In a world saturated with quick-fix weight loss solutions, understanding the nuances of a realistic weight loss graph is crucial. This article aims to provide a comprehensive guide to setting achievable goals, understanding the factors influencing weight loss, and adopting sustainable strategies for long-term success.
The Illusion of Linear Progress
One of the biggest struggles as a coach is communicating to clients that they are making progress despite what the scale says. It's important to recognize that weight loss is rarely a linear journey. A real weight loss progress chart from a real person making real progress shows that sometimes you can still be making progress even if the weight loss progress chart doesn’t show a trend immediately (or even for weeks). The scale can play mind games, dictating your day if you let it. Tracking progress is essential, but understanding the factors at play prevents setting yourself up for failure by expecting the impossible. Sometimes it takes just a few days and other times a month to see clear progress on paper. Your body is complicated and doesn’t exist in a vacuum! Even after you’ve “fixed” whatever it is that was slowing down your progress (like poor sleep in the weight loss progress chart above), your body still may have to go through a week of readjustment and recovery to drop the weight again.
Factors Influencing Weight Loss
Several factors influence an individual's weight loss journey, making it unique for everyone.
Age, Sex, and Body Composition
Men tend to have more muscle mass and less body fat than women, leading to a higher calorie burn and potentially faster weight loss. Men will also lose more lean mass and less fat mass, especially initially. As we age, muscle mass decreases, slowing down calorie burning and potentially extending the weight loss timeline.
Starting Size and Body Mass Index (BMI)
People with a healthy BMI (18.5-24.9) may experience slower weight loss compared to those with more weight to lose. Knowing how much weight to target initially can also depend on your starting size. Five to 10 percent of your body weight may be a good place to start-this will vary based on starting size. Those starting at a healthy weight are also more likely to lose a more significant percentage of weight as fat-free mass (muscle) and be more at risk of regaining fat if they rebound. In contrast, overweight or obese individuals are more likely to lose body fat mass.

Calorie Deficit and the Myth of the 3500-kcal Rule
The traditional belief that 3,500 calories equate to a pound of fat suggests that cutting 500 calories daily leads to a pound of weight loss per week. However, this "3500-kcal rule" grossly overestimates actual weight loss and leads people to unrealistic expectations. This is because it doesn't consider important factors such as the physiological changes that occur during weight loss. Eating 3,500 fewer calories does not mean you're exclusively burning 3,500 calories worth of body fat. Muscle mass is also lost, depending on your initial body composition. People with higher initial body fat burn more fat from the energy imbalance versus muscle tissue than those with lower amounts of body fat. Muscle mass is a significant contributor to Basal Metabolic Rate (BMR). As muscle mass decreases, so does the number of calories you burn daily.
The Importance of Accurate Models
Formulas incorporated into online calculators should be based on mathematical models that factor in the body dynamics and physiological changes that occur when the body is in a calorie deficit state. These factors include changes in the amounts of body fat and lean body mass, glycogen, sodium, extracellular fluid levels, and changes in the thermic effects of feeding.
Macronutrient Intake and Diet Composition
While macronutrients, food types, and other factors can play a role, an energy imbalance is often a major contributor (2, 3, 4). If you eat more calories than you need for energy, weight gain can result. Some people believe carbs lead to weight gain, while others think that fat is the cause. Data from the National Health and Nutrition Examination Survey suggests that the percentage of calories from macronutrients - carbs, protein, and fat - has stayed relatively constant over the years (10). As a percentage of calories, carb intake has increased slightly, while fat intake has decreased. However, the total intake of all three macronutrients has gone up. Some researchers claim that low carb diets are more likely to boost metabolism than other diets (11, 12). Research has shown a low carb diet can be effective for weight loss and provide numerous health benefits. However, the main reason it causes weight loss is calorie reduction.
The Impact of Diet Plans
Consider how your current diet is getting in the way of where you’d like to be. Think through your current dietary habits, meal frequency, snacks, how often you eat out, and how these habits impact your goals. We don’t know for sure if either a low-carb or low-fat diet approach will work better than another, but both may effectively promote long-term weight loss.
Realistic Timelines and Phases of Weight Loss
Estimating how long it will take to lose weight helps set realistic expectations for long-term, sustainable weight loss.

