💪 Bulking Diet Guide — How to Eat for Muscle Gain💪 健身增肌期怎么吃？增肌饮食指南

Core Principles of Bulking增肌的核心原则

Bulking is not about "getting fat." It is about providing your body with enough energy and raw materials to repair and grow muscle after training. Three pillars work together — none can be skipped:增肌的本质不是「吃胖」，而是给身体提供足够的能量和原料，让肌肉在训练破坏后有修复和超量恢复的能力。三个核心支柱缺一不可：

1. Progressive overload: Continuously challenge your muscles with heavier weights, more sets, or more reps — this is the "signal" for growth.渐进超负荷训练：不断给肌肉更大的刺激（加重、加组、加次数），这是肌肉生长的「信号」。
2. Calorie surplus: Consume more energy than you burn to fuel muscle protein synthesis.热量盈余：摄入大于消耗，为肌肉合成提供额外能量。
3. Adequate protein: The "building material" for muscle — without enough protein, there is no muscle growth.充足的蛋白质：肌肉的「建筑材料」，没有蛋白质就没有肌肉生长。

Missing any one of these three legs will significantly compromise your results. Many people train hard yet see little muscle gain — the problem is almost always in their diet: not eating enough, or not eating the right things.三条腿缺一条，增肌效果都会打折扣。很多人练得很苦却不见长肌肉，问题往往出在饮食上——吃不够、或者没吃对。

Calorie Surplus: How Much Is Right?热量盈余：多大才合适？

Bulking requires a calorie surplus, but this does not mean you can eat everything in sight. Too large a surplus will only add excess fat that you will need to lose later during the cutting phase.增肌需要热量盈余，但这不意味着可以放开吃。过大的盈余只会让你长更多脂肪，减脂期要花更多功夫去减掉它们。

Recommended Surplus: 200~400 kcal/day推荐盈余范围：200~400 大卡/天

This range supports muscle protein synthesis without excessive fat gain. The specific number depends on your experience level:这个范围既能支持肌肉蛋白质的合成，又不会囤积过多脂肪。具体选择看你的基础和训练经验：

• Beginner (under 1 year): 200~300 kcal surplus is sufficient. Newbie gains mean your body responds well without needing a large surplus.新手（训练 1 年内）：盈余 200~300 大卡即可。新手福利期身体对训练反应灵敏，不需要太多盈余。
• Intermediate (1~3 years): 300~400 kcal surplus. As training age increases, muscle gain gets harder and requires more energy support.中级（训练 1~3 年）：盈余 300~400 大卡。随着训练年限增长，增肌越来越难，需要更多能量支持。
• Hardgainer (naturally skinny): Can go up to 400~500 kcal. These individuals have very high metabolisms and rarely store fat.偏瘦型体质：可以适当增加到 400~500 大卡。这类人代谢极高，不易囤脂肪。

How to calculate? First, find your BMR and TDEE, then add the surplus:怎么计算？先算你的 BMR 和 TDEE，然后加上盈余：

Bulking intake = TDEE + 200~400 kcal增肌摄入 = TDEE + 200~400 大卡

A 70kg (154 lbs) person training 4 days per week has a TDEE of approximately 70 × 33 ≈ 2310 kcal. During bulking, they should eat 2500~2700 kcal per day.一个 70kg、每周训练 4 天的人，TDEE ≈ 70×33 ≈ 2310 大卡，增肌期可以吃 2500~2700 大卡。

Protein: The #1 Nutrient for Muscle蛋白质：增肌的头号营养

Protein is the fundamental building block of muscle. Muscle protein synthesis (MPS) and muscle protein breakdown (MPB) exist in dynamic equilibrium — bulking means tipping the balance toward synthesis.蛋白质是肌肉合成的基础原料。肌肉蛋白质的合成（MPS）和分解（MPB）处于动态平衡中，增肌就是要让合成 > 分解。

How Much Protein Per Day?每天该吃多少？

The recommendation for bulking is 1.6~2.2g of protein per kg of body weight. A 70kg person needs 112~154g of protein daily.增肌期推荐每公斤体重 1.6~2.2g 蛋白质。70kg 的人每天需要 112~154g 蛋白质。

