Muscle gain
Muscle gain diet plans
Building muscle needs three things from nutrition: enough total calories, enough protein, and enough carbohydrate to train hard. SmartyDiet calculates all three for your body and builds the meals.
The calorie surplus that builds muscle, not just weight
Start from your maintenance calories (BMR × activity factor) and add roughly 10%. For a 78 kg man training four times a week with a TDEE near 2,850 kcal, that is about 3,100 kcal per day. Track the scale weekly: gaining 0.25-0.5% of body weight per week keeps the ratio of muscle to fat favourable. If the scale climbs faster, trim the surplus rather than adding cardio.
Protein: how much, and how to spread it
Aim for 1.6-2.2 g per kilogram per day, divided into 3-5 servings of 25-40 g each. Distribution matters because muscle protein synthesis responds to each protein feeding rather than to a single large dose.
- Breakfast: eggs, Greek yogurt, cottage cheese, milk, oats with whey or soy milk
- Lunch and dinner: chicken breast, lean beef steak, turkey, salmon, tuna, white fish, tofu, tempeh, seitan
- Plant-based combinations: lentils and rice, chickpeas and couscous, beans and corn
- Evening: a slow-digesting protein such as cottage cheese or casein-rich dairy
Carbohydrates fuel the training that causes growth
Carbohydrate refills muscle glycogen, supports training volume and blunts muscle breakdown. Active lifters typically do well on 4-6 g per kilogram per day, concentrated in the meals before and after training. Rice, oats, potatoes, pasta, whole-grain bread, fruit and legumes are the practical staples.
Fats, micronutrients and recovery
Keep fats at 0.6-1.0 g per kilogram from olive oil, nuts, seeds, avocado and fatty fish. Do not cut them to make room for more carbohydrate — testosterone and vitamin absorption depend on adequate fat. Sleep, progressive overload and consistent training remain the actual growth stimulus; nutrition permits growth, it does not cause it.
Body recomposition instead of bulking
Beginners, people returning after a break and those carrying extra body fat can add muscle at maintenance calories with very high protein. SmartyDiet supports this as a distinct goal: the calories stay level, protein goes to the upper end of the range, and carbohydrates are timed around training.
Frequently asked questions
What is a calorie surplus?
A calorie surplus means eating more calories than you burn, giving the body the raw material to build new tissue. For muscle gain a surplus of roughly 5-15% above maintenance — often 200-400 kcal per day — is enough. Larger surpluses mostly add fat.
What should I eat to build muscle?
Anchor every meal with 25-40 g of high-quality protein, add carbohydrates around training to fuel and refuel sessions, and keep fats at 0.6-1.0 g per kilogram for hormonal health. Eggs, chicken, beef, fish, dairy, tofu, tempeh and legumes with rice, oats, potatoes and fruit cover almost everything.
How much protein do I need to gain muscle?
About 1.6-2.2 g per kilogram of body weight per day. Intakes above that have not been shown to add muscle faster in trained lifters eating enough total calories.
How fast can I gain muscle?
Realistically 0.25-0.5% of body weight per week for beginners, and slower for experienced lifters. Faster weight gain than that is mostly fat and water.
Do I need to eat protein immediately after training?
The so-called anabolic window is much wider than once believed. Total daily protein and a sensible distribution across 3-5 meals matter far more than eating within 30 minutes of finishing a session.
