Quick question, I'm on week 5 now of C25k, it's been going well! I certainly haven't been feeling tired, sometimes a bit bored but not tired. I have noticed my weightloss has stayed the same frequently in the past few weeks as my jogging is increasing . I have also noticed that after my mid week sneak peak weighin I have normally lost a pound or more from my weigh in day, but then gain it back by the weekend. I think I get really excited about the the numbers so I eat less on Tuesdays and Fridays to ensure a good weigh in Saturday. I have my final run on Fridays and swim on Thursday. Is it possible within these 2 days for my body to go into starvation mode? I have noticed I'm just not eating all my RMR's 1400 calories on workout days.. Is this really why I am STS ???
