Some studies have suggested that one particular type of activity may be best for weight loss.

The best type of exercise for weight loss is the one that suits the individual, research suggests.

The study compared endurance exercise, strength training, a combination, or just trying to meet the weekly target for physical activity in whatever way works.

All three approaches produced a similar amount of weight loss, when combined with a low-calorie diet.

The results come from a study of 96 obese people who took part in a 22-week program.

Everyone in the study reduced their calorie intake while trying different types of exercise.

Some did endurance exercise like cycling, running or using a elliptical machine.

Some did strength training, such as bench presses, bicep curls and squats.

Still others did a combination of the two.

A comparison group were just told to stay active and meet the minimum activity guidelines.

These involve doing 30-60 minutes of moderate activity on most days of the week.

Things like taking the stairs and walking briskly would count.

The results showed that all the types of exercise and diet combinations reduced body weight, waistline, fat and increased lean muscle mass.

The authors write:

“The present study shows that, when adhered to alongside a hypocaloric diet, different exercise training programs (endurance, strength, or their combination) or the following of physical activity recommendations are equally efficient in terms of improving body weight and body composition variables in obesity management.”

One calorie burned in exercise is not the same as one not ingested.”

Other studies have suggested that one particular type of activity may be best for weight loss.

For example, one study found that jogging is the best exercise for those with a genetic susceptibility to weight gain.

A range of studies have found that high-intensity interval training (HIIT) is one of the best exercises for weight loss.

However, HIIT can be difficult for people to stick to.

In the end, the current study’s suggestion that it comes down to the individual is the best advice.

The study was published in the Journal of Applied Physiology (Benito et al., 2015).

Does the best way to lose weight involve intermittent fasting or reduced calories across all meals everyday?

Intermittent fasting is sometimes promoted as a magic bullet to lose weight.

However, a new study found that this method is not as effective as traditional daily calorie restriction plans.

Intermittent fasting is an umbrella term for dietary restriction plans that follows different meal timing schedules for a period of time.

The “5:2” diet, alternate-day fasting and time-restricted feeding are examples.

In the past few years, fasting diets have become more popular with images of celebrities showing miraculous weight loss.

Yet, the benefits of intermittent fasting are not as strong as traditional daily calorie restriction.

The current research shows that people who followed a traditional diet lost more weight than those who were fasting, despite both eating the same number of calories.

For this study, participants were divided into three groups:

• Non-fasting dieting group: received 25 percent less calories across all meals every day.
• Fasting group: alternating 24-hour periods of complete fasting and eating 50 percent more than usual on non-fasting day.
• Fasting on alternate days: fasting one day then consuming 100 percent more than usual daily intake.

Prior to the study, all the participants had a typical diet of 2000-2500 calories every day.

During the study period, the average daily energy intake was reduced to 1500-2000 calories for the first and second groups.

The non-fasting group lost 1.9 kg in three weeks and body scans confirmed this amount of weight loss was completely from burring body fat and belly fat.

The second group lost 1.6 kg in three weeks but half this weight loss was from burning body fat and the other half was from losing muscle mass.

The third group, however, didn’t lose any weight.

Professor James Betts, the study’s lead author, said:

“Many people believe that diets based on fasting are especially effective for weight loss or that these diets have particular metabolic health benefits even if you don’t lose weight.

But intermittent fasting is no magic bullet and the findings of our experiment suggest that there is nothing special about fasting when compared with more traditional, standard diets people might follow.

Most significantly, if you are following a fasting diet it is worth thinking about whether prolonged fasting periods is actually making it harder to maintain muscle mass and physical activity levels, which are known to be very important factors for long-term health.”

The study was published in the journal Science Translational Medicine (Templeman et al., 2021).

An effective drug treatment for weight loss if you can tolerate the side-effects.

A combination of phentermine and topiramate extended release treatment could help overweight or obese adults to lose at least 5 percent of their weight.

The extended-release phentermine plus topiramate is an FDA approved drug for treating obesity.

Past studies have been shown that 7.5 mg phentermine and 46 mg topiramate daily dosage over one year led to a minimum of 5 percent weight loss.

A study found that when the phentermine and topiramate dosage increased, the weight loss was 10 percent or greater in obese and overweight patients.

