Specifics I don't have access to, just plug in a search for the string M1T blood sugar and you should get the relevant hits. As for weight gainers it depends on the type of carb. Complex carbs would be best for a more even blood sugar level throughout the day. So, just adding sugar doesn't quite do it. Might make it worse compounded with a high insulin spike and then the crash afterwards. As to why M1T lowers the blood sugar so much, no idea. If I remember my bio right sugar is processed in the liver and so the strong effect M1T has on liver function could result in all kinds of cascading effects throughout the body for processes that depend on the liver most directly.
