Cat Woman - The usual advice is as follows;
1. Don't for at least an hour before going to the gym and then eat within 30 mins of finishing. I tend to have snack about 4pm having had lunch at noon.
2. Eating later in the evening then its ok as long as your up for at least 3hrs after you eat. In addition, you need to avoid complex carbs as these take longer to digest. Thus, vegetables / protein / fruit and salad are good at this point
3. In order to maintain energy levels eat a little and often. Eating your complex carbs earlier in the day (breakfast and lunch).
4. As 5cupa says - avoid caffeine drinks and stay hydrated whilst training
Any other questions just ask, though I'd need to know specific aims. As various members will attest eating & training are a bit more than a hobby for me
