Hi guys,
I've spent a ton of time over the past ten years researching nutrition and fitness. Not as a job or in college or anything, just out of personal interest. Thought I'd give my two cents.
I (mostly) eat a diet high in fat and protein, and low in carbs (carbohydrate - sugar and starch). I "feel" that this is the best way to eat and many many people, from dieticians to personal trainers to athletes feel the same way.
A high fat and protein diet doesn't need to be unhealthy. I can already see some of you frowning or laughing at this post or thinking "what a noob", but if you are careful about food selection and diligent in preparing your food, you could end up really healthy and stay that way for a long time.
I'll just offer a few guidelines and give an example diet (the meals I ate today, actually).
Basically, if you cut out 80% of the sources of sugar and starch in your diet, you will end up cutting out almost every food that is bad for you.
This means no bread - which is practically poison to most people, pasta, potatoes, rice, pastry, pizza, sweets and deserts, breakfast cereal (dust with milk), soft drinks/sodas, fries. All that good stuff needs to go.
Heres why (in laymens terms). When we eat a carb (sugar or starch), it causes a spike in blood insulin. Even "complex" or "slow release" carbs do this. The insulin causes our body to shuttle protein to the muscles (which is good after a hard workout), and add adipose to body fat stores while PREVENTING our body from burning excess fat.
These insulin spikes inevitably cause a "downswing", leaving you tired and unfocused after an hour or so.
You will notice that those heavyset people you know tend to eat A LOT of starch, even if they never eat sugar.
There is one exception to the no carb rule, which is after a hard workout. Then I eat my only carb laden meal of the day. I don't go crazy with sweets and bagels. Instead, I have a chicken curry or beef chilli with brown rice, or fish with homemade sweet potato chips (baked, not fried). Sometimes I have pasta, though I tend to avoid wheat.
So from where do we get our energy? Quite simply, we get it from fat, and saturated fat is King. Don't worry about cholesterol dangers or heart problems. These issues are almost never caused by dietary fat when it is taken from a natural source! These natural sources are red meat like steak, mince, pork, lamb, eggs, seafood. Mcdonalds burgers or sausage and bacon do not make the cut.
Whenever you think of eating something, ask yourself this:
CAN I PICK THIS AND EAT, OR KILL THIS AND EAT IT?
Basically, is the food natural, or has it been processed beyond recognition?
Pick natural food, lots of meat and veg, no sugar or starch, lots of water (shoot for 2 liters a day, more on training days or if you live in a warm country).
Take a good multivitamin+mineral (mineral is more important for most of us) and fish oil supplement.
Protein powder is useful, but not essential.
Here is what I have eaten today:
Breakfast Smoothie (one hour before gym)
Carrot, banana, handfull berries, scoop peanut butter, scoop whey protein, some milk
Spoon fish oil and multivitamin/mineral tablet (taken seperate, not added to smootie)
Always try to add one veggie to a smoothie. I promise you wont taste it!!!
Lunch (after my weights session)
Curried mince beef (Indian shtyle) with chick peas and peppers and brown rice
Dinner
4 Scrambled eggs with a small amount of bacon (like one slice, maybe two), some peppers and onion.
Evening meal
2 pork chops, shallow fried or grilled with a side salad (lots of lettuce, olives, seeds, etc, whatever you like really) and a little dressing. Olive oil and balsamic vinegar works well here.
Before bed
Whey protein shake with milk (I use a coconut milk replacement coz dairy gives me the sh!ts), teaspoon fish oil and miltivitamin tablet.
I snack on nuts (unsalted) and fruit if I get the munchies, or I dip carrot or celery into houmous.
You can see that the diet is pretty healthy, all natural food, no processed junk. It is also simple, with each meal taking 15-20mins to prepare and only a further 5-10 mins to cook (and with meal one, the carb meal, you can prepare a few days worth in one go)
I follow a similar diet most of the time, only eating "junk" when I'm out for a meal with someone (I dont want to be "that guy"), or on a weekend away or drinking session with buddies, but these things are rare events for me now.
Please realize that other than my workout (I train 5 days a week, 30-60 mins per session), I am very inactive. People playing sports (really playing, not just kicking a ball around with friends), or working in manual labour like construction, will need more food, and may need to add more starch for convenience. Most of us, meaning 80-90%, DO NOT NEED STARCH OR SUGAR IN OUR DIETS.
If you are wondering, my blood profile (cholesterol, triglycerides etc) is perfect. My blood pressure is slightly elevated because a smoked for years and drink often (hey, Im Irish!!!!)
If anybody would like links or info on weight training, fitness training, diet help etc please let me know.
