Every part You Must Know

Angela Fitch’s household historical past of weight problems caught as much as her at age 40, when she was pregnant along with her first little one.

As a doctor and weight problems medication specialist, Dr. Fitch knew the life-style levers to tug—and he or she had the monetary means to yank them arduous.

After giving beginning, she lifted weights with a coach twice per week. She sweated via one Peloton exercise after one other and tracked her meals consumption on MyFitnessPal.

Nonetheless, for the following decade, Dr. Fitch misplaced (and regained) the identical 5 to 10 kilos. Her blood stress crept upward. Then got here a sleep apnea analysis.

As her fiftieth birthday neared, Dr. Fitch determined to take the recommendation she gave her sufferers. She went on medicine. (And, she misplaced 30 kilos.)

Within the years since, Dr. Fitch has sometimes stopped her meds. For a number of months, she maintains her outcomes.

Ultimately, nonetheless, the size climbs again. For now, she’s determined that she’ll be on medicine long-term.

If you happen to’re a coach, how does this story land with you?

Does it…

Make you’re feeling dissatisfied? Does this appear to be a narrative of somebody “giving up” or “not attempting arduous sufficient”?

Encourage you with a way of awe? That fashionable medication has found out find out how to deal with yet one more power illness?

Carry up questions? Like questioning concerning the results of being on medicine—probably long-term? (Or if weight reduction is even that related—as long as an individual is maintaining a healthy diet and exercising often?)

Dr. Fitch is now president of the Weight problems Medication Affiliation and chief medical officer of Recognized Effectively, a main care and weight problems medication observe in Needham, Massachusetts. No matter how you’re feeling about her story, it illustrates what can initially appear to be an inconvenient reality for these of us within the well being teaching business:

Conduct change by itself isn’t all the time sufficient.

For many individuals with weight problems, semaglutide (Ozempic, Wegovy, Rebelsus), tirzepatide (Mounjaro, Zepbound), and different glucagon-like peptide-1 receptor agonists (GLP-1 RAs) function priceless instruments that make vital and lasting weight reduction potential.

However for well being coaches, these medication can appear to be an existential risk.

You would possibly surprise:

‘Who wants a vitamin coach or a private coach when folks can get sooner, simpler, and extra dramatic outcomes with medication?’


Individuals want well being coaches now greater than ever.

On this story, we’ll clarify why—and present you find out how to flip “the golden age of weight problems medication” into an enormous profession alternative.

With fats loss, there’s no such factor as an “straightforward method out.”

To handle diabetes or deal with most cancers, most individuals think about it regular and pure to mix life-style behaviors with prescription medication.

Nobody would inform somebody with most cancers, “You’re on chemo? Method to take the straightforward method out!”

Nevertheless, that’s what many individuals with weight problems hear after they point out medicine or surgical procedure.

For many years, a lot of society hasn’t seen weight problems because the illness that it’s.

As an alternative, folks have seen it as a willpower drawback.

The treatment: “Simply attempt more durable.”

Nevertheless, fairly than motivating folks to succeed, this “treatment” usually encourages them to surrender. (Extra importantly, the willpower idea isn’t based mostly on science.)

In actuality, folks with weight problems possible have as a lot willpower as anybody else.

Nevertheless, for them, fats loss is more durable—due to genetics and physiology, together with social, cultural, behavioral, and/or environmental elements that work towards them.

Why is it so tough to lose fats?

Think about life 150 years in the past, earlier than the invention of the car. To get from level A to level B, you needed to stroll, pedal a bicycle, or trip a horse.

Meals was usually briefly provide, too. You needed to expend energy to get it, and meals would simply fulfill you (however not depart you feeling “full”).

At present, nonetheless…

“We dwell in an obesogenic surroundings that’s crammed with low-cost, highly-palatable, energy-dense meals [that make overeating calories easy, often unconsciously], and numerous conveniences that scale back our bodily exercise,”
says Karl Nadolsky, MD, an endocrinologist and weight reduction specialist at Holland Hospital and co-host of the Docs Who Elevate podcast.

