I started on a Keto diet last Thursday. So trying to keep carb intake around 50g a day. However I am not manically counting every gram I eat. I just keep away from processed foods and think more about what I stuff into my mouth. So far it is pretty good.
The pros and cons so far have been:
+ No hunger (except for the first two days when starting)
+ Feel energetic in the morning
+ No hunt for sugar highs to feel energized
+ I can eat almost all the fatty foods i like! Mmm... Cheese... Bacon...
- I cannot eat all the sugary stuff I like
- A bit more expensive than regular diet
Anyways, I am trying this out for a couple of weeks to see how it goes then decide what to do.
I am on the keto diet. I stay under 20g per day though.
I do agree with your pros, and one of your cons, but I don't necessarily think it's more expensive than a regular diet. It's really all relative to what you eat and how much. Maybe it your case, it is. Of course, if I choose to eat a steak for one dinner versus bologna sandwiches for a week, it comes out cheaper.
I think the biggest thing I've noticed is that it has had an added effect on me of causing me to want to choose better foods to eat, so the price has definitely increased. Though that's not necessarily a bad thing.
I will say this: I probably have the biggest sweet tooth of anyone you will ever meet. People always wonder how I can handle this diet. I think I have pretty good control of my will. I have always made an effort not to try all of the sweet recipes that people come up with to comfort themselves during this diet. I've always felt like that would just remind me of what I'm missing and make me want it even more. Best to keep it out of your mind and focus on the good things like bacon and cheese on everything.
Also, don't try to cheat every week. It defeats the whole purpose. I personally don't cheat at all, but if you must, try to get as much time on the diet in as you can before doing so.
