Long-term weight loss: Secrets from people who have kept …

Jan, 14th 2019 2:42 pm, Article Recommended by Dr. J. Smith

Most people who diet will regain 50 per cent of the lost weight in the first year after losing it. Much of the rest will regain it in the following three years.

Most people inherently know that keeping a healthy weight boils down to three things: eating healthy, eating less, and being active. But actually doing that can be tough.

We make more than 200 food decisions a day, and most of these appear to be automatic or habitual, which means we unconsciously eat without reflection, deliberation or any sense of awareness of what or how much food we select and consume. So often habitual behaviours override our best intentions.

A new study has found the key to staying a healthy weight is to reinforce healthy habits.

Imagine each time a person goes home in the evening, they eat a snack. When they first eat the snack, a mental link is formed between the context (getting home) and their response to that context (eating a snack). Every time they subsequently snack in response to getting home, this link strengthens, to the point that getting home prompts them to eat a snack automatically. This is how a habit forms.

New research has found weight-loss interventions that are founded on habit-change, (forming new habits or breaking old habits) may be effective at helping people lose weight and keep it off.

We recruited 75 volunteers from the community (aged 18-75) with excess weight or obesity and randomised them into three groups. One program promoted breaking old habits, one promoted forming new habits, and one group was a control (no intervention).

The habit-breaking group was sent a text message with a different task to perform every day. These tasks were focused on breaking usual routines and included things such as drive a different way to work today, listen to a new genre of music or write a short story.

The habit-forming group was asked to follow a program that focused on forming habits centred around healthy lifestyle changes. The group was encouraged to incorporate ten healthy tips into their daily routine, so they became second-nature.

Unlike usual weight-loss programs, these interventions did not prescribe specific diet plans or exercise regimes, they simply aimed to change small daily habits.

After 12 weeks, the habit-forming and habit-breaking participants had lost an average of 3.1kg. More importantly, after 12 months of no intervention and no contact, they had lost another 2.1kg on average.

Some 67 per cent of participants reduced their total body weight by over 5 per cent, decreasing their overall risk for developing type two diabetes and heart disease. As well as losing weight, most participants also increased their fruit and vegetable intake and improved their mental health.

Habit-based interventions have the potential to change how we think about weight management and, importantly, how we behave.

The habits in the habit-forming group, developed by Weight Concern (a UK charity) were:

1. Keep to a meal routine: eat at roughly the same times each day. People who succeed at long term weight loss tend to have a regular meal rhythm (avoidance of snacking and nibbling). A consistent diet regimen across the week and year also predicts subsequent long-term weight loss maintenance.

2. Go for healthy fats: choose to eat healthy fats from nuts, avocado and oily fish instead of fast food. Trans-fats are linked to an increased risk of heart-disease.

3. Walk off the weight: aim for 10,000 steps a day. Take the stairs and get off one tram stop earlier to ensure youre getting your heart rate up every day.

4. Pack healthy snacks when you go out: swap crisps and biscuits for fresh fruit.

5. Always look at the labels: check the fat, sugar and salt content on food labels.

6. Caution with your portions: use smaller plates, and drink a glass of water and wait five minutes then check in with your hunger before going back for seconds.

7. Break up sitting time: decreasing sedentary time and increasing activity is linked to substantial health benefits. Time spent sedentary is related to excess weight and obesity, independent of physical activity level.

8. Think about your drinks: choose water and limit fruit juice to one small glass per day.

9. Focus on your food: slow down and eat while sitting at the table, not on the go. Internal cues regulating food intake (hunger/fullness signals) may not be as effective while distracted.

10. Always aim for five serves of vegetables a day, whether fresh, frozen or tinned: fruit and vegetables have high nutritional quality and low energy density. Eating the recommended amount produces health benefits, including reduction in the risk of cancer and coronary heart disease.

8. Obesity Management for the Treatment of Type 2 Diabetes …

Jan, 12th 2019 2:43 pm, Article Recommended by Dr. J. Smith


8.11 Metabolic surgery should be recommended as an option to treat type 2 diabetes in appropriate surgical candidates with BMI 40 kg/m2 (BMI 37.5 kg/m2 in Asian Americans) and in adults with BMI 35.039.9 kg/m2 (32.537.4 kg/m2 in Asian Americans) who do not achieve durable weight loss and improvement in comorbidities (including hyperglycemia) with reasonable nonsurgical methods. A

8.12 Metabolic surgery may be considered as an option for adults with type 2 diabetes and BMI 30.034.9 kg/m2 (27.532.4 kg/m2 in Asian Americans) who do not achieve durable weight loss and improvement in comorbidities (including hyperglycemia) with reasonable nonsurgical methods. A

8.13 Metabolic surgery should be performed in high-volume centers with multidisciplinary teams that understand and are experienced in the management of diabetes and gastrointestinal surgery. C

