re: Low Fat Diet Is Allegedly Wrong According to Report

laws of thermodynamics

Why don't you explain the thermodynamics of digestion and metabolism? You sure like to use the word "thermodynamics" when talking about nutrition, but I have never seen you explain it (I may have missed it).

Further, can you explain how the calorie, which is the amount of energy required to raise one gram of water one degree celsius (food calories are kcal), fits into energy production, storage, and expenditure of the human body?

K, thx, l8r

I've lost weight by eating more fats and staying away from carbs/sugars.

Obviously crash diets don't work, binge eating doesn't work, and eating too much doesn't work.

About four months ago, my entire family switched to a high-fat, low carb, gluten free/wheat free diet.

I was already pretty healthy to begin with, but now I'm build like a damn Greek Gawd. I've leaned up but weigh the same.

I eat bacon all damn day, lots of nuts, and tons of meats like chicken and also a lot of fish. I still incorporate beef, but the gist of the diet is to trim out all the wheat products and by products.

Both of my kids look healthier, their moods are completely different, and they aren't always running like they are on a sugar rush.

My wife lost about 10 pounds in the first three weeks and is leaning up nicely as well.

The immediate results were astounding as well.

I can't say enough about the new approach.

Reminds me of the hulkklogan fitness advice days where the kid weighed more than 275lbs for two years straight despite doing a "low carb" diet.

I'm still around. However, I'm a little more hesitant to give advice, particularly the militant "LOW CARB IS THE ONLY WAY" view I had before. Instead, I recognize that my weight journey (re: loss, gain, and re-loss) is mine and mine alone; my experiences are mine. Everyone is different and can reach their goals different ways.

I cannot reasonably blame my weight loss failures solely on low carb dieting. In fact, quite the opposite. Anytime I try losing weight without giving up carbs, I struggle to lose weight. Whatever the issue may be, be it overeating carbs, or caving into cravings, I just have a much easier time losing weight when I cut out the carbs. Again, that's just my own experience talking.

My largest failure in this journey so far has been after hitting my initial goal of 113 pounds lost (reached 250 pounds at 6'2), I caved in and fell off the wagon for nearly 2 years. In those 2 years I put a little over 50 pounds back on. Much of that "falling off the wagon" I actually was still exercising, lifting weights 5-6x a week, but much of the diet fell off of a cliff. The weight gain was slow at that point, and I was actually putting on muscle. However, at some point I stopped exercising as well. Became the lazy fatass that ate everything in sight as I was before. I saw myself put on ~30 pounds in ~7 months and realized I was on the verge of spiraling out of control.

Here I am today, losing weight again, fighting the good fight. There's a good chance I'll fail again, but I will not give up.

So, no, you can not explain it in reference to metabolism and digestion.

---

No i fricking can but it is useless in the terms of this discussion.

quote:

---

A calorie is a terrible measure of energy in a biological setting. The amount of "energy" in a food source does not equate to the amount of energy that the body will utilize from that source. The body digests foods differently (and each person's body will digest food differently based on your previous eating habits and exercise level, but that is too complex for this discussion).

---

Well you don't fricking say? wow what a shock. Think maybe thats why i mentioned finding ones TDEE? You won't be able to know it exactly right off the bat but you can get close enough using online formulas that you can adjust things until you find your maintenance.

quote:

---

For instance, insoluble fiber "has" calories but your body will not use any of those calories. Thus, "calories in" has 0 effect on energy use by the body. Similarly, equal "calories" of simple carbs and complex carbs will have different energy effects: simple carbs will use almost no energy to become usable energy while complex carbs require digestion (which uses energy) to become usable energy.

---

Again no shite, i touched on this when i said some types of calories take more energy to digest.

quote:

---

Also, the effects of what you eat will change the physiology of our bodies. Some foods at 100 calories will trigger your body to produce fat while an equivalent amount of calories of a different food source can instruct your body to burn fat.

