A 2012 study published in the Journal of Medical Food found that raspberry ketone treatment, after a high-fat diet, can protect rats against nonalcoholic steatohepatitis, which is liver inflammation caused by a buildup of fat in the liver. Researchers reported that raspberry ketones had a dual effect of liver protection and fat reduction in the tested rats.
Twenty-five adult volunteers -- 15 of whom had been previously diagnosed with NAFLD -- participated in a low-calorie diet for eight weeks to lose up to 8 percent of their body weight. After weight loss, the volunteers were directed to maintain their weight for two years and to follow either a moderate- or high-protein diet averaging from 0.8 to 1 grams of protein per kilogram (2.2 pounds) of body weight. The research team took blood and urine samples and performed body scans to assess liver fat content and the amount of protein eliminated from the volunteers' bodies at three intervals: the start of the weight maintenance phase and again six months and then two years later.
Blood glucose concentrations are decreased during both exogenous and endogenous ketosis, although by different mechanisms. During endogenous ketosis, dietary carbohydrate deficit is the underlying cause of low blood glucose, along with reduced hepatic gluconeogenesis and increased ketone production (Cahill et al., 1966). With exogenous ketosis, carbohydrate stores are plentiful, yet ketones appear to lower blood glucose through limiting hepatic gluconeogenesis and increasing peripheral glucose uptake (Mikkelsen et al., 2015). One clinical use of the ketogenic diet is to improve blood glucose control, yet the elevated blood FFA may increase the risk of heart failure (Holloway et al., 2009). Thus, the ability of exogenous ketones to lower blood glucose without elevating blood FFA concentrations could deliver the desired effect of the diet, whilst also decreasing a potential risk.
Carbohydrates are your body's favorite fuel source; it breaks them down into glucose. Without a steady intake of carbohydrates, your body turns to using protein for fuel. But if you also are limiting how much protein you eat, your body is forced to burn stored fat as its primary source of fuel. That can result in weight loss, and ketones are a byproduct of burning fat.
While there are few superfoods proven to rev your metabolism, protein is one nutrient that actually may increase the amount of calories you burn. A study published in January 2012 in the Journal of the American Medical Association found that people who were fed more calories than they needed tended to have higher RMRs when they followed a normal- or high-protein diet compared with those who followed a low-protein regimen. For the best effects, Cederquist says, choose lean proteins, like chicken and fish, over fattier cuts, and consume smaller amounts throughout the day.
Ketones produced by the body are often associated with following a low-carbohydrate diet, according to the Better Health Channel. This is because the body breaks down sugars stored in the muscles when you do not eat enough carbohydrates. While dieting in general results in the release of some ketones, those following low-carbohydrate diets are likely to release a higher number of ketones.
Ketosis is a cornerstone of becoming Bulletproof; listen to these recent Bulletproof Radio episodes with ketosis experts Jimmy Moore and Dominic D’Agostino to get the scoop on how and why it works. It’s what happens when your body switches to burning fat instead of sugar for energy, and it only happens when you eat almost no carbohydrates, or when you hack it using certain kinds of oils.
In addition to decreasing serum ALT levels, weight reduction significantly decreased fasting insulin levels, and subsequent weight maintenance resulted in a sustained improvement (p = 0.03) (fig 3). In patients who regained weight, there was no significant change in fasting insulin levels between t = 0 and t = 15 months (p = 0.75) irrespective of the amount of exercise reported during the intervention. The amount of weight loss correlated with the reduction in fasting serum insulin levels (r = 0.46, p = 0.035) but not with the change in HOMA score (p = 0.72). Despite similar changes in weight, patients with HCV had a significantly greater decrease in fasting insulin during the initial three month period compared with non-HCV patients (p = 0.01) but there was no difference between groups at 15 months (p = 0.61).
Obesity is the result of an abnormal metabolism. Trying to lose weight without treating the metabolism will only produce a temporary result. The wrong question to ask is how to lose weight? The correct question is what is wrong in the metabolism; since the metabolism controls weight? The Weight Loss / Metabolism Correction treatment is revolutionizing, the way physicians battle the worldwide obesity epidemic. The advanced treatment is individualized and comprehensive to target weight loss at the metabolic level.
You can cut calories and keep your appetite in check by replacing candy and other high-sugar foods with complex carbohydrates. Fruit, vegetables and whole-grain varieties of bread, cereal and rice contain carbohydrates that take your body longer to use. Whole-grain cereals contain less added sugar than many processed cereals. Substituting white rice, which has a glycemic index of 89, with brown rice, with a glycemic of 50, can keep your blood sugar levels steady and reduce your urge to eat between meals, helping you lose weight.
