Hi all, I wonder if someone could help out here, this is a bit long so please bear with me. On days that I train in the morning I seem to get a huge spike later in the day after a protein shake let me explain below: 7:30 - Take morning insulin (reduced dose due to training) 8am - Breakfast (porridge with natural peanut butter and 1 scoop protein powder 60gC 29gF 43gP) 10:00 - Training 12:00 - Post training lunch (80gC 20gF 50gP) for this I take a slightly reduced bolus rate otherwise I am hypoing all afternoon. The above keeps me in the 4.0-5.5 range. 4:00 - Snack time - level is usually around 3.8-4.5 here so I take a protein shake (15gC 7gF 48gP) and this ends up giving me a HUGE spike after a 2-3 hours anywhere up to 12-17. I am using the USB Pure Protein GF-1 powder by the way. https://uk.usn-sport.com/en/pure-protein-gf1 Does anyone know why this is happening? I can understand that by 4pm the lunch time bolus has run out surely the basal can deal with the 15g of carbs. I’ve been a diabetic fort about 40 years plus and using this powder for quite a few years whilst on the twice a day human M3 insulin and NEVER had any issues with it; the highest it would spike me might be to a 7 or an 8. I’ve switched over the MDI (NovoRapid and Levimier) a few months back and protein shakes are causing havoc. Any advice would be great.
