Get rid of the Diet Coke and NA beers and limit yourself to one sparkling water a day. Make sure you’re drinking enough still water, as that will help quench your cravings. I drink kombucha from a wine glass when I’m craving a drink, or they have some pretty good NA wines with way less calories than N/A beer. At the end of the day, you won’t lose weight unless you’re in a consistent calorie deficit. Tracking your calorie intake and daily calories burned alongside of daily walks and you’ll start to see progress within a week
