I'm here! I am not on reddit anymore, and I drop into the community once a week or so, but I usually read all the posts here.

I started tracking my calories again about 3 weeks ago. I've always been aiming for 0.5-2lb/week loss, but I always ended up cutting too much when I hit a plateu, or drank too much water the day before weighing, and it wasn't sustainable.

This time around, I've been only going off a weekly moving average for actually comparing my weight. Even though my daily weight can look really noisy (±2lbs sometimes) it's showed I've been tracking about 1lb loss per week pretty closely. I wish someone told me this sooner, I devoted way too much energy trying to lose 0.14lb/day

Specifically, I think the abilty to make hydrogren from renewable resources at large-scale will change everything. Hydrogen fuel cells are more space efficient, and require less toxic manufacturing, when compared to current renewable energy generation and storage methods. If hydrogen is seen as cheaper or more green than other power sources, it will change the market completely.

Hydrogen generation is also an active research area, and just this year they've have some promising results for renewable hydrogen.
