i dont understand how I lost 80 pounds and now it stopped 2500 calories seems like alot, can someone explain why the weight loss stopped?
Dieting is a stress. Our body, being a lot more complex than most assume, likes to adapt to stress. It's likely how we've survived as long as we have considering the sheer stupidity of most people. Even they don't know it, their bodies automatically adapt for survival.
That said, as you diet using any approach, your body is going to resist your efforts. Fat is the perfect fuel source. It doesn't take a lot of energy to maintain it. It also is very energy-dense, meaning it's got more stored energy for utilization relative to the other tissues of the body. Our bodies *know* this. When you diet, adaptations start to occur in order to preserve the fat.
Now, when your very overweight, these adaptations can take a very long time. In most cases, assuming *sane* dieting approaches are used, I believe most people can reach their goal weights without ever having these adaptation halt weight loss entirely.
That said, your approach wasn't very sane.
The harder you diet, at any size, the faster and harder your body will adapt.
Follow me?
Oh, and someone was mentioning the starvation mode. It's not an event that happens. It's an entire host of physiological adaptations that happens over time. It's a process.
