@Stahesh @Tfmonkey Carbs does tend to make you lethargic if you eat too much of them, particularly simple carbs.

Also, high sugar consumption tends to lower testosterone in men, which leads to lack of motivation, problems handling stress, among others things, which reduces your overall energy and has a tendency to put you in a shit mood.

There is a good chance that that may be the problem or the good part of it.

Other things that lower your energy is lack of vitamin D, lack of animal fats
