Drinking strong coffee before exercising increases fat-burning, new study finds

Caffeine is performance-enhancing, raises metabolism (temporarily), and suppresses hunger.

Unfortunately, it's readily-apparent that you can never outrun your fork, so forget about "burning calories" through cardio. The goal of fitness to lose weight ought to be weightlifting to gain as much muscle mass as possible to raise one's BMR. Passive metabolism is about the only way to do it without enrolling in BUD/S. In general, gymrattery and endless treadmill running are wasted effort.

The additional fat loss due to increased lean muscle mass is minimal, comparatively. All of these things like “afterburn” effect (EPOC), etc are all to give people the illusion that there are easier ways to lose weight than eating less.

I’m not a keto maximalist, do whatever works for you. But most people looking to lose weight would do wonderfully on 1,250 calories per day of high protein, medium fat, with the odd day of fasting and plenty of water and coffee. Refeed every couple of weeks to keep leptin in check.

I agree.

From what I understand, a pound of muscle burns 6 Cals/day (that’s kCals, but in the US we just use Cals capitalized). A pound of fats burns 2-3 Cals/day. A 25 year old amateur non- drug- enhanced male can put on maybe 10 lbs of muscle in a year with a oot of hard work.

So the idea of putting on muscle to increase metabolism in order to get lean won’t pay off for most of us.
