Citrus? Really? Grapefruit juice? Isn't that high in carbs? I can't do green tea. I'm super sensitive to caffeine. The last time I drank green tea, I ended up with a horrible stiff neck. My chiro says I'm sensitive to the methylxanthenes (sp) in coffee, tea, and chocolate. I can drink one cup of coffee and have minute pieces of chocolate. But the green tea is a no-no. I eat tons of raw veggies and I take fish oil every day. I love citrus, though -- especially grapefruit.
From experience, you will lose weight from the outside in. The first thing to go are fat fingers and toes. I've finally gotten within 15lbs of my goal weight, and it's almost all around my belly.
Belly fat is the last area to go. Just keep on eating right and following a good primal exercise plan. It can be difficult and often disappointing, but keep at it.
I'm finding much change in belly fat more recently as I've added push ups and pull ups to my walking. It's still my most jiggly area, and will likely take a long time before I'm satisfited, but just the fact that I'm seeing the change makes me feel better.
Hope things start to work for you!
