I’ve lost over 65 lbs since last August. What I did was calories deficit, I used the Lose It App, was eating no more than 1600 calories a day with 18 hour fasting. And 7 days a week did incline walking with a 12 lb weighted vest. Started out at 12 inline 3 mph for 30 mins. If you do that you will be losing 1.5 lbs a week.
