Trying to change lifestyle

I’ve been logging my food now for 7 weeks. Trying to keep my carbs down below 65 per day. Calorie intake about 1400 per day. My weight was 237 when I started. I’ve lost 16 lbs so far. I walk 2-3 miles each workout 3 or 4 times a week. I’m going to get down to 180 lbs at some point. There are days when I eat some crap or drink some beers, but get right back to the routine the next day. The low carbs was hard for me. I’m on the road every day for work and had to cut out eating out and now bring my lunch every day.
PS: I’m a 53 yr old male
Any suggestions would be helpful.
