Is A High-Protein Diet Bad For Your Kidneys?

is a high protein diet bad for your kidneys?So, is a high-protein diet bad for your kidneys?
In a word ‘no’.
More specifically, protein may only bad for your kidneys if you have bad kidneys ;) .

If you use the formula I use to calculate how much protein you need to build muscle, you’ll probably be consuming about 20-25% of your daily calories from protein. Hardly enough to place undue stress on the kidneys.

To illustrate the point here’s a study that tested the hypothesis that a high-protein consumption would adversely affect the kidneys.

One group is put on a high-protein diet, the other on a low-protein vegetarian diet. The conclusion - speaking of the higher-protein diet it says:

“such a diet does not significantly affect kidney function with “normal aging” in healthy subjects.”

Enjoy your salmon everyone :)

Is The Atkins Diet Safe? Answer May Shock You!

is the atkins diet safeI could have named this article, “25 year vegetarian admits Atkins diet is the best!” and it would have been accurate!

Most people don’t question the awesome effectiveness of low-carb dieting for weight loss. However, the number 1 issue is always, ‘Is it safe?’.

I’ve already blogged about the saturated fat & cholesterol myths but more and more results of studies just keep coming in.

I want to bring to your attention a study conducted by the Journal of the American Medical Association and presented here at Stanford University (Lecture filmed on January 17, 2008).

The lecture below is given by a 25 year vegetarian, Christopher Gardner, probably not the best candidate for telling the world about how healthy a low-carb diet is. However, he is fair and balanced in his approach and seems like his intention is to actually help people succeed rather than push his own preconceptions down people’s throats - how refreshing!

The low-carb diet of choice for this study was Atkins, so if you’re wondering ‘Is the Atkins diet safe?‘, you’ll want to watch this one with interest.

The results aren’t surprising to me in the slightest, but I hope a few of you skeptics start to reconsider what constitutes a healthy diet.

The study involved 311 women over a 1 year period. They were split into 4 groups, each group doing their own diet. At one extreme, we have a very low-fat/high-carb diet. At the other, a very low-carb/high-fat (Atkins) diet with the other 2 diets falling somewhere in between.

Well, guess what diet produced most weight loss? Atkins of course - by now that shouldn’t surprise you.

However, they were also interested in how healthy each diet was. Here’s the point (and something I’ve been stressing for a long time), Atkins beat all other diets in every single health marker - ALL OF THEM.

The Atkins diet saw most improvements in:

  1. Weight
  2. Systolic Blood Pressure
  3. Diastolic Blood Pressure
  4. Triglycerides
  5. HDL cholesterol
  6. LDL cholesterol
  7. Insulin
  8. Glucose

To quote Gardner “There was no group that did better than Atkins in anything“.

This is a long video so I’ve made a note of the most important parts for you.

  1. Watch 20min to 26 mins - Results of the Study
  2. Watch 53.30 to 54.30 - Here Gardner says how hard it was to admit that Atkins works best. He says it in good spirits though, I respect that :) . He shows his openness to low-carb by saying, “I think there’s something there.” Wow, someone actually respecting what the data really shows!

Enjoy the show!

How To Build Muscle Mass Fast - Complete Guide

how to build muscleIn learning how to build muscle, people are often lead astray by unsubstantiated claims, fad workouts and diets.

You will note that the title of this article is ‘How To Build Muscle Mass Fast‘ - this is not to say you can ‘build crazy muscles in a week’ or other such nonsense. What you can do though, is maximize your potential for muscle growth naturally. This commonsense guide therefore represents the fastest way to build muscle.

In this article, I’ll summarize all the fundamental points of muscle building. It’s a good refresher for those already on the journey, and a great place to start for beginner bodybuilders (at the bottom of the article there is a definition of terms for any beginners among you).

How To Build Muscle 101

(1) Lift Weights - no doubt about it. Weight-training beats everything else for building muscle. Body-weight exercises (calisthenics), gymnastics, cardiovascular work, all may build some muscle for total beginners but only a little - then it stops. Why? Because you can’t add ever-increasing resistance with these other forms of exercise.

