📋 Myths & Questions About Nutritional Consultation

Do I have to stop eating the foods I love to see results at the gym? +
No, para nada. La clave del éxito está en el balance y el equilibrio adaptado a tus necesidades y objetivos diarios. No existen alimentos "buenos" ni "malos" por sí solos; lo que realmente importa es cómo distribuimos lo que tu cuerpo necesita para rendir al máximo y lograr tus metas sin sufrir en el proceso.
I've never seen a nutritionist — what should I expect from my first consultation? +
At ALFA Nutrición & Fitness we take the time to truly know you. In your first consultation we'll build your complete clinical file, take anthropometric measurements, and evaluate your blood pressure, oxygenation, and heart rate. We'll also use InBody bioimpedance technology to get a detailed analysis of your body composition (fat and muscle). With this precise data, we'll build a truly personalized nutrition plan.
If my goal is to lose weight, will I go hungry on the diet? +
Uno de mis principales objetivos profesionales es derribar el mito de que estar en un déficit calórico es sinónimo de pasar hambre. Al ajustar tu plan de manera inteligente, estableciendo márgenes de tiempo estratégicos y utilizando técnicas de saciedad alimentaria, logramos mitigar por completo esos periodos de ansiedad y hambre.
How often should I schedule follow-up consultations to track my progress? +
Ideally, every 28 to 32 days — enough time to evaluate adherence and record real changes in anthropometry and bioimpedance. In each follow-up session we analyze your progress and adjust strategy so you keep moving forward. Later, check-ins can be spaced to every 2–3 months depending on your goals or medical condition.
Does the consultation include a strict menu, or do you teach me to build my own meals? +
My approach is based on nutritional education so you build habits that stay with you for life. During the first consultations, I'll fully guide your menu structure. As you show adherence and get familiar with your portions, I'll give you tools and support materials so you learn to build your own meals completely independently.
I have a medical condition (hypothyroidism, diabetes, insulin resistance) — will the plan adapt to me? +
Por supuesto. El plan de alimentación es 100% adaptable. Atiendo desde personas sanas que buscan mejorar su estilo de vida y deportistas enfocados en el alto rendimiento, hasta pacientes clínicos con enfermedades crónico-degenerativas, necesidades gineco-obstétricas o en etapas de preparación pre y postoperatoria.
Why isn't the scale going down if my clothes feel looser and I'm training more? +
The number on the scale fluctuates for many reasons: normal muscle inflammation from exercise, fluid retention, lifestyle, or even the season. What's really happening is body recomposition — you're losing fat mass and gaining muscle mass at the same time. That's exactly why your clothes fit better even though the weight hasn't changed!

