You should use one with an AMOLED dark mode. Usually the screen uses the most battery and if your phone supports AMOLED it actually turns the pixels off to make blacks, which is more energy efficient. I have Connect, Liftoff, and Jerboa and they all offer it as a theme option although Jerboa calls it System Black (I think that’s the same thing anyway).

I use SyncThing to backup our cell phones to my on-prem server, and then use BackBlaze Personal Backup for a cloud copy.

Almonds are great. I’ve also been eating a lot of walnuts lately – I didn’t used to be a big fan, but since starting keto I’ve really appreciated their Omega-3 profile, and they’ve actually grown on me. Also occasionally macadamia, hazelnuts, and a couple Brazil nuts. Nuts have a lot of calories but are great to fit in.

First, congratulations; 10-11 kg is a great start!

Are you tracking your macros? How much of a caloric deficit are you running? Do you know if 50g of carbs is keeping you in ketosis? (20g is traditionally used because it pretty safely keeps you in ketosis, but some people can consume considerably more carbs and still stay in ketosis.)

Are any of your other metrics changing – pants/belt size, etc. Sometimes you can drop a size without actually losing any weight.

You could try intermittent fasting. Sometimes that helps people jump-start things.

I haven’t traveled extensively while on keto, but I recommend planning ahead. Scope out the restaurants and grocery options where you’re going and make a plan for where and what you’ll eat. It’s really overwhelming figuring out where to eat after traveling all day - having a plan will help prevent you from defaulting to old eating habits.

Also, bring snacks with you - nuts, jerky, maybe cheese, etc. Stuff that will get you quick low carb fat and protein calories, but that travels well.
