What if I always feel full and have a hard time gaining weight?

Have you ever heard the term ectomorph?
It's a big word, but has a very simple definition - an ectomorph refers to the body type that's naturally smaller and leaner.
As an ectomorph, you have a fast metabolism, so it's harder for you to gain size and eat enough to put on muscle. It can feel like you're constantly eating and eating and eating without any real effects on weight gain.

Is that you?

Don't worry - I have a very simple solution for you!
Ready?
Eat calorically dense foods!
Let's take a look at an example:

One cup of spinach, has 7 calories, while one cup of peanut butter has a whopping 1,500 calories! See the difference here?
So, as an ectomorph, your should try to find foods that have very a lot of calories in very little volume. Foods that "pack a bunch."
This will allow you to not feel like your constantly stuffing your face AND finally gain muscle!!

The key here is to keep eating healthy - not to eat a bunch of ice cream and call it a day.

So what are some calorically dense foods that are healthy and easy to eat?
Think fat!

Fat has 9 calories per gram (in comparison with 4 calories per gram of protein and carb).

So add some healthy (unsaturated) fats to your diet by simply sprinkling a tablespoon or two on meals!
My favorite healthy fats are:

Oils: Olive, Fish (Omega-3), Avocado, Peanut, Flaxseed, and Sunflower Seed

Nut Butters: Almond, Macadamia Nut, Peanut, Cashew, and Hazelnut
