After several triathlons at the shorter distances and a successful (for me) HIM under my belt, I decided to do a full IM. I'm using the 36-week (ouch!) training program on this site and decided that I'd also start looking more closely at my nutrition. In the past, I had the "train hard, eat whatever you want" mindset and it worked fine, but I thought with all this work I'm putting in, I should probably also consider my nutrition as an important part of my training.
I started using the website "My Fitness Pal" to track my calories burned and caloric intake. You can customize it to track your % of carbs, fat, and protein. After a bit of research, I settled on 60% carbs, 25% fat, and 15% protein.
Anyway, I'm just a smidge under 6 feet and usually weigh somewhere between 180 to 185 pounds. After a 12-week or 18-week training program I end up closer to 175 pounds.
Well, here I am in week 15 of 36 and I'm about 158 pounds - losing about 1.5 pounds a week for the last 15 weeks. I'm still considered "normal" when I look at a BMI calculator (21.4 BMI), my energy level seems fine, and I just won my age group at a sprint tri last weekend.
For those of you who have made this jump from HIM and shorter distances to full IM, have you experienced a similar thing? Do you think my weight will stabilize at some point? Should I be eating more? I'd love to get a bit of feedback.
