There’s mounting evidence that our body’s natural internal clocks, or circadian rhythms, drive a lot of our biological processes, including weight maintenance. They tend to sync up with daylight. That could be why studies have shown that shift workers tend to have a higher rate of obesity and weight gain—their body clocks are out of sync. One study even found that a third of people who experienced an interrupted sleep cycle for less than two weeks became prediabetic; all of the poor sleepers saw markers for the risk of obesity and type two diabetes climb.
Do this: Most guys who are fairly active and exercise regularly burn about 18 calories per pound of bodyweight or more per day. On that basis, a 200-pounder would consume 3,600 calories daily. To start dropping body fat, reduce your calories to between 14-16 per pound of bodyweight per day on workout days, or 2,800-3,200 calories daily. On nonworkout days, drop to about 12 calories per pound per day (2,400 calories for the guy who's 200lbs).
Whey protein is best known for its ability to increase muscle growth and recovery which becomes vitally important on any fat loss plan. Many of the benefits of whey are due to its fast digestion rate and high concentration of the amino acid leucine. It is important to remember that anything that is used to build muscle will also maintain muscle while dieting.
This question is on so many minds: how can I lose belly fat...and fast? While there's no magic formula of food and exercise to reduce belly fat with the snap of your fingers, there are nutrition choices, exercises and lifestyle changes that can help. Here's your guide to understanding exactly what belly fat is and how you might be able to reduce it over time.
Intermittent fasting—limiting your eating hours to just eight, say between 10:30 and 6:30—has gained popularity as a way to shake up your metabolism, and it just might work. “There is a lot more research that needs to be done but it does seem to benefit some people, particularly men,” says Angel Planells, RD, a spokesperson for the Academy of Nutrition and Dietetics based in Seattle. Another approach is to fast—or eat next to no calories (500-600 calories total)—two non-consecutive days a week. (You can eat normally the other five days.) The tactic seems to increase fat burning. “When your body isn’t getting fuel, it will start burning fat,” Planells says. Read about this woman’s experience with intermittent fasting.
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).
Do more HIIT: High intensity interval training (HIIT) is as close to a magic pill as we have (except it involves a whole lot more work than just swallowing a capsule—sorry). Not only does it surge your body to max intensity during the workout, but because you’re working so hard, your body can’t deliver enough oxygen in the moment, explains personal trainer Jeremey DuVall. Your muscles accumulate a “debt” of oxygen that then has to be repaid post-workout. This throws your body into a phase of fat burning for hours after you’re done sweating, known as post-exercise oxygen consumption, or EPOC. Plus, super intense circuits like this activate muscle-building hormones like growth hormone and IGF-1, he adds.
