I'll be starting a "keto month" along with heavily restricting my alcohol in August. I'm open to any advice you have on your keto journey. I tried Vegan-ish in April and it was meh. No weight loss, but I felt bloated. I *did* however sleep a lot better..
Getting enough fiber in your diet will take "some" work because of the carbs, so you have to kind of plan your meals. I'm overseas and some days the local DFAC isn't the best for a keto diet, but you make do. Google for keto recipes and you'll have a billion options if you can cook. There are a lot of simple recipes out there. For example, I dearly love alfredo sauce, but pasts is out. Enter zucchini and now alfredo is back. I'll add butter to eggs or even a simple chicken breast for the fats. You have to watch your protein intake too, so I'd Google for your bodyweight and recommended protein amounts.
You want to have no more than 50g carbs a day and that included dietary fiber. Benefiber is good for a day when I'm good on my carb count, but struggling for fiber (broccoli and cauliflower are great for fiber goals).
Daily, I try to have one avacado. Breakfast is usually 3 eggs with ham and cheese plus added butter. I shoot for 30g carbs, 10g per meal, to give me a cushion under 50g. If I have an "off" meal or borderline day it doesn't seem to matter.
Drink a lot of water. A decent chunk of my 14 pounds in a month is probably water weight.
Two go to meals for me are a can of tuna with things like red onion, mayo, mustard, and cucumber. While the mayo has fat I tend to add a little extra olive oil. You can also take a can of tuna and add onion, peppers, avacado, etc. and add olive oil and lime juice as a dressing.
There are a lot of simple recipes you can make and if you are eating at a DFAC, you just have to make some hard choices at times. With that said, I can't recall a meal that I ate, and hated, just to have something to eat.
The "keto flu." I didn't get it minus a headache at the base of my skull for a few weeks. A coworker never had any side effects, and it really put a hurting on my wife. Increase your sodium intake if you can, that seems to help some.
Good luck.