Acetaminophen or Tylenol overdose, whether accidental or intentional, can cause acute liver failure. Emergent evaluation and treatment is required. Antidotes to protect the liver can be provided, but are effective only when used within a few hours. Without this intervention, acetaminophen overdose can lead to liver failure. Symptoms only occur after potential liver damage has occurred.
Forty three patients with hepatic steatosis seen in the liver clinic at Princess Alexandra Hospital between 1999 and 2000 were invited to participate in the study. Informed consent was obtained from each patient and the study protocol was approved by the hospital research ethics committee. Criteria for entry into the study were liver biopsy demonstrating ⩾grade 1 steatosis, overweight or obese (BMI ⩾25 kg/m2 in Caucasians and ⩾23 kg/m2 in Asians) or weight gain of >10% of usual body weight within 12 months, and alcohol consumption <10 g/day.
However, the ketones are highly concentrated in the lab studies and dosages are extremely high in the rodent studies, so it’s impossible to equate these findings to the efficacy of ketones for actual human consumption. Before we can make a clear recommendation for using raspberry ketones for weight loss, we need a lot more research, specifically involving humans using ketones alone.
When your body is severely deprived of energy (calories), it resorts to breaking down both fat and lean tissue (such as skeletal muscle) to generate fuel. Intuitively, the goal of a ketogenic diet is to increase body fat breakdown so it can be burned as fuel, but when you greatly restrict your calorie intake, you significantly increase lean tissue breakdown as well.
The increase in fractional catabolism of LDL apoB-100 with weight loss could involve multiple mechanisms, including a decrease in hepatic de novo cholesterol synthesis, in hyperinsulinemia, and in liver fat content. LDL receptor synthesis is regulated by a feedback mechanism linked to cellular cholesterol content (8). An improvement in insulin resistance decreases cholesterol synthesis, thereby increasing LDL receptor activity (7,8). RBP-4 levels are directly related to liver fat content (22), consistent with experimental data suggesting that impaired retinoic acid signaling can lead to hepatic steatosis (23), and this may involve inhibition of hepatic peroxisome proliferator–activated receptor-α. Hence, the inverse association we report between LDL apoB-100 FCR and RBP-4 may reflect changes in hepatic fat content, including decreased availability of cholesterol substrate, as well as fatty acids that per se can have a direct impact on cholesterol synthesis (24). Although plasma free fatty acid levels did not alter in our study, these may not reflect the corresponding portal or hepatic concentrations that regulate apoB-100 metabolism. Whether an LDL-lowering effect of RBP-4 with weight loss also involves a reduction in proprotein convertase subtilisin/kexin type 9 expression merits investigation (25). By decreasing VLDL triglycerides, weight loss leads to the formation of larger size LDL particles that are catabolized more rapidly (26). Increase in LDL size could also partially explain our finding of accelerated LDL apoB-100 FCR. However, changes in plasma lipid transfer protein activities with weight loss do not appear to contribute to the lipoprotein kinetic changes, consistent with reports indicating that plasma lipid transfer protein activities do not alter with weight loss (14). Despite a reduction in the hepatic secretion of VLDL apoB-100, we did not observe decreased production of LDL apoB-100. This result may be explained by our finding of increased conversion of VLDL to LDL apoB-100 and may be a consequence of increased lipoprotein lipase activity.
And recently, a six-year study involving 18,000 people with heart disease affirmed that for reducing LDL levels, the lower, the better. The study was reported at the annual meeting of the American Heart Association.3 Half the subjects lowered their LDL, on average, to 69; the other half reduced LDL to 54. Both groups were rewarded with few heart events over the six-year period, but the group with the lower LDL, 54, ended up the winner. It had 6.4% fewer events – heart attacks, heart disease deaths, strokes, bypass surgeries, stent procedures, and hospitalizations for severe chest pains – than the group with the higher LDL.
Fatty liver disease is a preventable illness with the promotion of a healthy lifestyle including a well-balanced diet, weight control, avoiding excess alcohol consumption and routine exercise program. These lifestyle modifications do not guarantee success in disease prevention as some people will develop fatty liver disease even with maximized lifestyle practices.
That was the bad news. But the good news is that it’s obviously still possible to lose weight anyway; after all, plenty of people do. Understanding the hormonal adaptations that make weight loss harder can help you make a plan for combating them, and at the very least the knowledge can help you be compassionate to your body: it’s only trying to keep you alive!
So the first step in keeping your metabolism high is proper fueling and not dramatically slashing calories. The average recreational female runner burns between 2,000 and 2,400 calories a day, while their male counterparts burn between 2,200 and 2,700. Following mainstream diets designed for sedentary people, which often recommend super low daily calorie intakes, will wreak mayhem on your active-person’s metabolism.
