I tend to forget.
I did do 5 on my last DL set, I didn't feel like I could push much more without hurting myself.
I need some diet help if you have some advice
Sure no problem. The most basic diet is 40/40/20. It's a scheme for dividing up your calorie intake so you get 40% calories from protein, 40% from carbohydrates, and 20% from fats.
To implement it you need to write down everything you eat for a few days, and total up your carbs, protein and fats, and see where your at, and therefore what you need to change to get to 40/40/20.
A secondary goal is to avoid processed foods as much as you can.
So once you get your totals figured out, what you'll do is create a meal plan for yourself, and at that time you can set your calorie total. For a person your height to trim down you'll probably want to be in the 1800-2000 calorie/day range. That aught to drop 1-2 lb/week.
The bonus is, once you get your protein-carb ratio right you'll start adding muscle more quickly, and your fat loss will accelerate too.
It's not as much work as it sounds like. Once you do the initial work of tracking your food for a week or so and get familiar with basic meal plans, it'll become mostly automatic.
