New research8 published in the journal Obesity affirms that the hungrier we are, the worse off our weight-loss efforts are. “The few individuals who successfully maintain weight loss over the long term do so by heroic and vigilant efforts to maintain behavior changes in the face of increased appetite,” summed up lead author Dr. Kevin Hall and colleagues from the National Institute of Diabetes and Digestive and Kidney Diseases.
Calorie density is the concentration of calories in any given volume of food. Certain foods have more calories packed into them – bite for bite or pound for pound – than others. Tomatoes, for example, have about 90 calories per pound. Bagels pack in more than 1,200 calories per pound. (It’s obvious that the bagels are higher – a lot higher – in calorie density.)
My case was a quandary: I already exercised diligently, running about four miles most days. I had long ago given up red meat and most cheese. Yet my bad cholesterol last October was 169, way above my recommended high of 130 and an optimal 100. (People’s LDL goals depend on their number of risk factors such as smoking, diabetes or high blood pressure.)
I practice a Cyclical Ketogenic diet where I incorporate a higher carb day once a week. The day following a higher carb day, I follow an intermittent fasting day where I do not eat anything (no fats either) for 20-24 hours. I do this as a cellular cleanse (autophagy) as well as a way for my body to get back into ketosis. Would it be helpful to add an exogenous ketone on this particular “fasting” day to get into ketosis quicker? Would I notice better results or is my own nutritional ketosis enough? I am relatively fit with a pretty low fat percentage for my gender and age, but I am always striving for an even leaner “more chiseled” look.
And you don’t need a history of weight problems to experience these feelings of inadequacy. Celebrities and big businesses — like Goop and Dr. Oz and many of the supplement, wellness, and exercise companies out there — have minted billions off stoking our anxieties about our physical shortcomings. If we only tried a new exercise, bought a new gizmo, or ate a certain way, they suggest, we’d be slimmer, glowier, healthier.
Your body needs a small amount of cholesterol. But many people have too much, especially the “bad” kind, or LDL cholesterol. That can happen if you eat too much saturated fat, found mainly in foods from animals. If your LDL level is too high, plaque can build up in your heart's arteries and lead to heart disease. The “good” cholesterol, HDL, helps clear LDL from your blood.
High protein diets, such as the Atkin's diet or the Paleo diet, have been popular weight-loss programs in recent years. A high-protein diet has created concern, however, because it is high in meat, animal products, and saturated fat. Numerous studies have shown that a high meat intake is associated with increased risk for heart disease, cancer of the digestive tract, overall mortality, and acceleration of chronic kidney disease, kidney stones, and osteoporosis.1
Exercise diaries were not available for two patients. Before commencement of the programme only 10 patients (29%) were involved in any form of regular exercise (range 40–350 min/week). From t = 0 to t = 3 months, all patients except two (6%) commenced regular weekly aerobic activity with mean exercise time of 214 (166) minutes per week (range 0−840 min/week). During the 12 month weight maintenance programme, overall exercise decreased to a mean of 120 (140) min/week (range 0–560 min/week). In those patients who maintained weight, exercise levels were sustained at recommended levels of 150 (160) min/week whereas those that regained weight had reduced their level of exercise to 50 (54) min/week (p = 0.02).
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
A recent study of adults with NAFLD suggests that vigorous physical activity may also help reduce damage from fatty liver disease. Government guidelines advise that healthy adults get at least 150 minutes per week of moderate physical activity, such as walking, or 75 minutes of vigorous physical activity, such as running on a treadmill. Increasing that time to 300 minutes of moderate physical activity or 150 minutes of vigorous physical activity each week can yield even greater benefits, such as weight loss. But if you don't already exercise regularly, talk with your doctor first about the best way to start.
Nonalcoholic fatty liver disease (NAFLD) — a condition in which excess fat accumulates in the liver of people who drink little or no alcohol — has become one of the most common liver diseases in the U.S. It's estimated that the disorder affects up to 20 percent of American adults. Researchers believe this is associated with rising rates of obesity. While some studies have shown a benefit from vitamin E and the prescription medication pioglitazone, the focus is generally on treating the risk factors.
Summer is upon us and this often causes stress for many people battling weight issues. One of the most overlooked underlying causes of weight loss resistance is a liver that is over burdened with toxins. Bringing health and balance back to the liver is often the missing key to sustained weight loss. Read on to find out how the liver causes unwanted weight gain, how to know if your liver is toxic and what to do about it!

