Dear Lactnet Friends:

Is this preliminary research to use milk sugar for weight loss???? We'll
have to
see.....

Abstract

BACKGROUND: Galactose consumption as the only carbohydrate source results in
little increase in plasma glucose and insulin concentrations when compared
with
fasting. Lower insulin might promote endogenous lipolysis during meal
absorption, which may facilitate fat loss.

OBJECTIVE: The objective was to test the hypothesis that consumption of an
isocaloric, isonitrogenous galactose drink will result in higher rates of
lipolysis and fat oxidation than consumption of a glucose drink in obese
lactating and nonlactating women.

DESIGN: Seven healthy, obese, exclusively breastfeeding women and 7 healthy,
obese, nonlactating women were studied on 2 occasions according to a
randomized,
crossover, single-blinded design. Subjects received drinks providing
≈70%
of the daily estimated energy requirement, of which 60% was either glucose
or
galactose. The primary outcomes were the rate of appearance (Ra) of glycerol
and
palmitate, and the secondary outcomes were glucose Ra, milk production,
energy
expenditure, and substrate oxidation.

RESULTS: Plasma glucose and insulin concentrations were lower (P < 0.05) and
those of glycerol, palmitate, free fatty acids, and triglycerides were
higher (P
< 0.05) during galactose than during glucose feeding in both nonlactating
and
lactating women. During galactose feeding, glucose Ra was lower (P < 0.01)
and
glycerol, palmitate, and free fatty acid Ra were higher (P < 0.01) in both
groups. During galactose feeding in all women combined, fat oxidation was
higher
(P = 0.01) and protein oxidation was lower (P < 0.01). Milk production,
energy
expenditure, and carbohydrate oxidation were similar between glucose and
galactose feeding.