Topiramate is an approved anti-convulsant drug which is used for treating seizures and preventing migraine.

Phentermine is an appetite suppressant medication used for treating obesity in conjunction with diet and exercise.

A 12-week trial by Guerdjikova et al., 2018, suggests that the combination of phentermine and topiramate extended-release (brand name Qsymia) together with a low-calorie diet and higher physical activity would effectively lower weight and body mass index (BMI).

They found that the combined phentermine–topiramate medication reduces binge-eating symptoms in patients with binge-eating disorder.

Dr Caroline Kramer and colleagues found that a 28-week daily dosage of 96 to 200 milligrams topiramate on its own resulted in 10 percent or greater weight loss.

The review investigated 10 trials on 3,300 overweight or obese patients who took topiramate over four months and lost 11.8 pounds (5.4 kg) compared with those who took “dummy” pills known as placebo.

Dr Kramer, the study’s lead author, said:

“Topiramate is not an approved drug for the treatment of obesity.

Data from individual clinical trials might not be sufficient to support physicians’ decision to prescribe it for this use, and robust evidence of its safety is lacking.”

The weight loss benefits appear to increase the higher the dosage and the longer the treatment.

However, higher doses of phentermine medication alone or with topiramate would make patients experience serious side-effects such as depression, anxiety and insomnia.

Dr Kramer said:

“Topiramate has a substantial effect on weight loss, at least comparable to the weight loss that other anti-obesity drugs induce.

We have so few pharmacological options for the treatment of obesity that I believe topiramate can be a useful tool together with diet and exercise.”

However, she emphasised that patients need to be aware of the possible side-effects.

The adverse effects include paraesthesia, a burning sensation of the skin, cognitive impairment like slower thinking, low concentration, memory loss, and movement disorders.

The studies were published in the journal Obesity Reviews (Kramer et al., 2011) and The Lancet Journal (Gadde et al., 2011). 

This major barrier to weight loss is easy to change.

A major barrier to weight loss is that dieters plan to eat foods they do not enjoy, like brussels sprouts.

Not only that, but they typically cut out all the foods they do enjoy, such as strawberries.

Naturally, this is a recipe for dieting failure because a lack of pleasure reduces motivation.

Instead, dieters should choose tasty and healthy foods that they enjoy eating.

An unhealthy treat from time-to-time probably does little harm.

The conclusions come from a study including 542 people whose dieting strategies were tested.

Dr Meredith David, the study’s first author, said:

“Our research shows that instead of creating rules to avoid one’s favorite treats, dieters should focus on eating healthy foods that they enjoy.

Dieters who restrict themselves from consuming the foods they love most may be setting themselves up for failure.

Instead, they may be better off by allowing occasional ‘treats’ and focusing attention on healthy foods that they enjoy and making it a point to include those tasty, but healthy foods in their diet.”

Dieting is particularly hard for people with low self-control.

Unfortunately, this type of people tend to restrict themselves from eating their favourite foods, when it might be better to allow an occasional treat.

People with low self-control are also more likely to choose healthy foods that they do not like eating, the study found.

Dr David said:

“In coming up with plans to enhance one’s health and well-being, low self-control individuals tend to set themselves up for a harder pathway to success by focusing on avoiding the very foods they find most tempting.

Our data reveals that individuals who are generally more successful at reaching their goals tend to develop more motivating plans regarding the inclusion of healthy, well-liked items and the exclusion of unhealthy items that are not one’s favorites.”

Dr David said pleasure is important:

“Frequent attention is given to health advice surrounding well-intentioned lists of ‘magical’ foods that everyone should eat or practically ‘poisonous’ foods that people should avoid consuming.

The next time you decide to go on a diet or seek to improve your health by altering your food consumption, opt for strategies that focus on including healthy foods in your diet, and focus specifically on those healthy foods that you really enjoy eating.”

The study was published in the journal Psychology & Marketing (David & Haws, 2016).

The diet means you can eat whatever you like…

A simple fasting technique called the 16:8 diet is an effective way to lose weight, research finds.

It involves eating whatever you like between the hours of 10am and 6pm.

Outside these hours, only water and other calorie-free drinks are allowed.

The name comes from the fact that it involves fasting for 16 hours (from 6pm to 10am the next morning) and feasting for 8 hours.

