In one sentence, describe what the following article is about: Focus on whole foods rather than on "diet foods." Low-calorie condiments will help you to reduce your calorie intake, and low-sodium condiments will keep you from retaining water.
Summary: Avoid saturated fat, which is found in some animal products, in egg yolks and in full-fat dairy, as well as trans fats, which are found in foods containing hydrogenated oil. Do not rely on reduced-fat, sugar-free, fat-free and low-carb products that have been highly processed. Make use of spices and herbs, which pack flavor into meals without added calories or sodium. Choose condiments that are low in calories and sodium.

In one sentence, describe what the following article is about: Facebook doesn't charge for video calls, but if you're on a cellular data connection they will count against your data plan. Using Messenger while connected to a wireless network will mean you can place and receive all the calls you want without worrying about data usage. You can only chat with a single person at a time, so the video button will not be available in group chats. Start a conversation with a single recipient to see the video button. Video calls are placed just like phone calls. You'll see a small window displaying how you appear, and the recipient's video will take up the main screen. If the video button is grayed-out, the other person cannot receive video calls. They may be offline or may not have Messenger updated to the latest version. The other person will be able to see you a lot easier if you are in a well-lit room or outside. Direct sunlight may not work well with your device's camera. Hold your phone out and away so that the other person can get a good look at your whole face. This will switch between your device's front and rear-facing cameras. Use this to show the other person something through the video chat. This will stop your phone from transferring audio in the call. Tap it again to unmute your audio. This will continue the call as an audio call for the other person until you turn your camera back on by tapping the button again. This will allow you to access your phone while the chat is ongoing. Your camera will stop recording while the conversation is minimized, and you can tap the bar to return to the conversation.
Summary: Connect to a wireless network, if possible. Open a Messenger conversation with the person you want to video chat with. Tap the "Video" button to place a video call. Make your call from a well-lit area and hold the phone away from your face. Tap the camera button in the upper-right corner during a call to switch cameras. Tap the microphone button to mute your audio. Tap the camcorder button to turn off your camera. Tap the two arrow button at the bottom to minimize the chat (Android only).

In one sentence, describe what the following article is about: Distributing the weight so that the lightest items are at the bottom, he heaviest items are centered between your shoulder blades and the medium items are stashed around them is the best way to keep your back healthy. If you pack the heavy items first, you'll be putting a lot more strain on your back. Packing the heavier items right along your upper spine situates the weight of the pack on your hips, rather than in a place where it would cause injury. If you're camping overnight, pack your sleeping bag and other light sleep-related items first. On top of those, pack your changes of clothing, extra socks, extra gloves and so on. Pack the heaviest items: your water, your flashlight, your heavy cooking supplies and so on. These should be centered between your shoulder blades right up against your back. Then pack medium-weight cooking supplies, food supplies, your first aid kit, and other medium-weight items so that they surround the other items and stabilize your pack. Wrap flexible items like tarps or clothing around the heavier times to keep them from shifting as you walk. There are a few items that you'll need to have handy, so even if they're light, they should go on top or in the outer pockets. You'll want food and water handy, as well as your map, GPS, flashlight, and a few first aid items you anticipate needing. Pack these items carefully so you know just where they are when you need them. After a few days on the trail, you'll get a better sense of what you need to be accessible and what you don't. Rearrange your pack as you go so that it's packed to be as convenient and comfortable as possible. If the gear you have won't fit in your backpack, you can attach it externally by strapping it to the top, bottom or sides of your pack. For example, you might want to attach your tent poles to the top of your backpack, or hang your water bottle from the side. If you choose to attach items externally, there are a few things to keep in mind: Attach as few external items as possible. It's better to pack everything you can, since as you hike you'll end up catching your gear against trees and other obstructions. Keeping it contained makes for a more comfortable walk. Follow the rules for weight distribution. For example, attach your heavy tent or walking poles to the top of the pack, not the bottom. Lift the pack onto your body and tighten the compression straps to a comfortable position. Walk around to see how it feels when you carry the pack. If you can walk around comfortable, and the pack feels compressed and secure, you're good to go. If you feel things shifting around, remove the backpack and repack the items so they're more compressed and stable, then try again. If the backpack feels tippy, remove it and repack it so the heavier items are centered between your shoulder blades right against your spine. They were probably too high in the pack before. If it feels off balance, repack it and try to distribute the weight more evenly on either side. If it's way too heavy, think about what you can leave behind. If you're walking with a group, see if someone else has room to bear some of your load.
Summary:
Pack the lightest items at the bottom and the heaviest close to your back. Keep essential items immediately accessible. Attach external items. Check the pack to see how it feels.