Breaking down the range:关于这个范围：

• Minimum 1.6g/kg: Sufficient for most people to support muscle gain. 70kg = 112g/day.最低线 1.6g/kg：对于大多数人已经足够支持增肌。70kg = 112g/天。
• Recommended 2.0g/kg: Ideal for most fitness enthusiasts. 70kg = 140g/day.推荐线 2.0g/kg：适合大部分健身爱好者。70kg = 140g/天。
• Upper limit 2.2g/kg: Useful during cutting phases or for advanced lifters. Beyond this, extra protein provides diminishing returns.上限 2.2g/kg：减脂期或高阶训练者可能需要更多。超过这个量对增肌的额外帮助已经很小。

Distribution Across Meals Matters More每餐分配更关键

Research shows that consuming 30~45g of protein per meal (about 0.4g/kg/meal) maximizes the muscle protein synthesis response. Instead of concentrating all your protein in one or two meals, spread it evenly across 3~4 meals:研究表明，每餐摄入 30~45g 蛋白质（约 0.4g/kg/餐）对肌肉合成的刺激最大。把所有蛋白质集中在一两餐吃，不如平均分配到 3~4 餐：

• Breakfast: 30g protein (e.g., 3 eggs + 200ml milk)早餐：30g 蛋白质（如 3 个鸡蛋 + 200ml 牛奶）
• Lunch: 40g protein (e.g., 150g chicken breast)午餐：40g 蛋白质（如 150g 鸡胸肉）
• Post-workout: 35g protein (e.g., 1.5 scoops whey protein)训练后：35g 蛋白质（如 1.5 勺蛋白粉）
• Dinner: 40g protein (e.g., 150g fish or beef)晚餐：40g 蛋白质（如 150g 鱼肉或牛肉）

That adds up to 145g, meeting the needs of a 70kg individual.这样一算已有 145g，达到 70kg 人的需求线。

Recommended Protein Sources蛋白质来源推荐

• Animal protein: Chicken breast, skinless chicken thighs, lean beef, eggs, milk, salmon, shrimp, Greek yogurt动物蛋白：鸡胸肉、去皮鸡腿、瘦牛肉、鸡蛋、牛奶、三文鱼、虾、希腊酸奶
• Plant protein: Tofu, edamame, chickpeas, quinoa植物蛋白：豆腐、毛豆、鹰嘴豆、藜麦
• Supplements: Whey protein (post-workout), casein (slow-release before bed)补剂：乳清蛋白粉（训练后）、酪蛋白（睡前缓释吸收）

Carbs and Fats: Their Roles碳水和脂肪的角色

Carbs — Fuel for Muscle Growth碳水 — 增肌的燃料

Carbohydrates play two key roles in bulking:碳水在增肌中起两个关键作用：

1. Provide training energy: Muscle glycogen is your primary fuel for weight training. Low glycogen severely compromises workout performance.提供训练能量：肌肉中的糖原是你做重量训练的燃料，低糖原状态下训练效果大打折扣。
2. Stimulate muscle synthesis: Carbs stimulate insulin secretion, which acts as a "switch" that signals muscle cells to absorb amino acids and build protein.促进肌肉合成：碳水刺激胰岛素分泌，胰岛素是促进肌肉细胞吸收氨基酸和合成蛋白质的「开关」。

Recommended intake: 4~6g of carbs per kg of body weight. 70kg = 280~420g/day.推荐摄入量：每公斤体重 4~6g 碳水。70kg = 280~420g/天。

High-quality carb sources: Oats, brown rice, sweet potatoes, whole wheat bread, quinoa, fruits, potatoes.优质碳水源：燕麦、糙米、红薯、全麦面包、藜麦、水果、土豆。

Fats — Hormone Regulators脂肪 — 稳激素

Insufficient fat intake can impair the production of anabolic hormones like testosterone, which are crucial for muscle growth. Fats should make up 20%~30% of total calories, at minimum 0.8g/kg/day.脂肪摄入不足会影响睾酮等合成激素的分泌，这正是增肌需要的关键激素。推荐占总热量的 20%~30%，最低不低于 0.8g/kg/天。

Quality fat sources: Olive oil, avocado, nuts, egg yolks, salmon, flaxseed oil.优质脂肪来源：橄榄油、牛油果、坚果、蛋黄、三文鱼、亚麻籽油。

