Struggling with contradictory weight loss advice and fad diets that just don't deliver? You're not alone. Abbey Sharp is here to help cut through the noise with science-backed strategies that actually work. As a Registered Dietitian (RD), TV personality, and founder of Abbey's Kitchen, with over 700,000 YouTube subscribers, Abbey brings credible nutrition expertise to the table. Her philosophy? Weight loss doesn't have to be restrictive or complicated. Read on to discover simple, sustainable changes that could transform your health journey.
The Foundation: Understanding Calorie Deficit
"In order to lose weight, you need to create a calorie deficit. Hard stop," Abbey explains. But don't worry—this doesn't mean measuring every Cheerio or logging every bite in MyFitnessPal. According to Abbey, the most important factor in weight loss is actually appetite management, not obsessive calorie counting.
Choosing naturally satiating foods rich in protein, fiber, and healthy fats—what Abbey calls her "hunger-crushing combo"—creates the foundation for sustainable weight loss. With that foundation in place, these smaller hacks can help move the needle without deprivation.
1. Front-Load Your Calories
"Research has shown that eating more of our calories earlier in the day can help with appetite and cravings into the evening," Abbey notes. This contradicts intermittent fasting patterns that push meals later in the day. Our bodies are more insulin sensitive in the morning, and a high-protein breakfast specifically can promote fullness throughout the day. If you usually skip breakfast and eat most calories at night, try shifting those meals earlier.
2. Harness the Power of Retrogradation
It sounds complicated, but Abbey explains this simple science: "When we cool starch-rich carbohydrate-based foods like rice, pasta, and bread, those starch molecules get rearranged into a type of fiber called resistant starch." This resistant starch supports gut health, reduces glycemic load, and promotes longer-lasting fullness. Plus, it decreases absorbable calories in starchy foods by 10-15%—making your calorie deficit easier to maintain.
3. Apply the Pistachio Principle
Named by Dr. James Painter, Abbey describes how "eating pistachios with the shells on prompted participants to eat less of them because the shells acted as a visual cue of how much they ate." This principle works with any food that leaves evidence of consumption—shells, wrappers, or even using small bowls instead of eating from packages. These visual cues promote mindful eating and help you check in with hunger signals.

4. Choose Whole Nuts Over Nut Butters
"Recent studies have shown that the fat in almonds is actually encapsulated by the cell wall, which is hard for our bodies to break down," Abbey shares. This means up to a third of almond calories aren't bioavailable to us. However, processing nuts into butter makes more calories absorbable. Abbey isn't suggesting eliminating nut butter entirely—it's still nutritious—but as a general rule, the more whole a food is, the more work your body needs to do to digest it, which can benefit weight management.
5. Put Out a Veggie Tray Before Dinner
A simple yet effective strategy: "Researchers found that having a high-fiber veggie preload can help with weight management by increasing fullness hormones like GLP-1 and peptide YY," Abbey notes. One study showed that participants who ate a small salad before lunch consumed fewer calories from their main meal. Putting out vegetables while preparing dinner encourages eating nutrient-dense foods when you're actually hungry, potentially reducing intake of higher-calorie options.
6. Make Your Smoothies Thick
"We know that an important trigger for satiety is a stretching of the vagus nerve, which sends a message to your brain to pump out satiety hormones," Abbey explains. Research shows that regardless of calorie content, thicker smoothies make people feel fuller than thinner ones. Abbey suggests making protein shakes "Frosty-style" by adding frozen banana, ice cubes, nut butter, and Greek yogurt for maximum satiety.

7. Increase Your NEAT
"NEAT is all of the energy that you spend throughout the day outside of structured exercise," Abbey clarifies. This includes fidgeting, cleaning, and walking—activities that can burn more calories collectively than gym workouts. Research shows NEAT plays a massive role in body weight, partly because we don't typically compensate for this movement by eating more. Abbey suggests pacing during calls, walking meetings, taking stairs, and using fidget toys to naturally increase daily movement.
8. Lower Your Bedroom Temperature
Poor sleep is linked to higher BMI, as Abbey points out: "inadequate shut-eye can mess with our hunger and satiety hormones, increase our blood sugars and appetite, and decrease our daily energy expenditure." Research suggests the ideal sleeping temperature is 65-68°F (18-20°C), as higher temperatures interfere with restorative sleep. Preliminary studies also indicate that sleeping in cooler rooms may increase brown fat, which burns calories to maintain core temperature and improves insulin sensitivity—an important factor in weight management.
9. Get Morning Sunlight Exposure
"Exposing yourself to sunlight first thing when you wake up helps to support your natural circadian rhythm," Abbey explains, which improves sleep and optimizes metabolic function. Research shows an association between morning light exposure and lower BMI. One study found that 45 minutes of morning light decreased appetite and led to fat loss after just three weeks. Abbey suggests a morning walk to combine light exposure with movement.
10. Take a Short Walk After Meals
"This is an evidence-based tip for reducing post-meal blood sugars and therefore improving overall insulin sensitivity," Abbey notes. Stable blood sugar is critical for weight management due to the relationship between insulin signaling and body fat. When insulin resistance develops, it triggers hunger hormones, leading to increased calorie consumption and abdominal fat gain, which further perpetuates insulin resistance. A quick post-meal walk helps break this cycle.
Simple Changes, Sustainable Results
Abbey emphasizes that these hacks aren't prescriptive—they're options to consider incorporating if they feel manageable for your lifestyle. "For a lot of people, sustainable weight loss comes from a collection of small changes that are so simple and intuitive that they can actually be maintained," she concludes. Choose the strategies that work for you, and remember that consistency with small changes often leads to the most lasting results.
