If you can take your med, immediately, when you get up, you'd be okay to eat breakfast within 30-45 minutes.... I used to have to do this when I was working, otherwise I'd have had to get up an hour earlier than my normal 3:30 am - wasn't willing to do that...... I hopped out of bed, took my levo, then went to the kitchen to turn on the coffee pot, feed the dogs and put them outside, then go get into the shower...... by the time all of that was done, at least 30-40 minutes had gone by, coffee was done, the dogs were ready to come back in...... I'd take my coffee to the bathroom to sip while I dried my hair and got ready for work. By the time I was ready for work, an hour had gone by, so I'd eat my breakfast.... which consisted of whatever I felt like eating that day.... fiber does inhibit absorption of thyroid med, but you have to eat what you have to eat....
Maybe your dose of T4 med will have to be increased to account for what might be lost in your morning routine.
Thank you, my night time eating habits are similar in that I like a 'supper' sometimes. Currently I have my breakfast around half an hour after I get up, so maybe I need to make it an hour.
Easiest for me upon waking, wait one hr, breakfast. Thought of going to night dosing, but my eating habits change daily, sometimes I like late night snacks, such as popcorn, while watching a movie.
The rule of thumb is to take levo on an empty stomach (no food or drink for 3-4 hours prior) with a full glass of water and then refrain from any other food or drink for 0.5-1 hour after. That's why most people take it fist thing in the morning and delay breakfast a little. Coffee affects absorption as well, but not as much as some foods do, especially fiber. Any other meds or supplements should be taken 3-4 hours away from levo (if at all possible). As with different food, however, some meds affect absorption more than others, so check out interactions.
