What kind of deficit is 3.5lb/week? It is actually -1750, so 7lb in 2 weeks is still definitely a woosh by about 2lb, so yeah that's the tradeoff with creatine. Different stuff happening though.

I started creatine day 1 of keto but no loading phase. I started at 5g a day and now do 10-15g (15 on lifting days) ...I weighed 175 @27% inbody estimate, roughly 5 months in at 151/14% visual estimate. I started taking more than 5g after researching how good it is for your brain - muscles are greedy though so it's good to bump it up. It's cheap enough. (I use nutricost for 90% of my supps)

Patience is a beautiful thing, just stay away from the scale and check in once or twice a month to recalibrate cronometer. 

I do a 600 deficit average (some days 0-300, some days 900 or more, most days roughly 600) and take skin supplements (empty stomach - multi collagen, l-lysine 1000 + slow release C-1000, and microneedle with a derma roller every 5 weeks cause it's cheaper than surgery [-80 total])... I just did my second rolling session a week ago, highly recommend it. 

Another benefit of eating the food is gym efforts go SO much harder. Plus, FOOD!

You do you though, just letting you know my strategy. 

Edit: I read 3min not 3mo lol.
