My top nutrition tips for fat loss

My Top Nutrition Tips for Fat Loss – Jason Isaacs Personal Training.

When it comes to fat loss, training is important – but your nutrition is where the real transformation happens. At Jason Isaacs Personal Training in Brighton and Hove, I work with clients both in person and online to help them achieve sustainable fat loss by focusing on smart, consistent nutrition habits. Here are my top nutrition tips to help you lose fat effectively while maintaining muscle mass and energy levels.

🔥 1. Understand the Power of a Calorie Deficit

To lose body fat, you must consume fewer calories than you burn – it's that simple. However, it’s important that the deficit isn’t extreme. A sustainable calorie deficit (roughly 15–25% below maintenance) allows you to lose fat while holding onto lean muscle. I help clients calculate and adjust their calorie needs based on progress and goals.

🧮 2. Track Calories and Macros Accurately

Guesswork doesn’t cut it. Using apps like MyFitnessPal can help you stay on top of what you're really eating. Be honest with things like oils, sauces, drinks, and snacks – they add up fast! Tracking macronutrients (protein, carbs, fats) is just as important as calories, especially for maintaining muscle during fat loss.

🥩 3. Prioritise Your Protein

Hitting your daily protein goal is essential. Protein helps preserve lean muscle mass, keeps you feeling fuller for longer, and supports recovery from training. When you're in a calorie deficit, aim for 1.6–2.2g of protein per kg of bodyweight per day.

🍳 4. Don’t Fear Carbs or Fats

Healthy fats and carbohydrates play an important role in hormone health, brain function, energy, and performance. Choose complex carbs like oats, rice, sweet potatoes and whole grains, and healthy fats like nuts, seeds, avocados, and olive oil.

🥗 5. Choose Low-Calorie, High-Volume Foods

Fill your plate with foods that provide lots of volume but fewer calories – things like leafy greens, vegetables, berries, and lean proteins. These help you stay fuller for longer without blowing your calorie budget.

🥤 6. Stay Hydrated

Water is often overlooked, but it plays a key role in fat metabolism and appetite control. Aim for 2–3 litres per day, more if you're active. Sometimes what feels like hunger is actually dehydration.

🍱 7. Plan and Prep Your Meals

Meal prep reduces the chance of grabbing high-calorie convenience foods when you're busy or tired. Planning your meals also helps with macro balance and portion control. I always encourage clients to prep their meals ahead where possible – it’s a game-changer for consistency.

📈 8. Be Consistent

Fat loss doesn't happen overnight. Sticking to your calorie and macro goals consistently over weeks and months is what brings results. I support clients with ongoing accountability and check-ins to stay on track.

🏋️‍♂️ Fat Loss While Maintaining Muscle

The goal isn’t just to lose weight – it’s to lose fat and hold onto muscle. That’s why combining proper nutrition with strength training is key. At Jason Isaacs Personal Training Brighton, I coach clients through both – helping them hit their targets while staying strong and healthy.

Why Using a Calorie Tracking App Like MyFitnessPal is Essential for Weight Loss

Why Using a Calorie Tracking App Like MyFitnessPal is Essential for Weight Loss

If you're trying to lose weight, the most important principle to understand is this: you need to be in a calorie deficit—burning more calories than you consume. While this sounds straightforward, the reality of managing your intake consistently is where most people struggle. That's why using a calorie tracking app like MyFitnessPal is a game-changer, and something I recommend to all my clients at Jason Isaacs Personal Training in Brighton and Hove 

Why Tracking Matters

As a qualified personal trainer in Brighton and Hove, I see many people unintentionally sabotage their fat loss progress by underestimating their daily intake. Whether you're just starting your journey or looking to break through a plateau, tracking your food gives you visibility and control. Apps like MyFitnessPal allow you to log everything you eat and drink, helping you stay on top of your daily calorie target.

Don’t Ignore the Hidden Calories

Small things that often go untracked can make a big difference, including:

Cooking oils and dressings

Sauces like ketchup, mayo, and gravy

Milk in tea or coffee

Alcoholic drinks or soft drinks

Snacks or nibbles while cooking

Even if you’re eating clean and exercising regularly, these untracked extras can quickly tip you out of a calorie deficit. MyFitnessPal makes it easy to account for these items, keeping you honest and consistent.

