Having a larger waist circumference is a better indicator of health problems than commonly used measurements like body-mass index (BMI), according to a growing body of research. Specifically, having a waist size higher than 40 inches around for men or 34.5 inches for women is correlated with a higher risk for developing type 2 diabetes and heart attack. There's even evidence that having more belly fat is correlated with lower cognitive performance.
If you want to lose weight you should start by avoiding sugar and starch (like bread, pasta and potatoes). This is an old idea: For 150 years or more there have been a huge number of weight-loss diets based on eating fewer carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
A University of Vermont study found that online weight-loss buddies help you keep the weight off. The researchers followed volunteers for 18 months. Those assigned to an Internet-based weight maintenance program sustained their weight loss better than those who met face-to-face in a support group. These are 50 ways you can lose weight without a lick of exercise.
How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, 'The trick is not minding that it hurts.' I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
Swap giant dinner plates, bowls, and silverware for smaller versions, and pick up portion-sized packages of snacks instead of nomming straight from a full-size box or bag, says Cerderquist. You'll be eating less without even thinking about it. Another pro tip: stay away from protein bars. "It is amazing to see that an entire well-balanced meal can have the same amount of calories as many protein bars," she says. "But you are much more satisfied when having the variety of textures and flavors from a real meal."
This could be because the body increases insulin secretion in anticipation that sugar will appear in the blood. When this doesn’t happen, blood sugar drops and hunger increases. Whether this chain of events regularly takes place is somewhat unclear. Something odd happened when I tested Pepsi Max though, and there are well-designed studies showing increased insulin when using artificial sweeteners.
Lose fat with high-intensity interval training (HIIT). If you're trying to lose weight fast, HIIT training can super-charge your metabolism for upwards of 24 hours after exercising. This means your body will continue burning calories long after you've ended your workout. HIIT burns more calories in less time than steady-state cardio. In one study, researchers looked at two groups, one running for 30 to 60 minutes three times per week, the other doing four to six 30-second treadmill sprints, resting for four to six minutes between each sprint. After six weeks, it was found that the group doing HIIT training lost more weight.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
