Food: When shopping at the store, try to stay away from the aisles, shop on the outside of the store. (Meats and veggies)
Don't eat until you’re full. Learn to moderate. At the end of the day lowering your calorie intake is the biggest factor.
Training:Just get started, you have to make time. And accountability is extremely important whether it’s with family or a friend. If you have the money invest in a trainer they are experienced (most of the time) and will start you at a level that is appropriate for you.
Anyways best of luck to you on your fitness journey. Keep crushing it
