Struggling With Weight Loss? You’re Not Alone

Losing weight can feel like a constant uphill battle—cutting calories, fighting cravings, and staying energized all at once. Many of our patients at Call-On-Doc share the same story: they’re doing their best but still feel stuck.

Here’s the truth: sometimes it’s not about eating less, it’s about eating smarter. And one of the smartest moves you can make is increasing your protein intake.

In this guide, we’ll cover:

  • Why protein is a game-changer for fat loss

  • How much protein you should eat every day

  • The top 10 protein shakes on Amazon ranked for flavor, weight loss, and meal replacement

  • How Call-On-Doc can support your weight loss journey

Why Protein Helps With Weight Loss

  1. Boosts Metabolism – Your body burns more calories digesting protein than carbs or fat.

  2. Reduces Hunger – Protein keeps you full and helps curb late-night snacking.

  3. Protects Muscle – Losing weight shouldn’t mean losing strength. Protein preserves lean muscle while burning fat.

  4. Improves Recovery – Whether you’re walking more or hitting the gym, protein speeds muscle repair.

*TIP: From a provider’s perspective patients often notice that when they focus on protein, they feel more satisfied, less tired, and more consistent with their goals.

How Much Protein Do You Need Per Day?

A good daily guideline is:

  • Sedentary lifestyle: ~0.8 grams per pound of body weight

  • Active or trying to lose weight: ~1–1.2 grams per pound

Example: A 160 lb active person would aim for 130–190 grams per day.

That may sound like a lot, but shakes make it easy to close the gap without cooking every meal.

When to Use Protein Shakes

  • Busy mornings: Swap cereal or pastries for a high-protein shake.

  • Post-workout: Refuel muscles and prevent soreness.

  • Snack replacement: Stops you from grabbing chips or sweets.

  • Meal replacement: Great for lunch at work or on the go.

At Call-On-Doc, we see the biggest success when patients use shakes to replace high-calorie snacks or skipped meals.

Why Your Hair Falls Out More in Winter

If you’ve noticed extra shedding in the shower, on your pillow, or in your brush during the winter months, you’re not imagining it. Hair loss often increases in fall and winter, and the reasons have less to do with genetics and more to do with seasonal stress on the scalp, hormones, and overall health.

Winter changes your environment in ways that quietly affect the hair growth cycle. Understanding what’s happening inside your body can help you prevent shedding — and support healthier, stronger hair.

❄️ 1. Dry Winter Air Weakens the Hair Shaft

Cold, dry air pulls moisture out of your skin and hair. Because the hair shaft loses hydration faster in low humidity, strands become:

  • brittle

  • frizzy

  • prone to breakage

  • more likely to split

This isn’t true “hair loss” from the root — but breakage can mimic shedding.

Indoor heating makes it worse by lowering humidity even more, leading to dry scalp and fragile strands.

🌬️ 2. Your Scalp Also Dries Out (A Hidden Cause of Shedding)

A dry scalp can become:

  • itchy

  • flaky

  • inflamed

Inflammation disrupts hair follicles, pushing more strands into the telogen (shedding) phase of the cycle.
Conditions like dandruff and seborrheic dermatitis flare in winter, which accelerates shedding.

🌞 3. Lower Sunlight = Lower Vitamin D = More Hair Loss

Vitamin D plays a direct role in hair growth. In winter, sunlight exposure drops drastically, and vitamin D levels fall.

Low vitamin D is strongly linked to:

  • increased shedding

  • slower regrowth

  • weaker hair follicles

Many people don’t realize that winter hair loss can be a simple reflection of seasonal vitamin D deficiency.

🍽️ 4. Winter Nutrition Changes (More Comfort Food, Less Protein)

Cold weather shifts appetite and habits. People tend to eat:

  • fewer fruits and vegetables

  • fewer protein-rich meals

  • more carb-heavy or comfort foods

Hair is made of keratin — a protein — so inadequate protein quickly affects the growth cycle.

Even small nutritional shifts can trigger telogen effluvium, a temporary but noticeable shedding phase.

😴 5. Stress, Illness, and Post-Viral Shedding Are More Common in Winter

Winter brings:

  • colds

  • flu

  • RSV

  • COVID

  • increased stress

  • poor sleep

Any illness or major stressor can trigger hair shedding 2–3 months later.
This means March hair loss might actually come from a December flu.

Winter also increases cortisol levels due to less sunlight and more indoor time, which contributes to hair cycle disruption.

💧 6. Dehydration — One of the Most Overlooked Causes

Most people drink less water in winter.
But dehydration affects:

  • scalp health

  • oil production

  • hair shaft strength

  • follicle function

A dehydrated scalp can’t support healthy growth, and the hair becomes brittle and prone to breakage.

🔁 7. Natural Seasonal Shedding Patterns

Studies show humans shed slightly more hair in fall and winter — an evolutionary response to thicker summer growth and colder weather patterns.

Seasonal shedding is normal, but winter stressors can intensify it.

🔨 Why All-or-Nothing Thinking Backfires

Your brain is wired to conserve energy and avoid discomfort.
All-or-nothing routines demand maximum effort — every day, without exception. That creates pressure the brain sees as a threat.

When you inevitably slip (because you’re human), the brain reacts with:

  • guilt
  • frustration
  • shame
  • avoidance
     

This creates what psychologists call a failure cascade:

  1. One slip →
  2. Guilt →
  3. Avoidance →
  4. Quitting
     

This cascade is why people abandon:

  • gym routines
  • hydration goals
  • strict diets
  • sleep schedules
  • meditation streaks
  • digital detox attempts
     

Perfection isn’t sustainable — and your brain knows it.

Why Sugar Cravings Spike in Winter

If your sugar cravings feel stronger in January, you’re not imagining it — and you’re not doing anything wrong. Cold weather, darker days, disrupted routines, and holiday habits all create the perfect storm for increased carb and sugar cravings.

These cravings aren’t a lack of willpower. They’re biology. Your body is responding to temperature, hormones, mood, and changes in routine — all of which naturally shift during winter. Let’s break down why cravings rise this time of year and how to manage them without restriction, guilt, or harsh dieting.
