Summary:
SLGS you reduce anytime under 90 (exception being back to back reductions, have to let depot drain first). But you hold the dose for a week, then do a curve. Technically the required tests are only the preshots, and the curve once a week. Based on the curve you can decide to hold/increase/decrease. For some people, this works best for their schedule, sleep, health, etc. The downside is you end up holding doses fairly long, so some glucose toxicity can set in and/or it takes longer to get regulated. Lower chances of remission.
TR you reduce under 50, also must be completely low carb wet diet. 4 tests minimum - the two preshots, plus one more test each cycle. Those extra tests should be strategic to get the whole picture over the course of a few days. Increases can be done every 3-5 days depending on nadir. Benefits are better numbers more quickly, better chances at remission. Downside is the testing...those 4 are the minimum. As they get into lower number it can be more testing, less sleep. That same can be true of SLGS but it generally keeps them in the 90-150 range when regulated....TR allows them into much lower numbers, which is why the extra testing.
You can always start with one and change your mind later ..but we are stickers for the extra testing with TR simply because of the risk associated with it.
Example - look at my spreadsheet starting in April. I followed TR the whole time, but you can see that I had him very nicely regulated with fairly minimal testing (a la SLGS). Then ignore April til early July, because that was issues with his underlying conditions flaring up. Then in July, we hit the numbers TR is aiming for (50-100) and you can see aaallll the extra testing. Granted, he started medication for acromegaly (which significantly lowered his BG) so there was probably twice the testing there would have been with just regular TR.
Let me look through some spreadsheets and I'll take a few people here/link some posts
