I'll concur with this. I have been practicing one meal/day for almost 3 years now. I think it took my body over a year to really adjust to all the benefits. Now I realize I have some big eating days, some small eating days, I mostly crave healthy stuff and I let the rest take care of itself.

What about feeling tired/lethargic during the time in which you fast? Also, can your body really efficiently utilize all of the micro/macro nutrients it needs in a day when it's handed them all at once? I agree that IF can be a good little mental trick for a quick cut, but I'm skeptical on one meal a day for a life time and if there's any negative effects that could come up.

Anecdotally, I usually feel dramatically better when I fast. There is an incredible mental clarity and productivity that itself makes fasting worth it. I don't feel tired when I fast - in fact, I often feel like I could easily go for a 10-mile run.

FWIW, it takes getting used to. If you drop everything and do a 24-hour fast after years of "6 meals a day", you will feel cold, irritable, and unproductive.

Also, coffee is a powerful thing.

> The answer is "Don't eat foods that raise your blood sugar above 140mg/dL". Is that related to glycemic index?

Sort of. The glycemic index is not really useful because it is based on arbitrary quantities of food. Glycemic load was created to be useful to people, as it is based on reasonable quantities people would eat. Like GI says watermelon is bad because its calories come from sugar. But it is based on eating 100g of carbs from watermelon. That's a huge amount of watermelon, which is mostly water. GL shows watermelon is fi…

Thanks. I never realized that glycemic index and load were different things.

I seem similar. I've lost 92 lbs over 8 months, and I don't seem to be having problems. In particular, I'm not having any feelings of hunger. I've pretty consistently been averaging a tad under 2000 calories/day, 35% carbs, 21% proteins, 44% fats. One interesting thing is that if I go significantly over 2000 calories in a day, which happens maybe once every couple of weeks, I find myself automatically eating less the…

As someone who (over the last 6 years has) lost 65 lbs (245>180), regained 45 (225), lost 40 (185), and am now up 25 and back at 210 I can tell you that this will creep up on you if you don't remain diligent about sticking to your new eating habits. Sugar addiction has continually crept back in my life despite sticking to low carb diets for almost a year on more than one occasion.

I second this. Sadly I am up about 35 pounds from when I hit bottom.

Sugar-addiction, at least for me, is harder to beat then smoking. I am able to go without sugar for one to two weeks and then it hits me and I binge on chocolate again.

Hope to find the strength to restart my efforts.

Does any of you have helpful suggestions?

Exercise has nothing to do with weight loss. Caloric restriction also doesn't work without consuming the correct fats to satiate your appetite. As you age there is no amount of exercise that will allow you to maintain the amount you weigh in you 20's or 30's. It will all depend on your diet of the correct foods. I would suggest probably the best book ever written about why people get fat. Why We Get Fat: And What to…

For another perspective on this, see: http://anthonycolpo.com/stephan-guyenet-debunks-gary-taubes/

Interesting how Stephan Guyenet says that:

I'd like to begin by emphasizing that carbohydrate restriction has helped many people lose body fat and improve their metabolic health. Although it doesn't work for everyone, there is no doubt that carbohydrate restriction causes fat loss in many, perhaps even most obese people. For a subset of people, the results can be very impressive.

From Stephan Guyenet

>This is where he should have mentioned leptin signaling, and the circuits in the brain that regulate body fat mass, which would have taken the book in a more compelling direction. According to literally thousands of publications spanning nearly two centuries, the brain is the only organ that is known to regulate body fat mass in humans and other animals-- neither fat tissue itself, nor the insulin-secreting pancreas have the ability to regulate body fat mass as far as we currently know. Leptin is the system that Drs. Jules Hirsch and Rudy Leibel have shown in carefully controlled human studies is responsible for the metabolic defect Taubes alluded to (1). It's also the system that is mutated in the genetically obese rodents he discusses (2, 3). Yet it receives no mention in the book. This is a fork in the road, where Taubes discards a solid hypothesis in favor of a shaky one.

From Wiki

Leptin (from Greek λεπτός leptos, "thin"), the "satiety hormone",[a] is a hormone made by adipose cells that helps to regulate energy balance by inhibiting hunger. Leptin is opposed by the actions of the hormone ghrelin, the "hunger hormone".

From Gary

>Another remarkable aspect of the last half-century of discussion about obesity and weight loss is that medical experts have been remarkably uninterested in the fat tissue itself and how our bodies happen to regulate it. With very few exceptions, they’ve simply ignored the fat tissue because they’ve already concluded that the problem is behavioral and lies in the brain, not in the body. Had we been discussing disorders of growth—why some people grow to be more than seven feet tall and others never make it to four feet—the only subject of discussion would be the hormones and enzymes that regulate growth. And yet, when we’re discussing a disorder in which the defining symptom is the abnormal growth of our fat tissue, the hormones and enzymes that regulate that growth are considered irrelevant.*

I think if you read the chapter on The Laws of Adiposity, you will see that Gary discusses much of what Anthony claims he doesn't.

