You need to change your diet, exercise more, and lead an overall healthier lifestyle.
1. Commit to Your Weight Loss Journey
A weight-loss journey with long-term success requires a lot from you.
You need to be ready to give your time, energy, patience, and willingness to pivot when you plateau.
Weight loss takes your time and effort for a very long time.
The following things in your life need to be aligned:
- You are ready for the long-term commitment, you are done with crash diets.
- You have a realistic goal weight you want to ultimately achieve.
- You are able to have a good night’s sleep consistently throughout the week.
- Your stress levels are controlled.
- You can dedicate a workout routine to your weeks consistently.
- You are open to working with a nutritionist and/or personal trainer.
2. Set a Realistic Goal
Setting a goal is easy, but is it a realistic goal?
A goal that will lead you to an ideal weight that is also sustainable, is the direction to go.
Usually, when a person is in the obesity category according to their BMI (Body Mass Index), the recommendation is for that person to lose 5% of their total body weight (1).
Research has shown that losing 5% of total body weight can significantly improve the health of a person (1).
Cholesterol levels can improve, High blood pressure is reduced, the levels that monitor diabetes called HgbA1C also improve (1).
So if you weigh 250 pounds a 5% weight loss will result in 12.5 pounds less, down to 237.5 pounds.
Let’s say you want more than just the 5% weight loss, you want a complete transformation. You need to look at your current weight, create a target weight that you can achieve in the long term.
For example, you weigh 250 pounds but you would be happy at 190 pounds.
Create new goals that are smaller and can be achieved in smaller amounts of time.
3. Drink A Lot Of Water
Water intake is the most important thing you can do for your body.
Your body is made up of about 70% water to cover the needs of cells, blood, tissues, and all kinds of fluids.
A study found that having a low-calorie diet and water intake before eating resulted in 44% more weight loss in a 12-week period.
Also, water is known to have no calories, thus helping you from dehydration and avoiding liquid calories commonly found in juices or other beverages.
You may not think about it, but beverages other than water or unsweetened coffee can pack on some serious calories.
These beverages are a fuel source, but not the type you want since it tends to increase blood sugar levels.
A 12-ounce latte, for example, can be 200 calories, which is the equivalent of a snack.
But this latte contributes little nutrients and a lot of sugar.
A good idea is to drink water before, during, and after mealtime to ensure you are properly hydrated.
Try at your next meal to have a glass of water and see how you fill up faster.
Aim for a daily water intake of at least 2 liters (3).
4. Reduce Carbohydrates
Carbs are very important for your body, but dieters have been drilled that they are bad.
You can find them in a variety of grains but you really want to watch out for refined carbs.
The refined carbs you want to avoid are those that the fiber has been removed, and only the starchy portion remains.
You want to avoid white rice, white bread, sugary snacks, desserts, and processed snacks.
They get easily absorbed into the bloodstream and converted to fat if not used by the body.
Large amounts of refined carbs in the blood stream can cause the body to have spikes of sugar that can over a long period of time cause insulin resistance.
A small study has also found that a diet rich in unrefined carbs led to decreased body weight and inflammatory markers (5).
The best type of carbohydrates you can choose is whole grain.
These can be whole grain bread, whole grain pasta, legumes, quinoa, brown rice, barley, and starchy veggies.
To optimize your carbohydrate intake, you can make a Quinoa salad, Pasta salad, Barley salad.
By making a salad, you decrease the overall calorie intake by increasing veggies and naturally eating less carbohydrates.
5. Increase Proteins
As part of your weight loss journey, protein intake is essential to help you have satiety, control hunger, and repair muscle mass after a workout.
Another small study found that having breakfast rich in proteins reduces ghrelin levels, known as the hunger hormone when you compared it to a high-carb breakfast (2).
Having protein-rich foods or high protein diets can be quite beneficial to your fat loss.
You can get your proteins from plant or animal sources such as legumes, almonds, peanuts, seeds, or lean proteins found in fish, poultry, or lean meats.
Animal products like eggs, cheese and whole milk, cheese and yogurt.
6. Consume More Fiber
Fiber can be found in almost all foods, it is a carbohydrate that is indigestible and used to move food through your gastrointestinal tract.
It is part of a healthy diet in the sense that, it slows down how quickly your stomach empties out, so you feel full longer. It slows down the rate of sugar absorption, preventing those sugar spikes.
Foods rich in fiber are veggies, fruits, whole grains, and legumes.
Veggies tend to have varying levels of fiber, some more and some less.
Having a variety of veggies and fruit in the diet can also bring vitamins and minerals that are essential to the body.
Whole grains and legumes also provide all of the above-mentioned plus proteins.
7. Increase Whole Foods and Healthy Fats
To lose weight in a sustainable way, whole foods are essential to help trim inches off your waistline.
Whole foods are those that are not processed like veggies, salads, legumes, whole grains, and lean meats.
These ensure that a variety of all macronutrients (carbs, protein, fat) and micronutrients (vitamins and minerals) are in balance.
8. Add Strength Training, Cardio, and HIIT
Getting past that plateau of weight loss or increasing the influence of weight loss requires this extra effort.
At this point, it’s human nature to fall into despair and give up. Including an exercise routine or leveling up your routine can get you past that plateau.
Creating endurance while exercising is important to keep you motivated, it takes time and patience.
Especially when looking to lose body fat faster through exercising.
Strength training increases fat loss, helps bones become stronger, leads to a higher metabolism, and decreases the risk of chronic conditions.
Tools used for strength training can be your own weight, free weights, and weight machines.
With free weight exercises, you can use dumbbells or barbells.
Some exercises can be dumbbell squats, dumbbell lunges, barbell squats, barbell lunges.
In addition, kettlebells can be just as diverse with a variety of possibilities that include kettlebell swings, squats, lunges, and within those additional variations.
Cardio, also known as aerobic exercise increases your heart rate and provides overall health.
The type of exercises can vary from easy walking or hips circles to being high-intensity cardio like an aerobics class.
HIIT (High-intensity interval training) is a form of high-intensity cardio with a slower recovery period.
This type of exercise requires explosive body movements and can be in combination with weights or a person’s body weight.
9. Sleep Well
Sleep deprivation can make a big impact on fat loss, research indicates that inadequate sleep can lead to hormones in the body that affect appetite, satiety hormones, and how the body manages fat storage.
It has even been studied that a single night of sleep deprivation can increase the hormone ghrelin, which causes you to be hungry.
Imagine, one single night can increase your appetite so much that you can fall off the wagon from your new goal and start to slowly gain that weight back.
An effective way to improve your chances at weight loss is to get enough sleep, take a good night’s sleep as a part of your weight loss journey.
You need a bedtime routine that allows for a minimum of 8 hours a night. To allow your body to rest, reset and have less stress.
