Why am I not loosing weight

I have basically the same measurements as you and I've lost 17 pounds in 6 weeks. It was slow and steady in the first 4 weeks but I've been losing more rapidly as of late. Here's what I've found worked...

1) Drink TONS of water, I literally drink at minimum 10 cups a day and usually more than that.

2) Avoid sodium, and thats basically what people mean when they say avoid processed food and eat cleanly. That basically means eat "whole foods" (not meant to be a play with the store name). Which means if you're going to eat chicken, buy plain chicken at the grocery store instead of like chicken nuggets. Really it means eat everything in its most natural form, if that makes sense. I started with eating the weight watchers/lean cuisines everyday for lunch and I lost REALLY slowly, when I cut them out completely and started taking a baked chicken cutlet or salmon or something else like that for lunch I did MUCH better.

3) Up your protein. I get my protein from shakes (which I only do like once a week because I dont particularly like them), egg whites, meats, etc.

4) Make sure you eat breakfast!

5) Eat at least 5 times a day. I changed my diary to be "breakfast" "snack in between breakfast and lunch" "lunch" "snack in between lunch and dinner" "dinner" and "post dinner." Obviously to stay in your calorie goals you have to make each meal smaller, but it keeps your metabolism going at all times.

6) Avoid white... anything. White pasta, white bread, white rice...

I hope this helps!
