健身饮食：碳水化合物的混乱认知原则
摘要
AthleanX 的 Jeff Cavalere 认为，回避碳水化合物是运动员和健身爱好者在营养方面所犯的最大错误之一。他解释说，complex carbohydrates 对于维持能量、保持 muscle glycogen（肌糖原）以及最大化健身房表现至关重要。他以自己的一餐为例，概述了一个简单的餐盘构建框架，每餐均应包含淀粉类碳水化合物、膳食纤维类碳水化合物、蛋白质和健康脂肪。
核心要点
- 回避碳水化合物适得其反 — 对于任何想要增肌或提升运动表现的人来说，完全摒弃碳水化合物被描述为营养方面的”大忌”之一。
- 碳水化合物调节血糖并为训练提供燃料 — complex carbohydrates 有助于全天维持稳定的 blood sugar levels（血糖水平），并保持 muscle glycogen（肌糖原）储量充足，这直接支撑训练强度和肌肉饱满度。
- Ketogenic diets（生酮饮食）并非长期解决方案 — 遵循以脂肪为主的饮食方式（如 Atkins 饮食法）会迫使身体产生 ketones（酮体）。Jeff 认为酮体是效率较低的能量来源，会让你在健身房感到精力耗竭、表现下降。
- 餐盘框架 — 每餐应围绕四个组成部分来构建：
- 淀粉类碳水化合物（如红薯、古斯米）— 约占餐盘的一半
- 膳食纤维类碳水化合物（如毛豆、西兰花、菠菜）— 约占餐盘的三分之一
- 蛋白质来源（如鸡肉）— 每餐必备
- 健康脂肪（如鹰嘴豆泥）— 被描述为”附带脂肪”，每餐适量添加
- 肌肉扁平是碳水化合物摄入不足的信号 — 长期回避碳水化合物会导致肌肉看起来扁平、感觉无力，无论训练多么努力都无法改变。
- 份量因人而异，食物选择普遍适用 — 体重 170 磅和 220 磅的人所需的食物数量不同，但食物种类和餐食结构对所有人而言应保持一致。
- 无需计算卡路里 — 该方法强调灵活性，以食物组成为基础，而非精确测量，使其对大多数人来说更具可持续性和实用性。

BodyBuilder Diet: The Carb Confusion Principle
Summary
Jeff Cavalere of AthleanX argues that avoiding carbohydrates is one of the biggest nutritional mistakes athletes and gym-goers make. He explains that complex carbohydrates are essential for sustaining energy, maintaining muscle glycogen, and maximizing performance in the gym. Using his own meal as an example, he outlines a simple plate-building framework that includes starchy carbs, fibrous carbs, protein, and healthy fats at every meal.
Key Points
- Carb avoidance is counterproductive — Cutting out carbohydrates is described as one of the “cardinal sins” of nutrition for anyone trying to build muscle or perform athletically.
- Carbohydrates regulate blood sugar and fuel workouts — complex carbohydrates help maintain stable blood sugar levels throughout the day and keep muscle glycogen stores full, which directly supports training intensity and muscle fullness.
- Ketogenic diets are not a long-term solution — Following a fat-dominant approach like Atkins forces the body to produce ketones, which Jeff argues are less efficient energy sources that leave you drained and underperforming in the gym.
- The plate framework — Every meal should be built around four components:
- Starchy carbohydrates (e.g., sweet potatoes, couscous) — roughly half the plate
- Fibrous carbohydrates (e.g., edamame, broccoli, spinach) — roughly one third of the plate
- Protein source (e.g., chicken) — present at every meal
- Healthy fats (e.g., hummus) — described as “incidental fat,” a modest addition to each meal
- Muscle flatness is a sign of carb deprivation — Consistently avoiding carbs will cause muscles to appear flat and feel weaker, regardless of training effort.
- Portion sizes are individual, food choices are universal — A 170 lb person and a 220 lb person will need different quantities, but the types of food and the meal structure should remain the same across individuals.
- No calorie counting required — The approach emphasized is flexible and component-based rather than precise measurement, making it more sustainable and practical for most people.
