Already try one meal a day? Easy to do once you're keto-adapted. You want at least a pound of protein most days, with lots of saturated fat, and a big side of greens, veggies etc. Eggs are in, and duck, lamb, heart, fish, liver, etc. I do that for eight days in a row, every other week, and it feels amazing. I have energy while burning fat. Try to get lots of medium chain triglycerides, too! Helps the mood and energy.
Took my body over a month to figure out how do digest and use fat. I have done this 1 year and lost 20 pounds. Relax. Take it easy. You don't have that much weight to lose, so your body is just taking its time. Definitely focus on getting that daily PROTEIN. Made all the difference for me.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
