A "class III male living with obesity" with a BMI of 53 kg/m 2: weight 182 kg (401 lb), height 185 cm (6 ft 1 in). He presents with stretch marks and enlarged breasts. Obesity is typically defined as a substantial accumulation of body fat that could impact health. [26]
A tuna (pl.: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae family.The Thunnini comprise 15 species across five genera, [2] the sizes of which vary greatly, ranging from the bullet tuna (max length: 50 cm or 1.6 ft, weight: 1.8 kg or 4 lb) up to the Atlantic bluefin tuna (max length: 4.6 m or 15 ft, weight: 684 kg or 1,508 lb [citation ...
Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. [1] It is reported in energy units per unit time ranging from watt (joule/second) to ml O 2 /min or joule per hour per kg body mass J/(h·kg).
A novice bodybuilder may be able to gain 8–15 pounds (4–7 kg) of muscle per year if they lift weights for seven hours per week, but muscle gains begin to slow down after the first two years to about 5–15 pounds (2–7 kg) per year. After five years, gains can decrease to as little as 3–10 pounds (1–5 kg) per year. [4]
With adequate refeeding and the full restoration of both fat mass and fat-free mass, hunger eventually becomes normalized. However, the restoration of fat-free mass typically takes longer than that of body fat, leading to "fat overshoot" or "overshoot weight," wherein the patient's body fat levels are greater than pre-starvation levels.

Sucrose is an easily assimilated macronutrient that provides a quick source of energy, provoking a rapid rise in blood glucose upon ingestion. Sucrose, as a pure carbohydrate, has an energy content of 3.94 kilocalories per gram (or 17 kilojoules per gram).
Lean muscle is the driver of basal energy metabolism and aids in the use of energy. When sufficient levels of fat are provided, fat will be used by the body as an energy source, but only when there are insufficient levels of protein. An important component of many weight loss/weight control diets is L-carnitine. This is a vitamin-like substance ...