I also found out that I’m bad at estimating my calorie consumption. During my chamber stay, I told a nutritionist what I’d eaten the day before and filled in a survey of my food consumption over the past year. Based on that, she’d calculated I was eating only 1,500 to 2,000 calories per day. I thought I was being incredibly thorough and generous in my accounting, but if this was really all I ate, I’d be thinner than I am.
The other factor significantly associated with maintenance of weight loss was insulin resistance. Weight regain was inversely associated with insulin resistance—that is, less regain was observed in patients with higher HOMA and fasting insulin levels. Although controversial, a number of studies in different population groups have shown that hyperinsulinaemia predicts a reduced weight gain over time and may be an adaptation for weight maintenance.29,30 The mechanisms linking the association between insulin resistance and weight gain remain to be determined but this factor may be useful for predicting those patients at higher risk of weight regain after lifestyle interventions.
The problem? Exogenous ketone supplements work by flooding your bloodstream with ketones. But unless you’re also eating a ketogenic diet (and producing a steady stream of ketones naturally), those supplemental ketones won’t stick around forever. “The benefit of exogenous ketones is limited due to their excretion through the urine,” explains Madge Barnes, MD, family medicine specialist with Texas Health Family Care. In other words? They’ll only work for a few hours until you pee them out. As a result, you need to keep on supplementing—which can get expensive. Twenty single-serving packets of Prüvit’s Keto//OS MAX Pure Therapeutic Ketones, for example, cost $130. (The company doesn’t specify how often you should take them.)
There’s also the issue of supplement safety in general. All supplements—whether you’re talking about vitamins, minerals, herbs, or other nutritional mixes—are only loosely regulated. “We know that there is contamination of supplements here in the U.S., often from products that are manufactured abroad,” Palumbo says. In that case, “the same concerns apply to this as for any other supplement.”
Seemingly sugar is added to nearly all packaged foods; not even peas are safe. The green beans appear to have been saved the same sugary water fate and the tin says it contains only green beans and water – which is what I’d expect. I opt for a trout fillet and head back to the office. That’s about as good as it gets when it comes to an improvised sugar-free lunch.
In the context of weight loss, metabolism is considered how fast and how many calories you burn daily, therefore theoretically, metabolism should dictate how quickly or easy it would be for someone to lose, gain or control their weight. Unfortunately, fast and slow resting metabolisms are more of a myth than reality. Although two people of the same weight, height and body composition may burn calories at a slightly different rate, the difference is so small it’s virtually insignificant in the big picture. And no matter who you are, the heavier the body, the more calories it burns in all activities. Contrary to what most people believe, we do have control over our metabolism and how fast we lose weight. As an example, simply standing up instead of sitting burns more calories, so minimizing time spent sitting will boost your overall metabolism. If you start walking or doing any activity on a regular basis, your metabolism will increase significantly.
There were limitations with these studies, mainly that they were "free living." That means participants were told what to do, and the researchers assumed they did it. Fortunately, a study published in the University of Minnesota's Journal of Nutrition was much more tightly controlled. For the first 12 weeks of the study, the participants had every meal they consumed prepared by the university, significantly reducing the probability of data interference. After the 12 weeks, the subjects were told to continue the diet on their own for 24 more weeks on their own. Each group lost the same amount of weight and body fat—regardless of how much sugar they consumed.
As you might expect, I felt great for the first few days. The key word there is “felt.” A couple of days wasn’t long enough for the change to have had a physical effect or move the needle on the scale. Maybe it would have if I’d been eating nothing but fast food for three meals a day. But I had gotten so excited at the prospect of cutting back on my sweet tooth that it boosted my motivation. At the end of the 30 days, however, I didn’t end up feeling any different.
A 2001 study published in International Journal of Obesity followed overweight subjects whose diets derived either 10 or 5 percent of calories from sucrose. On a 2,000-calorie diet, this would be the difference between 50 and 25 grams of sugar per day. After eight weeks, there were no significant differences in weight loss or BMI. In fact, the high-sugar group lost about 1-1/2 pounds more, but this effect was statistically insignificant.