The advantage of this diet is that it is extremely simple to follow, says Dr Krista Varady, study co-author:

“The take-home message from this study is that there are options for weight loss that do not include calorie counting or eliminating certain foods.”

The study involved 23 obese people who followed the diet for 12 weeks.

On average, they lost around 3% of their body weight and their blood pressure also reduced significantly (compared with a control group).

The results are similar to those seen in other studies of intermittent fasting, Dr Varady said:

“The results we saw in this study are similar to the results we’ve seen in other studies on alternate day fasting, another type of diet, but one of the benefits of the 16:8 diet may be that it is easier for people to maintain.

We observed that fewer participants dropped out of this study when compared to studies on other fasting diets.”

The study’s authors write:

“These preliminary data offer promise for the use of time-restricted feeding as a weight loss technique in obese adults, but longer-term, large-scale randomized controlled trials [are required].

The 16:8 diet is another tool for weight loss that we now have preliminary scientific evidence to support.

When it comes to weight loss, people need to find what works for them because even small amounts of success can lead to improvements in metabolic health.”

The study was published in the journal Nutrition and Healthy Aging (Gabel et al., 2018).

These two treatment strategies might be the secret to maintaining weight loss.

Losing weight can be easier than avoiding regaining it.

However, Danish scientists have found a combined therapy to maintain weight loss, once it has been achieved.

In the study, obese participants, after an 8-week low-calorie diet, lost more than 13 kg.

After this initial weight loss, those who received an exercise program combined with obesity medication, saw twice the decrease of body fat than the other groups.

Nearly half of the world’s population is overweight and 1-in-6 are obese.

They face serious health consequences such as infertility, heart disease, diabetes, cancer, and premature death.

There are many successful plans for losing weight, but the problem is that most people will regain weight over time.

The Danish study reveals the possible ways to sustain weight loss over a long period of time.

The research team enrolled 215 Danes with obesity and poor fitness to take a low-calorie diet weight loss program for 8 weeks.

The subjects lost 13.1 kg plus a significant reduction in blood pressure and blood sugar levels during this period.

Then they were divided into four groups:

• One group received an appetite-inhibiting obesity medication (3.0 mg per day of liraglutide) only.
• A combination group received the obesity medication plus an exercise program.
• The other two groups received a placebo medication instead of liraglutide, however, one of these two group also did an exercise program.

The exercise program consisted of 75-minutes vigorous intensity activity or a 150-minutes moderate-intensity activity per week.

Nutritional and diet counselling were regularly provided for all the groups to maintain their healthy weight loss.

Professor Signe Sørensen Torekov, the study’s senior author, said:

“This is new knowledge for doctors, dietitians and physical therapists to use in practice.

This is evidence that we have been missing.

The problem is that people are fighting against strong biological forces when losing weight.

The appetite increases simultaneously with decreased energy consumption, and this counteracts weight loss maintenance.

We have an appetite-stimulating hormone, which increases dramatically when we lose weight, and simultaneously the level of appetite-suppressing hormones drops dramatically.

In addition, a weight loss can provoke loss of muscle mass, while the body reduces the energy consumption.

Thus, when the focus in obesity treatment has been on how to obtain a weight loss — rather than how to maintain a weight loss — it is really difficult to do something about your situation,”

The liraglutide (obesity medication) group and the exercise group still kept the 13 kg weight off while the placebo group put half of the weight back after one year.

The combination of liraglutide with the exercise showed amazing results as participants in this group lost 16 kg, twice as much body fat, increased muscle mass, lowered blood pressure, decreased blood sugar, and had better fitness levels than the other groups.

Professor Torekov said:

“It is an important aspect to highlight, as you do not necessarily get a healthier body from losing weight if, at the same time, you lose a lot of muscle mass.

It is great news for public health that a significant weight loss can be maintained with exercise for approximately 115 minute per week performed mostly at vigorous-intensity, such as cycling.

And that by combining exercise with obesity medication, the effect is twice as good as each of the individual treatments.”

The study was published in the New England Journal of Medicine (Lundgren et al., 2021).

People experience more success with personal goals like weight loss with this technique.

People lose more weight when they share their progress with others online, research finds.

The study shows the benefit of sharing both successes and failures with friends and followers on social media.