I would cover the other points Stephan Guyenet makes but this would turn into an essay. Honestly he debunks nothing. I am curious if he ever read the book.

Buying a blood glucose meter is not an expensive investment (provided you don't really need it, ie. don't have diabetes) and it will pay dividends in terms of health. With a meter and about 200 strips and lancets, you can determine a big list of foods that raise your blood glucose and foods that don't. I've been customizing my meals based on what my glucose meter tells me raises my blood glucose the least and I am lo…

This is the first time I have heard glucose meters being used specifically for weight loss, very interesting. If this is a safe and effective way to encourage weight loss, this could be a huge business opportunity.

Continuous glucose monitoring (CGM) could be extremely effective for weight loss.

Dexcom has a CGM system that hooks up to your phone/watch, but is only available with prescription (and is extremely expensive without coverage), so this is effectively only available if you already have severe health problems.

Some former Dexcom employees founded a startup some time ago to do CGM for preventative healthcare, but I haven't heard anything of where it went. http://mobihealthnews.com/32601/dexcom-alums-develop-blood-s...

There are probably others.

To me these sorts of subcutaneous CGM systems seem more convenient for users than other initiatives (e.g, the contact lens projects). The sensor stays embedded for a week at a time, you can sleep with it in, and you get measurements every 5 minutes or so.

Well, I'd say that the endocrine reason sounds like a valid one. I can at least be counted in that group. Last December, I was diagnosed with T2 diabetes. After talking with a researcher about this (have worked with diabetes research school locally due to job), I came across a few things: 1. Damage is done to the pancreas at 140mg/dL 2. Too long at 140mg/dL or above can cause permanent damage to the pancreas. 3. Earl…

I think the problem with most sugars is that most people don't understand that the bulk of it is stored as glycogen in the muscular system. Sugars really only have several places to go once they are ingested: Held in the fiber of undigested food, blood stream, liver and muscles. We do really well with vegetables even though they are carbs since veggies are mostly fiber and very low carb. The high glycemic foods are o…

CHO storage in muscles and mostly kidney only amounts to about 2000kcal worth of energy. So there is a very high turnover and already over a week it's averaged out to the point where it doesn't really matter if what you eat is carbs or fat.

So for healthy, non-diabetic people it really doesn't matter.

(With the obligatory addendum that going all "low-carbs" or "keto" is a very, very bad idea if you expect to do any exercise at all)

Remember that relapse is part of recovery. Fall down seven, get up eight. Corny, but it got me through my hard times (and still does!)

DO NOT HAVE CHOCOLATE IN YOUR HOUSE. Ever. Even shitty chocolate. Even someone else's chocolate. If you know you'll binge on it, get rid of it.

Remember that chocolate will exist today, tomorrow, next week, next year. There will be a time in your life when you can eat chocolate again. For me, part of what always brought on bingeing was feeling like OH MY GOD I WILL NEVER EAT THIS FOOD AGAIN IN MY LIFEEEE. I had to, and still have to, remind myself that I can eat the food again so I don't have to EAT IT ALL RIGHT NOW OH GOD.

It seems like exposing your body to colder temperatures is a sure-fire way to increase your metabolism: http://www.theatlantic.com/magazine/archive/2015/01/does-glo... May be a little uncomfortable, but way better than screwing up your metabolism via extreme dieting. I'm consistently perplexed as to why the ice-vest-under-the-clothes weight loss method hasn't taken off yet.

Interesting. I read in Body By Science (McGuff) that drinking two liters of ice water a day will force your body to burn an additional 125 calories to maintain core temperature.

I know that since I've been following the weight-lifting protocol advocated by McGuff that my ability (and desire!) to sleep without covers, and skip wearing a coat in cooler weather, has increased.

So glycemic load is more or less glycemic index times carbohydrate density times the quantity of food you'd need to eat before feeling full?

In the other direction, see the documentary "Why Are Thin People Not Fat" where a group of thin volunteers are overfed by about double their normal calories for 4 weeks: http://news.bbc.co.uk/2/hi/uk_news/magazine/7838668.stm http://youtu.be/U1hbPXooB1U They all easily return to their starting weight, and at least one volunteer gains muscle but not fat. The body is amazing at maintaining homeostasis. Here's an nytime…

There's a lot of research being done right now, that suggests your gut microbiome has a lot to do with it. Very interesting stuff.
