Weight Loss From Aerobic Exercise At Public Health Recommendation Levels
Clinical trials of ET that report no weight loss or modest weight loss still report numerous health benefits for overweight and obese adults with risk factors for disease. These benefits include improving CRF ,, glucose control ,, endothelial function ,, lipoprotein particle size , high density lipoprotiein , and quality of life ,. Weight loss as a result of aerobic ET is very heterogonous, and the overall response is related not only to total energy expenditure, but also compensatory changes in dietary caloric intake . Large randomized controlled trials which have evaluated the change in weight following aerobic ET programs consistent with PA recommendations have observed either no changes in weight or only modest weight loss.
Thus, overweight and obese adults who adhere to an exercise program consistent with public health recommendations without a dietary plan involving caloric restriction can expect to experience weight loss in a range of no weight loss to approximately 2 kgs. Clinicians should caution their patients that the chances of substantial weight loss are unlikely at these ET levels without caloric restriction . Regardless of the amount of weight loss, clinicians should emphasize that numerous health benefits occur in the absence of weight loss, and that maintenance of an active lifestyle will reduce the risk of future weight gain ,. An important limitation of the present data in this area is that long-term and time-course studies are not currently available.
Excess Calorie Intake Explains Weight Gain
The fact that the adults were five pounds shy of the 24-pound predicted weight gain means that excess food intake still explains the weight gain, but that there may have been increases in physical activity over the 30 years that have blunted what would otherwise have been a higher weight gain, Dr. Swinburn stated.
To slim back down to our average weight of the 1970s, a time when America was not struggling with an obesity epidemic, we would need to reverse the increased food intake of about 350 calories a day for children and 500 calories a day for adults , stated Dr. Swinburn.
Diet Vs Exercise: Dieting The Right Way
As mentioned earlier, weight loss programs such as the Atkins diet the keto diet have gained popularity in recent years.
However, is this the right approach? Should we be cutting out certain foods and loading up on others in order to maximize weight loss?
McGregor says that, for most people, the answer is no. When you are attempting to lose weight, the best approach is to reduce your overall intake of all food groups rather than remove a complete one,” she advises.
“Many believe that diets like Atkins, Paleo and Keto are successful because of the removal of carbs, but studies show that its the overall decrease in energy that results in weight loss and that this is much more sustainable when no food groups are removed.
The dieting approach McGregor describes is known as ‘calorie deficit’. In simple terms, this involves consuming fewer calories than you burn every day.
It’s based on the fact that the body needs a minimum amount of energy every day to perform its basic functions – this is know as Resting Metabolic Rate . Physical activity performed on top of this increases calorie burn further.
A typical calorie deficit would be between 10-15% under your RMR, which differs from person to person based on factors such as sex, weight and age. You can find out more on how to calculate your RMR and how to follow a calorie deficit diet in our article ‘how many calories should I eat a day?‘

Why Is Your Food So Much More Important Than Your Exercise
Right now Im working with a group of women who are aiming to safely lose 10lbs in 4 weeks. Ask them what this program focuses on and I dont think youll get any hesitation: Its all about cleaning out poor food choices , and replacing them with the most nutritious foods we can find.
What about the exercise? Sure, some types of exercise are more effective than others, but for the most part I dont really care what my clients choose for their regular physical activity. As long as they are making the right food choices , then I know theyll get the results theyre looking for.
How can I be so confident? Watch this video that shows the dramatic impact of your food choices:
Is There Any Evidence To This
I explained why its assumed that diet beats exercise where weight loss is concerned. But all of that is still just theory. What about real-life examples?
Well, one systematic review of studies with at least 1-year follow-up found that people using exercise alone experienced minimal to no weight loss compared to those put on diets or a combination of diet and exercise .
A review article published in DiabetesSpectrum suggested that the subjects in those studies likely didnt exercise hard enough . The same article proved its point with studies where folks successfully lost weight with exercise alone, and these studies involved vigorous activity well beyond the minimum national recommendations of 150 min of exercise a week. Specifically, they sweat it out for around 7 hours per week.
So, there you have it. You definitely can lose weight with exercise. However, you can do so only if you create a substantial calorie deficit, which is possible only with vigorous and long physical activity. Thats something most people at the beginning of their weight-loss journey will likely find challenging.

