I would not go crazy on oils--they are harmful in the long run. However, keeping a food journal for a while and having someone who knows what they are doing review it, would be the simplest way to go.
It is possible that in one month you simply experienced some detox from your previous diet. I deal with that a lot with people in my program. Some experience it immediately, some after a few weeks having gone vegan. Not to worry about. Going from low fiber to high fiber diet will leave you bloated sometimes, but your body will adjust. One month is not long enough to be alerted.
Do make sure to supplement with B12--some foods that have it, like yeast, are not a good source, since B12 is in its analog form and is useless. B12 costs very little and can save lives. Deficiencies are now prevalent in vegan and nonvegan populations alike. I personally developed it (although tested "normal" according to doctors) before becoming vegan. I had a lot of symptoms and could not even conceive and was diagnose with a tumor. When I got in injections, all problems went away and I got pregnant in only 4 weeks (after years of being unable to do so). So, make sure not to fall prey to the false thinking. There is more on the topic on my web-site.
So, again, I do not think that 80/10/10 diet is what is causing you not to feel energetic. I have been vegan for 7 years. I do not supplement with protein powders, I use no oils whatsoever (I do eat avocados and seeds
), I am also a fitness trainer, and NEVER had a problem with that. It might be simply detox, or something that you are missing.
I hope you are doing better by now.