MyFitnessPal has one of the largest food databases available, making it ideal for accurate logging whether you’re eating at home, out at a restaurant, or picking up a ready meal. You can scan barcodes, import recipes, and track your macros with precision. As a weight loss coach in Brighton, I’ve found that clients who track their food with MyFitnessPal are more likely to hit their goals and understand the impact of their food choices.

Accountability & Awareness

When you’re logging your food daily, you become more aware of what you're consuming—and that awareness is powerful. It creates accountability and gives you a clear understanding of where changes need to be made. For many, just seeing the numbers is enough to rethink that extra glass of wine or late-night snack.

Build Better Habits

You don’t need to track forever, but using an app consistently over a few weeks can help you build lifelong habits. Once you’ve got a feel for portion sizes and calorie values, you'll be able to make better decisions even without the app.

Ready to Take Control?

If you're ready to commit to your fitness journey, using a tracking app is a fantastic first step. Combine that with expert guidance from a qualified personal trainer in Brighton—and you’ve got a proven formula for fat loss success. I offer one-to-one and shared personal training, along with nutritional guidance to help you stay in a calorie deficit and reach your goals.

Fat Loss Through a Calorie Deficit: A Sustainable Guide

Fat Loss Through a Calorie Deficit: A Sustainable Guide

By Jason Isaacs Personal Training – Brighton and Hove

If you’re aiming to lose fat, the most effective and sustainable method is a calorie deficit—eating fewer calories than your body burns each day. No crash diets or fads required—just simple science, applied consistently.

At Jason Isaacs Personal Training in Brighton and Hove, I help clients reach their goals through smart nutrition, tailored workouts, and ongoing support. Here’s how to approach fat loss the right way.

What Is a Calorie Deficit?

A calorie deficit happens when your body burns more energy than it takes in from food. For example, if your maintenance level is 2,500 calories and you eat 2,000, you’re in a 500-calorie deficit.

Consistently maintaining this deficit results in fat loss over time—ideally around 0.5–1kg per week depending on your starting point.

Don’t Lose Muscle—Keep Protein High

One of the biggest mistakes people make during fat loss is under-eating protein. When calories are low, the body can break down muscle for energy—unless you give it a reason not to.

To maintain lean muscle while in a deficit:

Aim for 1.6–2.2g of protein per kg of bodyweight

Include high-protein foods in each meal (e.g. chicken, fish, eggs, tofu, Greek yoghurt.)

Continue strength training consistently

Maintaining muscle keeps your metabolism healthy and improves your body shape as you lose fat.

Track Calories Accurately

Awareness is everything. Most people underestimate what they eat, and that’s where calorie tracking comes in.

Top tool to help you stay on target:

MyFitnessPal – Large UK food database, easy to use

Pro tip: Weigh food with kitchen scales for the most accurate tracking—especially calorie-dense ingredients like oils and nuts.

How Big Should Your Deficit Be?

For long-term success, aim for a 15–25% calorie deficit from your maintenance level. That usually means a 300–500 calorie daily shortfall.

Crash diets or extreme deficits can backfire, leading to fatigue, muscle loss, and binge-eating patterns.

👉 Use a Daily Calorie Calculator to estimate your maintenance calories and set your ideal deficit 

Tips to Help You Stay in a Calorie Deficit

Stay hydrated – Often, hunger is dehydration in disguise. Drink plenty of water throughout the day.

Try black coffee – It can help curb appetite and boost energy without adding calories (skip the extras).

Eat more volume – Fill your plate with high-fibre, low-calorie foods like veg, berries, and lean protein.

Meal prep – Take control of your food environment. It’s easier to stick to your plan when your meals are ready.

Minimise liquid calories – Choose water, herbal teas, or zero-calorie drinks over sugary drinks and alcohol.

