I can lose weight doing a lot of things. In my lifetime, I've lost hundreds of pounds. I am only able to consistently keep them off with low carb. Like cheesebiscuit, I have insulin resistance and auto-immune issues, as well as some other things. And, like cheesebiscuit, I have food addiction issues centred around carbs.
I would love for things to be different for me, and I could keep things off by "eating less and moving more". I actually don't like eating meat. I am me though, and I cannot control my consumption of sugars and starches for long periods with out cutting them down drastically. I was successful maintaining a significant weight loss with low carb by eating some starches and sugars in small amounts, but my health problems returned.
I think that people approach obesity and weight loss from the wrong angle. They constantly treat it like it's a defect of character and about personal weakness. However, those who maintain a weight within normal weight limits naturally shouldn't break their arm patting themselves on the back. Their bodies tell them when to eat and when not to eat. Fat peoples' bodies are out of whack in that regard. Otherwise, before the discovery of the calorie people would have ballooned wildly or lost too much too quickly. People who aren't fat or aren't too skinny would be constantly monitoring their daily activity (taking into account their lean body mass on that day as well), weighing their food, weighing themselves. The margin of error for weight loss and gain is too narrow. Off by a hundred calories a day (about a UK slice of bread), and you gain or lose ten pounds in a year.
I am not saying that I've never overeaten when I knew I shouldn't. I am a food addict. That's what we do. I have found something that works for me to boost my self control a bit. And no, it's not about limiting food choices. I have plenty of tasty things from which to choose. I am eating none or very little of the food to which I am addicted. It fixes whatever has gone wrong with my food monitoring system, and I can eat but I don't eat to excess (often).
I am not saying that it's the only way. If people have found other ways of doing it, I feel great for them. I just don't know where I would be without low carb.
It's not how the media portrays it. Sure, some people might eat only meat and cheese on it, and that's their business. I eat mostly whole foods, green vegetables, and yes, meat, eggs and cheese. I never rely on supplements such as Atkins shakes, and I always recommend that people avoid them unless it's an emergency. I eat what you might find in a gastropub almost every night. I am happy, losing weight (albeit slower than when I was at my heaviest over a hundred pounds heavier than I am now), but more importantly, I am healthy.
One of the things that have saved me has been finding a low carb plan that works for me. I think this is important no matter what sort of weight loss method works for you. For some people, moderation works, but for others, they need something more structured. I found Neris Thomas and India Knight's "Idiot Proof Diet" (not to be confused with diets of a similar name). They have an excellent cookbook to go with it with tonnes of recipes, especially for "problem" meals like breakfast or packed lunches. It's sort of a no counting low carb plan. It's not perfect, and it's definitely geared to UK dieters (a plus for me actually), but it's what I've come back to after about 9 months of trying to return to vegetarianism (my mind's "ideal" diet). It's very geared towards women, and there's a lot of self-help stuff in the plan. But I've low carbed for years and know the ropes. For a beginner, I'd recommend Atkins, but beware of the processed stuff. Aim for whole foods, and Atkins is an excellent plan.
Again, I am not trying to say it's the only way for everyone. It's the only way for me.
As for weighing: I weigh every day. It isn't always great to do that. You can get discouraged, but it does help especially when you're not dieting to keep an eye on gains.
As for exercise: I did a lot more structured exercise when I was starting out on low carb in '07. I do periods of semi-idleness followed by big adventurous bursts of activity. I manage both fine and probably better than some people a lot thinner than I am. I am considering starting a moderate weight training regimen.
Whatever you choose, know that there are others that have been where you are. Millions others. I wish you the best of luck, and I hope that things go well for you. Drop me a PM any time you'd like encouragement.
