Hi all. Just joined and hoping to get some help. Been doing keto since April 2017. It has worked very well for me to lose the weight I wanted and to keep it off. I am actually getting a little on the thin side. I have a few things I am trying to iron out to keep from losing more weight and also to be healthier overall. I have a hard time getting enough fluids. I’m just not thirsty and if i try to drink plain water when I’m not thirsty it gets stuck in my throat. I started drinking coffee with heavy whipping cream but i have read it increases cortisol which sounds like a bad thing so i quit drinking coffee but then i lost another 5-10 lbs so i started again to stop that trend. Tried drinking broth regularly but it makes me retain fluids. Which actually kind of helps some things because it plumps up the tissues but it is seems it is hard on the heart so gave that up. I don’t use any no calorie sweeteners so that rules out a lot of things. So right now I am drinking coffee to keep up fluids and not lose weight. I also seem to have some trouble feeling cold. I have read about consuming more coconut oil which does help me feel warmer but it makes me want to gag. Any ideas on how to up my fats without upping carbs or protein without eating straight fats?
What can I tweak
Martha, let me first say “Welcome”, and then “Sorry”, because I don’t have any advice for you. 
I think it’s exciting that we are able to tweak our diets to suit our personal needs. That’s one of the things I like most about the ketogenic diet; it can be tailored specifically to you.
Now I don’t have any advice, but we have LOADS of BRILLIANT people on this forum, that I’m sure can help you out. Sometimes it takes awhile for them to get around to responding, but they will.
Good luck, and again, welcome to the forum.
Fatty steaks or ground beef will add protein and some fat without eating straight fats. Do you eat nuts, macadamia and pecans are low carb with good fats. Walnuts have both omega 3 and 6, in balance so they are also a good choice.
Remember coffee is a diuretic so I wouldn’t be drinking it all day long. Try water infused with lemon, orange, lime slices, cucumber or strawberry after morning coffee.
Good luck sorting it out.
No thyroid. Cancer 15 years ago. Lowered my thyroid replacement a little after I lost all my weight but still on the high end. Shouldn’t be any chance of being hypothyroid. But thanks for the input.
Thanks RobC. I don’t really exercise just to exercise but am quite active. Not sure if exercise was suggested to help me stay warm which it would temporarily I am sure but can’t be exercising constantly to stay warm.
Love prime rib and porterhouse steak. Just can’t eat them all the time. Absolutely on the coffee being a diuretic but it has made it so I’ll at least drink something so I can flush wastes out. I do try to eat nuts but looking for a few other ideas to fall back on. Need to look into the infused water.
You say you have trouble with feeling cold. That sounds as though you’re getting too little protein. Don’t worry too much about exceeding your protein; Dr. Naiman claims that too much protein isn’t even a thing, and Prof. Bikman worries that people aren’t getting enough.
Also, two points about weight loss on a ketogenic diet: first, keto is more about weight normalization than about loss per se, and second, we have lost sight of what “normal” actually looks like. True normal is considered emaciated by today’s carb-loaded standards, but look at photos of the kids at Woodstock, or of military men during World War II, for an idea of what we all used to look like before the U.S. dietary guidelines did us in. (I suggest those two events because you can see a lot of people with their shirts off, but any pre-1979 photo will do, really. Yes, there were fat people back then, but they were rare.)
Sorry. But I think I missed part of your post. Didn’t see what help you were suggesting.
Exercise was suggested because you said you were going underweight - maybe keto, lots of sleep, no stress etc. (what most of us need and do not have) was actually “helping” you a little too much.
You say you are active but, is it enough to ever create a muscle adaptation response?
It seems like just changing what you put in your coffee may not be enough - maybe you need to create a demand and have your body address it to balance out some things.
Just ideas - not a doctor or really knowledgeable about what to do when weight gain might be part of the issue (unfortunately always working the weight loss issue myself).
Great post Martha. You listed some things you tried and your observations. That kind of post can be helpful to others to solve issues or even to realise things they haven’t noticed.
Carry on. 
Contrary to popular keto belief, eating more fat isn’t the answer to EVERY problem. It CAN be if that’s the problem, but unless you’re under eating fat, that’s probably not the issue. Why are you afraid of protein or carbs (within reason) if you’re having issues keeping weight on? How much are you eating daily? Are you tracking your intake or eating intuitively?
I agree with what others have suggested - increase your protein (Dr. Bikman says up to 200 g/day) and if that doesn’t do it, try a 50g carb/day limit. You may need more carbs. Everyone is different.
Just eating when I’m hungry. Don’t track anymore. Trying to become more “normal” in my relationship with food. Reluctance to eat more protein or carbs comes from desire to stay in ketosis so I don’t start regaining all the weight I lost. No carbs, no insulin, no weight gain.
I guess I feel more comfortable with doing more fats because I have read that eating more fats than you need will just cause your body to activate the heat producing fat burning cells and that is what I am trying to do. Yes, eating carbs does make me run hotter but it will also trigger insulin which could cause me to start storing fat again and that is NOT what I want. I lost 100 lbs and hope to never have to try to lose weight again.
Just means doing something that will build muscle. Walking, jogging, dancing etc. use muscles but do not use them hard enough to make them become very much stronger (but you would still be considered active). Push ups, pull ups, planks etc. basically just about anything that burns a bit (like sprinting vs. jogging) will cause muscle adaptation (added strength).
I am thinking that if you just add protein for example, that might not help you keep weight on as much as adding protein and muscle adaptation type exercise.
