It's gotten long over the months.
It really started as me just ranting about some things though... it wasn't meant to be a Q&A.
But it's fine that people ask questions here.
What were you doing that made your diet unhealthy when you lost weight the last time?
Admittedly I haven't read the biggest loser stuff, so I can't comment on that. Biggest Loser is about calories and getting enough calories by eating healthy less processed food in a healthy diet. In a nut shell 4 veggies or fruit (but more veg then Fruit) 3protein, 2 starches (whole grains not enriched not sure why but I like them so it doesn't matter), 1 fats and oils.
I was eating nothing but fruit and 1 lean Quicine a day. I kept fat grams down to 10 - 15 a day. I rarely ate meat or starches. and I hit the treadmill 3 to 4 times a day for 20 minutes a time and walked 2 miles a day with a neighbor.
First let me say I'm a fan of breakfast. Not only b/c I'm hungry as all hell when I wake up, lol, but I think it's a good thing to fuel your body up after the evening 'fast.'
That said however, I don't see any real issues with you waiting to eat assuming:
1. You're getting adequate protein in your diet
2. You're able to get in adequate energy even though you're starting late
3. The lack of food in the A.M. doesn't lead to binges in the PM
I am not hungry in the morning but I force myself to at least drink a cup of milk (skin for calorie sake) so that I don't get hungry early. If I miss that i have hunger pain around 10:30 and I will grab milk then and be okay.
Your husband needs to do things that are going to contribute best to expending energy (calories). Traditional weight lifting probably isn't going to be the best.
First, his primary point of concern/focus should be nutrition. You can't out exercise a bad diet, especially when you're over 400 lbs.
I can't stress that enough.
But I'd start him with primarily cardiovascular activities. I'm not sure of his endurance/capabilities, but maybe he could start with splitting up each session into 2-3 more tolerable bouts.
It doesn't really matter what form this cardiovascular exercise comes in, I'd just make sure it's nothing that has high impactive forces associated like running. No worries there.
Walking, swimming, bike, high rep-low rest weight lifting, etc, etc.
