Hi I'm new, I had quite a lot of weight to loose and so far about 80 lbs are now history. I've been doing keto and rode heavily during the summer. Your body eventually adapts to it. I took potassium and magnesium and added fresh cranberries and walnuts to my salad. It kept me in the keto range and minimized the cramping on hills. We live in a rural and fairly remote by US standards where it's about half paved and half dirt and a few roads that don't really qualify as roads. It's hilly, big hills or small mountains. I ditched the potassium and magnesium after I found the dietary adjustments. I avoid leafy greens unless they're frozen or I raise them myself because of contamination issues. So that means that I don't eat them at all during winter. I use broccoli, peppers, and Swiss chard that I grow myself. Winter I'm limited to cabbage onions, and frozen broccoli and spinach ( if I can find it) I do fresh tomatoes in September as we have a limited time when they're in season and I cannot resist going to the farm and smelling those things and not eating a few.

For the weight loss I eat a solid breakfast and use pork belly instead of cured bacon, eggs, I have salad of raw vegetables of whatever is handy, usually broccoili based with an oil dressing at lunch I make my dressings I don't use store bought. I don't usually have any meat for lunch it's just veggies. Supper is early and I have a meat and veggies. Only snack is early evening and that's a couple boiled eggs. I don't use butter,creme or sour creme and only about an ounce or so of cheese a day max.

For me the keto was a good solution. The process of adaptation may take a year or so. Be patient work on distance and interval.
