I don’t think the training part is much of an issue… If you have some time during your lunch break every day, you can train 5-6 days a week… Either pick 1 exercise per muscle group and split the body 2 ways or so… Or split it up 5-6 ways and do 2-3 exercises per muscle-group… Or 3 ways and 1-2 exercises per group…
Sessions shouldn’t take much longer than 30 or so mins then, depending.
If you have fewer days, but perhaps more time per session, then just train more muscle-groups in a single session…
The diet is probably going to be more of an issue, but that can be fixed… Shakes (with added fiber like metamucil or benefiber) at work for convenience, always keep some powder in the car in some plastic shaker bottle or so, and some water… Use that if you get stuck in traffic/at work or something else comes up, preventing you from following your regular meal-schedule…
As for solid meals, that’s do-able too… If you’re married, your wife can help.
Buy a vaccum sealer machine (Professor X wrote about those before, search for those posts if you don’t know which one to buy or whatever) and a foreman grill.
Use Sundays or Saturdays for food-prep for the week.
Get an extra large fridge and buy meat etc in bulk once a week.
Other than that, pick a couple of different “filler” foods which have a good amount of cals and of which you can eat a lot easily (note: Not cake and shit like that. Pizza can work though… I like Mozarella cheese, among other things).
Make sure you have a general idea of how many cals/what macro ratios there are in your chosen foods…
Now combine them into meals depending on your needs and time… Make sure you pick foods that don’t take forever to prepare and which suit your budget.
I organize mine into protein+carb and protein+fat meals. Some mixing of fat and carbs can’t be avoided of course, and I don’t always go super-strict when not dieting, but yeah…
-Could make that Spaghetti with a big protein shake (and some fish oil caps for me on all the big carb meals)… (protein+carbs)
-Mozarella cheese+tomatoes+seasoning+olive oil in a cup… (protein+fat)
-Avocado + Cottage Cheese or a Shake or whatever (protein+fat)
-Pizza Salami (a mix of all three, probably more carbs than the rest, but if you need the cals… As long as it’s not a shugar bomb, I’m usually fine)
-Rice, seasoning, lean cut of Steak (protein+carbs, but Rice can be hard to get down in greater quantities… Imo a lot of clean foods are like that… Chicken breasts and rice aren’t that great if you have a very fast metabolism and want to gain weight…)#
-Boiled potatoes + lean meat/fish
-Boiled potatoes + low fat curd/quark
-non-lean cut of Steak or Fish or whatever + some additional fat source perhaps.
(note: additional vegetables wherever/whenever you want to add them)
The last 3-4 hours before bed or so I’ll go with lean protein sources and some salad etc, fiber…
And so on, I’m not exactly a gourmet… Other people will prefer different foods.
For your favorite restaurants etc (if you eat there a lot vs. at home), find out what the macro ratios/cals are (roughly) just so you have some idea and can choose what fits your meal plan.
There are some more convenient foods for people on a tight schedule and who need to get the cals in… Example would be : Oatmeal in a blender, turn it into powder and add to your shakes for added carbs. Easy to drink down… If you have fiber supps in there, then it may turn into pudding after a while though, so yeah…
Anyway, think of the solution and not the problem… It may seem difficult/a lot of effort (boo-hoo) to get in all the food you need, but you just need to come up with some work-arounds for that… Once you have those, things will be easy enough.
If you don’t like eating the same stuff every day, just do what I wrote about above: Pick a variety of protein/carb/fat sources which fit into your budget/situation and are quick enough to prepare or can be prepared in advance and vacuum-sealed and then mix and match.
