Cruciferous vegetables are a unique group of vegetables that contain particular phytonutrients that promote good health. The group consists of vegetables like broccoli, cauliflower, cabbage, Brussels sprouts, mustard greens, bok choy, radishes and arugula, just to name a few. Cruciferous vegetables are one of the best types of food you can eat when you are trying to lose fat.
Cruciferous vegetables contain few calories. Reducing the number of calories you eat is crucial when you are trying to lose fat. If you eat more calories than your body needs, you will gain fat no matter where the calories come from. One cup of chopped broccoli, for example, only contains 41 calories. You could eat 10 cups of chopped broccoli and only consume 410 calories -- less than 25 percent of your daily caloric needs based on a 2,000-calorie diet.
Cruciferous vegetables are high in fiber. This is good for fat loss because high-fiber foods fill you up quicker and leave you feeling full for longer amounts of time. They also improve your digestion and aid in the process of removing waste from your body. High-fiber foods have a lower glycemic index, which means they don't cause spikes in your blood sugar that lead to the release of insulin -- the chemical in your body that converts calories to fat.
Cruciferous vegetables are mostly water, so when you eat them, you are adding more water to your diet and hydrating yourself. According to bodybuilder John Giljum, your muscles are 73 percent water. The more hydrated you are, the more your muscles weigh, which increases your metabolism and helps you burn more calories.
According to Ori Hofmekler, author of "The Warrior Diet," an imbalance in estrogen metabolism can cause your body to store more fat. Furthermore, it can also lead to estrogen-related diseases, such as breast cancer. An imbalance in estrogen metabolism is commonly associated with a diet low in vegetables. Cruciferous vegetables contain a large amount of diindolymethane, a compound that can restore the balance of your estrogen metabolites.