Ozempic/wegovy: Side Effects And Weight Loss
The side effects appear much less than one would think. Only 5% of patients withdrew from studies. Most occur early and during the first few days after the injection, especially when escalating the dose. The most common side effects reported in 5% of patients treated are:
Stomach side effects are most common when starting treatment but decrease over time in most patients.
Zofran 4 mg or 8 mg is a inexpensive treatment for nausea. It is a little tablet placed under your tongue. Its used for chemotherapy nausea.
Despite being a drug for diabetes, low blood sugars are not seen from the drug.
Significant weight loss is seen at doses less than 2.4 mg/week as would be encountered with Ozempic at standard doses, i.e. up to 1 mg/week.
Weight Loss with Semaglutide: Ozempic and Wegovy Very variable, some weight loss with the 0.5 mg, much more at 1.0 mg and still increasing with dose titration. See a graph showing weekly % weight loss on standard protocol. Note these are % of weight loss, not the actual weight loss. The first 8 weeks were the o.25/0.5 mg dose. Notice the weight loss at 10-12 weeks accounted for about 2/3 of total weight loss.

Characteristics Of Included Studies
Eight studies were included, four of which included both diet-only and physical activity-only arms and, therefore, contributed to both meta-analyses. Three studies included only a comparison of diet only interventions with combined BWMPs and one study only a comparison of a physical activity only intervention with combined BWMP.
The eight included studies represented 1,022 participants. The number of participants in each study ranged from 59 to 352, with a mean of 128 participants per study. One study was conducted in Sweden, one in Belgium, and six in the United States. The mean age of study participants ranged from 32 to 70 years and, as is common in weight loss studies, the majority of participants were women . The mean BMI ranged from 29.2 to 37.3. Seven studies reported weight change at 12 months from baseline and one at 18 months.
Comparing 1970s With Today
They also calculated how many calories Americans were actually eating in the 1970s and in the early 2000s, using national food supply data. As you no doubt guessed, were chowing down more in the 21st century. Compared to the 70s, adults in the early 2000s ate about 500 more calories a day. Children took in about 350 calories more daily.
The scientists then used their findings to predict how much weight they would expect American kids and adults to have gained from the 1970s to the early 2000s if calorie intake were the only influence.

Apply The : 20 Rule For Results
Have you read success stories of dramatic weight loss? At the forefront of the accomplishments of the people in these success stories are improved nutritional programs and diets. Some have shared the application of drastic food changes and also healthier methods of cooking and eating before starting an exercise program.
This began the journey of their success, and adding in the workouts was the bonus that made it all come together. It was important to master a healthy nutrition plan. These successful people also understood mastering a healthy nutrition plan as the largest role in being able to reach fitness goals.
It may be nice to think positive body changes can be made simply by exercising, but that’s far from the truth. Applying the 80:20 rule creates the difference and understanding food will be the major player in how you look. Finally, this is an easy foundation to approach body composition, but it is more complicated because stress, sleep, and genetics also plays a role. To really understand how all of these components affect the body, it is recommended to see a registered dietitian nutritionist.
Apply A Nutritional Strategy
A person can change one’s body composition through diet alone without exercise. However it’s the combination of both that provides a complete healthy package. Applying the 80% nutrition-to-20% fitness rule is simply a statement of the importance of nutrition in the equation. This distribution isn’t scientifically proven. It is based on the fact that it is easier to consume calories versus burning calories.
We have all seen the regulars at the gym doing the same thing day in and day out for several months or even years without seeing results in fat loss. These people are not making any headway in changing their body composition because they do not have a nutritional strategy. The lack of a nutritional strategy is holding these people back from reaching their fitness goals.
Exercise without healthy eating is not a waste of time, but it is like swimming upstream.

