starting?

really overwhelmed with where to start - currently 176-180 lb at 5’7”, would really just like to be back to mid 150s-low 160s where i feel curvy but confident. this is the heaviest i’ve been since college (190s) and have slowly put on the weight the past 2-3 years from work stress and comfortable relationship weight. i’m the most active i’ve EVER been outside of high school sports, almost 30.

wondering about going through FSA store or where may be best? i don’t imagine i’ll qualify through PCP since BMI isn’t 30+.