People who shared their progress online demonstrated more commitment to changing their eating habits, the study found.

Dr Tonya Williams Bradford, the study’s first author, said:

“Our research finds that individuals are more likely to realize success with personal goals when they make a public commitment to attaining them.

By sharing success and setbacks in virtual support communities on social media, we found people are achieving better results.

This works especially well with goals like weight loss, where before and after images can be shared online with other community members.”

The study followed a group of people who were trying to lose weight over four years.

The results showed that making a public commitment to weight loss made people more likely to follow through.

Dr Bradford explained:

“Through our research we found public commitment, which is a declaration of a position, increases the likelihood of compliance to a course of action and is a key part of a successful weight loss plan.

When people seeking to lose weight join a virtual support community and share their plans online to attain their goals, they invite members to join them by offering encouragement in both words and actions.

This exchange of online support facilitates adherence to the offline goal of losing weight.

Public accountability is key.”

The study was published in the journal Journal of Interactive Marketing (Bradford et al., 2017).

Most people overlook the main barrier to weight loss.

Ninety per cent of people do not realise that emotional eating is a key barrier to weight loss, a survey finds.

Most people think diet and exercise are the biggest barriers to weight loss and reckon without the influence of the mind.

Dr Diane Robinson, a neuropsychologist at Orlando Health, said:

“Most people focus almost entirely on the physical aspects of weight loss, like diet and exercise.

But there is an emotional component to food that the vast majority of people simply overlook and it can quickly sabotage their efforts.”

The survey of over one thousand people found that 31% said that lack of exercise was the biggest barrier to weight loss, while 26% said it is what you eat.

Only 10% agreed that psychological well-being was a key barrier to weight loss.

Dr Robinson said:

“That may explain why so many of us struggle.

In order to lose weight and keep it off long term, we need to do more than just think about what we eat, we also need to understand why we’re eating.

Most people have a very emotional attachment to food.

Food is given to children to make them feel better, it is the central component of celebrations and it creates powerful emotional connections.

Dr Robinson said:

“If we’re aware of it or not, we are conditioned to use food not only for nourishment, but for comfort.

That’s not a bad thing, necessarily, as long as we acknowledge it and deal with it appropriately.”

Eating a satisfying meal releases a ‘feel-good’ neurotransmitter called dopamine, said Dr Robinson:

“We feel good whenever that process is activated, but when we start to put food into that equation and it becomes our reward, it can have negative consequences.”

Dr Robinson recommends keeping a food diary to help look for unhealthy eating patterns.

Ensure that food is not being used as a coping mechanism or a reward — but purely for nourishment.

The  survey was commissioned by Orlando Health.

People in the study had lost an average of 77 pounds and were trying to maintain their weight loss.

One of the biggest barriers to weight loss is being criticised by others, new research finds.

People trying to lose weight are sometimes sabotaged by others making unkind or sarcastic remarks, such as “You are going to gain it all back!”

Attacks from others may be motivated by jealousy and feelings of  negativity about their own lifestyle.

Afraid of being judged themselves, cruel people lash out at others first.

The conclusions come from a study of 40 people who had lost an average of 77 pounds (35 kg) and were trying to maintain their weight loss.

Researchers interviewed them about their experiences.

Dr Lynsey Romo, the study’s author, said:

“Many times, when someone loses weight, that person’s efforts are undermined by friends, family or coworkers.

This study found that people experience a ‘lean stigma’ after losing weight, such as receiving snide remarks about healthy eating habits or having people tell them that they’re going to gain all of the weight back.”

People who had lost weight said they used all sorts of techniques to try and deal with other people’s comments, Dr Romo explained:

“All 40 of the study participants reported having people in their lives try to belittle or undermine their weight loss efforts.

However, the study found participants used specific communication strategies to cope with lean stigma and maintain both their weight loss and their personal relationships.”

Techniques used included telling people they had lost weight for ‘health reasons’ and to ‘have more energy’.

They also tried to keep their healthy eating subtle.

Dr Romo said:

“Study participants would go out of their way to make clear that they were not judging other people’s choices.

For example, participants would stress that they had changed their eating habits for health reasons, or in order to have more energy.”

The study was published in the journal Health Communication (Romo, 2018).
