Good advice, though I think he overemphasizes the gym. The point of exercise is to emphasize how much overeating costs you. It's harder to justify that candy bar when it equates to an hour of hard exercise.
Very true. I burn 1000 kcals in an hour of running on an easy day, and closer to 1300 during a tempo workout.
Also, the health benefits of cardio are numerous, ranging from stress reduction to neurogenesis to longer telomeres. It's not just about how good looking your body is.
700 kcals is on the extreme high end for an hour of cycling. You'd have to be fairly heavy already and pushing it as hard as you can go. A normal person putting in average effect is probably more like 250-300 kcal.
I weigh 145. 700 kcals is about "tempo" effort: hard, but still fun-hard. All out, in the best shape of my life for one hour is around 900 kcals. I'm in good, but not phenomenal shape; my brief flirtations with road racing ended in utter humiliation.
I know this because of my on-bike power meter, which measures mechanical work in kJ. That "perfect hour" was around 280 W, and I've done it twice. (Cyclists have a very narrow range of biological efficiencies, so you can just multiply mechanical by a constant to reckon metabolic work.)
He uses the guilt of owning a gym membership to make himself more disciplined. I think if he did better on being disciplined and super-disciplined, the gym membership wouldn't be necessary.

An hour of hard cycling burns about 700 kcals, which is a medium-sized meal. A candy bar is on the order of 250 kcals typically.

The point of exercise is so that when you do lose weight you don't still look like crap.
Losing weight is all about diet.
Looking good is about diet and exercise.
