I've been trying unsuccessfully for over a year to lose weight while training olympic weightlifting. I was using the MyFitnessPal phone app. MyFitnessPal is great. It's easy to use and can be used anywhere. When using that app I assumed my metabolic rate was around 3000 calories a day. It was 3300 back when i was training triathlon 20+ hours a week. I assumed it would be slightly lower now that I was olympic weightlifting 4 times a week. I was wrong, and my assumption caused massive problems. I'd start dieting, I'd plan on losing 2 pounds a week. If my metabolic rate was 3000 calories a day and there's 3500 calories in a pound of fat, I'd have to cut out 7000 calories a week, which is 1000 calories a day. So I'd eat 2000 calories a day plus any calories I burned from workouts.
3000 (metabolic rate)
-1000 (calories per day for 2 pounds weight loss a week)
2000 (calories consumed per day)
Using this formula I'd get hungrier and hungrier everyday until I couldn't handle it anymore and I'd binge eat gaining more weight than I had lost. I decided to stop using MyFitnessPal and go back to using Dietpower. Dietpower is a program similar to MyFitnessPal, but the biggest differences is that Dietpower will figure out my metabolic rate, MyFitnessPal doesn't.
Now that I've been using DietPower, it's shown me my metabolic rate is much higher than 3000 calories a day. It's 4130 calories a day to be exact. That makes a lot sense as to why I was overly hungry and why I need more calories now. Muscle burns calories. I'm burning more calories now that I'm a weightlifter and have more muscle then I did as a triathlete.
Since starting to use dietpower I've dropped from 311 pounds to 299 pounds without being very hungry at all. So the good news is I'll be able to be more loyal to this diet because I'll be more comfortable. The bad news is I've decided to limit my weightloss to 1 pound a week and at that rate it will take me 68 weeks (May 2016) to get to my first goal of getting into the 105k weightclass. And it will take me 93 weeks (Oct 2016) to get to my 2nd goal of getting into the 94k weight class.
