We have been going 16:8 with Keto (low carb) for 10 days now. I’ve already lost 4lbs. Wife has been getting some headaches but otherwise she is good. We switched to espresso in the morning and drink a ton of water. Fast is 8pm to Noon. At noon we allow ourselves propel and some coffee with sugar free creamer but not a ton. I really like this “plan” feel much better. Good luck
How much health? How much more energy? Do you need more energy so something specific? I would definitely chase a specific goal, it will help hold yourself accountable, once you reach that goal, set another one! Your success is your best motivator to your spouse. You can only control yourself anyway, they need their own goals for it to stick!
Good luck IM is a great tool.
I’d consider trying to cut simply white starch carbs rather than carbs altogether…….. whole foods tend to digest slower and are of course more nutrient dense……… (roasted root veggies with balsamic are a staple chez moi !).
