I'm reaching the height of marathon training again, this time as a vegan (last 2 years it was as a lacto-ovo). I'm having some difficulty getting enough calories, though, running a minimum of 10 miles a day. My energy is a little low, I'm not recovering as quickly as before, etc. I'm not losing weight and I don't want to, but I would like to have more energy and I know that I'm regularly carrying approx. a 1000 calorie deficit! So, in order to fix this, I've been incorporating more legumes, grains and nuts/nut butters. But this has driven my fat intake up significantly. Of course, the majority of this is unsaturated, so does that make it ok? Fitday estimates my intake yesterday at 70 grams!!! That's DOUBLE what I was getting. Should I worry? Is there an alternative way to get your calorie intake up without having to eat constantly?
