If you're eating less calories than you should be, you'll be doing more harm than good.
Hi milkyway, I know you didn't post the original but thought you may know the answer anyway. Actually I am confused and was wondering if some of those figures above have been reversed maybe OR wrong? (especially the fat intake) OR if I am missing something?
For example I'm a guy, have just over 20 Kgs to lose now but if I use the guide above its telling me to consume 2,000 calories (inclusive of 56g of fat). My first question would be does this include exercise but my second question would be, (having read elsewhere that for me to sustain my current weight I need to consume approx 2,600 calories and no more than 60g of fat) yes I can see that I am benefitting by consuming 600 calories less a day but am concerned this is not really enough (especially with the fat content being only 4g better off) to give me any meaningful weight loss, especially from a fat intake point of view. ie - we know that to lose 1 pound a week we need to consume 3,500 calories so that reduction on the face of it looks acceptable being 4,200 calories and slightly over a pound a week but am still concerned my body fat won't be reduced by much because of only a 4g reduction per day meaning my body fat loss will be under 30g a week (negligible compared to the 20,000g l need to lose.)
Conversely (using the above figures) if I only had 5 Kg to lose I am being told I can cut my calorie intake by an additional 500 calories a day but more importantly cut my fat intake by an extra 14g a day. ie using these figure I'd lose an extra pound a week on the calorie scale (over two pounds in total) and be sure I'm losing body fat because the total saving would be 18g a day and 126g a week (not neglible in comparison to the 5,000g that needs to be lost?)
Can you see my confusion and concern here? What its telling me is a number of things which I don't know are particularly true (maybe someone can tell me.) Firstly that someone with less to lose can lose his weight a lot quicker and I'm not talking about total weight here, am talking about say Kilo for Kilo. Secondly its telling me that a heavier person is being told to eat more fat per day which just doesn't seem right in the whole scheme of things.
Now I also know that a heavier person needs more calories to fuel their bodies at this heavier weight but surely thats the point of wanting to reduce intake? and especially fat intake. I can sort of see why a lighter person would be able to input less calories but for the life of me the introduction of these fat weights have me concerned.
In essence I am concerned about the fat intake in general above as have been led to believe women take 41 grams and men 60 grams which the body can readily burn and the figures above (especially for women) are exceeded meaning perhaps that any weight loss at all may not be body fat.
Hope I have made sense there in my questions and again appreciate it wasn't you that wrote the original.