Why Sleep is Just as Important as Exercise for Fat Loss and Health

Why Sleep is Just as Important as Exercise for Fat Loss and Health

As a personal trainer in Brighton and Hove – and online – I often talk to clients about training, nutrition, and motivation. But one thing that’s just as important, and often overlooked, is sleep.

If you're aiming to lose body fat, improve your fitness, or simply feel better day-to-day, the amount and quality of your sleep can have a huge impact.

Sleep and Fat Loss

When you don’t get enough sleep, it affects the hormones that control hunger – ghrelin and leptin. Ghrelin increases, making you feel hungrier, while leptin decreases, meaning you don’t feel as full. This leads to more cravings, especially for sugary or processed foods.

Sleep also affects insulin sensitivity, which plays a big role in how your body stores fat – especially around your midsection. Without enough rest, your fat loss efforts can hit a wall.

Sleep and General Health

Getting proper rest helps with:

Immune system function

Mental clarity and focus

Muscle recovery after training

Stress levels and mood

Whether you’re training with me in the gym, outdoors, or online, your body needs sleep to recover, grow, and perform at its best.

How to Improve Your Sleep

Here are a few habits that can help:

Stick to a regular sleep schedule, even on weekends

Avoid screens 30–60 minutes before bed

Keep your bedroom cool, dark, and quiet

Cut back on caffeine after midday

Keep active – regular exercise helps promote better sleep

Final Thoughts

If fat loss, fitness and health are your goals, then sleep is essential. It’s not just about what you do in your workouts – it’s what you do outside the sessions too. I help my clients focus on the full picture: training, nutrition, mindset, and lifestyle.

If you want support with your fat loss, fitness, and healthy habits, I offer one-to-one and shared sessions in Brighton and Hove – or online wherever you are.

Why Hitting Your Protein Goals is Crucial in a Calorie Deficit

Why Hitting Your Protein Goals is Crucial in a Calorie Deficit

When you're trying to lose weight, you likely focus on cutting calories. While this is essential for fat loss, many people overlook the importance of protein intake during a calorie deficit. Ensuring you hit your daily protein target can make a massive difference in muscle retention, metabolism, and overall health.

At Jason Isaacs Personal Training in Brighton and Hove, I work with clients to optimise their nutrition alongside effective training methods. Whether you’re looking to shed body fat, build muscle, or improve performance, protein plays a key role in your success.

Why Protein Matters in a Calorie Deficit

1. Preserves Lean Muscle Mass

When you reduce calories, your body doesn’t just burn fat – it can also break down muscle for energy. Consuming adequate protein helps maintain lean muscle mass, ensuring that the weight you lose comes primarily from fat. This is especially important if you’re weight training, as muscle retention supports strength and definition.

2. Keeps You Feeling Fuller for Longer

One of the biggest challenges of dieting is hunger. Protein is the most satiating macronutrient, meaning it keeps you fuller for longer compared to carbs or fats. This helps prevent unnecessary snacking and cravings, making it easier to stick to your calorie target.

3. Supports Workout Recovery and Performance

Whether you’re lifting weights, boxing, or doing high-intensity training, protein is essential for muscle repair and recovery. A well-balanced protein intake helps you recover faster, reduces soreness, and allows you to train effectively, even in a calorie deficit.

How Much Protein Do You Need?

For fat loss while preserving muscle, a general guideline is:

1.6–2.2g of protein per kg of body weight

For example, if you weigh 70kg, aim for 112–154g of protein per day

If you're unsure about your exact protein needs, I provide personalised nutrition guidance at Jason Isaacs Personal Training in Brighton & Hove to help you optimise your intake based on your goals and training routine.

Best Protein Sources for Fat Loss

To hit your protein goals without excessive calories, focus on lean, high-quality protein sources:

Animal sources: Chicken, turkey, lean beef, eggs, fish, Greek yoghurt, cottage cheese

Plant-based options: Tofu, Quorn, tempeh, lentils, chickpeas, quinoa, edamame, protein powder

Take Your Nutrition to the Next Level

If you’re serious about fat loss but want to retain muscle, boost performance, and feel energised, prioritising protein is essential.
