Here's how to calculate your daily intake of calories/day based on your activity... Calculate your
BMR and then based on that your
daily calorie intake on your activity level. Use this as a guideline to help you figure out your calorie/day. Don't estimate or guesstimate your food intake. Measure and log everything you eat. Even if it's just 3 almonds. Trust me, it all adds up. I know I've been there done that.
I was stuck for a bit too and apparently I wasn't eating enough. I do workout 6 days a week at home. You don't have to workout every day but do what you can. And, yes, consistency is the key. If you can't join gym yet, walk (like Robin suggested), jog in place while watching your favorite show, take stairs instead of elevator etc get your heart rate up...little things make a difference. Also make sure the exercises you are doing your form is right otherwise it won't help.
And whatever changes/modifications you make to you WL plan give it about 2-3 weeks to see any change.
BTW are you eating snacks between meals?
