The Weight Loss Guide
What actually works, explained honestly
You've probably tried dieting before. Maybe it worked for a while, then stopped. Maybe it never worked at all. This isn't another lecture about eating less and moving more—it's an honest look at why weight loss is hard, what your real options are in 2025, and how to pick the right approach for you.
Why this guide exists
The Thermostat Effect
See why “eat less, move more” fails. Drag the slider to lose weight and watch what happens to your hunger.
Personalize Your Plan
Enter your details below and every number on this page—calories, protein targets, timeline, even which path we recommend—will be calculated specifically for you.
Your Options
There's no single right path. Choose based on your situation, and know that you can combine approaches.
The Lifestyle Path
This is the foundation that everything else builds on. Even if you take medication, you'll need these habits. The good news: these changes help with more than just weight—energy, sleep, mood, and long-term health all improve. The lifestyle approach works best if: • You have 10-30 lbs to lose • You haven't really tried a structured approach before • You want to avoid medication • Cost is a major factor
- Prioritize protein at every meal (keeps you full, protects muscle)
- Add resistance training 2-3x per week (more on this below)
- Fix your sleep (seriously—poor sleep sabotages everything)
- Build sustainable habits instead of following a strict "diet"
- Extreme calorie restriction (under 1200 calories backfires)
- Cutting out entire food groups
- Relying only on cardio
- Expecting results in 2 weeks
The Medication Path
New medications (like Ozempic, Wegovy, Mounjaro) have changed the game. They work by reducing appetite at the brain level—not through willpower, but through biology. For many people, they make weight loss dramatically easier. Medication might be right for you if: • You have 30+ lbs to lose (or a BMI over 30) • You've tried lifestyle changes and hit a wall • You have weight-related health issues (diabetes, high blood pressure) • Your hunger/cravings feel uncontrollable These aren't "cheating"—they're treating obesity as the medical condition it is.
- Talk to a doctor about whether you qualify
- Understand the costs (can be $300-1000+/month)
- Still prioritize protein and exercise (the meds help, but you do the work)
- Commit to the long haul—these often need to be taken indefinitely
- Buying from sketchy online sources
- Skipping the lifestyle basics because "the pill will handle it"
- Expecting miracles without effort
- Stopping abruptly without a plan
The Combined Approach
The most effective approach? Combining lifestyle changes with medication support. The medication makes it easier to eat less, while the lifestyle changes protect your muscle, boost your metabolism, and set you up for long-term success. This approach makes sense if: • You want the best possible results • You can afford medication and are willing to commit • You're ready to make real lifestyle changes too • You have significant weight to lose
- Start medication under medical supervision
- Immediately prioritize protein (1g per pound of goal weight)
- Add resistance training to prevent muscle loss
- Use the reduced appetite to build better eating habits
- Thinking medication alone is enough
- Neglecting protein (you'll lose muscle along with fat)
- Skipping strength training
- Going too fast—sustainable beats fast
Your Toolkit
Understanding Your Numbers
How much should you aim to lose?
A healthy target is 5-10% of your current weight over 6 months. For someone at 200 lbs, that's 10-20 lbs. More is possible, but slower is more sustainable.
How fast is healthy?
1-2 lbs per week is the sweet spot. Faster than that usually means you're losing muscle too, which tanks your metabolism and leads to regain.
How much protein do you need?
Research shows 1.2-1.6g per kg of body weight (or ~0.7-0.8g per pound) preserves muscle during weight loss. For a 180 lb person, that's 120-145g of protein per day.
How much of a calorie deficit?
A 500-calorie daily deficit leads to ~1 lb/week loss. But don't go below 1200 calories (women) or 1500 (men) without medical supervision.
The Basics That Actually Matter
Helpful (But Not Essential)
Daily Routine
Protein-forward breakfast
Start with 25-30g protein: eggs, Greek yogurt, cottage cheese, or a protein shake. This reduces hunger for hours and sets a good pattern for the day.
Balanced lunch + movement
Protein + vegetables + some carbs. Then a 10-15 minute walk if possible. Post-meal walks help with blood sugar and add to your daily steps.
Protein-rich snack if needed
If hungry between meals, reach for protein: jerky, cheese, Greek yogurt, hard-boiled eggs. Avoid the vending machine.
Dinner + possible workout
Another 30-40g protein at dinner. If you exercise, evenings work well for most people. Even a home workout with resistance bands counts.
Wind-down routine
Stop eating 2-3 hours before bed. Dim lights, limit screens. Consider magnesium for sleep quality. This is when your body recovers and regulates hunger hormones.

