Well, as you can see from my original update the weight loss was fast and vast, so I've lost 1.1 stone since starting in January. I found that with no additional exercise I was stuck at a constant weight, so now the weight loss is very minimal (perhaps one pound lost every 1-2 weeks, rather than per day in some instances at the start of the program).
In early January I ordered a bike from Germany, and as it's hand-built I've had to wait until next week until I can begin the exercise phase (two hour commute per day, Mon-Fri). I'll need to up my dose from 3 servings a day to 4 servings to make up for the calories required to exercise, and only then will I be able to reply to this thread with some solid findings.
I strongly recommend staying away from bread, dough and other such stodge. A couple of times I've attended a Hackathon as part of my work, which includes free pizza, I'd give in, and my weight would increase and stay near to that for around 2-3 weeks. It's just not worth it after all the effort you put in prior to that. Only when using Huel 100% do I see the difference d/d, which is a shame as the novelty is beginning to (reluctantly) wear off.
How are you getting on?
