What do yall think about the 80/10/10 diet? (80% calories from carbs, 10% fat, 10% protein).

Hi all! I have a question, since iv been vegan iv had more energy but the last couple of days iv had little to no energy and one day two days ago I spent the whole day barely able to keep my eyes open. Iv been taking a B12 supplement and using my cpap and trying to be as active as possible. It’s also been in the 90s here so I don’t know if it’s heat exhaustion, a vitamin deficiency or what. I have been anemic in the past but not for a long time. Has anyone else experienced this? I wanted to maybe ask you guys and try to save a doctor visit.

What's everyone's thoughts on coffee/caffeine? I love my morning coffee but I'm not sure if it's serving me...

Is there a good app you all use for tracking meals, calories, nutrients; etc? Last time I was doing it we used MyFitnessPal, but that’s been a while. Bonus pics of me and the wife in Columbus, OH this weekend, eating at 4th & State Diner, a super delicious vegan restaurant downtown.

We have hit triple digits and been in the high 90's. What is everyone doing to battle the heat? Definitely do most activities in doors and drinking extra water, any other ideas?
