I have been exercising and eating healthy yet I still manage to gain weight, why?

Q: I've been exercising (cardio and weightlifting 5 times a week) for three weeks now combined with eating healthy (about 1500 calories per day) and I've actually managed to gain weight!

Mozzy: 5 times a week weightlifting is too much! The rest period is crucial if you are following a strength training program. Try not to work a specific muscle group more than 2 or 3 times per week. Also, try increasing the intensity and/or duration of your cardio routine in a few weeks.

The good news is that you said you've only been doing this for 3 weeks.  That's simply not long enough for some people to start seeing results.  Be consistent with your routines and patient with the results.
