Suthin Sumthin

I TRY to donate blood on a regular basis.  I can spare it, it doesn't take long, I have several women fussing over me asking me how I am doing, telling me what a good fellow I am.  What's not to love?

I also have, I must humbly convey, really good veins.  One fellow said "massive pipes". The nurses like it because it's an easy poke.  I also fill up the little blood bag pretty quickly.

Last time I donated, rather on a lark, I drank a lot of water the night before, and during the night whenever I got up I took a wee sip.

That day (well morning) the nurse that attended me was SHOCKED at how quickly I bled out.  She had never seen anything like it.  I told her what I had done and she said that explained it and mentioned it to other staff.

It got me to thinking about the early days of my learning the field of fitness.  We sweat some all the time.  During the day we can compensate for it.  At night not so much.  We wake up in the morning dehydrated.  Just like there is breakfast there SHOULD be a break dehydration.

The moral of the story.  If you are a morning exercisers and you feel like you are not getting you best game on when you go to train.  Water. 

If you find yourself a little hard to settle in and get to business, water.  Dehydration, by lowering the fluidity of blood and thus limiting its travelability (yes I think I just made up a new word) affects both muscle and brain function. 

Now, go play !!!

Meal Frequency Review

The following is not mine. I am posting the abstract in total to make sure credit goes where credit is due.

Please note the mention that ghrelin, a hormone that is part of the signaling process for eating, was the same for both groups,  and that this was a small study.

One final point to ponder.  In our evolution was food always plentiful or did we have times of famine, and how does that relate to our chemical make today.

Increased meal frequency does not promote greater weight loss in subjects who were prescribed an 8-week equi-energetic energy-restricted diet.

Abstract

There have been reports of an inverse relationship between meal frequency (MF) and adiposity. It has been postulated that this may be explained by favourable effects of increased MF on appetite control and possibly on gut peptides as well. The main goal of the present study was to investigate whether using a high MF could lead to a greater weight loss than that obtained with a low MF under conditions of similar energy restriction. Subjects were randomised into two treatment arms (high MF = 3 meals+3 snacks/d or low MF = 3 meals/d) and subjected to the same dietary energy restriction of - 2931 kJ/d for 8 weeks. Sixteen obese adults (n 8 women and 8 men; age 34.6 (sd 9.5); BMI 37.1 (sd 4.5) kg/m2) completed the study. Overall, there was a 4.7 % decrease in body weight (P < 0.01); similarly, significant decreases were noted in fat mass ( - 3.1 (sd 2.9) kg; P < 0.01), lean body mass ( - 2.0 (sd 3.1) kg; P < 0.05) and BMI ( - 1.7 (sd 0.8) kg/m2; P < 0.01). However, there were NS differences between the low- and high-MF groups for adiposity indices, appetite measurements or gut peptides (peptide YY and ghrelin) either before or after the intervention. We conclude that increasing MF does not promote greater body weight loss under the conditions described in the present study.