Hello! We have a section on this in our weight loss plateau post—it’s fine to use them, but be careful if you have any digestive issues as a result of them, and make sure they’re not interfering with your weight loss goals. “In addition to potentially contributing too many calories, sources of fat like coconut oil (including concentrated supplements) contain medium chain triglycerides (MCT). These cannot be stored in body fat, meaning that whatever is consumed has to be promptly burned for energy. So you’re adding these sources on top of your dietary fat consumption for satiety, this type of fat takes priority. Often times people fall into the trap of adding supplements of coconut oil or straight up MCT oil and it ends up adding extra calories. Yes, it may raise your ketones a bit, but the overall cost may impact your weight loss.”
Thanks to my personal experience and Dr. Berkson, I know firsthand how important the liver is to health, metabolism and the ability to lose weight, create cellular energy, burn fat and detoxify the body. So when a doctor I know and respect, Alan Christianson, NMD, came out with a new book about the importance of the liver in metabolism, The Metabolism Reset Diet (Harmony, January 2019), I paid particular attention.
Testing ketones can indicate whether or not you need to make adjustments to your diet, or can simply confirm you are on the right track. Many keto dieters find them to be motivating when they see the color indicating a job well done. If the ketone strips don’t show ketosis, it’s a good idea to re-examine your diet to search for hidden carbs which may be keeping you out of ketosis and stalling weight loss.
The ketosis produced by fasting or limiting carbohydrate intake does not have negative effects for most people once the body has adapted to that state. The ketosis caused by diet has been referred to as dietary ketosis, physiological ketosis, benign dietary ketosis (Atkins), and, most recently, nutritional ketosis (Phinney and Volek), in an attempt to clear up possible confusion with diabetic ketoacidosis.
Still, it is important to recognize that some fruits, like papaya, pineapple, and mango, are higher in natural sugars than other types of fruit. That’s not an issue for most people, but those with type 2 diabetes should be mindful of portion size with these kinds of fruits, due to their potential to spike blood sugar. Fruits like raspberries, apples, and oranges have a relatively lower risk of throwing blood sugar levels out of whack.
The catabolic changes in HDL with weight loss could relate to an increase in HDL particle size, which in turn may be a consequence of a reduction in the plasma VLDL triglyceride pool available for exchange with HDL (27). Increased adiponectin can inhibit hepatic lipase activity (28), which could account for the partial correlation in our study between changes in plasma adiponectin and HDL apoA-I FCR. A “balancing feedback” mechanism probably accounts for the tight correlation between changes in catabolism and production of HDL apoA-I after weight loss. Furthermore, the fact that HDL underproduction offset the HDL-elevating effect of depressed HDL catabolism could in part reflect the impact of lowered dietary fat intake on the hepatic expression and secretion of apoA-I (29). However, we found no significant correlation between the changes in HDL apoA-I production rate and dietary saturated fat intake in our weight loss group. That there was no significant correlation between the changes in LDL and HDL FCR suggests that different mechanisms underlie these alterations in lipoprotein metabolism after weight loss.
Overweight and obese individuals are at risk for higher levels of cholesterol in their blood, which increases their risk for cardiovascular disease. For this reason, weight loss is often recommended to help lower cholesterol. While weight loss is an effective tool at lowering cholesterol, it may temporarily raise cholesterol, although this effect is not permanent.
“I always tell clients to balance their carb and sugar intake with protein, fiber, and [or] healthy fats,” says Fear. All three of these nutrients slow the absorption of sugar into your bloodstream, which decreases the spike and crash in your blood sugar and your energy levels, she says. That means you won't feel weak, shaky, or hangry 30 minutes after you eat.
The empty calories in sugar-sweetened drinks, such as soda, fruit punch or sweet tea, can add up to weight gain. A can of soda contains about 38 grams of sugar and 150 calories. If you are accustomed to drinking two cans per day, eliminating soda and switching to water could cause you to lose about 2 pounds per month without changing your diet otherwise. One reason for the increase in child obesity in the United States is that children consume more than 11 percent of their calories from sugary drinks, according to the University of Rochester Medical Center's Rae-Ellen Kavey, MD, MPH.
