Many of the personal training and bootcamp ladies that I train, frequently ask me about what to do about cooking for the whole family.
When you start a new nutrition plan and your family isn't on that plan, there can be some ruffled feathers about what's going on at the dinner table. But it really doesn't have to be that way. Most of the time you can prepare meals that the whole family will like, without causing turmoil and wiping out your nutrition efforts.
When you prepare a good meal, the easy fix is for you to simply adjust the macronutrient ratio of your plate regardless of what other family members are doing. Of course you want to encourage your family to follow your lead but you have to deal with people on a case by case basis.
Normally the big issue is dealing with the starchy carbs like the mashed potatoes and gravy or the mac-n-cheese and cornbread type situations. The normal problem is that people eat a ton of mashed potatoes and gravy and a little meat and too few vegetables. You can fix your plate with a meal like this by simply having mostly meat and vegetables and going easy - (real easy) on the mashed potatoes.
Whether or not you can wean your family off the starches and put more veggies in there will be your challenge. But you do have control of your plate and fork. So eat more the the good stuff and less of the starchy stuff and that will be a big step forward in maintaining sanity at the dinner table. The rest of it will have to come with time and perseverance.
