<human>: So first off I'm 25F 5'2" CW 240, GW ~150. A little background, about 1.5 years ago I was at 180 and pretty happy with my weight. I was very active, I was a zookeeper so walked 10+miles daily, and regularly lifted and carried 70+lbs. I was also an avid horse back rider, riding 3-4 times per week plus cleaning stalls etc. Well in short succession I quit my job, my horse had to be euthanized, and I moved across the country to CO with my bf. Since then the lifestyle change (I'm now a nanny), mild/moderate depression, and legal weed and so many delicious craft beers added up to a 90+lb gain. 

Well I'm trying to get back to a healthier weight and lifestyle, but I've never really worked out/dieted before so I'm a little out of my element here. I've been going to the gym 5x per week for the past month or so, but haven't done much dieting wise. What I do at the gym now is 30-45 min of cardio, 20-30 minutes of weights rotating days between arms, legs, and abs, and 10ish minutes of stretching for a cool down. Diet-wise, I'm now looking into keto, low carb type diets (thanks FAQ!) but again, I've got no real experience there so any advice is welcome.

So what I'm looking for here is just any advice, tips, or help on what I should be doing at the gym and in the kitchen to help me get where I want to be. Thank you in advance!
