Ectomorphs tend to be linear in build and hold less size in their extremities. Overall they have a smaller skeletal structure however they may have longer arms and legs.
Their metabolic rate tends to run slightly faster. This can make fat loss a bit easier, however their appetite can increase quickly with activity making them susceptible to energy crashes if they don’t get enough fuel. Adequate protein and regular meal timing is important for Ectomorphs.
Gaining muscular size can be harder for Ectomorphs but progress is usually noticeable when they include strength training since less body fat in their extremities makes the muscle more visible.
Ectomorphs acclimate the quickest of the three body types to increased food intake, which can help with fat loss, but creates challenges when trying to gain weight. If weight loss is the goal, Ectomorphs usually respond well to calculated “up-adjusting” (periods of increased fuel) when part of a bigger fat loss strategy.
If building muscle is the goal, it’s very important not to miss meals!
