Do you exercise? If so, how often and what do you do?
How much water are you drinking per day? Many people aren't getting enough even when they think it's plenty.

Looking further into your diary I notice you eat sugar-free sweets containing maltitol. It's a sugar alcohol but it's glycemic index is really high compared to other ones. It raises blood sugar because of this which could be your problem. It has a GI rating of 36-53 (depending on how it's used) and regular sugar has 60. I stick with stevia and erythritol (GI of 0) for my sweetners. If you're looking for sweets I highly suggest Lily's Sweets. The coconut dark chocolate is amazing. I also use the chips to bake with.

Remember to replace calories that you've burned off through exercise. Walking is fine but if you're hitting the gym then you need to replace them. Your water intake sounds good and I don't think that the water flavour packets are an issue. Try cutting back on them if you think you're having too many. As far as alcohol goes as long as you're sticking to clear liquors then there are no carbs. I drink whiskey & coke zero pretty often. Your liver will process the alcohol before it works on burning fat though so your body's fat burning is taking a short break while it's doing this. Your tolerance to alcohol is very low while in ketosis so you definitely need to watch how quickly you drink and how much.
It could be your nut intake so try cutting back to one serving a day.
Have you been taking measurements? They are a much better indicator of fat loss than the scale. I've stayed the same weight for months but clothes started getting looser so I know I was still losing fat. Cells also will replace fat with water once the fat has been lost. I think it varies per person on how long the cells hold on to the water. One day your cells will let go of the water and you'll drop in weight. It's called the whooshing effect.
Have you ever given thought to Intermittent fasting? A lot of people have really great results from eating this way. It takes a little bit to get your body adjusted to eating a large amount in such a small time frame but once you're adapted I hear it's pretty easy to go most of the day without eating. I know I have found that I'm not hungry in the morning if I have a huge dinner (1000+ calories).

I have serious chewing gum addiction. Just checked sugar alcohol/carbs for Trident Layers-2 gr per and I chew them all day long. Guess some behavior modification is in order. This group is very informative.

Coming to end of day 2 w/o my trident layers. Happy I'm no more blissfully chomping on extra 20g carbs per day

I have had great success with LCHF in the past. I decided I needed to lean out in November, and after a couple weeks I ran out and bought a bottle of coconut oil and made some fat bombs trying to get used to getting that extra fat into my diet. The week I started supplementing the fat bombs and coconut oil, I stalled and didn't lose anymore. I think your calories and exercise seem on point.

I was reading last night that for those of us trying to lose that adding in extra fat (your coconut oil in your coffee example) isn't necessary. As long as we keep the carbs low we will stay in ketosis and bodyfat will be broken down for energy. If you give yourself a super biologically available MCT oil as soon as you wake, it would make sense to me that would be the fuel that gets used instead of body fat. Maybe try working out fasted in the morning and only go for the fat bomb/coconut oil coffee if you notice you need a pick me up that day.

eddiecastro77, try

Protein Daily Intake: First: Calculate your Lean Body Mass PDI should be 1-1.5 g per Kilogram of lean body mass. (convert lbs to kg!)

When in doubt eat more fat! If craving carbs, grab a slice of cheddar cheese wrapped around grassfed butter... AND hydrate, hydrate, hydrate with added sea salt. Note I squeeze and add some lemon in (1 lemon has 1g carb) cause it tastes better.

Hi Eddie.."but my ideal weight is 185 for my height of 5'9." is this the US Gov advice? The same folks who designed the pyramid with heavy carbs as the base of ALL eating? what if, just if, that 210ish is where you will be naturally without modern interpretation intrusion?

Here's why, I read a study where they had a guy who was a his ideal weight, keep adding more and more calories, like thousands. He was overeating strenuously..and after ~3 months he only gained 3.5..his body just could NOT get fatter on Keto diet…he was where his body naturally wanted to be….it may be similar for you…family history, genes are a really big part..the one thing we can't change.

Even if you fight your way down you may not STAY down, by design.

the study was to prove normal set point people WON'T become fat with eating butter, etc. will find it and post, it may have been in Good Calories, Bad Calories book, which is super dense data!.

If you feel good now, and want to be super cut…for a short time, not decades, then pushing yourself will be done by constant effort.

Good luck! (PS I emailed you on a daily/weekend-doable IF called FAST- 5, eat all foods in 5 hours, any 5 hour block you choose, fast for 19 hours..takes ~30 ays and young men do better than older everyone.

http://mann.bol.ucla.edu/files/Diets_don't_work.pdf << this is a study of studies, it backs up just ~4.6% of Americans diet and keep it off..but of 100 million dieters, ~4.6% is 5 MILLION people telling fat people to just diet and exercise, cause it works for them.

I don't know if I agree that 210 at 5"9 would be his natural maintain weight unless seriously broad/muscled. I was 210 at 6"0 while doing mandatory PT and moderate lifting and still was pretty chunky.

I would definitely try IF and cut out everything to just water and basic foods to see if its something sneaking in carbs or spiking you out of ketosis. Once you are comfortable and see that you are solidly in ketosis and losing again, then you could slowly reintroduce everything and monitor it.
