Yoga and meditation are very helpful achieving balance yes. I am still learning about nutrition, in terms of ratios of fats, proteins and carbohydrates - there are some Doctors who completely contradict what others say and give detailed scientific reasons as to why, for example, a high fat diet is just fine. I'm not sure I like the idea of a high fat diet, so for now I am just sticking to plant based nutrition and it is working well for me.
