I need help with BIG weight loss!

You will need to work out at least 2 hours a day, low carb you are already doing, drink insane amounts of water, and you need to eat AT LEAST 1200, esp if u plan to work out 30 mins+ not under or your body will think its starving. By switching to low carb folks lose like 10 lbs easily so dont go on that, you need to work out. To win anything like that, 30 mins a day is kinda low.

BUT good luck to you! I dont stress losing it fast, your skin might not be as happy with it, but the main thing is keeping it off, because fast lost, fast gain.

Workout as often as you can for as long as you can, low impact preferably to minimise risk of injury.

Fast weightloss is great, sure. If you like saggy skin and short term results.

Just keep in mind that with higher amounts of activity level the body will need more fuel! Don't completely cut carbs! Just go for healthier ones (brown rice and whole grains), these are a major part of your body's fuel, ask any competitive athlete. Bump up your protein too if you're working out more, you need to rebuild those muscles. Don't drop below 1200 calories, as stated before, you're body will go into starvation mode and weight loss will slow down (the last thing you want!), And, last but not least, WATER, WATER, WATER! Good luck and don't give up!

The frustrating (but true) answer is: no one can answer this but you. Everyone's body is different, everyone's metabolism works differently. This is why people get into these knock-down drag-out fights on some forums: there are people who swear by being vegan, it's the only thing that worked for them. And there are people who swear by being Paleo / Primal, it's the only thing that worked for them. Neither group is lying. They're just different.

If what you're doing is working, stick with it. Even if it stops working for a week or two, stick with it (my weight loss, personally, has always been a monthly thing rather than weekly. I blame hormones). If it stops working for a long time, listen to your body and adjust what you're doing. Most of the time, if you're doing something unhealthy, your body will give you hints. If you do hit a plateau, the forums here are very good for finding suggestions to get over it. People are usually very supportive & helpful about sharing what worked for them. FOR THEM. But ultimately, it's going to be your own process of trial and error.

Remember that the scale is only one measure of success. If you are replacing fat with muscle, you will become more toned and less flabby and will lose inches around, even if you see the scale stay the same, because a pound of muscle is more dense than a pound of fat. Also, sore muscles retain water, and many other factors (even the humidity outside!) can make your body retain water & give the illusion that you're not losing weight. Just remember, the ultimate goal isn't a number on a scale, it's a more healthy lifestyle.

Good luck to you!