Pre & Post Workout Nutrition训练前后怎么吃？

Pre-Workout (1~2 hours before)训练前（1~2 小时）

Goal: Fuel your training session and maximize performance.目标：补充能量、保证训练表现。

• Carbs: 30~50g of low-GI carbs (e.g., a banana + 2 slices whole wheat bread) for sustained energy.碳水：30~50g 低 GI 碳水（如一根香蕉 + 两片全麦面包），提供稳定能量。
• Protein: 15~25g (e.g., a glass of milk or a small scoop of protein powder) to boost amino acid availability during training.蛋白质：15~25g（如一杯牛奶或一小勺蛋白粉），提高训练中氨基酸供应。
• Low fat, low fiber: Avoid digestive discomfort during your workout.低脂肪、低纤维：避免训练中出现消化不适。

Sample pre-workout snack (1 hr before): 1 banana + 1 tbsp peanut butter + 1 slice whole wheat toast ≈ 300 kcal.训练前 1 小时加餐示例：香蕉 1 根 + 花生酱 1 勺 + 全麦吐司 1 片 ≈ 300 大卡。

Post-Workout (within 30~60 minutes)训练后（30~60 分钟内）

Goal: Rapidly replenish glycogen stores and kickstart muscle repair. The "anabolic window" is not as narrow as once thought (30 minutes), but timely post-workout nutrition does improve recovery efficiency.目标：快速补充糖原、启动肌肉修复。训练后是「营养窗口期」，虽然这个窗口不像过去说的那么窄（30 分钟），但训练后及时补充确实能提高恢复效率。

• Carbs: 30~60g of medium-to-high GI carbs (white rice, potatoes, banana, dextrose) for rapid glycogen replenishment.碳水：30~60g 中高 GI 碳水（如白米饭、土豆、香蕉、葡萄糖），快速补糖。
• Protein: 25~40g (whey protein is fast-absorbing and ideal post-workout) to rapidly initiate muscle synthesis.蛋白质：25~40g（乳清蛋白吸收快，是训练后的首选），快速启动肌肉合成。

Sample post-workout snack: 1.5 scoops protein powder + 1 banana + 200ml milk ≈ 400 kcal, or a bowl of rice + 150g chicken breast.训练后加餐示例：蛋白粉 1.5 勺 + 香蕉 1 根 + 牛奶 200ml ≈ 400 大卡，或者一碗米饭 + 150g 鸡胸肉。

Supplements for Bulking增肌粉与补剂

Remember: supplements are meant to supplement, not replace real food. Get your diet right first before considering supplements.补剂的作用是「补充」，而不是「替代」。先把三餐吃好了再谈补剂。

Recommended Supplements推荐使用的补剂

• Whey protein: The most practical supplement. 1~2 scoops post-workout for fast protein. Convenient, fast-absorbing, and cost-effective.乳清蛋白粉：最实用的补剂，训练后 1~2 勺快速补充蛋白质。方便、吸收快、性价比高。
• Creatine monohydrate: The most scientifically supported strength supplement. Can improve strength by 5%~15%, helps muscles hold water (making them look fuller), and is completely safe.肌酸（一水肌酸）：最有科学依据的力量类补剂，能提升力量 5%~15%，帮助肌肉储水（让肌肉看起来更饱满），完全安全。
• Caffeine: 200~400mg pre-workout to boost energy and focus. Not essential but useful.咖啡因：训练前 200~400mg 提升能量和专注度，不是必须但有用。

What About Mass Gainers?什么是增肌粉（Mass Gainer）？

Mass gainer = protein powder + lots of carbs (maltodextrin, etc.) + a small amount of fat. One serving typically provides 500~1000 kcal. Who should use it?增肌粉 = 蛋白粉 + 大量碳水（麦芽糊精等）+ 少量脂肪。一份增肌粉通常 500~1000 大卡。它适合什么人群呢？

• Suitable for: Extremely skinny individuals who struggle to gain weight; busy people with no time to prepare meals.适合：极度偏瘦、怎么吃都长不胖的人；每天工作忙没时间做饭的人。
• Not suitable for: Most people. Mass gainers often use low-quality carb sources (maltodextrin has a very high GI), and they are less cost-effective than making your own "protein + oats + peanut butter" combo.不适合：大多数人。一方面增肌粉的碳水来源品质不高（麦芽糊精 GI 极高），另一方面性价比不如自己用「蛋白粉 + 燕麦 + 花生酱」组合。