8.14 Long-term lifestyle support and routine monitoring of micronutrient and nutritional status must be provided to patients after surgery, according to guidelines for postoperative management of metabolic surgery by national and international professional societies. C

8.15 People presenting for metabolic surgery should receive a comprehensive readiness and mental health assessment. B

8.16 People who undergo metabolic surgery should be evaluated to assess the need for ongoing mental health services to help them adjust to medical and psychosocial changes after surgery. C

Several gastrointestinal (GI) operations including partial gastrectomies and bariatric procedures (35) promote dramatic and durable weight loss and improvement of type 2 diabetes in many patients. Given the magnitude and rapidity of the effect of GI surgery on hyperglycemia and experimental evidence that rearrangements of GI anatomy similar to those in some metabolic procedures directly affect glucose homeostasis (36), GI interventions have been suggested as treatments for type 2 diabetes, and in that context they are termed metabolic surgery.

A substantial body of evidence has now been accumulated, including data from numerous randomized controlled (nonblinded) clinical trials, demonstrating that metabolic surgery achieves superior glycemic control and reduction of cardiovascular risk factors in patients with type 2 diabetes and obesity compared with various lifestyle/medical interventions (17). Improvements in micro-vascular complications of diabetes, cardiovascular disease, and cancer have been observed only in nonrandomized observational studies (4453). Cohort studies attempting to match surgical and nonsurgical subjects suggest that the procedure may reduce longer-term mortality (45).

On the basis of this mounting evidence, several organizations and government agencies have recommended expanding the indications for metabolic surgery to include patients with type 2 diabetes who do not achieve durable weight loss and improvement in comorbidities (including hyperglycemia) with reasonable nonsurgical methods at BMIs as low as 30 kg/m2 (27.5 kg/m2 for Asian Americans) (5461). Please refer to Metabolic Surgery in the Treatment Algorithm for Type 2 Diabetes: A Joint Statement by International Diabetes Organizations for a thorough review (17).

Randomized controlled trials have documented diabetes remission during postoperative follow-up ranging from 1 to 5 years in 30%63% of patients with Roux-en-Y gastric bypass (RYGB), which generally leads to greater degrees and lengths of remission compared with other bariatric surgeries (17,62). Available data suggest an erosion of diabetes remission over time (63): 35%50% or more of patients who initially achieve remission of diabetes eventually experience recurrence. However, the median disease-free period among such individuals following RYGB is 8.3 years (64,65). With or without diabetes relapse, the majority of patients who undergo surgery maintain substantial improvement of glycemic control from baseline for at least 5 (66,67) to 15 (45,46,65,6870) years.

Exceedingly few presurgical predictors of success have been identified, but younger age, shorter duration of diabetes (e.g.,

Beyond improving glycemia, metabolic surgery has been shown to confer additional health benefits in randomized controlled trials, including substantial reductions in cardiovascular disease risk factors (17), reductions in incidence of microvascular disease (74), and enhancements in quality of life (66,71,75).

Although metabolic surgery has been shown to improve the metabolic profiles of patients with type 1 diabetes and morbid obesity, establishing the role of metabolic surgery in such patients will require larger and longer studies (76).

Metabolic surgery is more expensive than nonsurgical management strategies, but retrospective analyses and modeling studies suggest that metabolic surgery may be cost-effective or even cost-saving for patients with type 2 diabetes. However, results are largely dependent on assumptions about the long-term effectiveness and safety of the procedures (77,78).

Diet & Weight Loss

You want to lose weight fastis it possible to crash diet safely? Dietitian Christy Brissette reveals how you can without harming your metabolism.

Face it, if you want to lose weight over the long haul, your best bet is to make sustainable, long-term lifestyle changes like the nine simple ones this woman made to shed 45 pounds and keep them off. But sometimes life comes at you fast and you need a fast solution. One smart lifestyle change is to eat plenty of veggiesespecially for someone looking to lose weight. Vegetables are nutrient-packed and provide plenty of filling fiber with hardly any calories. Plus, non-starchy veggies have a high water content, so they hydrate you while filling you upthe perfect combination for weight loss.

Starchy veggies (like potatoes) and processed whole grains (like whole-wheat bread) are foods Id normally recommend eating in moderation, since they provide plenty of nutrients, fiber, and healthy carbs. However, high-carb foods arent your best friend when youre looking to drop water weight. Essentially, when your body stores excess carbs, it stores them with water. So replacing carb-heavy foods with non-starchy veggies that still provide filling fiber without as much water retention is the way to go. For a week before your event, you can swap out the starchy carbs for more non-starchy vegetables to lose some water weight. (These are 10 things experts wish you knew about water weight.)

Aim for filling at least half of your plate with non-starchy veggies like asparagus, peppers, broccoli, cauliflower, mushrooms, spinach, kale, cucumbers, and more. This is a great idea for everyones health, not just people wanting to lose weight.


