For example, when it comes to hormones, ghrelin makes you hungry, leptin and other hormones keep you feeling full, Nadolsky says. Thyroid, cortisol, insulin, testosterone, and estrogen all influence how you metabolize and store energy. Meanwhile, genetics have a large influence on both basal metabolic rate (how many calories you burn just to live) and hormone health. While all of these things are impacted by our diet, they’re not only controlled by the way we eat. And, in fact, while sleep, stress management, and, when needed, medication can help regulate other hormone levels such as estrogen and thyroid, our hormones and other physiological processes are often out of our control. And by the way, being able to impact our hormone levels and metabolism with our diet doesn’t always work out in favor of weight loss. As a 2016 review notes, one of the reasons weight loss by way of caloric restriction isn’t efficacious is because “this strategy is countered by the body’s natural physiological response to negative energy balance.” In other words: The body fights back against caloric restriction.

Chronic stress may increase levels of stress hormones such as cortisol in your body. This can cause increased hunger and result in weight gain. If you’re looking to lose weight, you should review possible ways to decrease or better handle excessive stress in your life. Although this often demands substantial changes, even altering small things – such as posture – may immediately affect your stress hormone levels, and perhaps your weight.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
Protein is one macronutrient that can really help fight belly fat. When you eat more protein, it keeps you fuller longer and reduces the hunger hormone ghrelin, helping you slash the total calories you consume in a day. High-protein meals, with 20 to 30 grams of protein each, can also help you burn more calories by raising the body’s metabolic rate. Eat up to three protein-rich meals a day to keep your appetite and cravings in check. Good sources of protein include poultry, lean meat, eggs, fresh-caught fish and other seafood, cottage cheese, and yogurt. Include one or more of these in every meal. Say hello to a slimmer waistline with these 15 foods that actually flatten your belly.
“Getting deep down to the root of why you want to lose weight is a very powerful and eye-opening experience,” she says. “I do this exercise with my clients. I give them a piece of paper and they start at the top with the initial reason they want to lose weight. Often, it starts with reasons like ‘I will look better.’ Under that, I ask them why that is important. Sometimes there are some very deep and powerful reasons that are incredibly motivating like ‘I want to lose weight to travel on an airplane with my husband on our second honeymoon’ or ‘to be able to really play with my kids.’”
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
