> Sure it's easier to fast but you're missing out on the other benefits associated with exercise.

This is very true, exercise is very important for health regardless of its effect on weight.

> For cardio sure but for weight training you're burning calories and tearing muscle fibres to increase size/strength.

True, but you need to spend even more time to rack up 800 Cal worth of exercise by weight training compared to doing cardio, as a beginner or even an intermediate level gym goer.

It is also true though that weight training, if you actually successfully build muscle mass, can significantly increase your BMR and thus help with losing weight in that way, even if you're not spending hours or lifting hundreds of kilos at every session.

Yeah, unfortunately back of envelope physics math about the kC burned for lifting weights is deeply disappointing. Luckily our bodies are quite inefficient compared to a bomb-calorimeter, because back of envelope gets me less than a (k)calorie per 3 sets of 5 lifts, if you just do lazy potential energy math.

A tiny technical note - Cal is the official symbol for a "large calorie", equal to a kcal, 1000 cal, if you want to be precise but concise on the exact type of calorie you're talking about.

Duly noted!
