HORMONE BALANCE FOR WEIGHT LOSS - FACT OR FICTION? - Learn More About How a Lack of Homeostasis Affects the Body and Clients’ Ability to Reach Their Goals

Sep 30, 2026

Hormone balance is examined as a driver of weight change, focusing on how impaired homeostasis disrupts insulin function and links excess caloric intake to insulin resistance. The document explains how overeating and sedentary habits can worsen insulin sensitivity, outlines the “carbohydrate-insulin model” and why evidence is mixed, and summarizes that weight gain and excess energy elevate risks through reactive oxygen species and inflammation. It further introduces cortisol as a stress hormone and discusses how chronic low-grade stress and processed foods can strengthen the stress–obesity link.

Insulin, calories, and type 2 diabetes

Cortisol and stress–obesity connection

HORMONE BALANCE FOR WEIGHT LOSS: FACT OR FICTION? Learn more about how a lack of homeostasis affects the body’s systems as well as your clients’ abilities to reach their goals. BU BBS, ND cells. Consuming excess calories—especially from sugary, calorie-laden processed foods—triggers an insulin response: e hormone tells tissues to take up the fuel. Unneeded calories get converted into body fat. As people grow more overweight or obese, the body’s insulin response starts to malfunction, progressing from insulin sensitivity to insulin resistance, the stage when cells stop responding e􀀝ectively to insulin. Insulin resistance is a key symptom of type 2 diabetes, which may require medication to restore insulin function. e more your clients su􀀝er from overweight or obesity, the worse their insulin sensitivity will typically be, meaning their bodies must pump out more insulin than normal to cope with each meal. Insulin resistance is the end of the spectrum; this is the hallmark of type 2 diabetes. Because higher insulin levels accompany overeating, it’s tempting to ask: Does more insulin cause weight gain? Yes and no. Carbohydrates have the biggest impact on insulin [output. is](output. is) led one group of experts to propose the“carbohydrate-insulin model” of obesity, which broadly states that carbohydrates are speci cally more fattening than other macronutrients. While it’s an interesting hypothesis, the research doesn’t back it up, because eating too much fat also consistently induces insulin resistance and weight gain (Ferrannini et al. 1983; Bodenet al. 1991; Belfort et al. 2005). In short, consuming too 40 AMERICAN FITNESS / SPRING 2019 SPRING 2019 / AMERICAN FITNESS 41 A NEAT Way to Burn Calories Many trainers get too focused on the calories clients burn during their training session and forget about how much they move the rest of the day (Levine 2004) . This other energy expenditure is called nonexercise activity thermogenesis (NEAT), and it actually makes up the bulk of calories burned in a day’s activity. If your clients are sedentary, ensuring they’re getting enough movement during the day should be a top priority. The suggestion for 10,000 steps is a great place to start. In the short term, apps or tness trackerscan be very effective tools for showing clients how inactive they truly are. It can take 8–12 weeks to build new movement habits. Walking to work, taking the stairs, parking as far away from an entrance as possible (where all the free spots are!), or doing a daily or nightly walk with friends or loved ones are all great ways to add more movement into the day. ultimately leads to type 2 diabetes and increased risk of death from all causes. Unfortunately, today’s world of hyperpalatable processed foods available 24/7 makes it di􀀝cult to 􀀜ght o􀀛 the urge to keep snacking. To sum up, weight gain is the most common cause of insulin dysfunction (though not all people with type 2 diabetes are overweight). 􀀞us, when 􀀜tness clients who don’t have diabetes ask you about “lowering insulin”to lose weight, the best approach is to refocus their attention on the root cause—excess body fat. 􀀞at means getting back to fundamentals, reducing caloric input many calories—from carbohydrate or fat—leads to weight gain. Excessive weight gain eventually leads to insulin resistance. In fact, excess energy will endanger any cell because the extra energy ramps up reactive oxygen species and in ammation, scrambling the insulin signal and leading to insulin dysfunction or resistance.

FAQs

How does excess calorie intake relate to insulin resistance?

Consuming excess calories triggers insulin responses; as weight increases, insulin sensitivity can malfunction and progress to insulin resistance, where cells stop responding effectively to insulin.

Does higher insulin directly cause weight gain?

The document states it’s tempting to ask whether more insulin causes weight gain, answering “Yes and no,” and explains that the broader evidence does not support the carbohydrate-insulin model as the sole driver because excess fat can also induce insulin resistance and weight gain.

What is NEAT and why is it important for weight loss?

NEAT (nonexercise activity thermogenesis) represents energy expenditure from movement outside training sessions and can make up the bulk of daily calories burned. Increasing daily steps and routine movement helps build better habits over 8–12 weeks.
