Any good advice or tips for a frequent business traveler?

I used to travel on average 20-25 days/mo and still travel at least 5-7. My tips:
For the Flight/Car: STAY HYDRATED- drink tons of water. Avoid the urge to eat out of boredom, or if you know you will, bring healthy snacks- protein shakes, cut fruit/veggies, beef/turkey jerky
In Airports: Research your restaurant options ahead of time. Figure out your gates, the path between them, and whether this is a meal time. Figure out where and what you're going to eat before the plane ever takes off
In Hotels: force yourself to get up and hit the treadmill every morning. If you're a west coaster travelling east, this is going to suck. Do it anyway. If you're on the east coast headed west, your body will want to be up at 5am anyway, go with it and hit the gym. Bring protein powder and a shaker bottle with you, drink this instead of whatever carb/fat loaded breakfast is provided for you
Meals (especially with clients): This is all about moderation and good choices- gin & tonic is better than beer if you can hold your liquor. I can't, so I choose champagnes, wine, or light beers. Lean toward vegetables & lean meats. I avoid pastas, breads, anything "Crispy" "Battered" "Fried" or "Coated". I always order my dressing on the side, I never eat fried carbohydrates (always sub the veggies), and I'm mindful of my condiments.
Meals by yourself: RESEARCH. Look up options near your hotel/office/site ahead of time, bookmark them on yelp, find out if they deliver, etc.

Given all of this, I'm usually still over 200-300 calories a day if I eat more than one meal with a client or on site. However, that number is manageable for me. Its really scary how much added butter, sugar, and oil is in most restaurant food. I have found that most supervisors won't complain about your expense spending if you explain that you chose the healthy option over cheap crap. They know they're already inconveniencing you with travel, they're not going to force you to eat like crap as well.

The struggle is real I get it. I started a similar post to this a while back. I travel every second week for 5 days mon-fri.

All the advice I've received is simply not doable all the time. Some days I am in meetings and working from 7 am to 9 pm and all of my meals are meetings and eating out.

I'm only 48 days in of trying to figure this out myself...but so far this is what I've changed to try and make it work because I gained almost 30 lbs over the last 3-4 yrs.

1. Stopped booking breakfast meetings. If someone wants to meet that early I tell them in advance that I'm on a health and fitness plan and cannot sustain eating out every meal. It felt weird at first to say this but what I quickly realized is that they felt the same way and completely understood! So instead I would have something I packed. Protein bars, almonds, protein drink, whatever works for you. Even just eggs and toast at the hotel restaurant.

2. When im in back to back meetings all day every day for days on end I end up drinking WAY too much coffee. When you add up all those coffees it's a bunch of wasted calories. I started only drinking water or nothing at all during meetings.

3. I started packing snacks for travel time. For on flights, in the car between meetings, in the evening im my hotel room when I'm sending all those emails to the people I made promises to throughout the day. This helps prevent me from overeating when it is meal time because I'm starving.

4. Always pack plenty of gym clothes so that I feel good and can put something clean on every time. I don't force myself to go to the gym every night. Some nights I'm way too exhausted because it was a 12-14 hour work day of rushing from meeting to meeting. However I try and get there at least twice in that 5 day period.

5. I spend a lot of time and effort ahead of time trying to strategically book meetings that are walking distance to each other. This is impossible a lot of the time...but here and there it is. And I just do it as much as possible to try and walk as much as I can. I also take stairs every time, never elevators. This forced me to buy a backpack laptop bag instead of a shoulder one. It has saved my life lol.

6. I know this sounds weird and can't be done all the time I understand. But I've tried it twice now and it worked! I requested that two of my meetings be "walking" meetings last week while I was away. Surprisingly the response was that's a great idea! One of the days it was raining so we had to walk around inside the pedways but that was almost better because it was quieter.

7. When I do eat out at restaurants, I used to feel odd ordering something so specific but I just had to get over myself and do it because i was tired of gaining weight every second week. To my surprise servers and restaurants have been very accommodating. Many times I get "are you tracking your macros?" And I say yes, yes I am lol. I ask for their help In tracking down the nutritional info for their menu (it's usually on their website) and make the best choice possible. This one took me a long time to do. I had it in my head I was being a pain or that I was taking Away from the meeting by spending time on being high maintenance rather than building rapport with my client or associate. I'm totally over it now though. I've come to realize that people respond well and respect me making healthy choices and it's not an issue at all. I ask for half my meal on the plate and half In a to go container if it's a lot of food and always ask for sauces etc on the side. Surprisingly those are the things packed with calories, not so much the actual food.

8. I Strive to hit the 10,000 steps a day. Which means if I'm waiting in the lobby for my taxi...I'm walking around the lobby as I wait, not just standing there.

9. I am doing my best to stop booking meetings so late and making sure I have time to do my emails in the evening and still get to bed at a decent time so that I'm getting enough sleep and proper rest. I put this before going to the gym.

So far these things have helped me. I've still managed to lose 8.7 lbs in the last 7-8 weeks even when travelling. It has been a total shift in my thinking and taking my power back. As for the drinking I still have wine here and there at dinner meetings but I just cut back as much as I can.

It's all about finding a solution for all the individual challenges and making it routine. Instead Of being powerless and making excuses or justifying why it's so challenging. And the reality is others solutions don't work for me (like go grocery shopping once I'm there and don't eat out, like yah right lol). So some of my solutions may not work for you. Like the walking meeting. That's only doable once in a while cause I'm usually doing a walk through of a presentation on my laptop. But each trip you will find one more way to make it better and over time you'll have solutions and routines you can feel good about. A bunch of tiny little tweaks will add up, trust me.