You would possibly surprise: Why do some folks acquire fats in an obesity-promoting surroundings whereas others don’t?

The reply comes all the way down to, largely, genetics and physiology.

(Weight problems is complicated and multifactorial. As we famous above, there are different influential elements, however your genes and physiology are principally out of your management, and so medicine is likely to be the most effective device to switch their influence.)

Genetically, some persons are extra predisposed to weight problems.

Some genes can result in extreme weight problems at a really early age. Nevertheless, these are fairly uncommon.

Rather more widespread is polygenic weight problems—when two or extra genes work collectively to predispose you to weight acquire, particularly once you’re uncovered to the obesogenic surroundings talked about earlier.

Individuals who inherit a number of of those so-called weight problems genes are likely to have significantly persistent “I’m hungry” and “I’m not full but” alerts, says Dr. Nadolsky.

Weight problems genes additionally appear to trigger some folks to expertise what’s colloquially often known as “meals noise.”

They really feel obsessive about meals, regularly pondering, “What am I going to eat subsequent? When is my subsequent meal? Can I eat now?

Physiologically, our bodies have a tendency to withstand fats loss.

If you happen to acquire numerous fats, the hormones in your intestine, fats cells, and mind can change the way you expertise starvation and fullness.

“It’s like a thermostat in a home, however now it’s damaged,” says Dr. Nadolsky. “So when folks minimize energy and weight goes down, these physiologic elements work towards them.”

After reducing weight, your intestine could regularly ship out the “I’m hungry” sign, even in the event you’ve not too long ago eaten, and even in case you have greater than sufficient physique fats to function a calorie reserve. It additionally would possibly take extra meals so that you can really feel full than, say, another person who’s by no means been at the next weight.

Enter: GLP-1 medication

In 2017, semaglutide—an artificial analog of the metabolic hormone glucagon-like peptide 1—was permitted within the US as an antidiabetic and anti-obesity medicine.

With the emergence of this class of medication, science provided folks with weight problems a comparatively protected and accessible option to shed extra pounds long-term, as long as they continued the medicine.

How Ozempic and different weight problems medicines work

Present weight reduction drugs work primarily by mimicking the perform of glucagon-like peptide 1 (GLP-1), which is a hormone that performs a number of capabilities:

  • Within the pancreas, it triggers insulin secretion, which helps regulate blood sugar.
  • Within the intestine, it slows gastric emptying, affecting your sensation of fullness.
  • Within the mind, it reduces cravings (the need for particular meals) and meals noise (intrusive ideas about meals).

In folks with weight problems, the physique rapidly breaks down endogenous (pure) GLP-1, making it much less efficient. Consequently, it takes longer to really feel full, meals supply much less endurance, and meals noise turns into a near-constant companion, says Dr. Nadolsky.

Semaglutide (Ozempic, Wegovy, Rybelsus) and medicines prefer it flood the physique with synthetically made GLP-1 that lasts for much longer than the GLP-1 the physique produces. This long-lasting impact helps improve emotions of fullness, scale back between-meal starvation, and muffle cravings and meals noise.

Curiously, by calming down the mind’s reward heart, these medicines may additionally assist folks scale back addictive behaviors like drawback consuming and compulsive playing, says Dr. Nadolsky.

The lesser-known historical past of weight reduction medication

To know the facility of semaglutide (Ozempic, Wegovy, Rybelsus) and different GLP-1 medicines, it’s useful to know a bit concerning the medication that predated it.

A long time earlier than the age of Ozempic, physicians realized that a number of medication initially developed to deal with different circumstances additionally appeared to assist folks shed extra pounds.

These included:

  • Qsymia, which pairs phentermine (an older weight reduction medication) with the epilepsy medication topiramate
  • Contrave, which mixes the antidepressant bupropion (Wellbutrin) with naltrexone, used to deal with addictions
  • Metformin, a diabetes medication

Nevertheless, weight reduction from these older medicines was modest, serving to folks to lose (and hold off) round 5 to 10 % of their physique weight.1 2 3

Round 2010, liraglutide (Victoza, Saxenda) was permitted by the FDA to deal with diabetes. Like Ozempic and different newer weight reduction medicines, liraglutide mimics glucagon-like peptide-1 (GLP-1), however it’s much less efficient than the newer medicines.

