The background: My husband has had great success with keto (down 25 lbs so far), but I'm struggling with my own diet in the process. I don't want to go keto myself because I'm a distance runner. But logging my meals for the last two weeks, I'm eating around 40% fat. I gained 10 lbs last half-marathon season and didn't make the speed gains I hoped for. I'd like my macros to be around 40/30/30 for the off-season but I'm struggling to incorporate low-fat proteins. We also have a small child and I want to make sure he's eating a healthy variety of foods too.
The question: has anyone had success managing two separate diets in a household? Did you find it to be very expensive (it has been for us to buy smaller quantities and different types of food for each of us). Any advice?