🏋️ Fitness & Performance Nutrition

What's best to eat before and after training to fuel performance and recover muscle? +
To perform at your best, the ideal is a strategic pre-workout snack (easy to digest, carb-rich) adapted to your activity intensity. After training, we'll prioritize a complete meal rich in macronutrients (quality protein and recovery carbohydrates) to ensure optimal muscle rebuilding and rest.
Is protein powder mandatory if I want to gain muscle mass? +
No, no es obligatorio. Recuerda que la proteína en polvo es únicamente un complemento alimentario. Lo que realmente determina tus resultados es la calidad, la variedad y las porciones de la comida real que consumes a lo largo del día.
What's the real difference between a fat-loss plan and a muscle-gain plan? +
La diferencia clave radica en las calorías y la distribución de macronutrientes. Para perder grasa, buscamos un déficit calórico controlado para que tu cuerpo utilice sus reservas de grasa como energía. Para aumentar masa muscular, requerimos un ligero superávit calórico que aporte al cuerpo el "material de construcción" necesario para reparar y crear tejido muscular nuevo, acompañado siempre de un consumo adecuado de proteína.
Do I have to count calories and weigh my food to see physical changes? +
Yes, it's essential at the start. Weighing your food is the only objective tool that guarantees you're consuming the exact portions your body needs to change. Real progress and goal control begin with precision in your kitchen.
How important are carbohydrates if I do strength training? +
Son cruciales. Los carbohidratos son la fuente de energía principal para tu cerebro y tus músculos. Te permiten entrenar con fuerza, intensidad y recuperarte adecuadamente para tus actividades diarias, siempre calculados en las porciones óptimas para tu cuerpo.
How can I avoid fatigue or energy crashes in the middle of my workout? +
The best way to avoid it is to consistently follow your daily nutrition plan. Together, we'll design a pre-workout strategy focused on keeping your glycogen and energy levels stable throughout your entire workout session.
¿Qué son los "macros" (macronutrientes) y cómo influyen en mis metas fitness? +
They are the three main nutrients the body needs in large amounts: Proteins: the building blocks that repair and create muscle. Carbohydrates: the main fuel for your muscles and brain. Healthy fats: your energy reserve, key for hormone production and absorption of fat-soluble vitamins (A, D, E, K). All three must work in perfect synergy to reach your physical goals while maintaining your health.
If I train at night, will eating carbs for dinner make me gain weight? +
No, ese es uno de los mitos más comunes en el fitness. El cuerpo no almacena los carbohidratos automáticamente como grasa solo porque sea de noche; los metaboliza y los distribuye hacia el cerebro y los músculos para promover la recuperación y recargar tus depósitos de energía para el día siguiente.

💊 Supplementation & Ergogenic Aids

Does creatine really work? Does it have side effects or damage the kidneys? +
Yes, it really works. It's one of the most scientifically backed supplements in the world. It increases strength, promotes muscle mass gain, improves explosive exercise performance, and offers cognitive benefits (especially in older adults). It produces no side effects in healthy people at correct doses. Come see me to calculate the exact grams you need.
What are the basic supplements actually worth it for someone starting out in fitness? +
If you're just starting out, the only basic supplements truly worth considering are protein powder and creatine. However, it's essential to first master a solid nutritional foundation before adding them.
Do fat burners work on their own, or are they a myth? +
Son un mito. No existe ningún suplemento que queme grasa de forma pasiva o por sí solo. Además, muchos de estos productos contienen estimulantes en exceso que pueden provocar efectos secundarios desagradables o riesgos para tu salud. El único "quemador" real es un déficit calórico bien estructurado.
Is it bad to take caffeine or pre-workouts before my daily workout? +
Consuming caffeine in moderate amounts (like a cup of coffee) is not harmful and is an excellent performance aid. However, be cautious with commercial pre-workout supplements, as they often contain aggressive stimulant blends that can cause side effects like tachycardia, anxiety, or insomnia.
Are BCAAs necessary if I'm already taking protein powder? +
They're not necessary. If you're already consuming quality protein powder and eating a balanced diet, you're already covering all the amino acids your body needs to recover. Don't overspend.

🥦 Habits, Lifestyle & Sustainability

What do I do if I have a social event or dinner on the weekend without ruining my progress? +
La clave es la flexibilidad. Intenta buscar dentro de las opciones disponibles del menú un platillo que se asemeje lo más posible a las porciones y macros de tu comida correspondiente. Disfruta el momento con moderación y recuerda que una comida fuera de plan no arruinará tus semanas de esfuerzo.
How can I control sugar cravings or the urge to eat in the afternoon/evening? +
There are several nutritional strategies for this, but one practical and highly effective tool to control the urge to munch is keeping fresh vegetable snacks on hand (like cucumber, jicama, or carrots) with lime juice or low-sodium chili powder.
If I miss a workout or skip my diet for a day, what should I do the next day? +
Simplemente retoma tu plan de alimentación y tu entrenamiento con total normalidad al día siguiente. No te culpes ni intentes "compensar" dejando de comer o haciendo ejercicio en exceso; la constancia a largo plazo pesa mucho más que un tropiezo de un solo día.
¿Es malo hacer el famoso "Cheat Meal" (comida trampa) una vez a la semana? +
Puede llegar a ser contraproducente si aún no has consolidado una base de buenos hábitos alimenticios. Lo ideal es que lo platiquemos en consulta para diseñar una estrategia personalizada que te permita disfrutar de tus comidas favoritas sin frenar tu progreso.
How much water should I actually drink if I'm active and exercise regularly? +
There's no single number for everyone. It largely depends on your daily habits, training intensity, and even the weather and season. In your consultation we'll calculate your personalized hydration requirement.
How important is rest and quality sleep for seeing gym results? +
Rest is a fundamental pillar. It's during deep sleep that your body initiates cellular recovery and muscle-building processes. Ideally, aim for 7 to 8 hours of quality sleep each night to consolidate your results.

