Assuming that by "4:2" you are talking about intermittent fasting, does anyone believe otherwise? Alternate-day fasting can help people lose weight not because there's any magical effect, but because a faster is unlikely to double their calorie intake the day after fasting - having fast days is just a simple/easy way to reduce overall calorie intake. Besides, the main benefits of alternate-day fasting are meant to be health related, not explicitly weight-loss. Is it a main-stream weight-loss method?

Intermittent fasting combined with weightlifting means you are more likely to loose fat and not muscles while fasting. The weightlifting will tell the body that the muscles are needed and it will then have less of a tendency to metabolize them for energy. Also muscles burn energy while you are sitting on your sofa. Increasing your muscles mass by weightlifting means you will burn more energy all the time. I think weightlifting is strongly overlooked for weight loss and especially for loosing fat when combined with intermittent fasting.

  Do you have a source for that? First, I'm talking about actual weight loss, not fat loss. They are two different goals. Weightlifting causes muscle damage that needs repairing. This requires energy. Intermittent fasting will cause longer repair times and if done incorrectly will cause muscle loss. (muscle bulk I assume is your end goal, as opposed to a specific need for a sport) However the common way to gain muscles is to take protein powder laced with hormones, natural or otherwise. As a strategy for weight loss it is useless unless you exercise enough to burn off the extra calories consumed. This requires time and effort, both of which are difficult. Loosing fat is not in its self weight loss.

It is marketed as a diet. however its based on the idea that if you have a reduced calorie intake you'll live longer. However: a) its yet to be proved in humans (worms, flies and lemurs, yes.)[1] b) to get the benefit we're talking about ~1800 calories a day. Having accidental done something like that for almost a year, I cannot stress how terrible your quality of life is.

  I don't believe we have the structures in place ever to 'prove' alternate-day fasting will extend human life. In response to your point b), presumably you mean the deficit is ~1800 kcals per fast day? Why was this so terrible?
