为什么我每天在健身房拼命训练，肌肉却不见长？

根据运动营养学的研究，超过80%的健身者无法达到预期效果是因为饮食问题。增肌的本质是能量溢出的过程，身体只有在摄入热量大于消耗热量（热量盈余）的情况下，才会将多余的能量用于合成肌肉。如果你练得非常辛苦但吃得不够，身体不仅不会长肌肉，反而可能因为能量不足而变得更加疲惫甚至消瘦。

科学增肌每天应该多吃多少热量？

科学的增肌建议是实现“渐进式盈余”，即每日摄入的热量比你的每日总消耗热量（TDEE）多出300到500大卡，或者增加10%到15%的摄入量。这个范围能最大限度地促进肌肉生长，同时避免因热量过剩过多而导致脂肪大量堆积。

如何计算我每天到底需要吃多少热量？

首先，你需要通过Mifflin-St Jeor公式计算基础代谢率（BMR），即维持生命所需的基本热量。男性公式为：10×体重(kg) + 6.25×身高(cm) - 5×年龄 + 5；女性则为：10×体重(kg) + 6.25×身高(cm) - 5×年龄 - 161。算出BMR后，根据你的运动强度乘以活动系数（如轻微运动为1.375，高强度运动为1.725）得到TDEE，最后在TDEE基础上增加300-500大卡即为你的增肌目标热量。

增肌期间三大营养素应该如何分配？

增肌饮食应围绕“热量盈余加蛋白质充足”展开。建议每公斤体重摄入1.6到2.2克蛋白质以支持肌肉合成；碳水化合物应占总热量的40%到50%，作为训练的能量来源；脂肪则占20%到30%，用于维持激素水平（如睾酮合成）。在实操中，可以采用少量多餐的方法，并在训练前后重点补充易消化的碳水和蛋白质。

我如何判断自己的增肌计划是否有效？

最直观的监控指标是体重的动态变化。在理想状态下，每周增重应控制在0.25到0.5公斤之间。如果每周增重超过0.5公斤，说明热量摄入过多，长的可能大多是脂肪；如果连续两周体重没有变化，则说明未达到热量盈余，需要适当增加进食量。建议每天早晨空腹称重以获得最准确的数据趋势。
