Struggling To Run

My doctor suggested I go on a low carbohydrate diet to lower my insanely high triglycerides. I consulted with a nutritionist and she suggested I try to consume between 1,800 to 2,000 calories a day. This would allow for moderate weight loss. My doctor also said I should lose 25 pounds. (So far, I’ve only managed to lose 5 pounds in two years.) Honestly, I was perfectly happy with my fat Green Girl body before she bursted my bubble.

Based on the recommendations from my doctor and nutritionist, I calculated the following ranges. I’m supposed to eat at least 1,800 calories a day but I started the range at 1,600 because I find it hard to eat more than 1,800.

% From To
1600 Calorie Diet 1800 Calorie Diet
Calories grams calories grams
Carbohydrates 45 720 180 810 202.5
Fat 30 480 53.33 540 60
Protein 25 400 100 450 112.5

To calculate the carbohydrates, fat, and protein, each gram of fat contains 9 calories and each gram of carbohydrates and proteins contain 4 calories.

Truth be told, I had a really hard time following this diet plan when I was marathon training. When my long run mileage hit 10+ miles, my appetite became ravenous. I also craved sweets so I indulged myself in way more fruits that I should have.

Now that I’m starting a new training program, my mileage is starting off low so I’m trying to keep my carbohydrates to 45%. The only problem is that I seem to run out of energy really quickly. I went running today and struggled to complete 5.2 miles before I had to break down and eat a grapefruit because my body was craving sweets so badly.

I’ve talked to other people who do low carbohydrate diets and they said they actually have more energy but this doesn’t seem to be the case for me. I’m going to have to work on this. Perhaps if I consume the bulk of my carbohydrates right before my run it will help.
