5. Meat (Pasture-Raised and Free-Range)
Grass-fed beef, chicken, and pork is leaner and healthier than conventional livestock—and will help trim away pounds. A 3.5-ounce serving of grass-fed beef has only 2.4 grams of fat, compared with 16.3 grams for conventionally raised beef. In fact, grass-fed beef is so much more nutritious than commodity beef that it’s almost a different food.
Grass-fed beef contains more conjugated linoleic acid (CLA), which has been shown to reduce abdominal fat while building lean muscle. It also has more omega-3s and less omega-6s than corn-fed beef. It ‘s the same with chickens. According to a recent study in the journal Poultry Science, free-range chickens have significantly more omega-3s than grain-fed chickens, less harmful fat, and fewer calories than grain-fed varieties. This is important because omega-3s improve your mood, boost your metabolism, sharpen your brain, and help you lose weight.
