Jay Shetty interviews fasting and nutrition author Dr Mindy Pelz on strategies she says are supported by science for reducing “belly fat”, improving metabolic health, and building sustainable eating habits. Pelz argues that repeating the same fasting pattern daily can backfire because the body adapts, and she recommends tailoring fasting and eating windows to lifestyle and goals, including earlier cut-offs for evening eating to reduce insulin resistance.
A major theme is blood-sugar regulation: Pelz contends that meal composition and glucose “recovery” after eating matter more than calorie counting, describing a patient example using a continuous glucose monitor to reduce glucose spikes by adding fat and fibre. She cites time-restricted eating research she attributes to Satchin Panda, claiming an eight-hour eating window can reduce metabolic harm markers even with a processed diet.
Pelz also makes broader environmental-health claims, alleging modern exposures to chemicals in skincare and food (“obesogens”) contribute to fat gain and can affect stem-cell development; these statements are presented without detailed sourcing in the episode. She describes a personal trial of higher protein intake (one gram per pound of body weight) that she says increased fat gain for her, and advises listeners to individualise targets. The conversation also turns to women’s health and body image, with Pelz linking restrictive dieting to loss of menstrual cycles among younger women and arguing cultural ideals can push people into hormonal imbalance.
The episode closes on accessibility, with Pelz framing fasting as a low-cost tool for people without access to wearables or expensive health foods.
Dr Mindy Pelz says modern chemical exposure contributes to weight gain, arguing that the body stores toxins as fat, particularly around the abdomen and chest. She alleges women are exposed to “over 200” carcinogenic chemicals daily via skin products and recommends reducing ‘toxic load’ through product and food choices and “different detoxes”.

She claims this is visible “in the UK right now”, alleging children’s stem cells are making fat rather than bone, contributing to kids becoming “shorter than ever before” and “bigger than ever before”.

She claims it can prevent rises in insulin, HbA1c and inflammatory markers such as CRP, and argues the fasting window matters more than calorie counting.
Read this moment →Dr Mindy Pelz says she has seen many women in their 20s and 30s lose their menstrual cycle after restricting calories to match culturally promoted body types. She argues this kind of weight loss can disrupt hormones and that some fat gain may be normal under oestrogen-driven physiology.