Why does Ozempic get all of the credit score?

Ozempic has turn out to be the Kleenex of weight reduction medicines—a reputation model folks toss round as if it’s generic.

This fame is a minimum of partly earned: Dr. Fitch says that semaglutide (Ozempic, Rybelsus, Wegovy) additionally works extra successfully than liraglutide, its GLP-1 predecessor.

“Semaglutide is 94 % much like our personal GLP-1,” she says, “They’ve been capable of make it nearer and nearer to the GLP-1 our our bodies make.”

It additionally lasts longer than liraglutide, and extra of it reaches the mind.

Nevertheless, newer meds outperform Ozempic. (See the desk within the part under.)

And there are different medicines—accessible orally fairly than by way of injection—coming. These tablets will probably be simpler to mass produce, which can drive down prices and make GLP-1 medicines much more accessible to extra folks.

So, though Ozempic is the present reigning model of the burden loss drug world, it could be ousted in time.

The rising effectiveness of weight reduction medication (particularly together with life-style modifications)

Researchers measure a weight-loss medication’s success based mostly on the share of people that attain key weight reduction milestones.

For instance, most individuals begin to see well being advantages after dropping 5 % of their weight—and remission from illness after dropping round 20 %.

Because the chart under reveals, weight reduction medicines have turn out to be more and more efficient at serving to folks to succeed in each milestones.

Medication% of people that lose 5% of their weight% of people that lose >20% of their weight
First-generation weight reduction medicines (Qsymia, Contrave, Metformin) 4 5 653-80%10-20%
Semaglutide (Ozempic, Rybelsus, Wegovy) 7 886%32%
Tirzepatide (Mounjaro, Zepbound) 9 1085-91%50-57%
Retatrutide (not but FDA permitted) 11 1292-100%80-83%

How do weight reduction drugs examine to conventional interventions?

Prior to now, weight reduction interventions have targeted on life-style modifications like calorie or macronutrient manipulation, train, and generally counseling.

Fairly than pitting life-style adjustments towards weight reduction medicines or surgical procedure, it’s extra useful to think about all of them as instruments.

Because the graph under reveals, the extra weight reduction instruments somebody makes use of—together with teaching—the extra vital the outcomes.13 14 15 16

Bar graph compares five common weight loss tools: Lifestyle plus coaching; Lifestyle plus Semaglutide; Lifestyle plus Tirzepatide; Lifestyle plus Retatrutide; and Lifestyle plus Bariatric Surgery. Lifestyle plus coaching yeilds the lowest weight lost, with people losing, on average, five to 13 percent of their body weight. Lifestyle plus Bariatric Surgery yeilds the highest weight lost, with people losing, on average, over 30 percent of their body weight. Lifestyle plus medications tend to yeild losses between 15 and 25 percent of body weight.

Fats loss usually comes with highly effective well being advantages

For years, the medical group has advised people that dropping 5 to 10 % of their physique weight was ok.

Partly, this message was designed to right-set folks’s expectations, as few lose way more than that (and hold it off) with life-style adjustments alone.

As well as, this modest weight reduction additionally results in measurable well being enhancements. Lose 5 to 10 % of your complete weight, and also you’ll begin to see blood sugar, ldl cholesterol, and stress drop.17

Nevertheless, dropping 15 to twenty % of your weight, as folks are likely to do after they mix life-style adjustments with second-generation GLP-1s, and also you do way more than enhance your well being. You possibly can go into remission for a number of well being issues, together with:

  • Hypertension
  • Diabetes
  • Fatty liver illness
  • Sleep apnea

Which means, by taking a GLP-1 medication, you would possibly have the option finally to cease taking a number of different medication, says Dr. Nadolsky.

Specialists suspect GLP-1s could enhance well being even when no weight reduction happens.

“The medicines appear to supply additive advantages past simply weight discount,” says Dr. Nadolsky.

