A series of four trials was carried out to investigate the effects of caffeine and coffee on the metabolic rate and substrate utilization in normal weight and obese individuals. [] Key Method In the first trial 8 mg/kg caffeine was compared with a placebo in normal weight subjects. Metabolic rate increased significantly during the 3 hr after caffeine ingestion. While plasma glucose, insulin, and carbohydrate oxidation did not change significantly, plasma free fatty acid levels rose from 432 +/- 31 to 848…

Caffeine: a double-blind, placebo-controlled study of its thermogenic, metabolic, and cardiovascular effects in healthy volunteers.
TLDR
The results suggest that lactate and triglyceride production and increased vascular smooth muscle tone may be responsible for the major part of the thermogenic effect of caffeine.
Metabolic effects of caffeine in humans: lipid oxidation or futile cycling?
TLDR
The effect of caffeine on lipid mobilization in resting conditions can be interpreted in 2 ways: lipid mobilization alone is insufficient to drive lipid oxidation, or large increments in lipid turnover result in small increments in cholesterol oxidation.
Effect of caffeine on metabolic and cardiovascular responses to submaximal exercise in lean and obese men
TLDR
Caffeine activates metabolism without inducing major changes in fat/carbohydrate oxidation in lean and obese subjects, and the differences in body fat content seem not to affect the caffeine-induced effects in a submaximal exercise.
daily energy expenditure in lean and postobese human volunteers 14
Single-dose oral administration of 100 mg caffeine increased the resting metabolic rate of both lean and postobese human volunteers by 3-4% (p < 0.02) over 150 mm and improved the defective
Effects of Intake of a Mixture of Thiamin, Arginine, Caffeine, and Citric Acid on Adiposity in Healthy Subjects with High Percent Body Fat
TLDR
It is suggested that TACC may be effective in reducing body fat in obese subjects because of its effect on lipid metabolism.

TLDR
Evidence is provided that metabolic substrate is somehow implicated in elevating oxygen consumption following exercise cessation, and oxygen consumption and FFA levels were significantly greater during and 1 h following exercise, with R values being significantly lower in CA compared to C.

Effects of time-release caffeine containing supplement on metabolic rate, glycerol concentration and performance.
TLDR
TR-CAF and CAF showed distinct pharmacokinetics yielding modest effects on reaction time, yet did not alter glycerol concentration, metabolic measures, or other performance measures over an 8-hour period following ingestion.

Carbohydrate and Lipid Oxidation in Normal and Diabetic Subjects
TLDR
In the group of maturity-onset diabetics, a slight insulin secretion seemed to be sufficient to prevent lipolysis and to allow normal rates of lipid and CHO oxidation in response to glucose load, while in the group on the other hand, the lack of endogenous insulin secretion seems to be responsible for increased lipolytic activity, leading to decreased responses to glucose Load.
THE EFFECT OF COFFEE AND DECAFFEINATED COFFEE ON OXYGEN CONSUMPTION, PULSE RATE AND BLOOD PRESSURE
In 26 experiments on 14 human subjects under basal conditions in which oxygen consumption was measured before decaffeinated coffee was taken and one-half hour and one and one-half hours after,

Plasma free fatty acid concentrations in obesity.
TLDR
The purpose of the present study is to analyze one parameter of lipid metabolism in obesity — namely, the concentration of plasma free fatty acid (FFA = nonesterified fatty acid = NEFA).