---

and this is wrong. no food triggers fat storage period. its why people can lose massive amounts of weight eating twinkies and other junk. Your premise is wrong in the grand scheme of things. Now certain foods tend to trend more toward the muscle building side of things(protein) but even too much of that can and will cause fat gain. there is no magic food that causes one to gain weight or lose weight.

quote:

---

These are just simple examples which convey the point that calories are not equal and the "laws of metabolic thermodynamics" are a lot more complex than the first law of thermodynamics.

---

only if you are breaking it down into the efficiency of certain foods. in the grand scheme of calories in vs calories out the first law is all that applies.


let me guess though, you are a know it all nutritionist that sits at about 20-25% body fat that pretends to know it all when it comes to losing weight.

You automatically lose 10 lbs of water weight when switching to low carb. You'll look leaner but only because you are water-depleted. This is why you'll "gain it back so quickly" when you indulge in moderate-to-high carbs. Just keep this in mind.

I think anyone posting nutritional advice should be required to post a picture.

while i agree, I don't want to post mine for 6 more weeks damn it, and I sure as frick ain't posting it on the OT.

Quit looking for a magic shortcut. It doesn't exist.

Shortcut/magic?

The rationale I have summarized is neither. It is a more nuanced explanation of the how and why high quality, nutrient dense foods matter (and I didn't even get into the effect on the micro biome..). You take exception to that?

PS: You still have not answered the initial question posed (which was the point of my previous analogy).

Read this. Comment if you think you would be OK feeding your kids/family a twinkie diet (which by your logic should suffice as it is strictly about calories isn't it?).

Image below: Vit A,D,E, K are all FAT soluble vitamins...

Here is the deal. You will not see immediate harm. You may be fine for a few years, It may take DECADES before insidious changes take hold and MANIFEST. This is current state of the American populace from DECADES of poor dietary recommendations with the calories in, calories out model contributing (along with the low fat recommendations). Last image capture this well (although I hate BMI as a metric in general)

Low micronutrient intake may accelerate the degenerative diseases of aging through allocation of scarce micronutrients by triage

Bruce N. Ames* Nutrition and Metabolism Center, Children’s Hospital of Oakland Research Institute, 5700 Martin Luther King Jr. Way, Oakland, CA 94609 Contributed by Bruce N. Ames, October 6, 2006 (sent for review September 20, 2006)

Inadequate dietary intakes of vitamins and minerals are widespread, most likely due to excessive consumption of energy-rich, micro- nutrient-poor, refined food. Inadequate intakes may result in chronic metabolic disruption, including mitochondrial decay. Deficien- cies in many micronutrients cause DNA damage, such as chromosome breaks, in cultured human cells or in vivo. Some of these defi- ciencies also cause mitochondrial decay with oxidant leakage and cellular aging and are associated with late onset diseases such as cancer. I propose DNA damage and late onset disease are consequences of a triage allocation response to micronutrient scarcity. Epi- sodic shortages of micronutrients were common during evolution. Natural selection favors short-term survival at the expense of long-term health. I hypothesize that short-term survival was achieved by allocating scarce micronutrients by triage, in part through an adjustment of the binding affinity of proteins for required micronutrients. If this hypothesis is correct, micronutrient deficiencies that trigger the triage response would accelerate cancer, aging, and neural decay but would leave critical metabolic functions, such as ATP production, intact. Evidence that micronutrient malnutrition increases late onset diseases, such as cancer, is discussed. A mul- tivitamin-mineral supplement is one low-cost way to ensure intake of the Recommended Dietary Allowance of micronutrients throughout life

He's on the 3 rep workout plan.

Seriously. I think it was called body by science

It is body by science, but not 3 reps. And for some anecdotal evidence, I used to do weights twice per week and cardio 3 to 4 times per week and I am stronger and leaner now with working out only once or twice per week for about 15 minutes each session.
