You’ve enjoyed the summer but has it left you a little more sluggish and lethargic than you’d like? If your healthy diet derailed during the hotter months, our 21-day meal plan will get you back on track…

The summer months are often a time for celebration, social gatherings and, of course, lots of food and calorie-laden beverages. In fact, our summer holidays are not always as healthy as we might think, with all-you-can-eat buffets, plenty of cocktail hours and restaurant portion sizes, not to mention changes to your regular exercise programme. So if the warm-weather months have left you feeling a bit bloated and sluggish, it’s time to take action and get back on track with a healthy & nutritious meal plan…

How to get back on track with healthy eating

Ready to get back on track with your healthy eating? Hold back from jumping on the weighing scales or starting the latest fad diet. For long-term success when it comes to healthy weight loss, you need to adopt an eating pattern that is both enjoyable and sustainable.

There are no magic foods when it comes to weight loss. If you want to reach a healthy weight, you need to sustain a caloric deficit and, ideally, combine it with an exercise programme tailored to your goals, but you can be flexible. In fact, strict adherence to a healthy meal plan isn’t necessarily for everyone. With that in mind, here are some nutritional strategies that are likely to help you reach a healthier weight for your body type…

Avoid huge calorie deficits

While it is well known that calorie deficit leads to fat loss, don’t fall into the mistake of thinking that ‘less is better’. A huge calorie deficit will just leave you feeling constantly hungry, irritable and too tired to work out effectively. Take a longer-term view – weight loss takes time, so focus on nourishing and energising your body.

Prep meals in advance

If you often eat out, travel for business or work long hours, it’s a good idea to start planning your meals. Meal prep and planning is a great way to save you time and money, plus ensure you have correct portion sizes. If you are eating out, take some time to find a restaurant with healthy options. A little planning will help you stay on track.

Relax your approach to healthy eating

When you’re starting out on a new exercise programme or diet it can be easy to put too much focus on hitting your numbers every day, whether that’s calories or macros. Not only is this mentally draining but it isn’t always necessary – even food labels aren’t 100 per cent accurate. What is more important is consistency. If you do want to initially count or weigh food, then focus on total daily calories and protein, but don’t stress out too much about being perfect.

Don’t be too prescriptive

For many people, following a diet means deprivation which can, in turn, result in a low mood and poor adherence to the plan. Yes, you’re going to need to put in some effort to make healthy changes but there is no reason why you cannot allow for some small indulgences from time to time. This is likely to help you adhere to your plan over time and also avoid a tendency to binge.

Don’t focus on numbers and stats

While you may be looking to see a different number on the scales, if you are exercising regularly, you may find your body looks better despite not losing much weight. This is particularly true if you have started resistance training.

Often you may notice changes in the mirror or in the way your clothes fit. The body also does not lose weight in a linear fashion. That means on some weeks you’ll lose weight, while on others the scale stats won’t change. Water intake, glycogen depletion, sodium intake and hormonal changes can all cause changes to your bodyweight. If your only focus is the scales, you may be tempted to give up when you don’t appear to get results.

5 simple ways to follow a healthier diet

1. Avoid calorific drinks

Liquid calories tend to be far less satiating than solid calories and, typically, are consumed in addition to meals. It’s not just the alcoholic drinks or sugary smoothies in the cafés either – calories from milky drinks, lattes and fruit juices can easily add up, as well.

2. Choose healthier condiments

Calorie-dense vinaigrettes, sauces and full-fat dressings may well be adding 100-200 extra calories to your meals. Switch to low-fat or low-calorie versions, and reduce your portions or drizzle salads with a little vinegar instead.

3. Avoid constant snacking (and choose healthier options)

Eating little and often to lose weight is just not necessary. Snacking can be many people’s downfall. Reducing your meal frequency could help cut the calories and avoid mindless eating.

4. Fill up on veggies

That does not mean no carbs, but instead swap some pasta or bread for leafy greens. This can help you feel full by giving you loads of food volume on the plate and reducing the calories.

5. Focus on protein

When putting meals together, focus on getting sufficient protein-rich foods. This is really key when it comes to body composition. Protein will also keep you feeling fuller for longer, meaning you’re less likely to want to snack later.

21-day healthy meal plan

Do you like to follow a set plan? Each day for the next three weeks, select one of the breakfast options and one snack option below, in addition to the main meals. Many of the snacks and breakfast options are portable or grab-and-go food for convenience. You can be flexible. Some people like the same breakfast daily, while others want more variety.

The dishes on this 21-day healthy meal plan are high in protein, which is important when it comes to fat loss and body composition. Drink six-to-eight glasses of water daily, in addition to your pre-or post-workout electrolytes. And remember to exercise daily and schedule regular resistance training throughout the week, too.
