Hi Tink
Maybe your not eating enough. Remember if you exercising a lot your toning up as well and muscle weight more than fat.
Perhaps try going back to basics. Someone at my group was gaining and realised that because she thought she could judge how much her cereal for her HEX B was she'd stopped weighing it. It was the same with the HEX A and she was having loads in coffee throughout the day. It transpired that she'd been having loads more than she should. Are you remembering to drink lots of water? Our SW leader says to try drinking water when you think your hungry sometimes its not hunger at all. And remember not to eat it just because its free eat it because your hungry. Try to remain positive cos blips will happen hope this weeks better for you xx
