I am hoping to lose 1kg a week. Now i am at a rate of about 200g if at all, a week. I just don't understand why it isn't working. The moment I go about 1700 calories I start gaining weight. It doesn't make any sense at all because I've read many threads basically pointing to weight loss as calories in < calories burned. I am going under AND I don't up my calories on training days either.

1. I went through quite a bit of diet in the past, always lose a good number and then throughout the years because of stress and other issues put them back again. I lost 23kg in about 4 months not doing any exercise at all, just watching food a year ago. I've gained about 10kg back since then which is why I wanted to change it, but this time including gym.

2. I am losing barely any weight at all. Regarding workout, that's why I shared the link to ask for comments but so far nobody has commented on it.

3. I drink about 1.5L of green tea (2 tea bags in  massive tin cup) and 1.5L plain water daily. That should be enough, no?
4. Eat above and gain weight. I'm scared now. Maybe the weight gain is temporary and I need to do it for longer. Will try for a week see how it goes.

Can anyone tell me the normal daily calorie intake for 25 yr old man to keep the weight?
