Hi mate have read through the thread- I don't think your eating enough protein or fat, fat supports a lot of important hormonal functions, makes you feel full and satisfied and most importantly tastes damn good!
when you are not engaged in endurance exercise ie longer than 10-12min and intense enough to make you pant then your body can generally maintain good energy levels with minimal carbohydrates. When your on the bike though your gonna need carbs cos you can't burn fat fast enough to support that level of energy output. I'm sure this is all known to you but when you eat carbs- smoothie 2 banana 2 green apple some dates etc- insulin is released into your bloodstream to shuttle the sugars into your cells, your muscles take what they need which isn't much then it starts geting stored as fat. Not only that though the process also encourages your cells to take up fluid which can make a person look a little puffy.
Now I'm not saying don't eat carbs as they a part of a well balanced diet but on days when your not in the saddle maybe hold back on the fruit and grain products, nuts, eggs, jerky all these things will keep you feeling full and without the insulin release from carbs (which also acts to facilitate fat transport and storage) your blood sugar will stay more stable= less hunger
"Eat meat, vegetables, some fruit, little starch and no sugar"
that is my 2c worth
