I only drop by here on occasion. Yes, for alot of guys getting 5000 cals a day is very difficult. SInce you are 170, try to be selective in where you get those calories in order to minimuze body fat gains. In all honesty, while Muslce Milk can be a bit pricey, if you just can't seem to get in enough calories in the form of real food, it isn't that bad of a substitute. At least they add in some EFA's without fructose and a ton of synthetic sugars. My advice is to take at least 6 grams of fish oil a day. If you are on a tight budget, this is really a must have dietary suppliment if you are not eating some form of salt water fish several times a week.
Ensure Plus, athough not the most cost effective way to do it, should cover most of your vitamin and mineral needs that aren't being fulfilled by your high caloric intake. Give me a quick breakdown of your diet, if you don't mind, and I'll see what recomendations I can make. If you appear to be leaning out, but are gaining weight and people are telling you that you look bigger, you are heading in the right direction, even if you don't see it inthe mirror. Sometimes we are our own worst critics.
For those who don't understand where I'm coming from, I do ALOT of research on nutrition, as well as supplimentation, because I'm working on my BA in nutritional science. I plan on being a dietician after finishing college. I believe that the greater majority of suppliments are worthless, and many of the ones that are beneficial are way overpriced for what they contain. This isn't to say that people shouldn't make efforts to get certain fatty acids, vitamins, minerals etc, in the form of supplimentation if there is a benefit to doing so, but people should take the time to research, or at least get expert opinions outside of those who make their living selling these products. Flex magazine and the salesman at GNC are hardly good sourced of unbiased information.
ZK, you know my stance on saturated fat of course. I stand with the offical National Dietectics Association on this one. Its risks are over-rated, and it should be included and reasonable amounts in any heathy diet. The saturated fat needs of atheletes who desire to gain lbm are much higher than the average individual, since it has a huge impact on testosterone production in non-steroid using individuals.
