I am a 5-ft. tall, 110-lb. female. I started the Stronglifts5x5 program (3 days per week) about 2.5 months ago, and I cycle on 3 off days and take one day of complete rest from exercise. No known medical problems besides hypoglycemia, which I've controlled for years by eating every 3-4 hours.
Within the last couple of weeks, I've begun to have intense hunger pangs in the afternoon, as if I hadn't eaten for a day or two. I would eat and eat and eat until I was stuffed, including high-calorie junk food, but the hunger pangs would return within a couple of hours or less. I found that eating Clif Bars was the only thing that eliminated the hunger, so I assume that I'm not getting enough protein. My regular diet is high-carb vegan (mostly raw oat bran, potatoes, and brown rice).
I've tried adding legumes to my diet, but it's not working. Protein bars are the only thing that satisfy me. I'm having 15 g Livfit protein powder with breakfast, but I still begin to get hunger pangs at lunchtime.
I'd rather avoid processed foods (protein powder and bars), but I don't know what else to do at this point. I feel like I'm starving to death 2–3 times per day. What other high-protein vegan foods can I try? I'm also trying to lose fat, so I don't want anything fatty.
Stronglifts does not seem like a heavy-duty lifting program, and I'm only cycling for half an hour, so I don't understand why I seem to need so much protein.
Thanks for your help.