Another healthy change that will help you look better is to cut back on salt. Sodium causes your body to hold onto excess water, so eating a high-salt diet means youre likely storing more water weight than necessary. Check to see if you have any of the seven clear signs youre eating too much salt. If youre in a rush to lose weight fast, cut out added salt as much as possible. That means keep ditching the salt shaker and avoiding processed and packaged foods, where added salt is pretty much inevitable.

Try making food from scratch rather than eating out before your big event to further limit sodium and fight bloat. Even at healthier restaurants, sodium levels tend to be through the roof.

Avoiding salt doesnt mean your food has to be bland. Experiment with using different herbs and spices. Try adding fresh cilantro and cumin to grilled fish, lemon and rosemary to chicken, or ginger and Chinese five spice to tempeh or beef. Pick up some spice blends from your local market to help add more spice to your life just read the ingredients and make sure theres no salt added.

It seems counterintuitive to drink lots of water when youre looking to lose weight fastespecially water weightbut staying hydrated is one of the most important steps you can take to lose weight. People often mistake thirst for hunger, so staying hydrated allows you to be more in touch with the times when you are actually hungry, rather than just thirsty. Plus, a lot of good things happen to your body when you drink enough fluids.

Drinking water before you eat has also been shown to lead to increased weight loss by decreasing the amount you eat at meals. Its hard for your eyes to be bigger than your stomach when youre already full from downing plenty of water! Staying hydrated also promotes good digestion, so youre less likely to end up backed up and bloated.

Keep a water bottle with you at all times and aim for drinking eight-plus cups a day. Eliminate sugary beverages like soda, juice, or sweetened coffee or tea since theyre calorie bombs without much nutritional benefit. Throw in lemon slices or chopped fruit and herbs to your water to add flavorit will encourage you to drink more!

Your brain also has its own senseof what you should weigh,no matter what you consciously believe.This is called your set point,but that’s a misleading term,because it’s actually a rangeof about 10 or 15 pounds.You can use lifestyle choices to move your weightup and down within that range,but it’s much, much harder to stay outside of it.The hypothalamus, the part of the brainthat regulates body weight,there are more than a dozen chemical signalsin the brain that tell your body to gain weight,more than another dozen thattell your body to lose it,and the system works like a thermostat,responding to signals from the bodyby adjusting hunger, activity and metabolism,to keep your weight stable as conditions change.That’s what a thermostat does, right?It keeps the temperature in your house the sameas the weather changes outside.Now you can try to change the temperaturein your house by opening a window in the winter,but that’s not going to changethe setting on the thermostat,which will respond by kicking on the furnaceto warm the place back up.Your brain works exactly the same way,responding to weight loss by using powerful toolsto push your body backto what it considers normal.If you lose a lot of weight,your brain reacts as if you were starving,and whether you started out fat or thin,your brain’s response is exactly the same.We would love to think that your brain could tellwhether you need to lose weight or not,but it can’t.If you do lose a lot of weight,you become hungry,and your muscles burn less energy.Dr. Rudy Leibel of Columbia Universityhas found that people who have lost10 percent of their body weightburn 250 to 400 calories lessbecause their metabolism is suppressed.That’s a lot of food.This means that a successful dietermust eat this much less foreverthan someone of the same weightwho has always been thin.

Human Chorionic Gonadotropin (HCG) – a natural hormone produced by the placenta during pregnancy unchanged in urine output and processed for the production of drugs. As a pharmaceutical preparation (lyophilized injectables), it is widespread in the traditional and sport medicine: applied on the testimony of menstrual disorders in women to androgen deficiency in men.

Chemically hCG (human Chorionic Gonadotropin) is a glycoprotein consisting of a (alpha) and b (beta) subunits: a-subunit is identical with those of the TSH (thyroid stimulating hormone), FSH (follicle stimulating hormone) and LH (luteinizing hormone) and b -subunit is unique. Structurally, it consists of a sequence of 237 amino acids.

By action, Gonadotropin is a multifunctional hormone: it possesses the biological properties of both FSH and LH, binding to both types of gonadotropic receptors; but! Luteinizing properties in it are predominant – they exceed those of the luteinizing hormone itself.

The effects of the Gonadotropin as a pharmaceutical formulation for men – stimulation of the synthesis of sex hormones in testes, increasing spermatogenesis, improved erectile function, increasing libido, sexual organs and the development of secondary sexual characteristics; For women – stimulation of the synthesis of sex hormones in the ovaries and progesterone in the yellow body, provoking ovulation, maintaining the development of the placenta.

The Gonadotropin hormone is produced only in the body of women, but this does not negate its effectiveness for men. It starts to be produced in the tissues of the chorion for about 7 days after fertilization of the ovulum, acting as a key indicator of the presence and safe passage of pregnancy. Its maximum concentration is observed at 7-11 weeks of pregnancy, after which it slowly but irreversibly decreases.