Supplements we do NOT recommend: BCAAs (branched-chain amino acids — just eat more protein), testosterone boosters (mostly ineffective or contain banned substances), fat burners (fat loss comes from a calorie deficit, not a bottle).不推荐的各种补剂：BCAA（不如直接吃蛋白粉）、睾酮促进剂（基本无效或含违禁成分）、脂肪燃烧剂（减脂靠热量缺口，不靠瓶子）。

Common Bulking Mistakes常见误区

❌ Mistake 1: Eating everything in sight during bulking❌ 误区 1：增肌期可以胡吃海塞

"Bulking means eating anything" is the oldest myth. An excessive surplus (500+ kcal/day) won't build more muscle — it will only add more fat. The extra fat becomes a burden during cutting cycles. Lean bulking is the better long-term strategy.「增肌就是吃」是最老的误区。过大的热量盈余（500+ 大卡/天）不会让你多长肌肉，只会堆更多脂肪。干净增肌（Lean Bulk）才是长期策略。

❌ Mistake 2: Only focusing on protein, ignoring carbs and fats❌ 误区 2：只在乎蛋白质，不管碳水和脂肪

Protein is the raw material, but carbs provide the "construction crew's fuel" and fats keep the "project management office" running. Each macronutrient plays an essential role.蛋白质是原料，但碳水提供「施工队的燃料」，脂肪维持「项目指挥部的正常运转」。三大营养素各有角色，缺一不可。

❌ Mistake 3: Must drink protein immediately after training❌ 误区 3：训练后必须马上喝蛋白粉

Post-workout nutrition is helpful but the "30-minute golden window" is overblown. If you ate a proper meal before training, eating 1~2 hours after is fine. What matters more is your total daily protein intake.训练后及时补充确实有帮助，但不是什么「30 分钟黄金窗口」。如果训练前已经吃了正常的一餐，训练后 1~2 小时再吃也没问题。更重要的是全天的总蛋白质摄入量是否足够。

❌ Mistake 4: High protein damages kidneys❌ 误区 4：蛋白粉吃多了伤肾

For healthy individuals, high protein intake (up to 2.5g/kg) does NOT damage the kidneys. Only people with existing kidney disease need to restrict protein. If your kidneys are healthy, eat your protein and drink plenty of water.对于 健康人，高蛋白饮食（直到 2.5g/kg）不会对肾脏造成伤害。肾脏疾病患者才需要控制蛋白质。如果你肾功能正常，放心吃，多喝水就行了。

❌ Mistake 5: Can't eat before bed❌ 误区 5：睡前不能吃东西

Eating before bed during bulking is actually beneficial! Casein protein (found in cottage cheese, Greek yogurt) digests slowly and provides a steady stream of amino acids to your muscles throughout the night. Enjoy 200g of Greek yogurt or a casein shake 1 hour before bed.增肌期睡前吃一顿是有益的！酪蛋白（如茅屋芝士、希腊酸奶）消化缓慢，可以在睡眠中持续给肌肉提供氨基酸。睡前 1 小时吃 200g 希腊酸奶或喝一杯酪蛋白粉，对增肌有帮助。

Summary: Bulking is not about eating recklessly — it is about precise calorie control and intelligent macronutrient distribution. Calculate your TDEE, set a modest 200~400 kcal surplus, hit your protein targets, and distribute it evenly across meals and around your training sessions. Combine this with a solid training program, and muscle will grow — but be patient, because muscle gain is slower than fat loss (gaining 0.5~1kg of lean muscle per month is already excellent). Stick with it for six months, and you will see dramatic changes.总结：增肌不是靠蛮吃，而是靠精准的热量控制和对的营养素分配。算清楚你的 TDEE，设置 200~400 大卡的温和盈余，吃够蛋白质并把它们均匀分配在三餐和训练前后。配合科学的训练计划，肌肉自然会长出来——只是需要耐心，因为肌肉生长比减脂慢得多（一个月能长 0.5~1kg 纯肌肉已经非常不错了）。坚持半年，你会看到显著的变化。
