gain, carbohydrates and fats are equally important for providing energy, supporting hormonal health, and optimizing performance (4, 5).
In this article, we’ll share a 7-day meal plan tailored to support muscle gain.
This plan emphasizes high-quality protein sources, balanced macronutrients, and nutrient-dense foods to help you achieve your health and wellness goals.
Eating nutrient-dense, balanced meals provides the essential fuel your body needs to perform, repair, recover, and grow.
Protein is the foundation of muscle growth.
It supplies the amino acids necessary for muscle protein synthesis, which is the process where your body repairs and builds muscle tissue after exercise (6).
Aim for a variety of high-quality protein sources to meet your needs:
Carbs are your body’s primary source of energy. They fuel your workouts, replenish glycogen stores, and help sustain your performance (4).
A mix of complex and simple carbohydrates ensures steady energy and recovery.
When it comes to weight loss, progress is made by inches, not miles, so it’s much harder to track and a lot easier to give up. The BetterMe: Health Coaching app is your personal trainer, nutritionist, and support system all in one. Start using our app to stay on track and hold yourself accountable!
Healthy fats play a crucial role in hormone production, including testosterone, which is vital for muscle growth (7).
They also offer a dense source of calories to help maintain a slight surplus for muscle gain without overeating:
Vegetables contain high amounts of vitamins, minerals, and antioxidants that support overall health and aid recovery (8).
They’re also a great source of fiber to help with digestion, especially when increasing protein intake (9).
Snacks offer an opportunity to pack in extra nutrients and calories without feeling weighed down.
They can bridge the gap between meals, keeping your energy stable throughout the day (10).
The above are only a sampling of options from each food group. Feel free to include the foods you like, are accessible to you, and within your budget for a cheap 7-day meal plan for muscle gain.

There’s no set number of meals you should eat per day to optimize lean muscle growth.
Meeting your total energy needs for the day is more critical than how many meals you spread them across. For lean muscle growth, many people may benefit from a slight calorie surplus to provide the energy their body needs for muscle repair and growth.
However, a surplus isn’t always a necessity for building muscle:
You might have heard that eating more often “stokes your metabolism” or leads to greater muscle gains. Current research, however, indicates that meal frequency itself isn’t the primary factor in determining muscle growth.
Instead, it’s about meeting your daily nutritional needs and perhaps spreading protein throughout the day to support muscle protein synthesis (12).
Most people will do well with 3-6 meals or snacks daily. The frequency you choose can depend on your preferences, lifestyle, appetite, and schedule.
Regardless of how many meals you eat, aim to include a source of protein at every eating occasion. Spacing protein intake throughout the day (every 3–5 hours) helps maintain a positive net protein balance, which is helpful for muscle repair and growth.
The current consensus from sports nutrition research suggests aiming for 1.2-2 grams of protein per kilogram of body weight per day to support muscular growth during resistance training.
For most active adults, this range ensures your body has the amino acids it needs for muscle protein synthesis, the process of building and repairing muscle tissue (13).
To put this into perspective:
Dividing your total daily protein into 3–6 evenly spaced meals or snacks—rather than loading up at a single meal—may further enhance muscle protein synthesis (12).
As a practical guide, try to include a quality protein source at each main meal, such as:
If you’re new to tracking, reading labels, and planning meals, this method can help ensure you’re hitting your target range. And remember that variety matters.
Different protein-rich foods provide other nutrients your body needs for recovery, energy, and overall well-being.
A common starting point for macronutrient distribution in a muscle gain plan is (14):
We can adjust these ratios based on individual preferences, activity levels, and metabolic needs. For example, endurance athletes or those with high training volumes may benefit from a higher carbohydrate intake.
At the same time, individuals with lower activity levels may lean toward a lower-carbohydrate, higher-fat approach.
So, what are quick meal prep ideas for a 7-day muscle plan?
You’re in the right place because this meal plan provides a balanced mix of macronutrients, high-quality protein, and nutrient-dense foods, adhering to the recommended guidelines of 45-55% carbs, 25-35% protein, and 20-35% fat.
Consider portion sizes and adjust amounts to fit your unique calorie needs for a lean muscle diet with easy meal prep.

Maintaining your satisfaction makes it easier to stick to your nutrition plan and focus on your training goals:
Including a high-quality protein source with every meal and snack helps support muscle growth and keeps you feeling full for a longer period. Protein slows digestion and may reduce the spike and dip in blood sugar that can trigger hunger (6).
Whole grains, legumes, fruits, and vegetables add bulk to meals and slow digestion. Fibre-rich choices, such as lentils, oats, berries, and leafy greens, not only promote satiety but also help stabilize appetite throughout the day (9).
Add generous portions of lower-calorie, non-starchy vegetables, like cucumbers, tomatoes, and leafy greens. These can increase meal volume, helping your stomach feel fuller for longer without a lot of extra calories (8).
Incorporate healthy fats, such as avocado, olive oil, chia seeds, or a handful of nuts, into your diet.
Fats contribute to longer-lasting fullness and enhance meal satisfaction (15).
Take time with your meals by putting down your fork between bites and paying attention to hunger and fullness cues. Mindful eating allows your body time to register satisfaction and can help reduce mindless snacking or “food noise (16).”
Sometimes, thirst can masquerade as hunger. Drink water throughout the day and consider a glass before or with meals to help with both hydration and satiety (17).
Establish a regular meal schedule to prevent becoming overly hungry or preoccupied with food. Consistency helps regulate appetite hormones and can reduce intrusive food thoughts (10).
Favour slower-digesting carbs like brown rice, sweet potatoes, and quinoa.
These help provide steady energy and a more lasting feeling of fullness than refined grains (4).
High stress and poor sleep can ramp up cravings and disrupt appetite regulation (18).
Aim to incorporate restful sleep and stress-management practices, such as deep breathing, movement, or meditation, to support balanced hunger levels.
Muscle growth, or hypertrophy, typically takes weeks to months of consistent training and proper nutrition. However, within a week, you may experience initial changes, such as improved muscle activation and glycogen storage, which can make muscles appear fuller. Signs include lack of energy, poor workout performance, no changes in muscle size or strength, and feeling excessively hungry or overly full. Adjust calorie intake, macronutrient balance, or meal timing as needed. Yes, slightly. On workout days, prioritize carbohydrates to fuel performance and recovery. On rest days, you can reduce carbs slightly and increase healthy fats if it helps to maintain energy balance. If you’re curious about a lean calisthenics body, check out our earlier article. Absolutely. Focus on plant-based protein sources, such as tofu, tempeh, lentils, quinoa, and beans. Pair these with whole grains, nuts, seeds, and dairy or plant-based protein powders to meet protein needs.Frequently Asked Questions
