Feeling Very Tired After Eating On Bulletproof If
I have been doing Bulletproof IF for a week now. Prior to that I was doing keto (20-30g carbs/day) for about 2 months, and prior to that I was doing a low carb diet (50-60g carbs/day) for a month. I've never tried IF before this.
On bulletproof IF, I wake up at around 8am and have a cup of tea with 1T butter and 1T coconut oil. If I get hungry again before 2pm, I'll make another cup with the same amounts. I break the fast at 2pm, eat a regular sized LC meal, and then have a snack before 8pm which is when I start fasting again. (I should also add that since I've only been doing this for a week, I haven't done any carb ups yet. I'm actually kind of hesistant to do a carb-day at all since I have been doing so well on LC/keto without it and without any negative symptoms.)
This whole week I've been feeling mentally foggy and sort of anxious until I eat my first meal. I assume this is normal and that I'm just not fully adjusted to doing IF. Another thing that I noticed is that I've been feeling so exhausted after eating my first meal of the day. I can literally fall right asleep at 4pm without even trying.. and this sleepy feeling doesn't go away no matter what I do. I've tried upping my calories by grazing on snacks throughout the eating period. I've tried lowering my calories by eating just the one meal a day at 2pm with a snack later at night. I've tried taking the bus instead of walking my usual 4 miles each day. I've tried walking slower and not exerting myself as much. Nothing has helped get me through the day with consistent energy levels...
Is this normal? Temporary? Or is this what everyone means when they say adrenal fatigue? I've never had these symptoms on LC or keto, so I've just been assuming this is my body's way of adjusting to IF. I wasn't planning on doing carb refeeds at all because I've lost so much weight on LC/keto, and am eating the exact same way I did on keto (exclusively meats, eggs, and veggies). I never did carb 'refeeding' on keto and did not have any negative symptoms. Really the only thing that's changed between now and my keto days is the addition of bulletproof tea and my limited eating window.
