Im not on keto and purposely stay out of it. I find the draw backs. Mainly the smell to bad to get on with.
At 75g I'm not really cutting a whole macronutrient out. Im just selecting low carb veg with higher nutritional content.
The reason i do it is a few fold.
Yes i do find it massively easier to stick with, i don't sit felling hungry all day. It basically cuts out all the physical symptoms, obviously the psychological issues are still there. Comfort eating or for me, i enjoy cooking and do it when I'm bored. Bored a lot. Job doesn't help, lots of days, not many hours.
Doing it to lose weight, and its one of the things which work and can stay with it. Things like the conventional advice, yeah i lose weight, but low fat high carb, just makes me sleep all day. Where this I can easily go do a 10hour walk and have to force myself to eat more, i have done it whilst consuming just water and had no ii'll effect or need. Not that i think thats a good idea. Tend to carry lots of dried berries and nuts. Need to start dabbling in home made protein bars. That night/next day you can tell the body is crying out and food intake increase a fair bit. As it repairs itself.
When I reach my target, then i will increase carbs, but it'll stay be far lower than the recommended. Basically fat/protein will stay the same, but ill start eating sweet potato and other such roots, instead of swede or cauliflower puree etc. to a point that it maintains the weight. And I'm still reading what ever i can get my hands on and then if its referencing, reading the actual study as a lot of places don't share the whole conclusion. Or pick apart how the study was run. Both of which can drastically change their conclusion.
Current advice is crap as well as current research. Read so many clinical trials that compare tow diets, but have no idea what they're doing and using food usually banned from such diets. The best ones are low carb, yet the studies often use processed food, veg oils etc. where if you look at paleo and others, its all about whole foods and going back several thousand years before all the processed stuff.
Plenty of protein (fish, seafood, meat inc offal). Plenty of natural unrefined fats, plenty of veg and some unrefined carbs.
