What Is Medical Weight Loss?
A medical approach beyond traditional dieting.
Medical weight loss is a provider-guided approach to weight management that considers the medical, metabolic and lifestyle factors that may influence body weight.
Unlike a standard diet program, it begins with an evaluation of your health history, medications, previous efforts, symptoms and goals, with lab or hormone testing when appropriate. A personalized plan may include prescription medication, nutrition guidance, lifestyle support and monitoring, with the goal of sustainable change, not just short-term loss.
How Weight Loss Works
Treatment that evolves with your progress.
It begins with a consultation about your health history, weight challenges, medications, lifestyle and goals. Based on that evaluation, your provider develops a personalized plan that may include GLP-1 therapy or other prescription medications, nutrition and lifestyle recommendations, and supportive treatments when appropriate.
Regular follow-up is an important part of the process. Your provider monitors progress, symptoms, medication tolerance and treatment response and adjusts the plan when needed. Over time, the focus shifts toward maintaining results, supporting healthy habits and a sustainable long-term strategy.
Why Weight Loss Can Be Difficult
Understanding the Factors That May Be Affecting Your Progress
Many patients seeking medical weight loss have already tried changing their diet, exercising more, or following commercial weight-loss programs without achieving the results they expected. That does not necessarily mean they lack motivation.
Factors including appetite regulation, insulin resistance, medications, sleep, stress, hormonal changes, metabolic health, muscle mass, age, and lifestyle may influence how easily someone loses or maintains weight. Our approach considers these factors together instead of focusing only on calories or the number on the scale.
A medical evaluation can help identify concerns that may need to be addressed while also determining whether prescription medication, lifestyle changes, nutritional support, or other treatment options may be appropriate. The goal is to create a plan that fits the individual rather than asking the individual to fit a predetermined program.

What Your Medical Weight Loss Program May Include
Treatment Options Selected Around Your Individual Needs
Full Evaluation
A 90-minute visit covers your history, medications, past efforts and goals, with labs drawn to check your metabolic and hormone health.
Prescription Options
For eligible patients, GLP-1-based or other prescription treatment may be part of the plan, chosen around your health history, medications and risks.
Lifestyle Support
Medication does not replace healthy habits, so nutrition, movement, sleep, stress and daily routines all remain part of a sustainable plan.
Ongoing Monitoring
Follow-up visits track your progress, side effects and labs, so your plan can be adjusted and shift from treatment to long-term maintenance.
Your First Visit
Monitored at Every Visit
At each follow-up, Allana checks vital signs such as heart rate and temperature and reviews how you are responding to your weight loss plan.

GLP-1 Therapy for Medical Weight Loss
Prescription Treatment Combined With Comprehensive Weight Management
GLP-1 medications, often called weight loss injections, have become an important option for some adults seeking medically supervised weight management. They can influence appetite regulation and feelings of fullness, which may help eligible patients follow a reduced-calorie eating plan more consistently, and they work best alongside healthy eating and physical activity.
After an individual evaluation, treatment may include semaglutide or tirzepatide when clinically appropriate. Semaglutide is a GLP-1 receptor agonist, while tirzepatide acts on both GIP and GLP-1 pathways. FDA-approved versions of both active ingredients are available for chronic weight management in eligible patients.
Benefits of Medical Weight Loss
Treatment Options Selected Around Your Individual Needs
Individualized Medical Care
Your plan is built around your health history, metabolic markers, medications, and goals, so recommendations fit your situation instead of a generic diet or one-size-fits-all weight loss program.
Metabolic & Hormone Insight
Evaluation looks at metabolic and hormone-related factors that can affect appetite, energy, and weight, helping explain why past efforts may have stalled and what may help you move forward now.
Sustainable Lifestyle Habits
Practical nutrition, activity, and lifestyle guidance supports changes you can maintain, so progress is built on habits that fit your routine rather than short-term restriction or extreme diets that are hard to keep up.
Long-Term Weight Management
Ongoing follow-up helps you maintain results over time, with your plan adjusted as your weight, health markers, and goals change, including planning for life after weight loss medication.
Medication Is One Part of the Plan
Building a Weight Management Strategy Beyond the Prescription
Prescription medication can be a useful tool, but medical weight loss is more than medication alone. Nutrition, movement, sleep, stress, muscle maintenance and long-term habits all influence your results.
Throughout the program, you learn what to expect, potential side effects, and how progress is evaluated. As your weight changes, treatment may change too: some patients continue medication longer term, while others transition to a different approach based on treatment response, tolerance and long-term goals.
Patients who want one provider for both weight management and everyday health concerns may also consider our Direct Primary Care membership, which is separate from weight loss treatment.
Body Composition & Emsculpt NEO
Supporting Muscle and Body Composition During or After Weight Loss
Weight loss and body composition are related, but they are not the same thing. For appropriate patients, Emsculpt NEO may complement a broader medical weight-management program by targeting muscle and localized fat in specific treatment areas.
Emsculpt NEO is not a weight-loss or obesity treatment, and it does not replace medical weight loss. Instead, it may be considered for patients who want to improve muscle tone, strength, definition, or body contour during or after their weight-loss journey.
Whether Emsculpt NEO belongs in your plan depends on your goals, treatment area, health history, and overall medical weight-management strategy.

