Your primary goal should be to get active and stay motivated to keep moving.
Scott Douglas writing for the Washington Post:
If you’re the kind of exerciser who constantly checks your heart rate to ensure you’re in the fat-burning zone, you should stop. You’ll probably never meet your weight-loss goals that way. That’s because there’s no special fat-burning zone that’s key to getting lean.
Your body primarily fuels itself by burning a mix of stored fat and carbohydrates. The less active you are at a given moment, the greater the percentage of that fuel mix comes from fat. As your intensity of activity increases, the percentage of carbohydrates in that fuel mix also increases. At rest, fat constitutes as much as 85 percent of calories burned. That figure shifts to about 70 percent at an easy walking pace. If you transition to a moderate-effort run, the mix becomes about 50 percent fat and 50 percent carbohydrates, and it moves increasingly toward carbohydrates the faster you go.
Increasingly researchers are finding that your intestines not only digest food, but may also regulate mood, emotion, and play a central role in your body’s response to disease.
What you eat feeds every single cell in your body.

Avoid processed deli meats and red meat while feeding the dense jungle of bacteria in the colon with fibers, fruits, and vegetables. Siegel says unhealthy and sedentary lifestyles rife with fast foods and processed meats are contributing to the rise in colon cancer among young people. A lot of people go to the deli and buy very expensive turkey breast and think they are eating healthy, Siegel says. Shifting away from the standard Western diet to the Mediterranean diet — composed primarily of plant-based foods, olive oil, fish, and mixed nuts — supports both gut health and a healthy heart. Sprinkling food with curcumin — the activated ingredient in turmeric — may dampen inflammation. Routine exercise staves off obesity, which does wonders for the gastrointestinal tract and reduces cancer risk. While particular diets are effective in treating specific gut conditions, consult with a gastroenterologist or nutritionist before pursuing anything radical.
“Runners should be instructed to choose a certain type of running shoe over another shoe no more so than a blue shoe over a red shoe,” writes Chris Napier in the British Journal of Sports Medicine.
From The Globe and Mail:
A decade ago, an Australian sports-medicine physician named Craig Richards launched a ferocious broadside at the running-shoe industry. Writing in the British Journal of Sports Medicine, he and two colleagues argued that there was no evidence whatsoever that modern running shoes prevented injuries – and that, as a result, such shoes should be considered “unproven technology with the potential to cause harm.”
That critique went mostly unnoticed at first. But a year later, in 2009, the bestselling book Born to Run ignited a surge of interest in barefoot and “minimalist” running, and a corresponding wave of scorn for conventional running shoes. Richards and his colleagues suddenly looked prescient – the progenitors of a new, evidence-based approach to footwear.
As the years have passed, though, demonstrating the superiority of other types of running shoes has proven to be more difficult than expected. As a new editorial in the same journal now argues, we’re still waiting for evidence about the injury-preventing powers of running shoes – except that the critique now extends to newer approaches such as minimalist shoes, supercushioned maximalist shoes and even the suggestion that you should simply choose a shoe based on comfort.
The editorial, from physical therapists Chris Napier of the University of British Columbia and Richard Willy of the University of Montana, identifies a series of logical fallacies that permeate current debates about running shoes.
The best running shoe, it could be argued, is the one that is most comfortable for you, will get you out the door, and is on sale.
