Same here. I've just returned from the south of france, where we run wilderness retreats: lots of running around maintaining basecamp, daily long walks to check up on questers. Incidentally, I went on a two day fasted quest myself (our regular questers go for 4 days) Easy peasy! Cool thing was that when I returned after my retreat and upped the calories a little, I immediately had enough energy to run the afternoon shopping and cooking round. Frankly, I hadn't expected that. My mental state in the field was energetic and alert, well adjusted.

If you drop your carbs too fast, you can feel like garbage. I went from 120g to 30g over 6 weeks with no problem. I just dropped a little per week. I have gobs of energy. I have a lot more energy now than I ever did on a higher carb diet. Right now, my doctor controls my diet, so my carbs vary a lot more than I want. My daily numbers are 101g protein, 10-30g carbs per day (depending on what my doctor is requiring of me that day, and the rest is fat. I don't even track fat right now.

My diary is open, but please note I'm on a doctor-supervised diet, so portions, calories, etc. aren't what you should be doing!

The first days I was completly out of gas.

My training performance (I'm doing Freeletics, that is a High Intensity Functional Training) slowed consistently, but I insisted.

After 2 weeks, I finally experienced the first keto-boost!

Now I can tell that also HIIT training in ketosis is possible, and with good results.

I do IF either: one meal per day only (around 3Mcals) and training fasted in the morning - with tons of energies!

Something impossible with carbs.

How's your salt intake?

For me to "get over the hump" of getting into ketosis or out of low carb low energy he!!, I had to track everything. Yes, I know this sucks, but carb creep is a huge factor. 5 carbs here, 7 carbs there, adds up quickly, even though you think you're doing low carb. You're probably lower carb than ever before, but for the metabolism of some folks - 50 grams - 150 grams of carbs can be a danger zone of low energy, added cravings, and such. There is no way of pre-testing to know if that fits you or not.

So first, TRACK EVERYTHING. I did this for 6 weeks, then felt confident enough to stick with the foods I know are low-no carb.

Then, I had to get to basics. Eggs, bacon, sausage, steak, roast, chops, etc. Get rid of frilly-frou-frou stuff. Get ride of substitute recipes. For me personally, almond flour trips my insulin response just as if I'd had sugar and junk. I'm not sure why yet, but I've isolated the reaction to it. I dropped all bread and bread substitutes. Made only super simple fat bombs, etc. I ate very little "optional stuff." Lots of cheese and butter and cream cheese and sour cream. Adding in all the faux-foods and substitutes can work for some, but until you are well established, stick to lettuce leaves or cream cheese crepes for wraps, etc.

So REAL FOODS ONLY.

I know you say your wife is not on board because she doesn't believe it is healthy. My fiance is the same way, but he doesn't sabotage any of my food, luckily. I know that some people, meaning better, might sneakily push the carb limits on others. Not saying your wife is doing that, but if she really believes you are hurting yourself, she might be suffering from good intentions. Like for me, I can have half a plate of broccoli, but 1/4 cup of carrots spike my sugars. Etc.

So essentially, until you track everything, we're all playing guessing games anyway.

It really depends on what causes your high blood pressure. if you were able toncome off meds due to diet and exercise, it is unlikely that salt would affect it. but if it is genetic and underlying it might blip a bit. but continuing on plan should help level it out.

Worst case? Up salt. monitor pressure for a few days. see how you feel. Adjust from there.

It's like being a little kid again. I miss it. I hate myself right now for putting myself out of ketosis and no longer being adapted. I feel like a slug right now!