Phase 1: Early Weight Loss
The early phase involves significant fluid loss and glycogen depletion. People following low-carb diets may experience rapid weight loss during this stage. You can lose fat quickly but in a smaller proportion. People who follow a low carb, keto, or carnivore diet may experience quick weight loss during this stage as they begin with less glycogen.
Hormonal Influences
Hormones play a big role in what you see on your weight loss progress chart. Most menstruating women I know (including myself) see a spike in weight around our periods. Sometimes it’s before our periods, sometimes during. It varies from person to person. If you have a hormonal issue that PCOS, then expect even slower weight loss than the average person. This means rather than 1-2 lb/week, expect 0.25-1 lb/week on average
Phase 2: The Plateau
Weight plateaus are common and can lead to discouragement. Possible reasons include metabolic adaptations, decreased calorie intake, and burnout from diet restrictions. It's when you may end up getting discouraged and lose motivation. You can lose a high proportion of fat and, as a result, it occurs at a much slower rate. There are a few different theories about why weight plateaus occur. Basically, as you lose weight, your calorie intake often decreases, so weight loss will slow if you’re not adjusting your intake or exercising accordingly. At the same time, your metabolism is adapting to having fewer calories come in by triggering your hunger hormone and decreasing fullness hormones. The second reason is getting burned out and no longer sticking to a diet.
Setting a Timeline
During the initial weeks (1-4), cutting calories may result in a quick weight loss of one to two pounds per week as the body depletes glycogen stores, protein, and water weight. However, starting a new exercise routine may slow initial weight loss due to muscle gain. Plan to work through any plateau or weight gain by making minor, manageable tweaks to your current routine. To encourage future weight management, finding foods, meal patterns, and exercise habits that work well for you and can fit into your everyday life is key at this stage.
Sustainable Strategies for Long-Term Success
Finding what works for your specific needs is the key to weight loss success. Here are some dietitian-approved tips:

Strength Training
Strength training builds muscle, increasing resting metabolic rate and promoting calorie burn even after the workout. It also helps limit muscle mass loss during weight loss, maximizing fat loss.
Increase Protein Intake
Protein helps maintain lean mass, promotes satiety, and stabilizes energy levels. Include good protein sources in each meal, such as grass-fed red meat, poultry, fish, eggs, Greek yogurt, tofu, or tempeh.
Stay Hydrated
Staying hydrated prevents overeating and increases fat loss. Aim for about 125 ounces of water for men and 91 ounces for women per day. Avoid sugary beverages like fruit juice, sports drinks, or sodas.
Set Realistic Goals
Trying to change too many things at once can lead to failure. Instead, set manageable and realistic goals that fit into your lifestyle.
Finding Support
Having someone on your side during a weight loss journey can help hold you accountable and provide motivation. It can be family, friends, or a support group.
The Pitfalls of Rapid Weight Loss
It’s not surprising to want to lose weight FAST. And with summer approaching, you may also be more likely to see an increase in ads targeting quick ways to lose weight easily. While it’s understandable to be drawn in by the promise of losing 10 pounds in two weeks, remember that rapid weight loss is not true fat loss and is most likely not sustainable over time. Some of these promises may also be fad diets that can do more harm than good for your health. It can have undesirable side effects, and as research shows, the more you yo-yo diet, the less likely you are to keep the weight off. You may also lose more muscle mass, slowing your metabolism and making weight loss more difficult down the road.
Monitoring Progress Beyond the Scale
Weight isn’t everything… Here’s an example of a client who’s gaining muscle while losing fat. On the scale, it seems like she’s plateaued. But if we look at her waist measurements, she’s losing inches week over week! A lot of people claim they want to lose weight to “look better” or “be healthier.” Yet despite being able to fit better in pants and seeing their blood test numbers get better over time, they still let their entire day be destroyed by the scale number alone.
Reviewing Daily Intake
- Review your overall daily energy intake.
- Review your total daily protein intake.
- Review your total daily carbohydrate intake. You may need more than you’re getting, particularly right after training sessions or games/competitions.
- Review your total daily fat intake, particularly your intake of essential fatty acids. If you’re noticing a lot of inflammation, you might benefit from increasing your intake of “Eat More” fat sources, and decreasing your intake of “Eat Less” fat sources.
Adjusting Calorie and Macronutrient Intake
- Decrease your client’s intake by about 250 calories a day, by cutting out about 25 to 50 grams of carbs and/or 7 to 15 grams of fat. Or simply remove 1 to 2 cupped handfuls of carbs and/or 1 to 2 thumbs of fats from their daily intake.
- Increase your client’s intake by about 250 calories a day, by adding 25 to 50 grams of carbs and/or 7 to 15 grams of fats. Or simply add 1 to 2 cupped handfuls of carbs and/or 1 to 2 thumbs of fats to your daily intake.
- Increase your client’s daily protein intake by about 25 grams. Or simply add 1 extra palm of protein to your daily intake, and remove 1 to 2 cupped handfuls of carbs and/or 1 to 2 thumbs of fats from your daily intake.
