Maybe it's because I've been at it so long, but LC eating feels normal.
FOr breakfast I had the most delicious eggs with ham, bacon, onions, mushrooms, swiss cheese, fried in delicious butter and bacon fat.
I didn't eat till late, and when I did I had peas, carrots, chicken (LOTS of chicken :yum
and a ton of broccoli.
Just 5 mins ago I had a fudgy brownie (2 carbs and as good as any made with sugar and flour) with a bit of whipped cream, almonds, and low carb milk.
People always talk about eating "regular" but to me, this feels regular. I can eat anything I want, because anything can be made low carb. If I want fruit and yogurt, yep. Cereal, yep. Brownies and milk? Yep. The good news is, most of what I REALLY want is stuff like tons of chicken and broccoli... or egg omelets loaded with veggies and cheese. Ya know, real food. I just want a smattering of the sweet stuff. It feels normal and regular to me.
Except unlike regular eating, I don't gain weight instantly like alice in wonderland, and I don't feel ravenous, and I don't get hypoglycemia, etc.
I think a litmus test for a "normal way of eating" is if you have to eat a whole lot of fake food as meal staples. On LC I eat food as it is. I don't have to eat fake meat and fake cheese and all other crazy crap that people eat on "regular" lower fat diets.
The only fake foods I eat are foods that are already heavily processed to begin with (example, instead of store brownies and fudge I make my own with dark chocolate, and various artificial sweeteners/flours). In this case, I'm replacing bad processed food with better processed food. Ironically, in my brownies I'm keeping all the nutritionally redeeming things (dark choco and butter and eggs) and only replacing the stuff that is ungodly unnatural and unhealthy (sugar and flour). If I were doing a "regular diet" odds are I would keep that sugar and flour, but replace those beautiful eggs and chocolate and butter with something less healthy like applesauce and egg whites and cocoa powder (not as healthy).
Bottom line? This is the better way to eat.
Yes, in order for it to work it has to be a way of life. That's true of anything you do to lose weight.
The body always gains weight back plus some if diets are discontinued (it's an anti starvation response - you are more sensitive to blood sugar spikes and creating fat and making new fat cells and all that fun stuff after weight loss).
Seeing as this is the better way than low fat or eating less cals of junk, and the foods we eat on LC are usually those with the most nutrients, and seeing as it has to be a way of life anyway...
I think LC is the best choice.
There's more than Atkins, not everyone needs to eat that low anyway... plenty of LC plans allow for slightly higher carb fare more regularly (like fruits).
If someone can't make a LC plan work at all, odds are they aren't ready to make any plan work.
As for vegetarianism and LC, we have plenty of LC vegetarians. There is even a subforum for the veggies.
