There really isn't that much science to it. On paper its really really simple.
To loose weight, you must expend more energy than you absorb.
However, conversely to get fit, you will need to eat a balanced diet, with enough calories to replace damaged muscles.
However on the weight loss front here are the golden rules:
Some people exercise (exercise expends energy)
Some people reduce energy consumption (eat less, or eat less calorific food)
Some people combine both.
There are no other options.
Seriously, if you are on a diet and you are not loosing weight, its not because you are unlucky, its because you are still absorbing more energy than you are expending. Exercise more, or eat less.
There is some evidence that efficiency can be altered by eating patterns, however that's not enough to over come eating an extra 300calories a day.
Everything else, is literally junk science. The 4:2 only works if on arrogate you consume less calories. Atkins only works if you can't absorb the extra energy you have in fat and protein. Etc, etc, etc.
This part is the easy part. Weight in 90% of cases is a symptom of one's environment. Changing environment is devilishly difficult.
- NLips 11y agoAssuming 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?
- Sammi 11y agoIntermittent 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.
- KaiserPro 11y agoDo 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.
- KaiserPro 11y agoIt 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.

- NLips 11y agoI 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?

There is at least one other way besides exercise to expend energy: cold exposure. http://www.theatlantic.com/magazine/archive/2015/01/does-global-warming-make-me-look-fat/383509/ http://www.theatlantic.com/magazine/archive/2015/01/does-glo...
