8 weight-loss tips you can incorporate into your diet that actually work

That bag of chips you polished off last night is not just full of empty calories (six chips can have over 100 calories) — it's also a salt trap. Dr. Taz said that salt, like sugar, can affect insulin resistance and cause weight gain, high blood pressure, migraines, and more.

Fat is not the enemy — rather, it's certain types of fat that causes problems. Research shows how the right balance of fat can actually prevent us from overeating, as Dr Taz points out. That's why you should drop the trans fat, go light on the saturated fats, and instead, opt for monounsaturated and polyunsaturated fats.

Good sources of monounsaturated fat include olive oil and avocados, and sources of polyunsaturated fats (omega-3 fatty acids and omega-6 fatty acids) include salmon and flaxseeds.

It's Monday morning and you're running late. You open the fridge to grab something quick to pack for lunch and realize there's nothing ready to go, so you settle for buying lunch yet again. Does this sound familiar?

"You wouldn't go to work unprepared, so don't start your food week unprepared," said Dr. Taz. She recommends having lots of healthy options in your fridge and pantry, lunches ready, and dinners prepped. Weight loss is a lot easier if you eliminate the common traps that lead to poor nutrition.

Healthy eating has to fit into your life, or you will never be able to maintain it. "While veggies should fill up our plates, it is not realistic to say that you will never eat cake and ice cream or chips and queso again, so it is important to understand how to make all foods fit," Registered dietitian Amy Goodson, MS, RD, CSSD, told Business Insider. That's why she recommends living by the 80/20 Rule.

"This means that 80 percent of the time you focus on eating nutrient-rich foods like whole grains, lean protein, healthy fat, fruits, and veggies as well as exercising," she said. Then, 20 percent of the time you can include foods that are higher in calories and lower in nutrients. "You know, the ones that taste so good, but that you shouldn't consume every day for your waistline and health's sake.

"If you skip meals, you set yourself up to feel starving, and likely to make less optimal food choices," Goodson said. The goal is to fuel your body with nutrient-rich foods every few hours throughout the day.

"Eating regularly helps stabilize your blood sugar, and thus your energy levels, as well as help you feel hungry and satisfied versus starving and stuffed," she said.

"With plates and portion sizes being so much bigger these days, your goal should be to think of eating until you are not hungry, instead of until you are full," said Goodson.

While this is easier said than done, Goodson said pre-plating your food, portioning snacks into baggies, and asking for a to-go container at the restaurant can help you maintain better portion control. "A good rule of thumb is to take your plate and make half of it veggies, one-fourth lean protein and one-fourth whole grains; then if you are hungry, go back for more veggies," she explained.

Protein helps slow down digestion, which means it makes you full faster and helps you stay full longer. "Pairing protein with a carbohydrate at each meal and snack will help stabilize your blood sugar and energy," said Goodson. The Academy of Nutrition and Dietetics recommends 1.2 to 2.0 grams of protein per kilogram of body weight per day for athletes and 0.8 grams of protein per kilogram of body weight for general health.
