Try This Muscle-Building Diet Plan For Better Results From The Gym

Pack on muscle with this week-long high-protein diet plan

10 Sep 2020

When you’re trying to build muscle, what you do in the kitchen is just as important as what you do in the gym. Protein is the key, which is why we’ve brought you this high-protein meal planner – taken from New Body Plan Plus, which along with this gym training plan for building muscle can help you increase your muscle mass. The combination of gym and meal plan is best used by experienced gym-goers who are looking to make a concerted effort for a short period of time, but the meal plan can be used by anyone looking to support their training.

This week-long eating plan contains plenty of protein to support your efforts in the gym while also containing the right balance of nutrients to help you get lean. The more closely you can stick to your meal plan the better, but if you can’t make a particular meal then you can substitute in another meal from the same time of day from the same week. If you miss a meal (or multiple meals), don’t worry about it, just carry on with the plan.

To make following the meal plan easier, consider doing a big shop to line up everything you need. To help, we’ve collated a shopping list after the recipe section below. Give it a browse and you’ll pick up a few great healthy diet tips even if you don’t commit to the plan. Those tips include opting for wholemeal carbs, making sure fruit and veg dominate your trolley, picking up nuts and seeds, eating fish a few times a week and varying your sources of animal protein.

Mighty Turkey Burgers

Prep time 10min Cooking time 15min

You probably didn’t expect to see burgers in this plan, did you? The thing is, there’s nothing inherently bad about a burger. The thing that’s unhelpful about the way they’re usually served is the massive bun and big portion of fries, which contain a lot of calories but not much in the way of useful nutrients. Cook them like this, though, and you’ll be able to enjoy the taste while staying on track with your goals.

Ingredients (serves one)

  • 300g turkey mince
  • 15g porridge oats
  • 1 egg
  • ¼ onion, finely diced
  • ½tsp chilli flakes
  • 100g green beans
  • 1tbsp rapeseed oil
  • Small portion of oven chips

To make

  1. Cook the diced onion in a little rapeseed oil, then remove from the pan and allow it to cool.
  2. Place the turkey mince in a mixing bowl, then crack an egg into the bowl and add the oats and chilli flakes.
  3. Once the onions have cooled, add them to the mixture. Season with salt and pepper and mix it all together so the ingredients combine evenly.
  4. Scoop out a small handful of the mixture and roll it into a compact ball in your hands, then place the ball on a baking tray. With the palm of your hand, press the ball down so that it forms a flat patty about 2.5cm thick. Repeat this process until you have used all of the mixture.
  5. Grill the burgers for five to seven minutes, then turn and cook for a further five minutes or until the patties are cooked through.
  6. Serve with the green beans and a small portion of oven chips.

Power Prawn Curry

Prep time 5min Cooking time 25min

You probably don’t automatically think of curry as a healthy food. That’s partly because a lot of them are made with generous quantities of butter and cream, and they’re also often washed down with a few pints of lager. But there are many ways of making curries and lots of them fit easily into the way you’d like to eat while you’re following your New Body Plan. Even better, it’s also possible to make them in a way that’s both quick and tastes great.

Ingredients (serves one)

  • 150g king prawns
  • ½ onion, diced
  • 1 garlic clove, crushed
  • 2 large tomatoes, chopped
  • 1tsp rapeseed oil
  • ½tsp chilli powder
  • ½tsp coriander powder
  • ½tsp ground cumin
  • ½tsp turmeric
  • 1tsp curry paste
  • 75g brown rice

To make

  1. Heat the rapeseed oil in a pan and chop the onion. Add the onion to the pan and fry until golden brown. Add the garlic and reduce the heat.
  2. Add 100ml of water and simmer for about ten minutes.
  3. Add the chilli, coriander, cumin and turmeric and cook for a further five minutes.
  4. Add the prawns and the curry paste and cook for five minutes.
  5. That’s it. You’re done. Just serve with the rice and enjoy!

Chia Seed Power Pot

Prep time 5min Cooking time 2hr

This is a really quick and easy recipe that tastes just like an indulgent treat but will in fact help you to achieve your better-body goals. You can also make it in advance and store it in the fridge. Chia seeds have become increasingly popular in recent years, and with good reason: they’re high in fibre, which can aid digestion and help you feel full, while they also pack a protein punch and are rich in omega 3 fatty acids, which will reduce post-workout inflammation.

Ingredients (serves one)

  • 20g chia seeds
  • 100ml coconut milk
  • 10g clear honey
  • 15g whey protein powder
  • 50g frozen berries

To make

  1. Pour the coconut milk into a bowl.
  2. Next, pour the chia seeds into the bowl and stir so they mix well with the coconut milk.
  3. Pour in the honey and whey protein powder and stir thoroughly so that it mixes evenly.
  4. Put the bowl in the fridge and leave it to set for a couple of hours.
  5. When you’re ready to serve, top it with the frozen berries.

Shopping List

We’ve collated the above and listed it below, including quantities where sensible. However, it’s unlikely you’ll find the exact quantities so portion out what you need when you get home and freeze any excess if you can to avoid unnecessary food waste. Also keep an eye on “best before” and “use by” dates on the fruit and veg so it doesn’t spoil before it’s time to eat it.

While your local supermarket may stock whey protein, you can often find better value online. We’ve tested enough to create a comprehensive list of the best protein powders, but our quick recommendations are Myprotein Pro THE Whey+ and, for a more affordable option, Bulk Powders Pure Whey Protein.
