Ive had it 
I have a little under a stone to lose. Started a diet that worked wonders after dc2 week before. I am still nursing (dc3 8mo).
Diet:
Bfast: protein bar (3g sugar)
Oolong tea
Lunch: syntha 6 protein powder mixed with water and frozen fruit
Snack: variety. Usually one of the following: 9 bar, naked bar, handful cashews, apples or other fruit. Sometimes boiled egg.
Dinner: chicken (with or without skin), sweet potato, kale. Or fish, sweet potato, veg.
I am having around 1600 calories a day (1200 plus 400 for nursing).
Losing NOTHING.
I am also bloated and constipated despite taking this special "detox" colon cleanse tea, eating apples before bed, and lots of water. I can go 3-4 days with out a BM. After a BM I weigh a lot less so surely it's all water and poo?! How do I get my gut moving faster?
What else am I doing wrong (don't say eat more because I can't)!
Drinking 1-1.5l water plus oolong tea
