Yep, did it for about 3 months at the beginning of 2017.
The first week or 2 are difficult whilst you go thru the adaptation phase.
You might get some headaches/lethergy/general fatigue, but it will pass if you stick to it.
Your reasons for going onto a lower carb way of eating sound similar to what mine were.
I’m Italian, so we love our pasta, bread, potatoes, rice etc…, but I cannot control the quantities that I eat those foods, so I decided the best strategy for me was a diet that would necessitate removing them completely.
I’m an all or nothing type of personality, so I tracked my calories and macros reasonably accurately for the first 1-2 months.
Until I knew what I was doing.
I had some weight to lose, so I budgeted for a daily allowance of 2200 cals, which was surely a big reduction in the 3000 (estimate) I was consuming previously per day.
The weight fell off me effortlessly with very little exercise.
I believe I lost 10kg in 8-9 weeks, and then a little more came off in the next month.
There were days when I struggled to reach my 2200 cals, so I’d consume a Fat Bomb late in the evening to bump up my Fat macros.
You won’t feel hungry.
In fact, intermittent fasting (if that is something you want to try), is a piece of p*ss on Keto.
The biggest positive about Keto though IMO, is that it gets you thinking about what you’re putting in your body, and what you need.
You will buy Grass Fed Beef, Grass Fed butter, Cold Pressed Oils (Coconut), shiteloads of leafy greens, broccoli, cauliflower, mushrooms.
You have to be realistic though.
It’s a sacrifice when remaining in a state of Ketosis.
Family dinners out, functions, special events, consuming alcohol.
All those examples you are limited.
ALSO, you pretty much can’t consume fruit (berries are the exception) as there are too many carbs which will throw you out of Ketosis.
That’s a biggie !
I’ve been in and out of low carb since last year, but I plan on going back on to Keto soon, as I notice the kgs slowly creep up on you.
I like the discipline and structure it provides me.
Anyhow, happy to answer any questions you may have.
I researched religiously before I embarked on it, and have a few YouTube favourites…