In an earlier study, we demonstrated that in the short term, weight loss reduced hepatic steatosis and fibrosis in patients with chronic HCV.11 In the current study, we demonstrated a similar early histological improvement in an additional small number of patients with obesity related fatty liver disease. Although liver biopsies were not performed at 15 months, it is likely that the sustained improvement in ALT and fasting insulin in patients who maintained weight loss was accompanied by a sustained reduction in hepatic steatosis and necroinflammatory activity. With long term weight maintenance there is likely to be an even greater resolution of hepatic fibrosis.
Two of the major sources of calories in the American diet are starch and sugar. Starches in the form of bread, pizza and pasta rank second, fifth and seventh on the list of the top 10 ways that Americans consume calories, according to registered dietitian Suzanne Boos. Sugars in the form of grain-based desserts and soda rank first and fourth. By cutting out sugar and starch for two weeks you can lose weight, even if you don't cut your calories.
As it turns out, how the sweet stuff affects your weight has a lot to do with what sugar-laden foods you eat, when you eat them, and what you pair them with, says dietician Georgie Fear, R.D., author of Lean Habits for Lifelong Weight Loss. So instead of forcing yourself through sugar withdrawals, adopt these sane, totally doable strategies to eat the sweet stuff and actually lose weight at the same time.
Hey Anita, your body actually can use both ketones and glucose for energy but your heart and brain actually prefer using ketones over glucose whereas your muscles and other organs go back and forth.

If you want to try a ketogenic diet, be aware that you'll have to adjust it for your individual metabolism and experiment with the right balance of carbs and calories. While some low-carbohydrate dieters find they are able to break stalls in their weight loss, others find that it is more difficult for them to stay in this state. You may want to consult a registered dietitian to build keto-friendly menus for you that will meet your nutritional needs. Be sure to keep your health care provider informed when you start a new diet, especially if you have ongoing health conditions.
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.
Although no specific treatment exists, weight loss can improve and possibly even reverse fatty liver disease to some degree. Shedding excess pounds through diet and exercise or with the help of weight-loss (bariatric) surgery can prevent additional liver damage when inflammation and scarring is already present. However, any weight loss should be gradual — no more than a few pounds a week — because losing weight too quickly can actually worsen fatty liver disease.
Background and aim: Obesity is a risk factor for progression of fibrosis in chronic liver diseases such as non-alcoholic fatty liver disease and hepatitis C. The aim of this study was to investigate the longer term effect of weight loss on liver biochemistry, serum insulin levels, and quality of life in overweight patients with liver disease and the effect of subsequent weight maintenance or regain.
Another factor to consider is that in nutritional ketosis the liver makes a steady supply of ketones and continuously releases them into the circulation. In contrast, most ketone supplement protocols involve bolus intakes that don’t mimic the endogenous release pattern. The extent to which this impacts metabolic and signaling responses across different tissues remains unclear.
All analyses were performed using SPSS version 15 (SPSS, Chicago, IL). Skewed data were log-transformed where appropriate. Treatment effects of the weight loss group relative to the weight maintenance group were analyzed using general linear modeling with adjustment for the dependent variable at baseline (i.e., end of study variable = baseline variable + treatment group + constant). Statistical significance was defined as P < 0.05.
Now let’s put this all together. Our “metabolism” is the fairly constant number of calories our bodies burn just existing at rest. But a far more interesting number is the calories our bodies burn during activity. Yes, changing body composition (adding muscle/losing fat) can change your metabolism a little, but a far greater impact on weight loss will be how many calories you expend (burn) during activity versus how many you eat during the day.
The digestion of meat and dairy are taxing on the liver when over-consumed. Eat them in smaller quantities to avoid overwhelming this important organ. Because the liver works like a filter, it can become clogged when we eat too much, too fast. The digestion of meat and dairy in particular produces byproducts that the liver must filter and eliminate from our bodies.
This is why you might realize you’ve put on weight even though your habits haven’t changed, or even if you’ve gotten healthier as you’ve gotten older. “Every few decades, women should be eating less than they did before,” says Bhatia. Specifically, the USDA recommends women aged 19 to 30 eat no more than 2,000 calories a day, but the number drops to 1,800 for women aged 31 to 50, then it shifts yet again to 1,600 for women 51 and over. So yes, the older you are, the more you may have to alter your lifestyle to account for your metabolism. The good news is that when you’re eating a lot of fresh, wholesome foods, you should still be able to stick within those calorie bounds and feel satiated.
There are only about 30 metabolic chambers in the world, and the NIH is home to three. These highly sensitive, multimillion-dollar scientific instruments are considered the gold standard for measuring metabolism. They’ve furthered our understanding of obesity, metabolic syndrome, and diabetes — diseases that are now among the greatest threats to health worldwide — by letting researchers carefully track how individual bodies respond to the calories they’re offered.
