you've made a points I'd like to go over.
Firstly and most importantly, making weight loss a struggle or a chore is counter productive. Well done on your current weight loss, but it would've been easier if you could've enjoyed it. That, and the fact that peer support is always a winner, means that group weight loss challenges remain statistically the best way of getting weight off (according to Trudy et al 2006)
No diet is unsustainable if you want it to work. Currently t2diabetes (obesity onset) is seen to be being reversed by a diet of 600kcals/ day for 8 weeks. (Christou & Efthimiou 2009- showed that a diet of 1200-1500/ day [post bariatric surgery] led to a average 50% excess weight loss in severely obese people over 10 months). The second example lost almost purely fat, at an accelerating rate until the 15th month when a plateau appeared)
Preoperative weight loss (req. before Bariatric surgery) is often brought about by very low energy diets (c 800kcal). In a study done on preoperative pts it was noted that despite this incredibly restrictive diet, weight loss was maintained at a uniform rate with an average loss of 15kg over 12 weeks (Colles et al 2006).
Glycogen is not a resource that sensible (ie dieters who don't drop carbohydrate) dieters deplete fast. Your total body store is 350g dry weight, or (as its roughly 3g water/ g glycogen) 1.2kgs total body weight. This is why the bonk occurs- glycogen represents a tiny amount of useable energy. Or why the theory is that after 30-45 mins of running you start to burn only adipose energy.
It is the body's second energy store after adipose tissue, which represents a whole shit tonne more kcal/ g as well. Effective dieting will aim to reduce your calories to a point where you can keep your glycogen stores, and keep hydrated (especially for dieters who wish to maintain/gain any muscle mass- as hydrated muscles are better), whilst losing fat. This is why diet shakes and protein shakes contain a significant sugar portion.
As a side note- as i read a couple of attached papers on my lecture notes- excercise is thought to be beneficial for maintenance of glycogen whilst dieting. (Garrow 1995)
Whilst, its true that the first few days can be water/ glycogen weight, it is very easy to maintain that.
In our Dietetics lectures, we're told that anything below 1200 kcals Resting input will cause unsustainable weight loss, and that the magic figure is %20 off daily calorie intake.
And it is true, of course, that a poor diet can lead to the massive sudden weight drop of water/glycogen loss- the idea of this thread is not to fall into that category.
Anyways, @ edmundro- your promax stuff can't be as bad as the stuff I'm on... I don't know what it is, it tastes like someone mixed flour with lucosade....