(2) Force Your Body To Adapt! Continuing from point one, your muscles will have no reason to grow if you don’t place them under ever-increasing demand. What this means is that the weight you can lift on any given
exercise should increase over time. No increase = no growth. This is the concept of Progressive Overload.

(3) Train For Hypertrophy & Avoid Strength Training. Hypertrophy means muscle growth. You want to specifically target this, as opposed to strength-training which has its focus primarily on strength gains with building muscle as a happy side-effect. Training for strength usually means a low rep range and compound-only workouts. While compound exercises are vital to a good workout, no-one is building bulging biceps with military presses and squats. Read on…

(4) Do Compound + Isolation Workouts - Compound exercises are crucial, they involve many muscle groups simultaneously and induce the release of growth hormone in the body. However, what if I want to shape my biceps? Work on the outer portion of my shoulders a bit more? This is where ‘compound-only strength training’ and Olympic weight-lifting is found wanting. I simply cannot train my biceps with enough intensity to produce continual growth without isolating that particular muscle.

(5) Train with A Full Range of Motion. Building muscle mass is all about feeling the muscle throughout the whole rep i.e. the concentric and eccentric part of the rep. To really mess this up, use weights that are too heavy for you, use too much momentum throughout the rep and do super-quick reps. This is another flaw of using ‘Olympic Weight-Lifting’ type exercises as your means of building muscle. Those type of exercises use a lot of momentum & fast, snap movements such as in the ‘Jerk’. This movement is not a muscle builder.

(6) Eat - Get enough calories. No matter what bodybuilding diet you are on, you need to eat enough to supply your body with what it needs to grow. Go here to see how many calories you need to build muscle.

(7) Get Enough Protein - No you don’t need astronomical amounts of protein to build muscle, but you do need more than the average guy. Use the following calculation:

Lean Mass Weight (Kg) x 2.75 = Daily Protein Requirement

(8) Train In The 8 - 12 rep range. I call this the hypertrophic rep range. Basically, you should reach failure on each set on the 8th, 9th, 10th, 11th or 12th rep. When you can hit 12 or more, increase the weight used for that set.

(9) Keep Your Workouts Short. Steroid users can train for hours, natural bodybuilders can’t. Catabolic hormones are released in the body which actually break muscle down. To minimize this, try to keep all weight-training sessions to a maximum of 45 minutes.

(10) Take a Rest Between Workouts. If your priority is building muscle, what good could cardio do? I understand that you want to stay lean while you build muscle but this is best accomplished with a carb-cycling bodybuilding diet. Leave cardio until you want to prioritize fat-loss.

(11) Allow Adequate Rest Between Sets. Building muscle is all about performing at your best each and every set. Research shows that rest periods between sets of less than 1 minute reduce the amount of power muscle can produce in successive sets. Resting more than 3 minutes provides no further benefit than resting for 2 minutes. Therefore to strike the optimal balance between time-saving and maximum results, rest for around 2 minutes between sets.

(12) Drink Water. To build muscle at the maximum rate you need to drink enough water. Use this general rule:

Body weight (lbs) X 0.6 = Water Intake in ounces.

Remember strength can decrease by up to 15% with a drop in hydration levels of only 3%!

Definition of Bodybuilding Terms

  • Reps - A single cycle of lifting and lowering a weight
  • Sets - A number of consecutive reps without rest
  • Hypertrophy - Muscle Growth
  • Compound - An exercise that moves the body through more than one joint movement
  • Isolation - An exercise that moves the body through a single-joint movement
  • Concentric - The part of the rep where the muscle contracts and shortens
  • Eccentric - The part of the rep where the muscle lengthens
  • Failure - The point at which you cannot possibly perform another rep

So, with all this said, can YOU do it? Can you build the body you want? Of course you can. I was a weed with a fat belly once too. If I can do it, anyone can!

Stay Motivated!