🩺 Clinical Nutrition (Health, Overweight & Chronic Disease)

I'm overweight or obese and have difficulty moving — can I start a nutrition plan before beginning heavy exercise? +
Sí, totalmente. Cuando el nivel de sobrepeso es elevado, el enfoque inicial debe concentrarse al 100% en la alimentación. Una vez que logremos reducir el peso y disminuir la carga sobre tus articulaciones, comenzaremos a incorporar de forma segura actividad física de bajo impacto para evitar cualquier tipo de lesión o molestia en tus rodillas.
I have Type 2 Diabetes (or insulin resistance) — will your plan help me control my glucose without relying solely on medication? +
When a doctor has already prescribed medication, maintaining it is vital. What we'll do with nutrition is create the perfect metabolic support so that, alongside your medication, you achieve optimal and stable blood glucose control, preventing any future complications.
I was diagnosed with hypertension or high cholesterol — what specific dietary changes will we implement to protect my heart? +
We'll implement a low-sodium, Mediterranean-style strategy, prioritizing healthy fatty acids (like omega-3) and quality fiber. Everything will be perfectly balanced to your personal tastes, ensuring you care for your cardiovascular health while enjoying your food.
I suffer from frequent digestive problems (colitis, gastritis, inflammation) — will a fitness nutrition plan be hard on me or can it adapt? +
Si presentas afecciones digestivas, una dieta "fitness" convencional de internet no es para ti. Tu cuerpo necesita una terapia nutricional digestiva específica que atienda, desinflame y repare tu sistema gastrointestinal antes de exigirle un rendimiento deportivo. Evita seguir menús genéricos de redes sociales que solo complican tu salud; aquí diseñamos un plan noble con tu digestión.
How does professional nutrition help regulate hormonal issues like Polycystic Ovary Syndrome (PCOS) or hypothyroidism? +
For PCOS, nutrition reduces insulin resistance, decreases systemic inflammation, and helps regulate androgen levels. For hypothyroidism, the plan focuses on providing key nutrients for thyroid function, avoiding interference with levothyroxine absorption, combating symptoms like constipation and fatigue, and maintaining healthy weight control.
He intentado muchas dietas antes y siempre sufro el "efecto rebote", ¿por qué este enfoque clínico y de fitness va a ser diferente? +
Porque yo no te ofrezco una dieta temporal restrictiva o repetitiva. Mi propuesta es darte herramientas de educación alimentaria para toda la vida. Te enseñaré a comer de forma balanceada y flexible para que logres un estilo de vida sostenible, blindándote por completo contra el temido "efecto rebote".
My doctor told me I have fatty liver — is it possible to reverse this condition by changing my diet and habits alone? +
Sí, en etapas tempranas es completamente reversible. Es de suma importancia actuar rápido, ya que actualmente no existe un medicamento específico que cure el hígado graso no alcohólico; el único y más potente tratamiento disponible es la reestructuración de tus hábitos alimenticios y tu estilo de vida.
Are nutrition plans for people with chronic diseases boring and bland, or will I still eat delicious food? +
Not at all boring. Menus are built respecting your tastes, preferences, and the ingredients you enjoy. I'll teach you how to make delicious, dynamic combinations from day one to avoid monotony and show you that caring for your health is also a culinary pleasure.