The average recommended HCG dosage for athletes is 500-1500 IU per week. For an even action background, a weekly dose is usually divided into injections on equidistant days: for example, 500 IU are injected on Wednesdays and Saturdays.

The use of Gonadotropin is effectively connected to steroid cycles (starting from the middle or closer to the end of the cycle and lasting at least 3 weeks), rather than on post-cycle therapy (at the end of the cycle). The expediency of its use on PCT raises doubts, because by that time complications can already form and not give in to treatment with Gonadotropic drugs.

It is important to understand that HCG injections are justified to prevent side effects of anabolic steroids (as the suppression of production of Testosterone and the resulting testicular atrophy, oligospermia, decrease in libido and erectile function).

Athletes who are correctly administering Gonadotropin leave only positive reviews, but warn that when abused, it is capable of provoking side effects. Probable acne, increased aggression, water retention, coarsening of the voice, high blood pressure, gynecomastia and others, typical of Testosterone disorders. This is due to the specific action of the drug.

In sports, before using human Chorionic Gonadotropin (hCG), it is recommended to consult a specialist to exclude contraindications: hypersensitivity, allergic reactions, and sex hormone dependent tumors – in both sexes; Ovarian hyperstimulation syndrome – in women; Inguinal hernia, operations in the groin and the wrong position of the testicles – in men.

You can buy HCG economically and safely in our online steroid store. Working for clients from all over the World, provides a wide range of products and comfortable conditions for their purchase.

Key to long-term weight loss may be as simple as more fat …

Jan, 6th 2019 11:43 am, Article Recommended by Dr. J. Smith

Losing weight is hard work, but many people who have lost weight may agree that keeping it off can be an even greater challenge.

A lack of self-control or a few too many dietary indulgences are often cited as reasons for regaining weight. But a new study in the November issue of BMJ questions this conventional view, finding that the type of calories you consume may influence how likely you are to keep that weight off for the long term.

The human body is designed to protect itself when it sheds weight, whether voluntarily or involuntarily, by increasing the urge to eat while slowing down the metabolism and more efficiently storing fat. Although it may be exciting to see the numbers on the scale drop, this makes it harder to keep losing weight or even maintain weight loss.

The purpose of the BMJ study was to see if different levels of carbohydrates in the diet could prevent these metabolic changes from occurring, so that weight lost might stay off. The focus on carbohydrates was based on the carbohydrate-insulin model of obesity, which holds that high insulin levels that result from eating a high glycemic load diet (i.e., highly processed carbohydrates like refined breads, crackers, cookies, and sugars) cause energy from the food to be stored more easily as fat, and may increase hunger and food cravings, lower energy expenditure, and promote weight gain.

This study raises the possibility that a focus on restricting carbohydrates, rather than calories, may work better for long-term weight control.

David Ludwig

Participants were first placed on a diet to lose about 12 percent of their starting weight (weight loss averaged 25 pounds) to kickstart metabolic changes. The next phase randomly assigned the 164 participants who achieved this loss to one of three test groups:

The protein amount was the same in all groups, at 20 percent. Total calories were adjusted up or down in each participant to prevent any weight changes. All meals were provided to the participants during the weight-loss phase and throughout the 20-week test phase. The types of foods in each diet group were designed to be as similar as possible, but varying in amounts: The high-carbohydrate group ate more whole grains, fruits, legumes, and low-fat dairy products, while the low-carbohydrate group ate more fat but eliminated all grains and some fruits and legumes.

After participants followed the diets for 20 weeks the researchers measured their total energy expenditure. They found that participants in all groups maintained their weight, and there was minimal difference in secondary measures, including physical activity and resting energy expenditure (factors that could independently increase total energy expenditure).

This study raises the possibility that a focus on restricting carbohydrates, rather than calories, may work better for long-term weight control, said David Ludwig, professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health, who led the study with Cara Ebbeling from Boston Childrens Hospital.

Walter Willett, professor of epidemiology and nutrition at the Harvard Chan School, who was not involved in the study, noted that, These findings from a carefully conducted investigation can help explain why low-fat/high-carbohydrate diets are not successful for most people and have failed to maintain weight loss in formal randomized trials that have lasted for one year or longer.

This story originally appeared on the Harvard Chan Schools website, The Nutrition Source.

This work was conducted with grants from Nutrition Science Initiative (made possible by gifts from the Laura and John Arnold Foundation and Robert Lloyd Corkin Charitable Foundation), New Balance Foundation, Many Voices Foundation, and Blue Cross Blue Shield. David S. Ludwig was supported by a mid-career mentoring award from the National Institute of Diabetes and Digestive and Kidney Diseases (K24DK082730).