For starters, both fitness and food choices are vital for long-term weight control. The National Weight Control Registry, established in 1994 by scientists at the University of Colorado and Brown Medical School, is following more than 10,000 Americans who have lost weight and kept it off for years. Just 1% kept the pounds off with exercise alone, 10% did it with diet alone, and 89% used both.

Running On Empty: Fat Is A Feminine Issue
The good news The latest scientific findings from the US suggest that an intense workout in the gym is actually less effective than gentle exercise in terms of weight loss. Barry Braun, associate professor of kinesiology at the University of Massachusetts, says that the evidence emerging from his research team shows that moderate exercise such as “low-intensity ambulation” may help to burn calories “without triggering a caloric compensation effect” ie without making you reach for a snack the moment you’re done. In one experiment, Braun showed that simply standing up instead of sitting used up hundreds more calories a day without increasing appetite hormones in your blood.
The bad news Perhaps offering one reason for a multi-billion-pound weight-loss industry aimed almost exclusively at women, research has confirmed that it is more difficult for women to shed the pounds than men, because women’s bodies are simply more efficient at storing fat. In one of Braun’s experiments, in which overweight men and women were monitored while walking on treadmills, the women’s blood levels of insulin decreased while appetite hormones increased the men’s, meanwhile, displayed no such change. “Across the evidence base, it seems that it’s tougher for women to lose weight than men,” affirms Ken Fox, professor of exercise and health sciences at Bristol University.
Ozempic Vs Wegovy For Weight Loss
Ozempic and Wegovy, the newest weight loss drugs, are in the family of Glucagon-like peptide 1 receptor agonists. GLP-1s are medications that were first developed for the treatment of diabetes. When treating diabetics these group of medications not only caused reductions in blood sugar but significant weight loss. This led to the discovery of several GLP-1 medications including most recently liraglutide and semaglutide that possessed significantly greater weight loss effects that most anti-obesity medications. The first of these GLP-1s to be evaluated for its weight loss properties was liraglutide. Once daily injections of liraglutide resulted in 37% of patients experiencing a 20% weight loss or more from starting weight vs. 7% for placebo. This is far above the average FDA requirement of 5% or more weight loss from baseline. Numerous studies have been done to find the mechanisms for the weight loss that often equals the weight reduction observed after bariatric surgery. These mechanisms include:
The drawback of daily injections of liraglutide led to the search for other GLP-1s that could be administered by once a week injection and even taken orally. This led to the discovery of Ozempic for diabetes and the same drug, re-labelled Wegovy for weight loss.

Diet Vs Exercise: The Truth About Weight Loss
I admit it: I was once one of those women for whom post-pregnancy weight loss was relatively quick and painless. Ive never been model-skinny, but after the birth of my first two children my previous waistline was recovered with little to no effort. Yeah, I know what you want to call me, and I dont blame you. So kick back and laugh when I tell you that the pounds decided they wanted to take up permanent residence after my third son was born. No amount of calorie counting or exercise did the trick, which threw me for a tailspin worse than those teacups at Disney World.
One morning, by way of The Dr. Oz Show, I discovered Shaun T, fitness trainer and creator of INSANITY workout . His program intrigued me, but what really kept my attention was the way he harped on nutrition. Most exercise programs promise extreme results just by going through the motions. But he was adamant that great results can only be achieved by also overhauling your eating habits. Since exercising like a maniac had scarcely made a dent in my dimples, I decided to give his way a shot. Sayonara, fried and processed food. I was in for a nutritional overhaul.
Rumor: Nutrition and exercise are equally important when trying to lose weight
Diet and exercise. Depending who you talk to, these words are either dirty or sacred. Theres no doubt that theyre both vitally important to good health, but do they carry equal weight when it comes to losing weight?
