So if you are used to eating 5000 calories in pure junk and you cut out 1500 calories of it out sure you will lose some weight. However when all of your calories come from junk with piss poor nutritional value, you are going to feel like shit. So...it's not going to be a stable weight loss long term. Or at the very least you are still setting yourself up for long term problems because your deprive your body of necessary nutrition. I think a lot of fatties fail to see the bigger picture. Eating right and moving more isn't just about the weight you will lose. It's about the boost you will get in every other aspect of yourself, mentally, emotionally, and so on. A properly fed body goes the distance in the day, doesn't tire out as quickly. A properly fed body is going to have a more stable and healthy mind. The brain can think better when it's attached body is running with the right stuff. It starts with taking a bad diet and making a lifestyle change to have a good one! With-out it your attempt to lose weight is useless!
