Congratulations on your successful weight/fat loss. The symptoms you describe result from not yet being fat adapted in the sense that your muscles and other organs are still learning how to utilize fatty acids and ketones efficiently. Yes, even after 8 months! Your addition of enhanced exercise puts a heavier load on everything and the results are what you describe. My recommendation is just tough it out - it will pass eventually. If you start eating carbs to alleviate the symptoms they may in fact go away, but so will your opportunity to get fully fat adapted. You will also lose the health benefits of remaining consistently in ketosis. Yes, you can maintain keto forever. For 3+ million years, our ancestors spent probably 90% or more of their lives in ketosis. We have evolved to live in ketosis - itās our natural and healthy metabolic state.
As for macros, I agree with @Shortstuff you may simply just need to eat more overall and bump up your protein. Youāve added exercise to your daily routine which requires more overall energy than before - āeat less move moreā only works short term before you drop from exhaustion. In fact, it sounds like thatās what youāre going through now. Did you lower overall calories during the past several months thinking you had to āeat less move moreā? In addition, when exercising vigorously your muscles need more protein to maintain and strengthen, otherwise they just give up. More protein will also help stop your hair loss. Donāt fear protein, it doesnāt automagically turn into glucose just because you ate a gram or two more than absolutely required.
I think Bikmanās recommendation of 1-2 grams of protein per kilogram of total body weight is the easiest way to calculate macros if youāre not either very large or very small. Iād suggest you start at 1.5 grams and adjust over time as needed. Then by trial and error determine the total energy intake required to maintain stable weight at your new exercise-enhanced level. This may take a few months so be patient. Likely, you will eventually determine a āwindowā of total intake of +/- 3-400 calories or so within which you will comfortably maintain. (Example: my caloric maintenance window is 2300-2700 calories per day - Iām a moderately active 76 year old male, total weight 145 pounds, BF 14-15%) You will also likely find that you end up with a macro somewhere around 1.5:1 fat grams:protein grams.
Hope this helps.
PS: About the āmaintenance windowā. If I eat consistently at the upper end of my window, I will eventually (2-3 weeks) start to gain weight. If I eat consistently at the lower end of my window, I will eventually start to lose weight. Thatās what I mean by calling it a āmaintenance windowā. I use it, too, for example: if I want to drink some alcoholic beverage I eat at the low end of my window for a few days before and after, since Iām going to get energy/fat from the alcohol and need to allow for that. If I do some IF for a few days, then Iāll eat to the upper end of my window for a few days afterwards to avoid losing weight.
) but I am starting to jog and do workout tapes. I noticed I get extremely exhausted and dizzy and lately i have been feeling quite strange after workout (Iām also tired of my hair falling out 
) and Iām thinking itās time to slowly transition to low carb as I know I cannot do keto forever. Anyways if anyone is able to help me out with the carb/fat/protein ratio would be much appreciated im wearing myself out over here stressing about this lol
Protein turning into glucose just because you eat high protein is an old myth, itās not like that.
