Any suggestions on loosing weight for an active 50 year old? Started to gain weight and can't seem to get it off...Like 25 lbs in the last 3 years. I'm really depressed and am pretty active, seems like I can't eat any less and the keto diet does not work for me. Going for blood test to see where my hormone levels are. Already started taking progesteron and estrogen suppliments to help with hot flashes.