GLP-1 Medication Side Effects
Most people experience some side effects when starting GLP-1 medications like Ozempic or Mounjaro. Here's what to expect and how to manage them.
Good news: most GI side effects improve significantly after 4-8 weeks as your body adjusts. They also tend to return temporarily after each dose increase.
When to Seek Emergency Care
Stop your medication and seek immediate medical care if you experience: severe stomach pain that doesn't go away, persistent vomiting, signs of allergic reaction (rash, difficulty breathing, swelling), or symptoms of thyroid tumors (lump in neck, difficulty swallowing, hoarseness).
Nausea
Feeling queasy, especially in the first few weeks and after dose increases. Usually worst in the mornings or after eating too much.
How to manage it:
Eat smaller, more frequent meals. Avoid greasy or heavy foods. Ginger tea or ginger chews can help. Stay hydrated. Some people find eating bland foods (crackers, toast) helps.
Constipation
Slower digestion means things move slower through your system. This is one of the most persistent side effects.
How to manage it:
Increase fiber intake gradually. Drink plenty of water (this is critical). Consider a stool softener like Miralax. Magnesium supplements can help. Stay active—movement helps digestion.
Diarrhea
Some people get diarrhea instead of constipation, especially early on. It usually resolves on its own.
How to manage it:
Stay hydrated. Avoid high-fat or greasy foods. Consider probiotics. Usually improves within a few weeks.
Fatigue
Feeling more tired than usual, especially in the first few weeks. Often related to eating less.
How to manage it:
Make sure you're eating enough (at least 1200-1500 calories). Check your protein intake. Stay hydrated. Prioritize sleep. If severe, your dose may need adjustment.
Headaches
Headaches in the first few weeks are usually related to dehydration or eating too little.
How to manage it:
Drink more water (aim for 64+ oz daily). Make sure you're eating enough. Over-the-counter pain relievers are fine to use.
Injection Site Reactions
Redness, itching, or small bumps at the injection site. Usually minor and resolves quickly.
How to manage it:
Rotate injection sites. Let the medication come to room temperature before injecting. Don't inject into the same spot repeatedly.
"Ozempic Face"
Not a drug side effect per se—it's what happens when you lose fat from your face rapidly. Your face can look more gaunt or aged.
How to manage it:
This is more likely if you lose weight very quickly without adequate protein or exercise. Prioritize protein (preserves muscle), strength training, and don't rush the weight loss. Some people use facial fillers cosmetically.
Gallbladder Problems
Rapid weight loss increases the risk of gallstones. This is true for any rapid weight loss method, not just GLP-1s.
How to manage it:
Lose weight at a moderate pace (1-2 lbs/week). Don't skip meals completely. Keep some healthy fats in your diet.
Pancreatitis
Inflammation of the pancreas. This is rare but serious. More likely in people with a history of pancreatitis.
How to manage it:
Know the warning signs. Stop medication immediately if symptoms occur and seek emergency care.

What GLP-1 Medications Actually Cost
Let's talk money. GLP-1 medications aren't cheap, and navigating the options can be confusing. Here's the reality.
Brand Name with Insurance
If your insurance covers GLP-1s for weight loss (many don't), this is the best option. Prior authorization is usually required.
Pros
- FDA-approved medications from verified sources
- Doctor monitoring included
- Consistent quality and dosing
Cons
- Many insurance plans don't cover weight loss medications
- Prior authorization can take weeks
- May require documented diet/exercise failure first
Brand Name Cash Pay
Paying out of pocket for Wegovy, Ozempic, or Zepbound at retail price. Expensive but guaranteed quality.
Pros
- Guaranteed genuine medication
- Available at any pharmacy
- No insurance hassles
Cons
- Extremely expensive for most people
- Manufacturer savings cards have limitations
- Not sustainable long-term for many budgets
Telehealth + Compounded Semaglutide
Online services that prescribe compounded versions of semaglutide made by compounding pharmacies. A popular middle-ground option.
Pros
- More affordable than brand name
- Convenient—consultations are online
- Still requires prescription and some medical oversight
Cons
- Quality varies between compounding pharmacies
- Not FDA-approved (the compounding, not the molecule)
- Less regulation than brand-name medications
- May need to verify pharmacy credentials yourself
Lifestyle Changes Only
Focusing on diet, exercise, and behavior changes without medication. Free, but requires more willpower.
Pros
- Free (or minimal cost for food/gym)
- No side effects
- Sustainable forever
- Improves overall health beyond weight
Cons
- Slower results for most people
- Fighting against biology without medication support
- May not be sufficient for those with significant weight to lose
- Higher failure rate long-term (statistically)
Ways to Save Money
- Check manufacturer savings programs: Novo Nordisk (Wegovy/Ozempic) and Eli Lilly (Zepbound/Mounjaro) both offer savings cards for eligible patients
- Ask your doctor about samples—many clinics have starter doses available
- If using telehealth services, ask about their pharmacy sources and verify certifications
- Some employers offer weight loss medication coverage as a separate benefit—check with HR
- HSA/FSA accounts can typically be used for prescribed weight loss medications
- If denied by insurance, ask your doctor to file an appeal with documentation of medical necessity
Insurance Tips
- Coverage for "obesity" is more common than coverage for "weight loss"—the diagnosis code matters
- Some plans cover these medications only for diabetes, not weight loss
- Document everything: BMI, comorbidities, previous diet attempts
- If initially denied, appeal—success rates on appeals are surprisingly high
- Ask about "step therapy" requirements (trying cheaper medications first)

Glossary
- Calorie deficit
- Eating fewer calories than you burn. This is required for weight loss—there are no exceptions. A 500-calorie daily deficit leads to about 1 lb of weight loss per week.
- NEAT
- Non-Exercise Activity Thermogenesis. All the calories you burn through daily movement that isn't formal exercise—walking, fidgeting, standing, taking stairs. Can account for 15-30% of your daily calorie burn.
- Maintenance calories
- The number of calories you need to maintain your current weight. Eat below this to lose weight, above it to gain. This number decreases as you lose weight.
- Body recomposition
- Losing fat while maintaining or gaining muscle. The scale might not move much, but you'll look and feel different. Requires adequate protein and resistance training.
- Metabolic adaptation
- Your body's response to eating less: metabolism slows down to conserve energy. This is why weight loss slows over time and why "eating less and less" eventually stops working.
- GLP-1 agonist
- A class of medications (Ozempic, Wegovy, Mounjaro) that mimic the GLP-1 hormone. They reduce appetite and slow digestion, making it easier to eat less.
