Start the week before your trip and avoid last minute trips and anxiety
Try to have an idea of what each day will look like: Am I on the plane or road? Am I visiting someone? Am I visiting something? (park, monument, etc) Research before going.
Day Time Tips- if you're unsure about what the day will look like:
Bring a water bottle
Bring portable snacks (jerky/protein bar)
Pack Vitamins
If fast food is the only option do your best. Remove the starch and focus on the protein/veggies.
Air Travel
Should you eat before arriving? Look up what food options are available at the airport.
Purchase a large bottle of water or make sure to refill a personal bottle after security.
If eating in flight, choose the meat option. The vegetarian option is typically pasta.
Avoid grazing. If snacks are needed, pack in your purse or carry-on.
Pack non-perishable, non-liquid food items you can't live without and can't purchase at your destination. Like: protein bars, protein powder, jerky, reusable water bottle, high protein oatmeal, vitamins, drink flavorings, decaf tea/coffee.
Consider: is there a kitchen at the hotel? Need small kitchen utensils? Need portable blender? Need camping stove?
Road Trip
Are you going to allow eating in the car? If not, are there rest/picnic areas along the way to stop and eat?
Use an ice chest to pack: perishable foods you can't do without, meds, vitamins, fluids. Use electric or heavy duty versions to keep ice from melting.
Avoid grazing out of boredom.
Have a plan for bathroom breaks. Don't pick up last minute snacks.
Snack ideas: Deli meat, cheese slices, protein shakes (pre-mixed), protein bars, veggies, yogurt, jerky, tuna packets, canned chicken, protein chips, consider prepped meals if driving through day/night, desired fluids and flavorings.
Use microwaves at gas stations
At Your Destination
Look around for a grocery store to buy any products you need.
Consider booking a hotel near a grocery/convenience store or use grocery delivery apps.
Utilize your kitchen if you have one.
Try to apply the same rules at home when dining out:
Research local restaurants,
Order to-go
if possible,
Make reservations,
consider outdoor seating if possible.
Back at Home
Go back to your regular pattern of eating
No need to "crash diet" or "detox"
Hydrate
Before your trip, consider cooking and freezing a few meals for the first few days back home