Who Treatment May Fit, Safety and Important Information
Who May Be a Candidate for Medical Weight Loss?
Medical Weight Management for Adults Who Need More Than a Diet Plan
Medical weight loss may be appropriate for adults who have struggled to lose or maintain weight through lifestyle changes alone, have overweight or obesity, experience weight-related health concerns, or want a medically guided approach to improving metabolic health.
Patients should be willing to participate in ongoing follow-up and understand that prescription treatment works best as part of a broader plan that includes healthy eating, physical activity, and sustainable lifestyle habits.
A consultation is necessary to determine whether treatment is appropriate.
Who May Not Be a Candidate for Medical Weight Loss?
Treatment Eligibility Depends on Your Individual Health
Not every treatment is appropriate for every patient.
Certain weight-management medications may not be appropriate during pregnancy or breastfeeding or for people with specific medical conditions, medication interactions, contraindications, or other risk factors.
Patients seeking rapid weight loss for cosmetic reasons alone may also require a different approach.
Your provider will review your medical history, medications, current health, and treatment goals before determining whether prescription weight-management treatment is appropriate for you.
Clinical Oversight & Safety
Medical Weight Loss Requires Appropriate Evaluation and Follow-Up
All medical weight-loss treatment at Lake Forest Regenesis is provided with clinical evaluation and ongoing medical oversight.
Before prescription treatment is recommended, your provider reviews relevant health history, medications, symptoms, potential contraindications, and individual risk factors.
Follow-up may include weight and symptom review, medication tolerance, side-effect monitoring, laboratory testing when appropriate, and treatment adjustments.
Prescription medications are used only when clinically appropriate, and treatment may be modified or discontinued depending on individual response and medical needs.
Results vary between patients, and no specific amount or rate of weight loss can be guaranteed.
When We Refer to a Specialist
If your evaluation points to something beyond Allana's scope, such as a suspected hormonal or endocrine disorder, a possible eating disorder, or a situation where bariatric surgery may be worth considering, she refers you to the right specialist and helps coordinate next steps.

Frequently Asked Questions
Clear Answers About Medical Weight Loss at Lake Forest Regenesis
Is medical weight loss the same as GLP-1 therapy?
No. GLP-1 therapy may be one component of medical weight loss, but a comprehensive program can also include medical evaluation, laboratory testing when appropriate, nutritional and lifestyle guidance, ongoing monitoring, and other individualized treatment options.
Do you offer weight loss injections like semaglutide and tirzepatide?
Lake Forest Regenesis evaluates patients for prescription weight-management therapies that may include semaglutide- or tirzepatide-based treatment when clinically appropriate. Your provider will determine which options may be appropriate based on your health and treatment goals.
How quickly will I lose weight?
Weight-loss response varies based on the individual, treatment selected, starting health, lifestyle, and other factors. We focus on steady, medically monitored progress rather than promising a specific rate or amount of weight loss.
Are weight-loss medications safe?
Prescription weight-management medications have potential benefits, side effects, contraindications, and risks. Medical evaluation and ongoing monitoring help determine whether treatment remains appropriate for an individual patient.
Do I still need to focus on nutrition and exercise?
Yes. Prescription medication does not replace healthy eating, physical activity, sleep, and other lifestyle factors. NIDDK recommends using weight-management medications as part of a broader lifestyle program.
What happens when I reach my weight loss goal or stop medication?
When you reach your goal, your plan may shift to long-term weight maintenance. Some patients continue medication, while others transition based on their progress, health, and individual needs.
Your provider will help develop a maintenance plan focused on sustainable habits and reducing the risk of weight regain.
