Hi guys I'm new to this board and I could really use some help I hit a plateau about 4 months ago and I can't get past it. I am 5'7, 145 lbs wanting to get to about 135 lbs. I have changed trainers and nutritionists and cooks several times. ANY imput would be much appreciated!!!!!! I see my trainer 6 days per week. 3 days are mainly cardio, 1 day upper body, 1 day legs, 1 day core. My diet is a compromise between what my nutritionist thinks is healthy and what Ive been reading on bobybuilding. A 1600 cal/ day low fat low sugar diet. A sample day would consist of:

high fibre cereal 150 cal
1/2 cup skim milk 45 cal
1 scoop whey 90 cal
6 oz Chicken 300 cal
1/2 cup rice 110 cal
1 cup mixed veggies 100 cal
1 orange 80 cal
1 can tuna 170 cal
1 scoop whey 90 cal
6 oz Halibut 250 cal
1/2 cup rice 110 cal
1 cup mixed veggies 100 cal

When I whine to my trainer she tells me that my weight isn't changing because I'm replacing fat with muscle. I find this hard to believe since my clothes don't fit any different. Other people tell me that now that I'm a mom my body composition is different and will not change. Ive tried clen, tried stacking caffine asprin and effedrine, but haven't lost a pound. Any suggestions?