Analysis signifies that GLP-1s could scale back the danger of main cardiovascular occasions (coronary heart assaults and strokes) in folks with diabetes or coronary heart illness.18 19 20 In folks with diabetes, they appear to enhance kidney perform, too.21

The idea is that organs all through the physique have GLP-1 receptors on their cells. When the GLP-1s connect to those receptors within the kidneys and coronary heart, they appear to guard these organs from harm.

Because of this, in 2023, the American Coronary heart Affiliation listed GLP-1 receptor agonists as one of many 12 months’s high advances in heart problems.

Ozempic unintended effects

You’ve possible heard that slowed gastric emptying from GLP-1s can result in nausea, constipation, and different GI woes.

That’s all true.

Nevertheless, for many, these unintended effects are manageable, particularly with the assistance of some key methods (which we’ll cowl later).

For now, nonetheless, we’d prefer to hash out a selected draw back you’ve possible heard about from the media—as a result of it affords an enormous alternative for well being coaches.

When folks take GLP-1 weight reduction medicines, about 30 to 40 % of the burden they lose can come from lean mass.22 23 24

Put one other method: For each 10 kilos somebody loses, about six to seven come from fats and three to 4 from muscle, bone, and different non-fat tissues.

This statistic has been broadcast amongst many media shops in latest weeks as a dire warning towards taking Ozempic, Wegovy, or Zepbound.

Such tales usually fail to say two necessary caveats:

Caveat #1: Individuals with extreme weight problems usually have extra muscle and bone mass than others.

To know why, think about you have been pressured to put on a 100- or 200-pound physique swimsuit on daily basis for a 12 months. On a regular basis actions—getting out and in of chairs, strolling to and from the mailbox, climbing steps right into a constructing—would really feel like a resistance exercise.

That’s possible partly why bariatric surgical procedure sufferers expertise a nine-year extension on their life expectancy, regardless of 30 % of their weight reduction coming from lean mass. They’ve extra muscle than common to start with, and due to this fact can safely lose some.25 26

For folks with extreme weight problems, the well being increase from physique fats loss offsets the well being threat of muscle and bone loss, says Dr. Fitch.

That stated, there’s a caveat to the caveat: People who find themselves solely 30 kilos or so obese could not be beginning out with muscle and bone mass to spare. Particularly in the event that they’re older, they could start their weight reduction journey already under-muscled, with comparatively low bone density. In these folks, one other drop in lean mass and bone density can add as much as massive well being issues.


Caveat #2: Muscle and bone loss aren’t inevitable.

As Dr. Nadolsky places it, “Muscle loss isn’t a purpose to keep away from treating weight problems [with medication]. It’s a purpose to do extra train.”

That is the place coaches can shine.

By displaying purchasers find out how to undertake muscle-building behaviors like power coaching, mixed with ample protein consumption, you may assist folks offset the worst of the unintended effects when taking these medicines.

The yo-yo drawback

GLP-1s are costly, costing roughly $1000 USD a month. Consequently, many insurers both refuse to cowl them or restrict their protection to a 12 months or two.

As soon as the cash runs out, folks are likely to go off the meds—and the starvation and cravings return.

In the event that they’ve carried out little to alter their foundational consuming habits, this places them at a big drawback. In the event that they’re not consuming slowly and mindfully and enhancing satiety with veggies and lean protein, the return of starvation and meals noise might be overpowering.

That’s possible why, in a single research, individuals who stopped taking semaglutide regained, on common, two-thirds of the burden they’d misplaced.27

Line graph shows that people who take semaglutide will regain, on average, about two-thirds of the weight they lose within a year of discontinuing medication.

Once more, right here’s one other alternative for coaches…

Use weight reduction medication as a key that unlocks life-style adjustments.

Weight reduction medicines don’t render behavior-based methods out of date; they make them extra essential.

When GLP-1 medicines muffle meals noise and starvation, your shopper will discover it simpler to prioritize protein, fruits and veggies, legumes, and different minimally processed entire meals. Equally, as the size goes down, purchasers really feel higher, so that they’re extra prone to embrace weight lifting and do different types of train.

