Yes, but consider this: A 1235-pound man has slimmed to 700 pounds without exercise.
Many of us eat 1000 daily calories more than we need, yet an hour of exercise burns far fewer than 500 calories (typically less than 200 calories per hour) and may actually increase calorie intake. Quenching post-exercise thirst with a bottle of Snapple adds 250 calories. These numbers alone cast doubt that we can exercise our way to weight loss. Exercise is important for health, but a sustainable reduction in calorie intake is the key to long-term weight loss.
Too often a physical impediment to vigorous exercise is offered as an explanation for inability to lose weight. And though exercise does offer benefits, unrealistic prescriptions for a daily hour dedicated to exercise provide another excuse for obesity. Fifty years ago, without complaining of hunger and without paying for fitness centers or home exercise equipment, most people stayed trim eating fewer calories and engaging in routine daily activity.
Try parking farther from your destination so you walk a block (or more) each way. Wash your car with your kids instead of at the car wash. Mow your lawn. Take a flight of stairs instead of the elevator. Walk for a half hour with your family after dinner each day. Get up and change the channel by hand.

This excerpt is from an editorial by a group of doctors, including British cardiologist Dr Aseem Malhotra–an outspoken critic of the food industry, published in the British Medical Journal, 22 April 2015:
In the past 30 years, as obesity has rocketed, there has been little change in physical activity levels in the Western population. This places the blame for our expanding waist lines directly on the type and amount of calories consumed. However, the obesity epidemic represents only the tip of a much larger iceberg of the adverse health consequences of poor diet. According to the Lancet global burden of disease reports, poor diet now generates more disease than physical inactivity, alcohol and smoking combined. Up to 40% of those with a normal body mass index will harbour metabolic abnormalities typically associated with obesity, which include hypertension, dyslipidaemia, non-alcoholic fatty liver disease and cardiovascular disease. However, this is little appreciated by scientists, doctors, media writers and policymakers, despite the extensive scientific literature on the vulnerability of all ages and all sizes to lifestyle-related diseases.
Instead, members of the public are drowned by an unhelpful message about maintaining a ‘healthy weight’ through calorie counting, and many still wrongly believe that obesity is entirely due to lack of exercise. This false perception is rooted in the Food Industry’s Public Relations machinery, which uses tactics chillingly similar to those of big tobacco. The tobacco industry successfully stalled government intervention for 50 years starting from when the first links between smoking and lung cancer were published. This sabotage was achieved using a ‘corporate playbook’ of denial, doubt, confusing the public and even buying the loyalty of bent scientists, at the cost of millions of lives.
