Gastrointestinal disorders are another common cause of unexplained weight loss – in fact they are the most common non-cancerous cause of idiopathic weight loss. Possible gastrointestinal etiologies of unexplained weight loss include: celiac disease, peptic ulcer disease, inflammatory bowel disease (crohn's disease and ulcerative colitis), pancreatitis, gastritis, diarrhea and many other GI conditions.
4. Meditate daily: A study from the University of California, San Francisco found that meditating for just 30 minutes a day can reduce belly fat by way of reducing stress levels (remember that cortisol/fat connection). Plus, a regular mindfulness or meditation practice can help you eat less calories overall and cave less to cravings and emotional eating (and all those processed ingredients that wreak havoc on your fat-regulating hormones).
Whether you sit or stand at work may play as big a role in your waistline as your fitness routine. Missouri University researchers discovered that inactivity (4 hours or more) causes a near shut- down of an enzyme that controls fat and cholesterol metabolism. To keep this enzyme active and increase your fat-burning, break up long periods of downtime by standing up—for example, while talking on the phone.
Set up a box behind you and then lower your body until your glutes touch it. Touching the box requires you to “sit back” as you squat, as if you were lowering yourself into a chair, and this action gets the glutes and hamstrings maximally involved in the lift. It also helps you to perfect your squat form. You can start with a higher box and gradually move to smaller boxes as you improve, ultimately training your body to squat below parallel with no box at all. Better still, the box squat places no strain on the knees, so even people with knee problems can attempt it safely.
