The way diet experts have demonized fat, it's tough to believe you may not be eating enough of it. "One of the biggest mistakes people make is ignoring good fats," says Alyson Brown, a nutritional therapy practitioner in the San Francisco Bay Area and founder of Wooden Spoon Nutrition. "Butter from grass-fed cows, avocados, coconut oil, and omega-3s from fish, nuts, and seeds provide healthy fats that are longer-burning fuel than the carbs in grains and starches."
Adding healthy fats is simple, she says. Just throw an avocado into a salad, or eat a piece of fruit with almond butter for a satisfying snack. When we ignore fats, we start hungering for fast fuel sources, leading to cravings for carbs. "Also, walkers will appreciate that fats are the precursors to anti-inflammatory hormones," says Brown. "That can help protect your feet, knees, hips, and joints."
When you're trying to lose weight, your snacks should be satisfying and low calorie, usually around 100 to 200 calories, says Bainbridge. When you walk for less than 90 minutes, you probably don't need a snack as much as you need to stay hydrated. Going longer than that? Tote along a piece of fruit, some nuts, or a low-fat cheese stick. "You want to make sure you're snacking on real, whole foods that are satisfying and slow burning," says Bainbridge. "It's easy to eat too many calories when you eat a granola or energy bar. Plus, they're usually filled with sugars that will leave you hungry."

3. You choose rewards unwisely.
Starting in childhood, we learn to use food as a reward. Cupcakes, candy, and cookies were used to celebrate achievements. As you start to walk and to drop pounds, it's important to reset your expectations. "When you start to walk, don't think, I'll walk for an hour and then reward myself at the pastry shop. Instead, walk to a magazine shop, or walk to enjoy your favorite songs or podcast, or to enjoy the scent of an Estée Lauder sunscreen that you bought as an indulgence," says Bainbridge. "It's very important to find motivation to walk that isn't a high-calorie treat."
Staying hydrated is one of the keys to weight loss and healthy living. "When you're not hydrated properly, you have less energy and the body confuses hunger with thirst," says Brown. Water is especially helpful when walking because it lubricates joints and cools you as your body temperature climbs. "Water is the highway for transporting nutrients," says Brown. "Without enough water, nutrients aren't going where they need to go. That's when you start to feel hungry, even though you're not." She recommends drinking pure water, but if you need more taste or some electrolytes, try adding cucumber slices, mint, or lemon to your water. (Here are 25 slimming sassy water recipes to try.) Or try coconut water or sparkling water. "Just avoid hydrating with a sugary sports drink," says Bainbridge. (You can tell how hydrated you are by checking your pee; here's what the color of your pee says about your health.)
6. Your fridge and pantry have it in for you.
Log the recommended 10,000 steps—about the equivalent of 5 miles—and you'll be feeling pretty good about yourself. But that good feeling can turn sour if you double down on dessert or feel like you deserve a treat. "Frequently, people start to walk and they feel good, so they think it's OK to have wine and cheese in the evening and some ice cream after dinner," says Bainbridge. "That's why it's so important to fill your food environment with only healthy options." Willpower is weakest late in the day. If you haven't eliminated junk and high-calorie foods from your home, you'll reach for them and sabotage any gains you made walking.