Based on a 2024 shopper developments survey, 41 % of GLP-1 medication customers reported that their train frequency elevated since occurring the medicine. Nearly all of them additionally reported an enchancment in food plan high quality, selecting to eat extra protein, in addition to vegatables and fruits.28

That is nice information, as a result of, as talked about above, life-style adjustments are essential to preserving lean mass and stopping regain, ought to purchasers select to discontinue medicine.

When working with purchasers on GLP-1s, hold the next challenges in thoughts.

Teaching technique #1: Discover methods to eat nutritiously regardless of unintended effects.

The slowed abdomen emptying attributable to GLP-1 medication can set off nausea and constipation.

Thankfully, for most individuals, these GI woes are likely to resolve inside a number of weeks.

Nevertheless, in the event you’re working with a shopper who’s experiencing numerous nausea, they received’t possible welcome salads into their lives with open arms. (Consider how you’re feeling when you may have the abdomen flu. A bowl of roughage doesn’t appear to be it’ll “go down straightforward.”)

As an alternative, assist purchasers discover extra palatable methods to eat nutritious meals. (For instance, vegatables and fruits within the type of a smoothie or pureed soup is likely to be simpler.)

Dr. Nadolsky additionally suggests folks keep away from the next widespread offenders:

  • Huge parts of any sort
  • Greasy, fatty meals
  • Extremely processed meals
  • Any robust meals smells that set off a shopper’s gag reflex
  • Sugar alcohols (like xylitol, erythritol, maltitol, and sorbitol, usually present in food plan sodas, chewing gum, and low-sugar protein bars), which may set off diarrhea in some

Teaching technique #2: Prioritize power coaching.

To protect muscle mass, purpose for a minimum of two full-body resistance coaching periods per week.

As well as, transfer round as a lot as you may. Strolling and different types of bodily exercise are important for retaining the burden off—and will help to maneuver meals via the intestine to ease digestion.29 30

(Want inspiration for power coaching? Take a look at our free train video library.)

Teaching technique #3: Lean into lean protein.

Along with power coaching, protein is significant for serving to to guard muscle mass.

You need to use our free macros calculator to find out the correct amount of protein for you or your shopper. (Spoiler: Most individuals will want 1 to 2 palm-sized protein parts per meal, or about 0.5 to 1 gram of protein per pound of body weight per day.)

Teaching technique #4: Fill your plate with fruit and veggies.

In addition to being good in your general well being, entire, recent, and frozen produce fuels you with essential vitamins that may assist drive down ranges of irritation.

Along with elevating your threat for illness, power irritation can block protein synthesis, making it more durable to keep up muscle mass.

(Didn’t know managing irritation issues in the case of preserving muscle? Discover out extra muscle-supporting methods right here: Easy methods to construct muscle power, dimension, and energy)

Teaching technique #5: Select high-fiber carbs over low-fiber carbs.

Beans, lentils, entire grains, and starchy tubers like potatoes and candy potatoes usually tend to assist purchasers really feel full and handle blood sugar than lower-fiber, extra extremely processed choices.

(Learn extra concerning the drawbacks—and occasional advantages—of processed meals right here: Minimally processed vs. extremely processed meals.)

Teaching technique #6: Select wholesome fat.

Wholesome fat will help you’re feeling full between meals and shield your general well being. Gravitate towards fat from entire meals like avocado, fatty fish (which can be a protein!), seeds, nuts, and olive oil—utilizing them to interchange much less wholesome fat from extremely processed meals.

(Undecided which fat are wholesome? Use our 3-step information for selecting the most effective meals in your physique.)

Teaching technique #7: Construct resilient habits.

It might go with out saying, however the above options are simply the beginning.

(There’s additionally: high quality sleep, social help, stress administration, and extra.)

Most significantly, purchasers want your assist to make all the above simpler and extra automated.

And that’s the actual present of teaching: You’re not merely serving to purchasers work out what to eat and find out how to transfer; You’re displaying them find out how to take away obstacles and create techniques and routines so their highway to well being is a bit smoother.

That method, in the event that they do must cease taking medicine, their ingrained life-style habits (that the medication made simpler for them to undertake) will make it extra possible that they preserve their outcomes.