I've never been able to do that before in my life. and for once in my life, I truly believe in myself. I don't know that I ever did before, at least not without someone else to reassure me of it. I'm happy to say that my outlook on life has changed drastically. Every day it seems to get a little easier to stay positive and to love and live for myself. I'm down just over 12lbs in 2 weeks, following this weight loss program: http://the2weekdietnow.com/lose-weight
To determine the reason for the differences in blood d-βHB concentration, the KE and KS drinks were analyzed for enantiomeric purity. The KE contained >99% of the d-isoform, whereas ~50% of the KS βHB was the l-isoform (Figure (Figure1D).1D). Plasma samples from participants who consumed the high dose KS drink (n = 5) were analyzed to reveal higher l-βHB than d-βHB, the total βHB Cmax being 3.4 ± 0.2 mM (Figure (Figure1E),1E), with a total βHB AUC of 549 ± 19 mmol.min. After 4 h, plasma l-βHB remained elevated at 1.9 ± 0.2 mM; differences in urinary excretion of the two isoforms could not explain this observation as both d- and l-βHB were excreted in proportion to their blood AUCs (Figure (Figure1F).1F). Therefore, in order to determine the time required for l-βHB elimination, a follow-up experiment was undertaken in which subjects (n = 5) consumed 3.2 mmol.kg−1 of βHB as KE and KS with hourly blood and breath sample collection up to 4 h, plus additional samples at 8 h and 24 h post-drink. l-βHB was found to be 1.1 ± 0.1 mM at 4 h, and 0.7 ± 0.2 mM after 8 h, but undetectable after 24 h (Figure 1G). Low amounts of d-βHB (0.3 ± 0.1 mM) were present at 24 h, presumably due to endogenous production. Both ketone drinks significantly increased breath acetone concentration, but at a slower rate than blood d-βHB, reaching a peak after 3 h that was twice as high following the KE (87 ± 9 ppm) than the KS (44 ± 10 ppm), suggesting that d-βHB was readily converted to acetone, but l-βHB was not (p < 0.005, Figure Figure1H1H).
Until there is more definitive information on the necessary blood levels and the differing proportions of BOHB an AcAc to optimize cellular and organ functions, it will be difficult to specify the dosing and duration of supplemental ketones. However for fuel use, and very likely for exercise performance as well, sustained blood levels of BOHB in the range of 0.5 mM to 1.0 mM are likely to be required. This is achieved physiologically by an estimated ketone production of 50-100 grams per day in a keto-adapted human.
Each liver disease will have its own specific treatment regimen. For example, hepatitis A requires supportive care to maintain hydration while the body's immune system fights and resolves the infection. Patients with gallstones may require surgery to remove the gallbladder. Other diseases may need long-term medical care to control and minimize the consequences of their disease
The issue with these studies involving rodents is that the doses are very high; in fact, the equivalent dose in humans is 100 to 300 milligrams a day, which is over 200 times greater than the average daily intake of raspberry ketones! This is a worrisome dosage, especially when compared to other fat-burning supplements that are on the market today. So although this study suggests that raspberry ketones may help to reduce liver inflammation, more studies need to be done on humans using the appropriate dosage. (5)
Pick up the weights. "Physical activity is one of the few ways that metabolism can be significantly impacted, both because being active requires additional energy and because of the shift in body composition," Knott says. Instead of focusing only on cardio exercise, add weight-bearing activities too. Cardio may give you a higher total calorie burn, but that means you lose fat and muscle. Add two to three days of strength training per week to help lose fat but preserve muscle. "More muscle mass means a higher metabolism, so don't be afraid of weight training," Anzlovar says.

But, Bustillo cautions against hanging too much hope on this: “Many companies that sell the ‘after burn’ or ‘metabolic workouts’ are just utilizing a marketing strategy with [a grain of science behind it],” he says. “They're not technically lying, because training can increase BMR [in the 24 hours post-workout], but it's not by more than 200-300 calories on average.”
Instead pay attention to the quality of your diet. Research shows that eating a healthy diet rich in whole, unprocessed foods will help fuel your activity and keep your metabolism humming along. If you doubt it can make a big difference, consider that a study published in Food & Nutrition Research found that volunteers burned nearly twice as many calories (137 vs. 73) after eating a cheddar cheese sandwich on multi-grain bread than they did eating the same calories from a processed cheese sandwich on white bread. Quality matters.

At age 34 and 5-foot-9, my weight hovers in the 150s, and my BMI is normal. But even as a child, I was chubby and seemed to enjoy sugary and fatty foods more than other members of my family. During my late teens and 20s, I struggled to manage my weight and was at times overweight — a situation that worsened at the end of high school. I moved to Italy and indulged in all the pizza, ice cream, carpaccio, and mozzarella my little town in Abruzzo had to offer. Like a research mouse, I puffed out and returned to Canada the following year depressed about my body. It took several years to really start the process of slimming down.
