How To Crank Up Your Metabolism Beat the downshift in metabolism that creeps up along with those laughter lines. With each passing decade, your metabolism slows down by about 5%. Ouch. Hormones are partly to blame, but so is the typical drop-off in physical activity. As a result you lose muscle mass, a major calorie consumer. So by the time you hit 35, you’ll burn about 75 fewer calories a day than you did at 25, and by age 65, it’s a hefty 500 fewer, says Dr Madelyn Fernstrom, author of The Real You Diet. But don’t panic. You can outsmart Mother Nature with the tips above. A warning: here’s what happens if you don’t. 20s: Your muscle and bone mass are at their peak and your metabolism should be firing on all cylinders. Enjoy it while you can. 30s: Your body’s cellular powerhouses, the mitochondria, start to get less effective at turning food into energy for your muscles to burn. 40s: The decline continues as your oestrogen levels go into free fall, further slowing your metabolism and causing belly fat. “You actually have a huge amount of control over your metabolic rate,” says John Berardi, author of The Metabolism Advantage. While peoples’ metabolism typically nose-dives with age (see below), studies show that you can limit that decline to as little as 0.3% per decade – without gruelling daily sweat sessions and extreme diets. FIRST THING Eat a decent breakfast. Every. Single. Day. If you don’t, your metabolism goes into starvation mode (it’s paranoid like that) and slows to a crawl. In fact, research published in the American Journal of Epidemiology found testers who ate no less than 22% and up to 55% of their total daily calories at breakfast gained only 1.7lb on average over four years. But those who ate less than 11% of their calories first thing gained nearly 3lb. See the pattern there? Crank it up: Go for morning munchies that are slow to digest. Try a mix of lean protein with complex carbohydrates and healthy fats. Berardi recommends an omelette made with one egg and two egg whites, plus a handful of sliced mixed peppers and onions. Follow that with a small bowl of porridge topped with a handful of frozen berries and 3 tbsp of omega-3-loaded flaxseed . Great, now you’re firing on all cylinders. AT THE OFFICE Rejoice, caffeine addicts. According to a study in the US journal Physiology & Behavior, the metabolic rate of people who regularly drank caffeinated coffee was an average of 16% higher than those who drank decaf. “Caffeine stimulates your central nervous system by increasing your heart rate and breathing,” says Robert Kenefick, a research physiologist at the US Army Research Institute of Environmental Medicine. We won’t argue with that, Sir. Crank it up: Follow your morning cup of the black stuff with an ice-cold glass of water. Researchers at the University of Utah found just drinking one glassful can raise your body’s metabolic rate by up to 30 per cent and keep it raised for around 10 minutes. The theory is your body has to burn extra calories to maintain its core temperature. Get your recommended eight glasses a day with the help of the free Waterlogged app, which gives you regular H2O prods. AT MEAL TIMES To slim down, pile your plate with protein. Regular large helpings will help you build and maintain lean muscle. And we all know muscle burns more than fat by now, right? Aim for 30g of protein – that’s 250g of low-fat cottage cheese or 100g of chicken breast – at each meal. Crank it up: Chase your meal with a cup of green tea. “It’s the closest thing to a metabolism potion,” says Tammy Lakatos Shames, co-author of Fire Up Your Metabolism. In tests, people who consumed three to five cups a day for 12 weeks shed an average of 4.6% of their total body weight. Another study found having two to five cups a day torched an extra 50 calories a day. Not bad. So go for Green To really go for the burn, down it two hours after eating. Research shows it can increase breakdown of fat by a third. Now go forth and burn.
