Hello! I just started on a ketogenic diet 4 days ago...so would love to chat with some folks that are more experienced! I started mainly due to some low cognitive functions - poor memory, bad mood, increased dyslexia, ect & needed a good brain diet but am also very interested in ketosis for weight loss as I could go down 40-60 lbs. Besides high weight and poor brain functions I am an otherwise happy and healthy woman in my late 20s that enjoys bicycling, hiking, playing with my pup... Since starting the diet I have noticed a very marked increase in energy, memory and better mood already. Just today was my first time experiencing a distaste for the diet....so.much.fat. I really wanted some toast, noodles, white potatoes....spring rolls with rice noodles...whatever carb I could get my hands on (all of which exist within my house....roommates make the out of sight/out of mind thing impossible) I did eat one newman O cookie (10g carbs) And it was the first time I experienced hunger on this diet so far...every other day I've felt completely content eating extremely high fat & low carb. I'm wondering the best/healthiest way to approach this. A little more protein? More vitamins? More veggies? I also tried Stevia extract for the first time - a few drops in my coffee this morning....perhaps that is the source of the sudden cravings & I should skip any sugar subs.
Well I appreciate this forum! & thank anyone that takes the time to read/respond/offer advice!
