Why Eat Vegetables for Weight Loss?
{{mid-cta}}
One of the keys to weight loss and maintaining weight loss is eating fewer calories. Research has consistently shown that people who eat a high-calorie or energy-dense diet are heavier than those who eat more nutrient-dense foods that are lower in calories and filling.1,2,3
You know that most veggies are low in calories, making them one of the best tools for weight loss. But they help with so much more than that. They are also filled with fiber and nutrients that support your metabolic health.
Most vegetables are also low in the glycemic index, and their fiber content helps slow the absorption of sugar, keeping your blood sugar more stable.
Filling half your plate with vegetables or snacking on them for a snack are easy ways to decrease the calories you eat while filling you up and satisfying your cravings, so you are raiding the vending machine or hitting the drive-through on your way home.

Tips and Tricks to Eat More Vegetables
Adding more vegetables to your diet shouldn’t be stressful. There are easy ways to get a few more in throughout the day with some tricks.
Filling Half Your Plate With Vegetables
One of the easiest ways to ensure you get some extra vegetables in is to fill half of your plate with them. Divide your plate into quarters. One quarter for protein, one for whole grain starch, and the rest can be filled with vegetables. Low on time? Sauteed vegetables and stir-fries are easy preparation methods that can transform raw vegetables.
Add Vegetables to Breakfast
Sure, it's easy to add vegetables to dinner and even lunch, but have you ever thought to add them to your breakfast, too? Toss some leafy greens into your morning smoothie, chop some peppers and spinach, and mix them into an omelet.
You’ll get your day off to a great start and get some extra veggies in immediately.
Enjoy Them as Part of a Snack
Just like adding vegetables to your breakfast, you can also include them as an afternoon snack. Plus, they will fill you up, helping to reduce cravings and keeping you satisfied until dinner.
Add Them to Smoothies
One of the easiest ways to boost your veggies is to add them to smoothies. Avocados add a creamy texture to a fruit smoothie, and baby spinach, kale, and even parsley can be tossed into a green smoothie that you can enjoy on your way to work or as you get caught up on your morning email.
Add Them to Your Soup
Soups can be an excellent vehicle for getting more vegetables in. Firmer vegetables like carrots, cabbage, and green beans hold up well to cooking in soups, plus the vitamins that leach out of the vegetables stay in the broth, so you are still getting all the nutritional benefits from them. You can also toss dark leafy green vegetables in at the end of the cooking to add some extra bulk and nutrient-rich veggies into your meal.
Mix Them Into Ground Meat, Sauces, Pasta Dishes, and Casseroles
Mushrooms and carrots are easy to chop up and mix into ground meat, sauces, and casseroles. They can replace ground beef in these dishes or add bulk to the sauce or casserole. Cauliflower and zucchini can replace rice or pasta in some meals, cutting back on calories and fat. Rice the cauliflower by shredding it in your food processor and then use it like rice; run a zucchini through a spiralizer; or cut long thin strips and use it instead of spaghetti.
There are many ways to add vegetables to your daily routine. If it seems overwhelming, start slowly and add one more serving to your day. Even one extra serving can add many health benefits and help with weight loss and blood sugar control.
