I've been going to the gym regularly for about 6 weeks now. 3 days a week I do an hour of cardio and the other 3 days I do cardio and then weights with a trainer. My tolerance and endurance have been steadily improving...until today.

I did my cardio with no problems, then met with the trainer. From the get go I knew something was off. I was getting winded way too easily and sweating more than usual. Finally about half an hour in, I was doing some leg extensions with a cable and I felt nauseous and dizzy and the lights started to dim, so I sat down immediately. I have never passed out before, but I assume that's what almost happened. I never want to feel that way again.

My trainer said I need to eat more on training days, because by the time my cardio is done I've already burned off most of the calories I consumed for the day and my body has no fuel left. Makes sense, but I'm afraid that my weight loss will slow down or stop. Am I right to be worried? Anyone else have a similar experience? I'm sure having my TOM isn't helping either but my body's reaction still seemed pretty extreme.

listen to your trainer. you are burning fuel and then you have none left essentially. try some greek yogurt before a workout or a smoothie. you work out more, you burn more, you eat more. you will lose more inches than lbs, there is an almost 2 month "lag time" from inches lost to lbs lost. but it will catch up. i have been told and read that eating more protein will help you lose the weight as it builds muscle.
